Cayenne Is In Charge (Alternator Repair)

cay

Cayenne here, and it seems like we're hearing about more and more electric or hybrid vehicles.  Keep in mind that conventional gasoline internal combustion vehicles have important electrical components, too, and it's important to make sure they're operating at their peak.  So today, we will bark about who's in charge no matter what you drive: electric, hybrid or gas with alternator repair. 

In a vehicle with a gasoline engine, the part that keeps the battery charged is the alternator.  It converts the mechanical energy created by the engine into electrical power.  To do that, a shaft in the alternator has a pulley on one end that's driven by a belt that is turned by the engine.  A series of magnets then spins around coiled wires and it creates alternating current, or electricity. Your vehicle uses that to charge the battery that, in turn, keeps other electrical components in your vehicle working.

Here are a few signs that the alternator isn't doing its job right.  The battery keeps going dead, your instrument panel's battery light is on (it looks like a rectangle with a - and + inside and a couple of "terminals" on top), or your lights are dimmer than usual. You may also have a voltage gauge that shows lower than usual power. If bearings in your alternator are seizing up, you may hear a grinding noise coming from your engine compartment. If you have any of those signs, bring your vehicle to us so we can check your electrical system.

A technician will run diagnostics on your alternator, the cables and the battery. Because a belt drives the alternator, the technician will check the shape of all the drive belts.  Plus, we'll see how much electricity the alternator is putting out. 

If your alternator has failed, it can be replaced with a new or a remanufactured one. Speak with your service advisor about which will best suit your needs. Oh, and keep in mind that sometimes other parts may have to be replaced at the same time. For example, if your alternator's bearings froze up, that may have damaged the drive belt, and it may have to be replaced at the same time. 

Today, I leave you with this quote,

Duke's Scoop On How Far We've Come (Newer Vehicle Technology)

duke

Hey, Duke here, and you know, everyday technology is changing, and so is the technology in our vehicles. Automotive design has come a long way since the days of the Model T, especially regarding safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years.

Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops. 

Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If you don't heed the warning, they'll put on the brakes for you. 

Blind spot warning.  We all worry about hitting a car approaching from behind and on either side if we change lanes.  Rearview mirrors cover some blind spots, but they're not foolproof.  Enter the blind spot warning system; it warns you with a noise or a light if a vehicle is in a place you might not be able to see.

Lane departure warning.  We all try to stay in our lane, but sometimes our attention wanders.  If you start to drift out of your lane, new warning systems using cameras and other sophisticated sensors will tell you to get back in your lane.  Some send an audible warning; others use a vibration or warning light. Some will even steer your vehicle back into the lane. 

Rearview camera.  There was a time when trucks and SUVs were involved in horrible accidents because the drivers couldn't see what was behind them as they backed up.  Children and pets were among the tragic victims.  Now, inexpensive rearview cameras are required in the U.S. and Canada, saving lives and providing much more peace of mind for drivers of vehicles with rear visibility issues. 

Ensuring this safety technology is working correctly for these systems to be effective is essential.  Your service facility can check and maintain these systems as the manufacturer recommends.

And for this week, I leave you with this technology quote,

Once a new technology rolls over you, if you're not part of the steamroller, you're part of the road. ~ Stewart Brand

Cayenne Is Getting Bad Vibes (Disc brake rotor problems)

cay

Good day my South Bay Drivers, Cayenne here.  Have you ever met another person or dog, in my case, and they gave you bad vibes?  You know there is something not right about them.  Well, your car can do the same thing, throw off some bad vibes, and that isn't good.  So today, we will bark about disc brake rotors and the bad vibes they could be sending out.  

If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes. 

The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that create friction and stop your vehicle.

Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 “S” sounds: squeaking, squealing, or scraping. The sound is usually the first sign of brake pad wear, which can lead to rotor damage.  Soon, you may notice a pulsating or vibration when you brake. That’s because your once smooth and straight rotor disc is warping from the heat generated by friction. Or it may be due to wear.  Eventually, your brakes will take a longer distance to stop your vehicle, and the rotors can have grooves carved into them.

