Good day, it's Cayenne again and today we will bark all about PCV Valves and the service they need.  So let's get barkin!

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at Allied Auto Works. At high speeds on CA freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.

This is much better for air quality and improves fuel economy also. (Budget-conscious Los Altos drivers take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets  gases out of the engine, but won't let anything back in. Over time, the vented gases will gum up the PCV valve and it won't work well. That can lead to all of the problems I've already described, oil leaks, excessive oil consumption and decreased fuel economy.

Fortunately, it's very easy to test the PCV Valve at Allied Auto Works in Los Altos and quick and inexpensive to replace. Even so, it's often overlooked because many Los Altos vehicle owners don't know about it. Check your vehicle owner's manual or ask your Allied Auto Works service advisor. If this is the first time you've heard of a PCV valve, you might be in line for a replacement.

There's another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That'll need to be replaced at Allied Auto Works when it gets dirty.

Please ask your Los Altos service advisor Matt or Travis about your PCV valve. For the price of a couple of burger combo meals in Los Altos, you can avoid some very  expensive engine repairs.  Til next week with Duke, this is Cayenne

Well hello, it's Duke and I am keeping a watch on your Check Engine Light.  Are you???  Let's get barkin about what to watch out for!

Did you know that most of the cars driving around Los Altos, CA carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Los Altos area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Los Altos drivers know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Los Altos drivers when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Allied Auto Works in Los Altos to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your friendly and knowledgeable technicians at Allied Auto Works have special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

  Stop by if you're check engine light is on and tell them Duke was keeping a watchful eye for you.

Cayenne here today and here's a question for all my Los Altos neighbors :

 How long have you been enjoying the romantic glow of your check engine light?   Well that is what we will focus on today, let's get barkin'!

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.)

Many conditions that trigger the check engine light can hurt your vehicle. 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 areready and tell them Cayenne sent you!

It's Duke and do you believe that today's sophisticated and modern vehicles are maintenance free?  Well today we will bark about this and find out the truth......let's get barkin'!

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern cars are so reliable, they are virtually maintenance free".

Any good myth has some elements of truth. No offense to Los Altos Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Los Altos.

• Some cars in Los Altos no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts up in the valve train that didn't even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they've always been.

So the maintenance mindset is still important for car owners in Los Altos if we want our vehicles to last a long time. The checklist may change over time, but there'll always be a check list.

Your friendly and professional service advisors, Matt & Travis at Allied Auto Works can answer any questions you have about your vehicles maintenance schedule.

Cayenne here and today we will do a balancing act.  Wheel balancing and tire rotation that is!  So let's get barkin!

Los Altos drivers want their tires to last as long as possible. Two ways to extend tire life are wheel balancing and tire rotation.

When wheels are out of balance, they wobble and vibrate. That makes the tires wear in a cupping pattern. If a front wheel is out of balance you'll feel it in the steering wheel. If it's a rear wheel you'll feel it through your seat. To fix this, your technician at Allied Auto Works puts weights on your wheels to balance them out.

That brings us to tire rotation. The front tires on a vehicle wear out faster than the rear tires. As they push through turns, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.

Proper tire inflation will also help Los Altos folks' tires last longer. Under-inflated tires wear more on the shoulder and may even overheat. This could cause tire damage or a blow out. Over-inflated tires wear too fast in the middle.

Four wheel drive trucks and SUV's tend to wear their tires more unevenly so rotation is even more with them. Give Allied Auto Works a call to get our recommendation for your vehicle.

See your owner's manual or ask your service advisor at Allied Auto Works for your recommended tire rotation schedule. It's usually every 5,000 to 8,000 miles.

Tires are one of the most important safety components on your vehicle. Take care of them and they'll take care of you. 

This is Cayenne and til next week check in with Duke !

What time is it???   Time to check your intervals with me Duke!  Let's get barkin!!! 

Part of the engineering that goes into designing a vehicle is testing the components to ensure that they meet durability and safety standards. Because of this, manufacturers have a good idea as to how long the parts in your vehicle will last under normal driving conditions. For this reason, they give us guidelines to follow regarding how often to inspect the various parts and systems on our vehicles.

Vehicular components are required to meet certain standards. The government mandates some of these standards. Others are set by the auto industry. Recommended car maintenance schedules are designed to help Los Altos vehicle owners maintain these standards. Disregarding routine maintenance or procrastinating preventive maintenance will result in lowered performance and reduced safety for a vehicle.

Maintenance schedules are designed to ensure three areas of automotive performance for Los Altos drivers: protection of the vehicle itself, efficiency, and safety.

Protection

Your vehicle's components need protection from dirt, road damage, rust, corrosion and fuel and combustion by products. Protective components include filters and fluids.

Most of the fluids in your vehicle are there to keep the vehicle running smoothly and to protect the vehicle from corrosion, damage or harmful contaminants. These fluids need to be changed regularly in order to continue protecting your vehicle.

For example, motor oil lubricates your engine, which keeps it running well, but it also contains detergents and other additives that clean your engine and protect it from corrosion. Your vehicle's engine was engineered for best performance with a specific weight and type of motor oil. Los Altos drivers should always be careful to use the right motor oil for their engine.

