Los Altos Auto Repair

Hello Cayenne here and today we are watching our weight.  Most Los Altos auto owners are all talking gas mileage right now. Better gas mileage. Fewer emissions. CA folks want to save the environment and our pocketbooks.

And we Los Altos auto owners all know — or should know — that preventive maintenance will help maintain maximum fuel economy. But is there something more we can do? After all, some of us Los Altos drivers can’t cut back on our driving, and others would like to do more to economize.

Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from Los Altos to Cupertino to Sunnyvale. And that means buying more gas and producing more emissions.

Of course, your vehicle’s weight isn’t negotiable. And you can’t do much about the weight of your passengers. And this isn’t an article about diet and exercise.

But look around your car. Are you hauling a bunch of unnecessary weight around Los Altos? Do you really need your golf clubs every time you leave your Los Altos neighborhood? Store sports equipment in the garage. Load it when you need it and store it when you don’t. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.

The same goes for anything else in your sedan: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don’t.

Clean out your vehicle. You’d be surprised how much weight you’re lugging around in plain old junk. Toss old papers, leftover food, and regular old dirt. Even if it’s not a lot of weight, you’ll feel better when you get into your car. A good cleaning is also part of good car care.

Now, don’t toss stuff you really do need. You do need that spare tire — the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in the car when you go on a longer trip, but you don’t have to lug it around Los Altos all the time.

After all, are you a driver? Or are you a junk chauffeur?

Lose the junk (unless you are talking dogs bones) and save some money.

Cayenne checking out.

Yes Cayenne has a question, what is that light? 

Okay. You went to your local Los Altos car wash and while your sedan was under the dryer, the check engine light started flashing. Panic! What did you just do? Something is seriously wrong with the sedan! You head for the nearest Los Altos service station, but on the way, the check engine light stops flashing, and just glows red. Hmm. Maybe things aren’t as bad as they seem. You decide to wait until payday to take your sedan in to get serviced. In the meantime, the check engine light goes off. What? You decide the light must be faulty, or that when it comes on it doesn’t mean anything, or that it’s just in your sedan as some sort of scam to get you to pay for unnecessary pricey repairs. You’re glad you didn’t take your car to the Los Altos repair shop and resolve to ignore that engine light in the future.

Whoa! Let’s look at what really happened. Your sedan was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered: there shouldn’t be that much airflow when the sedan engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The check engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the check engine light to stop flashing. The sedan doesn’t need immediate attention; but there was a problem, and it should be checked out by your service professional. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a check engine light, but you should remember that a computer can’t think for itself, it can only follow its programming. It doesn’t know the difference between a car wash air dryer and a serious malfunction in your sedan engine. That doesn’t make it useless. It just means you have to be the smart one.

Being smart doesn’t mean ignoring your sedan check engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your sedan engine. It knows what parameters are normal, and when a reading may indicate a problem. It uses the check engine light to let you know when something isn’t right. It then stores a code in its memory that a technician can retrieve that indicates which reading was abnormal.

The technician uses this code as a starting place to find out what’s wrong with your sedan. It’s like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what’s causing it. It’s probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what’s NOT wrong with you. Fevers don’t accompany stress headaches, ulcers or arthritis, so there’s no sense in testing for those conditions.

Your Los Altos technician responds to a trouble code in your sedan’s computer in the same way. The code doesn’t say exactly what’s wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn’t need to look.

Now, you wouldn’t consider diagnosing yourself with a serious medical problem; good medical advice — unless you’re a doctor. So you shouldn’t consider trying to diagnose your vehicle’s troubles by yourself; good auto advice — unless you’re a trained mechanic.

There are cheap scanners available on the market and some Los Altos auto parts stores offer to read trouble codes from your sedan engine computer for you, but these are really not good alternatives to taking your vehicle to a qualified service center such as Allied Auto Works in Los Altos. Your engine’s computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can’t read an engine computer’s long-term memory nor can they interpret manufacturer - specific codes. That’s why manager Brian Aberg at Allied Auto Works spends a lot of money on high-end diagnostic tools.