When you start noticing any of these signs, having them inspected by a trained technician is a good idea.  They will measure the rotor thickness, check wear patterns for grooves and heat discoloration, and see how much of the brake pads remain. They will also check to make sure all brake components are moving freely, check your brake fluid, and look for corrosion.

Most vehicle manufacturers require worn or damaged rotors to be replaced, not resurfaced. It’s all part of a complete brake job, replacing pads, brake hardware, and rotors. It reduces the chance of premature failure.

How often you need your brakes serviced depends on the manufacturer’s recommendations, your driving habits, and your environment.  Your service facility can recommend the best replacement parts based on those factors. 

Regular maintenance and attention are vital for keeping your brakes performing as designed. Remember, your brakes are your vehicle’s most important safety feature.

I leave you with this thought for this week,

"Vibes speak louder than words"

Duke Says "When it Comes to Air Filters, Change is Good (Clogged Air Filter)"

duke

Duke here, and you know some people do not like change, but sometimes change is good even for your car.  Your air filter is one of the items on your car where change is good.  But why you ask, well let's get barkin" and find out. 

Engine air filters may not seem like a big deal, but when they’re clogged up with dirt, dust, and insects, your engine could wind up choking for air and not delivering you the power and performance it was designed to give.

There are actually a couple of air filters in your vehicle.  One filters the air into the cabin (the cabin air filter), and the other filters air into the engine.  That engine filter is the one we’re talking about. After several months and long distances traveled, your engine air filter accumulates the junk it’s preventing from getting into your engine. You may notice your engine misfiring, your acceleration may not be what it used to be, it may make strange noises, and the Check Engine light may come on.

When you notice any of those signs, it’s time to bring in your vehicle to have us figure out what’s going on. We’ll visually inspect your air filter.  Keep in mind that your vehicle’s manufacturer recommends a replacement interval for your make and model.  Typically, many automakers suggest replacing the air filter every 10,000-15,000 miles/16,000-24,000 km.  But if you drive in dirty and dusty areas, you should have it checked more frequently.  Also, if you spend a lot of your driving hours in congested urban areas, stop-and-go driving can tax your engine air filter.

When replacing it, it’s important to get the correct filter. Automakers often offer a variety of engines in the same model, so our technician will ensure you’re getting the one made for your vehicle’s configuration.  Remember that the air filter protects your engine from contaminants, and having one that properly fits is essential with today’s modern, high-tech engines.  

Replacing your engine air filter can help prolong the life of your engine. You’ll both breathe better.

Today, I leave you a quote about change,

"If you don't like the road you're walking, start paving another one".

Cayenne's Good Service at Allied Auto Works Equals Good Fuel Economy in Los Altos

cay

Good day, Cayenne here, and whether we're trying to save money, save gas, or save the environment, most of us Los Altos drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in CA, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?  Today we will bark about what you can do to get the most out of your fuel economy so let's get barkin'.

The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.

Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fuel doesn't burn efficiently. Replacing that faulty sensor can save you 40% at the pump. That's certainly a reason to improve your car care and have the automotive professionals at Allied Auto Works inspect things occasionally.

A faulty oxygen sensor will activate the check engine light. So will a lot of other problems, such as big fuel wasters. Finding out why your light is on and fixing the problem will also improve your fuel economy. Bring your car into Allied Auto Works in Los Altos and we will take care of it for you.

What about tires? Los Altos drivers have all heard that keeping them inflated will improve our gas mileage. True? Yep. It's a 3% savings for that one. And even small drops in tire pressure can start to add up, so a weekly tire check is in order.

Using the correct weight in motor oil is another way to save at Los Altos area gas pumps. It adds up to a 2% savings.

What about that courteous driving? That doesn't cost us anything and doesn't require our Los Altos service center to implement anything. Is it worth the bother?