Over time, the  additives in motor oil are depleted, and the oil becomes contaminated by dirt, water and waste gases from combustion. So in order to keep your engine clean and to continue to protect it from corrosion, the oil has to be changed periodically.

Efficiency

Over time, your vehicle's systems will get dirty and parts will wear down. Cleaning dirty systems and replacing worn parts will improve the efficiency of your vehicle, which is usually measured in terms of and power output.

For example, your fuel system components gradually get clogged up with gum and varnish from gasoline. This restricts fuel flow, which lowers your engine's efficiency. Gas mileage drops as a result. Cleaning your fuel system will restore and improve gas mileage.

Safety

Some of your vehicle's systems must be maintained for safety reasons. Your brakes are a prime example of this. Brake pads and brake fluid need to be replaced in order to ensure good braking power. Poorly maintained brakes lead to accidents.

Your owner's manual is your first resource when it comes to knowing when and how to maintain your vehicle. Of course, you can consult with your Allied Auto Works service advisor. He can give you good auto advice on how to adjust your service schedule to account for climate, local road conditions and your driving distances.

Beyond routine maintenance, your vehicle also requires regular inspections. These inspections are usually recommended at specific mileage intervals, like fifteen or twenty thousand miles. The interval is based on the known life expectancy for particular components in your vehicle. Regular inspections will identify vehicular components that need to be repaired or replaced before damage is done to the vehicle or safety is compromised. They are also designed to safeguard the efficiency and performance of your vehicle.

The multi-point inspection that comes with a full-service oil change does not cover all of the regular inspections your vehicle needs for peak performance and safety. Check with the automotive professionals at Allied Auto Works in Los Altos to find out what additional inspections your vehicle needs and how often. Good car care requires regular and consistent maintenance. But good maintenance pays for itself in better and fewer repairs. It may even save your life.

Well I am  on a schedule too and it's time for me to say goodbye for this week.  Tune in next time with Cayenne and never stop learning!!!

Can you see me, it is Cayenne and today we are barking about Headlamps! 

If you've ever been driving around Los Altos and had a headlamp go out, you've probably just wanted to replace the bad bulb. If your car uses halogen headlamps, they dim over time. So if you just put in one, they won't have the same brightness which can be distracting and will affect your field of vision.

To have your headlights inspected, visit us at Allied Auto Works. We're at 2073 Grant Road in Los Altos, CA 94024. Or give us a call at 650.968.7227.

Experts at Allied Auto Works recommend replacing your halogen headlamps every year. It's easy to remember if you do it when daylight savings time changes in the fall. That way you'll have bright headlamps for those long CA winter nights.

There are other types of headlamps in addition to halogen. There are the old standard bulbs that have been around for decades. These are OK, but you can usually upgrade to halogen. They cost a little more but you can't believe the difference. If you do a lot of night driving you might want to use a premium halogen bulb that filters out the yellow hues and gives a very white light that's a lot like daylight.

You may have noticed those bluish headlights on luxury cars. They are high intensity discharge or, HID lamps. They really light up the road. You can upgrade to HID on some vehicles. These cost quite a bit, but they'll last for the life of your car. If you want your friends to think you have HIDs, you can get halogens with a bluish tint - no one needs to know.

Seriously, though, night driving is all about reaction time – time to stop – time to get out of the way. You can't react to what you can't see. You need headlamps that'll give you a good view down the road and good peripheral vision as well. And your headlights need to be aimed correctly so you can see, and also to keep your lights from shining off into on-coming traffic.

You may have seen older vehicles with headlights that are awfully dim and maybe even yellow. That's because the plastic headlight lenses have gotten cloudy and yellowed with age. They can be replaced, but many Los Altos service centers offer a service to restore the lens that's a lot cheaper.

You can't drive if you can't see. AAA reports that nine out of ten vehicles have dirty or yellowed headlamps. So run the window squeegee over your headlights when you gas up to clear the dirt and bugs. Get your lenses restored if they need it and don't forget to replace your standard or halogen bulbs every fall.

Hope this makes everything crystal clear!

ALERT, ALERT!  Duke here and I'm in a hurry today to get what Emergency Items you need in your vehicle!  Let's not waste time and get barkin!

Local Los Altos roadside emergencies can range from a flat tire downtown to being stranded in a snowy ravine for three days. So you may want to consider a basic emergency kit to keep in the car at all times and a travel kit tailored to a specific trip.

Your close-to-home kit for around Los Altos would have some basic items to work on your car: everything you need to change a tire, gloves, a couple quarts of oil, some antifreeze and water. A can of tire inflator is a great temporary fix for minor flats. You'll also want jumper cables or a booster box, flares, a flashlight and some basic hand tools.

Now for your comfort and safety: a first aid kit, drinkable water, high calorie food (like energy bars), blankets, toilet paper, cell phone, towel, hat and boots. Keep some change for a pay phone, emergency cash and a credit card.

People who live in areas with frequent severe weather or earthquakes may want to carry provisions for longer emergencies.