It’s as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Los Altos auto parts store isn’t really a money-saver, either, unless you’re a trained mechanic. You’ll end up with a code that tells you a symptom. What usually happens next is that the Los Altos parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It’s actually cheaper to just go to the Allied Auto Works in Los Altos and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it won’t help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good car care is knowing where you can get a problem fixed, and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let’s do it right the first time at Allied Auto Works. In the long run, it’s actually the less pricey choice.

Well I hope I answer that mystery questions we all have when the check engine light comes, including myself.  At least I know it does not mean I am out of dog treats!

Cayenne, til next week

Cayenne has a question for Los Altos, CA motorists: How long have you been enjoying the romantic glow of your check engine light?

Hey, it's not there to create ambiance; it's a warning that something's wrong. (And, by the way, Homer Simpson's fix of covering it with tape is not a good idea.)

If your check engine light comes on, check your gas cap. A loose gas cap can cause a false sensor reading that'll make the check engine light turn on.

Many conditions that trigger the check engine light can hurt your fuel economy. A lot.

If your date's eyes are smoldering in the soft glow of the check engine light, try to think of all the gas money you'll save by getting it fixed. Give Allied Auto Works a call when you are ready: 650.968.7227 and tell them Cayenne sent you!

Cayenne here,

Some Los Altos drivers wonder why Allied Auto Works and other Los Altos auto repair shops charge a fee for diagnostic services.

Think about it: When you hire a local Los Altos HVAC technician to check out a problem with your air conditioner you’ll probably pay a diagnostic fee. When you visit your Cupertino doctor for a health problem, you pay the physician to diagnose the ailment and of course for the tests that go along with it.

So receiving a diagnostic charge at Allied Auto Works for a tricky automotive problem shouldn’t be a surprise. In the Los Altos area, automotive diagnostics can cover quite a range. If you hear a noise in your sedan brakes when you slow down in rush-hour traffic on a busy CA interstate, you pull off the next off-ramp and take a quick visual check. That is usually enough to know what needs to be done. If you’re having an intermittent problem with your sedan engine, however, Allied Auto Works diagnosis may be much more involved.

Much of the Los Altos auto owners’s confusion comes when the problem involves the check engine light. The check engine light comes on when the engine management computer has sensed a problem.

There’s a common misconception among Cupertino, Sunnyvale, and Mt. View drivers that the trouble code tells the Allied Auto Works technician exactly what’s wrong. They wonder why there is a diagnostic charge - because the scanner quickly gave the diagnosis.

In reality, it is not that easy and straightforward. The computer monitors many sensors throughout the vehicle. When one of these sensors has a reading that’s out of parameters, the computer will record a trouble code and turn on the check engine light.

The sedan computer's trouble code just tells the Allied Auto Works technician what engine parameter is out of range – not what’s causing it. The technician needs to determine the underlying problem that’s causing the malfunction.

There are many problems that could cause a troublesome sensor reading for Allied Auto Works customers. The Allied Auto Works service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.

Los Altos service centers subscribe to databases that document possible causes for all the possible trouble codes. The databases outline procedures for confirming a diagnosis and provide the documented repair. These vital databases are specific to each vehicle and engine combination.

Some diagnoses are quick and easy. Others are more involved, time-consuming, and difficult. Of course Allied Auto Works wants to figure out what’s wrong with your sedan and get you back on the road as quickly as possible.

Well I hope that clears up any mystery about Diagnostic for today and until next time this is Cayenne your friendly dog blogger

Cayenne checking in with you,

Under-inflated tires waste gas for lots of folks in the Cupertino area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don't have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from Los Altos to Cupertino.

Always check your tire pressure when you gas up at one of our local Cupertino service stations. If they're low – even just a little bit – bring them up to proper pressure. There's a sticker on the inside of your driver's door that gives the manufacturer's recommended tire pressure.

And don't rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops twenty percent below recommendations. That's severely under inflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Allied Auto Works.

Get some air and save some gas.

 

Hi Cayenne here, today it is all about our techicians and their education and training.

Your car is important to you and keeping it running properly is vital to your Los Altos lifestyle. That's why you're smart to have it serviced regularly at Allied Auto Works in Los Altos. And even though it may just be routine maintenance, you want it done right by automotive professionals.