Again, the answer is yes. Sudden acceleration, such as charging away from stoplights, sudden stops, and quick lane changes, all add up to lowered fuel economy. Taking it easy when you drive on CA roads amounts to a 5% savings around town and a whopping 33% savings on the freeway. Is it worth your time to slow down? How much do you get paid?

Speeding is another way we ding ourselves at the gas pump. We've all heard that it's okay to drive five miles over the speed limit, but that actually hurts our wallets. Eventually, it could add up to more than a speeding ticket. An extra five miles over the speed limit ends up costing us 7% per gallon. Fifteen miles over? 23% No,w there's a reason to slow down.

Another thing Los Altos vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping one hundred pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in CA.

Here is one of my favorite jokes about money,

A business man sees two bums and says, "I'll give a dollar to the one who is laziest."
The first bum says, "Give it to me."
The second bum says, "Put it in my pocket."

Have a great day,

Cayenne

Duke Asks Whats Your Number? (What Tire Numbers Mean)

duke 

Hey Duke here and you've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information.  There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on.  Let's check out this example found on an SUV: P245/70R17 108T.

The first letter, P, means it's intended for passenger vehicles.  If there's no letter, it means it's a metric tire.  If there's an LT at the beginning or end, that means a tire is designed for light trucks.

Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall.  The number that follows in our example, 70, means the height of the tire is 70% of its width.  The letter after that in our example, R, describes the type of tire (on this vehicle, radial).  Following that is the diameter in inches, in our SUV example, 17 inches. 

That next number is all about how much load the tires' sidewalls are designed to take (108 in our example).  The higher the load index, the more weight the sidewalls can take.  The last letter is the tire's speed rating in our example, T.  The further along in the alphabet that letter is, the higher its speed rating.  So now you know what those letters and numbers mean.  But why are they important?

When you are getting ready to replace those tires, those numbers tell you what the original equipment was when your vehicle was new.  Sticking with the same rated tires is always a good idea.  If you don't know what you're doing, trying different-sized tires and wheels can cause real issues when it comes to performance and safety, considering all the computerized systems now found on vehicles.  When in doubt, consult your service advisor when buying new tires.  He or she knows what those tire numbers and letters mean… and a whole lot more.

.....and for today, I leave you with this numbers quote,

A good decision is based on knowledge and not on numbers ~ Plato

Cayenne Answers "Why did my vehicle fail its emissions test?"

cay

Cayenne here, and we all don't like to fail on something, especially on our first try, but it happens.  Your car may have even failed its first attempt on its emissions, and I am sure you want to know why.  So today, we will bark about why your car could have failed on its emissions test. 

We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.  

Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen?

One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go.

Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not be working.  It may be physically damaged, or the steady flow of exhaust gases has fouled the converter. 

You may have a bad oxygen sensor. It’s supposed to measure how much oxygen is in your exhaust.  This can cause the air-fuel mixture to be too rich, resulting in too many hydrocarbons in the exhaust. Your ignition system may also have problems, such as worn-out spark plugs.  Dirty fuel injectors can contribute to excess emissions.

Believe it or not, a dirty engine air filter may be the culprit. If it hasn’t been replaced for a while, your vehicle may be emitting too many hydrocarbons -  something that will cause your vehicle to fail the emissions test.

You can usually avoid a failed emissions test by maintaining your vehicle regularly.  The best way to do that is by bringing it to our trained technicians so your vehicle gets the service it needs, scheduled and non-scheduled.  Plus, you’ll be doing your part to keep our air clean.

Here is my inspirational quote for this week,

Either you run the day, or the day runs you. ~Jim Rohn

Duke Has An Emergency! (Vehicle Emergency items)

duke

Emergency, Emergency!  Hey it's the Duke here and today we are going to bark about emergency items you should have in your vehicle.....besides extra dog bones of course.  So let's get barkin' on this important subject today!

"I never expected it could happen to me." Countless drivers have said that after an emergency, they turn their lives upside down. So before that happens to you, let's think about planning for an emergency with a few things you should keep in your vehicle.