For trips away from home, consider the weather and geography as you assemble your emergency supplies. You'll need to have a source of light and heat and will want to provide protection against the elements as well as adequate food and water for everyone in the car.

Always tell people where you are going and have a plan for checking in at waypoints. Then if you run into trouble, you can be reported missing as soon as possible and rescuers will be able to narrow the search area.

The key to safe travel is to keep your vehicle properly maintained, plan ahead, and let others know your itinerary.

Remember safety never takes a day off,

Hi it's me again Cayenne and today I am sticking my nose in about how to steer right......so let's get barking!

Virtually all vehicles come with power steering so many Los Altos drivers have never driven a car or truck without it. Power steering assists you when you turn your vehicle steering wheel. Without it, it would be very hard to steer.

Now this power assist comes in a couple of forms. In recent years, a lot of vehicles have an electric motor that reduces steering effort and helps improve performance and handling.

The other kind of power steering is hydraulic. This is the kind most older CA vehicles, and a lot of newer ones, have. Power steering fluid is pressurized by a pump and is used to assist steering. Of course, vehicles need the right amount of fluid in the system. If it's too low your steering is affected and you could damage your vehicle pump.

Also, power steering fluid can become corrosive over time and damage the pump, hoses and connectors; leading to leaks and repairs. Power steering service at Allied Auto Works in Los Altos includes removing the contaminated fluid and replacing it with fresh fluid.

A word for Los Altos drivers about power steering pumps: Some are powered by an electric motor. Others are driven by the serpentine belt. A worn serpentine belt stresses all of the vehicle components it drives, including the power steering pump, so replace the belt at Allied Auto Works as advised to avoid undue repairs.

Losing your power steering while driving in Los Altos can be unsettling – just remember that you can still steer, it'll just be harder. Check with your service advisor at Allied Auto Works to see if it's time to service your vehicles power steering system.

In addition to power steering service, at Allied Auto Works we offer comprehensive automotive services.

Give us a call and let us know Cayenne sent ya! 

Til next week, this is your all knowing nose,

Hi Cayenne here and today we will bark about towing limits when you are driving around town.  I had a trailer full of bones the other day and I did not realize I was over my weight limit so I thought I would share this with you today!

Some Los Altos drivers figure that anything they can attach to their trailer hitch can be towed by their vehicle. Nope. If you're going to do any towing around Los Altos, you should be aware of safety issues, CA towing laws, and potential liability.

Understanding tow ratings is important for safe towing. A tow rating is the weight limit that your vehicle can safely tow. They calculate the tow rating for every vehicle, but different options on the vehicle can affect that rating. Los Altos drivers need to read the towing section in their owner's manual to get the specific tow rating for the vehicle they own.

Your trailer hitch also has a weight limit, and it may not match the tow rating for your vehicle. Your vehicle may be rated for 10,000 pounds, but if you have a 2,000-pound hitch limit, you shouldn't be towing more than 2,000 pounds. If you tow a 10,000-pound trailer on that hitch, it could break free and you would be liable for any resulting damages.

Another example, one popular pick-up truck has a tow rating of 10,300 pounds. But in the owner's manual, it specifies that a sway control device be used for trailers weighing over 2,000 pounds and that a weight-distributing hitch is required for trailers over 5,000 pounds. If the vehicle owner tows a 6,000-pound trailer without a weight-distributing hitch and ends up in an accident, the owner will be held liable for not complying with the towing requirements in CA.

Los Altos auto owners also need to keep in mind that tow weights include the weight of passengers and cargo inside the tow vehicle. So if your tow rating is 7,000 pounds, and you're carrying 700 pounds of passengers and cargo, you can only tow a trailer weighing up to 6,300 pounds.

Two numbers that Los Altos drivers should be aware of are the GVWR and the GCWR. These codes are usually imprinted on the inside of the driver's side door. GVWR stands for gross vehicle weight rating. Take GVWR and subtract the total weight of the vehicle, and you have the maximum weight the vehicle can safely carry in passengers and cargo. GCWR stands for Gross Combined Weight Rating. Take that number, subtract the weight of the tow vehicle and the trailer, and you have the maximum weight of passengers and cargo that the tow vehicle and trailer together can safely carry.

This may seem a bit complicated, but you ignore these ratings at your own peril. If you haul or tow loads over the maximum ratings around CA, you become liable in event of an accident.

Local Los Altos laws require that safety chains be attached when towing a trailer. Some CA jurisdictions may require trailer brakes as well. Others mandate trailer brakes only in certain situations. If you are going to tow a trailer, you should find out the local Los Altos laws regarding trailer brakes, hitches, as well as weight and length restrictions.

To tow safely, CA drivers also need the proper tires on the tow vehicle. Tires need to be in good condition, with adequate tread, and they need to have a load rating high enough to handle the weight of the trailer. Your trained Allied Auto Works tire professional can help you select the right tire to use when towing around Los Altos.

Your 's owner's manual is your primary source for auto advice regarding towing since it is specific to your vehicle. Be sure to read it carefully before doing any towing. And as always, keep your preventive maintenance up-to-date and practice good car care to ensure the safety of your vehicle on the road—especially when pulling a trailer.

Well until next week, this is Cayenne!