It's also very important to your Los Altos service center to keep you happy and on the road. You might be surprised at the amount of money our Los Altos auto service center spends annually to make sure our personal and trust service specialists are properly trained.

  Allied Auto Works offers a variety of automotive services for many kinds of vehicles. We need to be current on the latest techniques and parts so that we can give you quality service. Our Los Altos centers subscribe to data services that list the high quality parts and fluids recommended by your manufacturer.

And each service has a checklist of standard procedures. Allied Auto Works technicians follow these procedures so they can safely deliver a consistent level of high-quality service.

Some services at Allied Auto Works require the use of specialized equipment. Allied Auto Works technicians are trained extensively on this equipment so that they can service your car quickly and efficiently.

Classroom, video and hands-on training is provided by the company and outside trainers. It's not only important that personal and trust service specialists be able to perform a given task, they also need to be thoroughly trained in inspection and diagnostic techniques. One of the great services they perform is to detect potential problems before they become serious (and pricey).

The automotive service industry has standards for classifying and communicating problems to auto owners. For example, it's one thing to learn that your manufacturer recommends that you change your serpentine belt every 30,000 miles and another to learn that the belt is on the verge of failure. These standards help you understand the urgency of recommendations, letting you make better automotive service decisions.

CA folks may be interested to know that service technicians (including those at Allied Auto Works) are trained in compliance with federal and local Los Altos laws and regulations, including environmental regulations regarding the disposal of used parts and fluids.

It's the goal of Allied Auto Works to provide fast, courteous service. You should feel free to ask your personal and trusttechnician or one of the managers about your service or for more information about their recommendations.

At Allied Auto Works, well-trained service providers, established procedures, industry standards, and, of course, AutoNetTV, combine to give you the best auto service in Los Altos.

Detective Cayenne here and we are going to diagnose today,

There’s a reason we use the word “diagnose” when we talk about fixing cars in Los Altos. Figuring out what’s wrong with your sedan has a lot of similarities to figuring out what’s wrong with someone who is ill. Vehicles are a mass of complex systems that can produce a variety of symptoms when something goes wrong. As with human diagnoses, a specific symptom may be indicative of a number of problems, and figuring out the specific cause takes training and experience.

Sometimes the diagnosis of your sedan’s trouble comes down to a matter of trial-and-error. This can be frustrating for Los Altos motorists because time and money are on the line. You may feel you should only be paying for repair work. Of course, you only want to pay for the right repair – and a proper diagnosis is part of getting it right. Like at the Los Altos doctor’s office — some of what you pay for is the doctor’s time and effort to figure out what’s wrong with you, not for the actual cure.

The good news is that Los Altos drivers can do a lot to help out their personal and trust Allied Auto Works technician in figuring out what’s wrong with their sedan. Again, the medical office is a good analogy. The more information you can give your doctor about where it hurts, when it hurts and how it hurts, the more quickly he will be able to help you. In the same way, the more you can tell your Los Altos service technician about when the problem occurs, what is sounds like, how often it occurs, where it occurs, etc., the more efficiently he will be able to get you back on the road.

Good auto advice: learn how to talk to your Los Altos service professional.

If fluid is leaking from your sedan, you should note the color of the fluid, where under the car the puddles form, and when they form (e.g. only when it’s parked for a while, only if the engine’s hot, when the weather turns cold, etc.). For example, if your sedan is making an unusual sound, you should indicate where the sound is coming from, what kind of sound it is, and when you hear it (again, be very specific). The more details you can give, the more helpful you will be. “I hear the sound when I turn left” is more helpful than “I hear the sound when I turn.” After a few conversations with your Allied Auto Works tech, you should get a feel for the kind of information he needs.

If you drop your car off, leave a detailed note describing information about your sedan’s problem. A quickly scrawled “Making a funny noise” will only lead to frustration for both your technician and for you. Good communication leads to better car care for Los Altos drivers.

If your sedan is occasionally stalling or sputtering, you may need a little more patience than with other types of car trouble because these types of problems are intermittent. In order to fix the trouble, your tech often finds it helpful to reproduce the symptoms. And if the problem is intermittent, it may take a while to do so.

