Cayenne here, and as the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator.  So today, we will bark all about alternator problems you might encounter as the weather gets colder.....brrrrr.

The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys. 

In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move like they do when the weather's warmer.  With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery with a little less power to start the engine when it's cold.

You may have a warning light on your instrument panel that looks like a battery.  If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it's complicated. 

Pinpointing the cause involves testing the battery and charging system with diagnostic equipment.  If it does turn out to be an alternator, there are options besides replacing it with a brand-new, original equipment part.  Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather.  Take care of your charging system and it will take care of you.

Hello, Duke here, and today we are all going to get on board and take the train......Drive Train Service, that is.  So let's get on the right track and start barkin' all about Drive Train Service at Allied Auto Works.

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive: front-wheel drive, rear-wheel drive, all-wheel drive, or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.

Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, protected by an airtight rubber boot.

Allied Auto Works' service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise in your wheel wells when you turn, you may have a damaged CV joint. A damaged CV joint should be replaced.

Rear-wheel drive vehicles generally have a transmission in the front of the car and a differential in the back. A driveshaft (it looks like a long tube) connects the transmission to the differential. Some vehicles may have a two-piece driveshaft connected to the differential with universal joints or U-joints. Again, the differential is connected to two half-shafts that go out to the wheels.

Allied Auto Works service on the drive train on a rear-wheel drive vehicle starts with servicing the differential. It will need its fluid drained and replaced regularly. The seals on the axles should also be inspected for wear or leaks. Leaking or damaged seals may mean the axle needs to be serviced. Also, U-joints can wear out. If you hear clunking or feel a jolt when you shift into drive or into reverse, it could indicate a driveline problem.

All-wheel drive vehicles provide power from the transmission to all wheels, instead of just to the front or rear. The advantage is that the vehicle can adapt to different driving conditions and transfer more power to the front or back wheels as needed. The disadvantages are that the driveline is more complicated, and the vehicle weighs slightly more.

Many all-wheel drive vehicles are based on a front-wheel drive setup. They also have a differential in the rear and one in the center of the vehicle, allowing power to transfer to the front and rear. A shaft runs from the transfer case to the center differential, and another from the center differential to the rear differential.

An all-wheel drive at Allied Auto Works involves servicing ALL of the differentials and inspecting the joints and seals for wear, leaks, or damage.

Four-wheel drive vehicles are rear-wheel drive vehicles that have the option to transfer power to the front wheels. In other words, they can be either rear-wheel or four-wheel drive vehicles. These vehicles are specifically designed for the harsh driving conditions Los Altos drivers encounter off-road. The driveline in a four-wheel drive vehicle is similar to that of an all-wheel drive vehicle. The center differential, however, is a transfer case. Maintenance requires servicing the differentials and the transfer case and an inspection of the joints and seals.

Los Altos auto owners would be wise to check with their owner's manual for recommendations on how often to service their vehicle drive train. It's also good auto advice to check with your friendly and knowledgeable Allied Auto Works service advisor. You may live in an area in CA where weather or driving conditions require more frequent servicing of the drive train.

Good car care at Allied Auto Works in Los Altos always includes taking care of your driveline. Without it, your vehicle becomes a very large paperweight.

Hi, Cayenne here, and today I have some tips for you regarding your Serpentine Belt Tensioner, so let's buckle up and bark into this subject now.

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. At Allied Auto Works, we know that the service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prevents the accessories from spinning properly, leading to premature wear and noise for Los Altos drivers.

Your vehicle manufacturer has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner, and any idler pulleys your car might have. Your friendly and professional Allied Auto Works service advisor can inspect your system and let you know if it’s time for a replacement.

Give us a call today and tell them Cayenne sent you.

I leave you with my belt joke of the day,

When I go out in the duck blinds, I love when all my ducks all lined up.  It makes my job easier.  Well, when your car is all lined up, it makes driving a pleasure.  So today, we will bark about alignment and making sure your car is all lined up.  So let's get barkin' and walk the line.

When you head down a straight road, does your vehicle pull to one side?  Do you feel a vibration in any of the wheels? If you've noticed any of these things, it's probably time for you to get your wheel alignment checked.

When your vehicle left the factory, its wheels were parallel to each other and perpendicular to the ground.  That maximizes traction for good steering and braking. Every time you take your vehicle on the road, normal wear and tear will affect your alignment. Hit a bump, a pothole or a curb, and all those little knocks will add up

Bad alignment not only can cause your steering wheel to pull unevenly, it can also wear your tires out a lot faster than they should. In fact, if you look at your tires and see one side of the tread is a lot smoother than the other, it could be another sign of bad alignment.

Since different problems can cause similar symptoms, the first thing our trained technician will do is test drive your vehicle. Then, they'll check the front end and steering linkage as well as look for tire wear.  Then, the technician will put your vehicle on a lift and use computerized diagnostic equipment to measure alignment angles so they can precisely align your vehicle's components.

There are different kinds of alignments.  One is a front-end alignment that aligns components of the vehicle's front axle.  Another is a thrust alignment that makes sure the front wheels are lined up with the direction the rear wheels are pointed.  A third type is four-wheel alignment which is usually used on all-wheel drive and  4-wheel drive vehicles.  It's also recommended for front-wheel drive vehicles that have independent rear suspensions.  It makes sure the angles of all the wheels are where they should be relative to each other and also the vehicle's body or frame.

Your steering wheel should be perfectly centered if you are heading straight down the road, so the technician will adjust it so it is. Finally, they'll take your vehicle back on the road for a final test drive to ensure it's performing the way engineers intended.

Your service adviser can recommend how often you should have your alignment inspection since it depends on the type of vehicle you drive (SUV, sporty car, etc.) and your driving environment.  Properly aligned wheels can help your vehicle perform better and save you from expensive repairs down the road.

Hey Duke here and there are some dashboard lights you should pay more attention to than others.  One is the airbag light.  If it's on and your vehicle is in an accident, your airbags probably won't do their job.  So today we will bark about the importance of the AIRBAG Light, it will save your life.  So let's get barkin" on this important subject!

Automakers began installing airbags in the late 1990s since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt with an airbag gives passengers the best chance of surviving a crash and minimizing serious injury.

The airbag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated airbag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off."

Different things cause the airbag light to come on.  Your vehicle may have been in an accident during which, while the airbags didn't inflate, crash sensors were activated.  Some of them may be connected to your vehicle's seat belts.  A technician can reset the airbag if this has happened.

Fuses can also blow, which will cause the airbag light to come on.  Another possible cause? A sensor that tells the vehicle's computer whether or not there is someone riding in the passenger front seat may be malfunctioning. 

Airbags are not for the do-it-yourselfer.  They are sophisticated systems that require specialized training and equipment to diagnose and repair.  If an airbag light is on, take it to a qualified service repair facility.  One more thing: remember that safety experts have designed airbags to work in conjunction with seat belts for maximum protection in accidents.  So always wear your seat belt.  

.....and remember, Safety never takes a day off
