Los Altos Auto Repair

What do you fear?   I fear running out of bones. Hi Cayenne here and we all fear something, even with our vehicles.  Ask just about any driver about one thing they fear seeing inside their vehicle and they'll say it's the Check Engine light coming on. You know, that little light on your instrument panel that is in the shape of a vehicle engine, often accompanied by the words Check, Check Engine, Check Engine Service, or Service Engine Soon.  So yes, today, we will take the fear out of the Check Engine Light.  Let's get barkin'!

There are so many different reasons that light shows up, from something as simple as a loose gas cap to a more serious problem that requires immediate attention. 

The Check Engine light comes on because a component of your vehicle's onboard diagnostics system is telling you something isn't operating normally. Your vehicle has a lot of sensors built in, all tied together by computers.  When the sensors are showing that things somewhere aren't functioning the way they should be, they alert the vehicle's diagnostic computers and tell you something's amiss.

The simple rule is if the Check Engine light is on steadily, it's something you should have checked soon but it's not urgent.  If it's flashing or has turned red or orange instead of yellow, get your vehicle checked out as soon as possible.  If you don't, you may be facing some costly repairs.

Here are a few problem areas that may trigger your Check Engine Light. 

• Something's wrong with the emissions equipment.  Maybe too much fuel is getting into the catalytic converter, or the exhaust gas recirculation system isn't working right.  Because some of these components are expensive to replace, it's worthwhile to have a technician look at your vehicle sooner rather than later.
• Your ignition system isn't working right.  That means spark plugs, coils, and wires.  If your engine is misfiring, that could translate into an illuminated Check Engine light.
• The transmission isn't behaving the way it should.  The transmission works in tandem with the engine, so if a sensor sees something wrong there, it will tell the vehicle to turn on the Check Engine light.

As you can see, there are many things that can cause the light to come on, and when it does, it really is a good idea to find out why.  When you bring your vehicle in, we have an electronic device that can read a code or multiple codes stored in your vehicle's computers.  That will provide the technician with clues pointing to the cause of the trouble and helps pinpoint where that trouble is. 

I leave you with this thought,

Fear makes the wolf bigger than he is. ~German proverb

Hello, Duke here on this beautiful spring day.  Most of us look forward to spring because the days are longer, the weather's warmer and we can finally get our vehicles into warm weather mode.  Here are a few things that will breathe fresh energy into anyone's car, SUV, truck or van.  Remember, dogs love car rides, so let make sure they are spring ready. 

The first thing is a good cleaning, especially underneath. If you live where salt and brine are used on the roads, it's important to get that off.  One thing to note… if you hose off your undercarriage, be careful not to get your spark plugs/wires wet.  You could notice your vehicle running rough, plus the Check Engine light may come on. It usually dries out quickly, but if the engine light stays on for more than a couple of days, have your service facility check it out.

Next, replace your windshield wipers.  They've taken a beating through the winter. New ones will have fresh rubber and you'll see clearly (and safely) out your windshield again.

Have your brakes inspected.  That salt doesn't do your brake's metal components any good.  Have a technician make sure your pads and rotors are clean and properly lubricated so they can stop you when you ask them to.

Speaking of wheels, it's a good time to have your tires checked, too.  Road debris and potholes can take a toll on tread and sidewalls. It may also be a good idea to have a technician check your alignment since you likely have hit something pretty hard on a patch of rough road at some time during the winter.

Make sure your tire pressure is appropriate for the rising temperatures. As the outside air warms up, your tire pressure climbs without you adding any air.  Make sure it's what the manufacturer recommends.

Finally, treat your vehicle's interior to a thorough refresh.  Those floor mats and carpets may be white with salt; clean 'em up.  Get rid of wrappers, drink lids, empty water bottles and anything else that's fallen down.  And if you need to, have your upholstery cleaned so it looks and smells new. A clean exterior is nice, but since you spend your time inside your vehicle, it'll feel even better when your cabin is sparkling fresh.

Ever wonder why us dogs love car rides so much?  Well, Dogs love a good car ride because it feeds into their sense of adventure and love of a good hunt. It mimics their instinctual roots of riding in a pack, which brings them comfort and even a type of euphoric high. Riding in the car allows a dog to explore new sites, sounds and smells.

Cayenne here and today I am going to steer you in the right direction with power steering service.  So don't turn left or right but steer straight ahead and get barkin'!