In these cases, specific information can be invaluable, as it can significantly reduce the time it takes for your personal and trust tech to get your sedan to misbehave. For example, if you can tell your technician that the vehicle only acts up after it’s been driven for 20 minutes and over 50 mph, it will allow him to quickly reproduce your problem, greatly reducing the time it will take for a car diagnosis in Los Altos and then get it fixed.

Good preventive maintenance goes a long way to keeping your car out of the Los Altos repair shop, but if you need to get it corrected, good communication will get you back on the road quickly.

Detective Cayenne signing out, good day.

How do Los Altos auto owners know if an odometer is telling the truth?

Well, back in '86, Congress passed the Truth-in-Mileage Act to protect CA consumers against mileage fraud. It says a CA seller must certify the mileage reported is the Actual Mileage.

To have your odometer checked in Los Altos CA, stop by Allied Auto Works:

Allied Auto Works
Los Altos, CA 94024 650.968.7227

If it isn't, the seller must say why; like maybe the odometer is past its mechanical limits. Some older odometers only go to 99,999 miles and then start over at 0. Or, the odometer has been tampered with, broken or replaced.

If the seller tells you the mileage isn’t accurate, there’s not much chance of putting a good number to it; And there’s the unscrupulous seller who claims the reading is true, but it’s not so. What can Los Altos motorists do?

First, you can go to www.CarFax.com, where for a small fee, they’ll give you a comprehensive vehicle history search on your sedan, showing local Los Altos, CA ownership history, accident reports, total-loss events, manufacturer buybacks, Lemon reports and warranty status.

Los Altos motorists can get a mileage history by checking with the local CA DMV (or wherever you happen to be) and other verified sources looking for inconsistencies in the mileage reported when the car’s bought and sold. If there are signs odometer rollback, now you’ll now.

If so, proceed with caution. Or, negotiate a lower price. Or just walk away. There’s always another.

Good day to all, Cayenne here and today we’re going to be talking about serpentine belts for our Los Altos, CA customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the key device that makes electricity to power the sedan and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you're driving around CA in the summer.

The power steering and power brake pumps are driven by the serpentine belt in most Los Altos motorists' vehicles. Those pumps provide vital pressure that assists your steering and braking.

In many sedans, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Los Altos, CA, the water pump is driven by the timing belt.

The radiator cooling fans on some sedans are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of vital work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of key work, but they’re tough and can last Los Altos car owners for thousands of miles.

Just how long will they last? That’ll vary for each individual car in the Los Altos, CA area. Your vehicle manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection at Allied Auto Works can detect a belt that’s getting close to failing.

Your personal and trust Allied Auto Works service specialist can look at the belt: if it has more than three or four cracks per inch, it needs to be replaced. A deep crack that’s more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? Toss it.

What’s involved in replacing the belt at Allied Auto Works? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.

This pulley is mounted to the engine block with a spring loaded arm. Its essential job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV and the automotive professionals at Allied Auto Works recommend Los Altos auto owners replace them at the same time as the belt. It just makes sense.

What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Los Altos streets. A loose belt might give you a slow, slapping sound.

What do you do if your belt breaks? If you’ve actually had that happen on a busy Los Altos expressway, it can be a little scary. The first thing Los Altos car owners usually notice is that they have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.

Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Open your windows and turn the heater on full blast to provide a little engine cooling. Pull over as quickly as you safely can!

The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car will just shut off. You don’t want that to happen while you’re driving in our local Los Altos, CA traffic.

Remember, Los Altos car owners can avoid this stressful scenario if they replace their sedan serpentine belt on schedule. Ask your personal and trust Allied Auto Works tech to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

Hello, Cayenne here on this hot day in Los Altos and its all about fuel,

Los Altos car owners know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your sedan engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the sedan engine.

Direct injection engines burn fuel more efficiently than conventional sedan engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the sedan engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the sedan engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization. Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage as well as delivering less power to the engine.

Los Altos car owners should understand that fuel injectors are not cheap to replace. Direct injection fuel injectors are even more costly. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, Los Altos drivers will enjoy better fuel economy and their fuel injectors will last for a long time.