  • Road flares. If you've ever driven by a disabled vehicle sitting at the side of the highway at night, you know how terribly hard it is to see, especially in bad weather like rain.  If you are the one in that broken-down vehicle, you run the risk of being hit by a vehicle whose driver literally may not be able to see you.  The best emergency signal includes one or more road flares.  There's a reason police officers and firefighters carry them in their vehicles.  When you see a series of burning red flares at the side of the road, you know something serious is going on.  These are far more visible at a much longer distance than nearly any other portable signal device.

 

  • Fire extinguisher.  Thousands of vehicles catch fire every year.   Most fires start small but can get out of control. Having a fire extinguisher in your vehicle is vital, and several small ones are designed especially for the job.  Since many different types of vehicle fires can start, make sure the extinguisher you choose will handle every fire, from gasoline to electrical. Some have handy mounting brackets. And keep it up to date!

 

  • Flashlight.  Sure, your cell phone likely has a light in it.  But you will need that phone for communication if there's an emergency. Plus, the light’s just not that bright.  So carry an LED flashlight designed for automotive use.  LEDs produce a lot of light with little power; plus, many of those designed for vehicles include a lantern, which will light up a wider area. It’s vital if you have to read your vehicle's jack instructions or tend to an injured person.

 

  • Drinking water and snacks.  If your vehicle breaks down during bad weather and you may be forced to stay with it for a long time, you'll need food and water to survive until help can arrive.  These are simply the necessities of life, so have a small supply on hand, just in case.

Other things like basic tools, a first aid kit, a space blanket and jumper cables are also good ideas.  Many service repair facilities offer these items for sale, and you can ask your service advisor for suggestions.  While it's fresh in your mind, plan a shopping trip and put together your own emergency kit now.  Sure, you can put it off, but you may find yourself stuck in a difficult situation, saying to yourself, "Only if…"

and for this week, here is your inspirational quote,

Cayenne Has An Oil for All Seasons (Engine Oil Selection)

cay

Hello Los Altos, Cayenne here!  You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may make sense, there's some good news.  Most drivers don't have to, and here's why were barkin about this today.  

Engine oil can be made in different thicknesses.  That thickness is called viscosity, which is how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather. 

While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now, that's what I call a great invention.

In most temperate climates, you don't have to swap out the type of oil you use in your vehicle each season. There are exceptions in extreme climates, but your service advisor can advise you on that.  Your vehicle's owner's manual recommends the proper viscosity oil to use.

Remember that even though you may not have to switch to a different type of oil, you DO have to CHANGE the oil at specific intervals.  That's because oil eventually breaks down and picks up contaminants, and if you have old, dirty oil in your engine, it can cause damaging friction and heat. Regular maintenance at your vehicle service facility will ensure your vehicle runs like a well-oiled machine.

Duke Keeps His Your Cool (Water Pump Replacement)

duke

Duke here, and we are in the winter months here in California, and it is starting to get chilly for us.  No matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected.  Well, cool, anyway. So today we will bark about keeping your vehicle cool even when it's cold outside.  Let's get barkin'!

If your vehicle has a gasoline engine, it's powered by many explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT. There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump.  Technically, it's pumping more than water. It should be called the "coolant" pump since the liquid circulates through the system is a mixture of water and coolant. 

Basically, the water pump keeps this coolant moving through your engine, picking up the engine heat and then is pumped into the radiator, where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that shows the temperature is too high, it could mean a bad water pump. 

They can fail for many reasons. They have bearings that wear out, as does the seal between the pump and the engine. They're often driven by a belt or chain that can go bad.  Corrosion can spell the end of a water pump, too. 

If a technician determines your water pump has failed, it's time to replace it. In addition, other components of the cooling system will be inspected.  The best way to avoid a water pump failure is to maintain your cooling system regularly, which includes draining and flushing the coolant. 

Just like it's important for you to keep your cool, the same goes for your vehicle's engine.

My quote for the end of December 2024,

Sometimes it's better to keep your cool, remain silent and smile