Today we're going to talk about power steering service in Los Altos. If you took an informal poll around Los Altos, you'd probably find that most vehicle owners have never heard of power steering service. That's not surprising. Even though power steering is standard on every vehicle, most people in Los Altos aren't aware that it needs periodic service.

If you're younger than a certain age, you've probably never driven a vehicle without power steering. To get an idea of the difference; if you've ever cut a board with a hand saw, you know it's a lot of work. Using a power saw is easy-peasy by comparison.

Without power steering, your arms have to do all the work to steer the wheels, and that's hard, especially around downtown Los Altos. That's why old cars had such big steering wheels: to get enough leverage to steer.

Most vehicles in Los Altos have a hydraulic power steering system. The serpentine belt from the engine powers a pump. The pump pressurizes the power steering fluid. This actuates a hydraulic cylinder that provides power to help steer.

Some vehicles in Los Altos use an electric pump to pressurize the fluid rather than a belt-driven pump. We're also seeing vehicles with electric motors providing the power assist, not using power steering fluid at all. We'll see a lot more electric systems as more hybrids and electric vehicles hit the market.

At least for now, the vast majority of power steering systems use power steering fluid that needs to be serviced. The fluid needs to be changed for a couple of reasons. For one, it attracts moisture. Water has different hydraulic qualities than power steering fluid, and that makes a difference in steering performance. Water is also corrosive and can damage power steering components. The fluid also just gets dirty and needs to be changed. Removing the old fluid and flushing out the system gets rid of dirt and deposits. The clean, fresh fluid lubricates and provides better corrosion protection.

So ask your Los Altos service advisor at Allied Auto Works or check your owner's manual to see when power steering service is recommended. It'll extend the life of your power steering components.

Here is my joke of the week steering related of course,

Good day, Duke here and today we are going to filter through a very important part; the Fuel Filter.  There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.

Fortunately, a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Allied Auto Works can help you know what's scheduled to be taken care of.

Some of us in Los Altos, CA, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention and addressing small problems before they get big. Let's take the fuel filter, for example.

You may not know this but the median age for private vehicles on our Los Altos, CA, roads is over nine years. When vehicles get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine, it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Los Altos, CA, freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough, your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element, so dirt ends up in the engine. We've already talked about how expensive that can be.

The fuel filter is even very important for newer vehicles. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner's manual. Your Los Altos, CA, service advisor at Allied Auto Works can tell you as well. It's usually around 30,000 miles (50,000 kilometers) or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.

It's good to know that your Los Altos, CA, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Allied Auto Works as your ally - and maybe even your memory.

I leave you with my car joke of the week ,

Hi, Cayenne here and spring is in the air; soon the days will get warmer.   There's nothing that radiates cool like a vehicle radiator that's helping to keep your engine running at the proper temperature.  You don't have to baby it, but you can't simply ignore it, either.   Let's take a quick dive under the hood to let you know what the radiator is doing. 

It takes the heat your engine produces and moves that heat outside.  It's not an easy job and heat is an engine's number one enemy.  Now that you're thinking how nice you want to be to your radiator, we have a couple of ideas how you can take care of it.

The easiest thing is to pay attention to your vehicle's temperature gauge. If it gets in the "too hot" or "not hot enough" range, have it checked out soon.  Make sure your coolant is kept at the correct level and if you see a trend that you have to add coolant more than a couple of times a year, you might have a leak.

Even if there are no obvious problems, every couple of years or so, consider taking your vehicle in for radiator maintenance.  A technician can run a pressure check for leaks and ensure that the thermostat and radiator cap are working correctly.  The technician will check that fans are running like they should so they can move air over the radiator and heat away from the coolant inside.

Ask your service advisor when you should have your radiator flushed and coolant replaced according to the manufacturer's recommended intervals.  In addition to cooling, coolant has corrosion inhibitors which stop working after a while.  Without those corrosion inhibitors, the inside of your radiator can literally start rotting away.  Keep in mind that the coolant level must be kept at manufacturer's specifications since if those corrosion-preventing chemicals aren't touching the metal, they're not preventing corrosion. 

Different vehicles use different coolants, so your service facility will make sure yours is getting the correct one.  

Keep your coolant system happy and one day, maybe you can order up a custom license plate, "RAY-D-8."

Hey Duke here, and you know I love the grinding sound when I enjoy one of the Wagu Rib Eye steak bones I get once in a while, what a beautiful sound and tastes good too.  But what if your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you and that is not a good sound.   So listen to what it's saying and you could avoid a much more costly repair down the road.  So let's grind our way into this important noisy subject and get barkin'!

Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening.

Other causes of grinding while turning can be problems with the suspension in the front.  You may have a failing CV (constant velocity) joint.  It could be your brakes are partially engaging while you are turning.  That metal-on-metal sound is never a sign that things are working just the way they're supposed to.

To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all.  Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared!

Hi Cayenne here, and today we are going to bark about the ongoing training our technicians receive at Allied Auto Works to keep up with the ever-changing world of the automobile. 

When your vehicle breaks down in the Los Altos, CA, area or just needs some routine service, it can make you a little nervous. Because your vehicle's so important to your life, you need to be back on the road as soon as possible — with the problem fixed right the first time.

We've been checking into some of the training our Los Altos, CA, technicians receive, and we're very impressed. It's amazing how much knowledge and skill go into diagnosing and repairing a modern vehicle. So it's not like when your uncle worked on his hot rod over the weekend.

Today there are four-cylinder engines around Los Altos that make more power than the V-8s in luxury cars did 20 years ago. A new V-6 Toyota Camry could beat Sonny Crocket's Ferrari in a race to 60 mph/97 kph.

Our engines are more and more powerful. And they're so reliable. This is all due to engineering. But the benefits come to Los Altos drivers at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.

Then there are the electronics. Some vehicles on CA roads have several networked computers controlling most of the engine functions and many other vehicle functions as well. Los Altos drivers take all of this sophistication for granted – but somebody has to fix it when it breaks.

It's a real challenge for the pros at Allied Auto Works and other Los Altos auto service centers to keep up. It requires a high level of commitment on the part of the auto technician and the service center. In addition to the training, there's the financial commitment to purchase the diagnostic and repair tools as well.

So where do Los Alto's technicians go for training? There are many sources. It's usually a combination of formal classroom training, training provided in the service center by auto parts and equipment manufacturers, online courses and home study courses. There are many independent certifications available all the way up to Master Technician.

Service centers in Los Altos, CA, have a lot of other resources available.  No one can know everything, so service centers like Allied Auto Works subscribe to data services, technical libraries and even online communities that can help them when they run into a difficult problem.

It's like those medical diagnosis shows on TV. Here are the symptoms. What's the diagnosis and treatment? Diagnosis is every bit as much an art as a science. Los Altos drivers want everything to be simple, straightforward and cheap – and sometimes, it just isn't.

So, be more relaxed next time you take your vehicle in. You can trust the professionals at Allied Auto Works. You're in good hands. The more you know, the more comfortable you can be with your automotive service decisions at Allied Auto Works.

Hello, Duke here, and this week I am going to bark tips on your serpentine belt.  So buckle up, and let's get barkin'.

The technicians at Allied Auto Works know your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some cars, it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some cars in Los Altos have two serpentine belts.

The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt), and the idler pulleys are together known as the accessory drive system.

Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your vehicle manufacturer has a scheduled belt replacement interval. The team at Allied Auto Works in Los Altos can inspect your serpentine belt for wear and get it replaced if it’s time.

Give us a call.

Here is my joke of week, of course belt related,

What do you call a belt made of $100 bills?

A waist of money.

Cayenne here and you probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.  So today, we will bark about your vehicle sensors and how they adjust to those weather road conditions.......let's get barkin'

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle and how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems are important to ensure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Here is my quote for the week in regards to the weather.

Don't knock the weather; nine-tenths of the people couldn't start a conversation if it didn't change once in a while. ~Frank M. Hubbard

Hey, it's the Duke and I just got back from nice run, breathing in the fresh, clean air.  But have you ever gotten in your vehicle and said what is that awful smell?  Don't blame it on the dog.  It is probably your vehicle with that rotten egg smell.  So today we will crack the mystery out of that foul smell (no yolk intended).

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another word that begins with S. - Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up. 

If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe.

There's another possibility, but it's usually only in stick-shift vehicles.  That's leaking old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance.  Once the cause is found, repairs made and/or parts replaced, the smell should go away fairly rapidly.

I leave you with my rotten egg joke of the week,

Why can't a rotten egg become a comedian?

He only has bad yolks
