Staying In Charge (Alternator Repair)

Seems like these days, 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.

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 they usually are. 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 the alternator is driven by a belt, the technician will check what shape all the drive belts are in.  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.

Breathe Easier (Cabin Air Filter)

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed.

It's not the same one that filters out the air used in the engine.  The cabin air filter screens out dust and other particulates from the outside air so when it enters the cabin, you don't have to breathe them in when you're driving.  Maybe your commute finds you traveling along dusty rural roads, or maybe you pass by some city factories that have smokestacks spewing out smoky exhausts.  Or in spring, maybe you notice your allergies acting up because of the pollen in the air.  The cabin air filter will remove a lot of those things.

The more it filters out, the more those small particles add up.  That reduces how much airflow the heating/air conditioning system can handle, and you may notice not as much air is coming through your vehicle's vents.  That can also be a sign you need your air filter replaced.

Our technicians will remove and inspect the air filter; it's usually located around the glove compartment, under the dash or sometimes in the engine compartment. If you wish, your service advisor can show you what condition yours is in; if it needs replacing, you'll be able to see the dirt, bugs, leaves and other crud that accumulates after several months of driving. 

Each vehicle's manufacturer recommends an interval after which your cabin air filter should be replaced. Depending on how much and where you drive, you might find yourself needing a replacement more or less often than the manual suggests.

Just like you clean your furnace filters periodically, it's wise to do the same with your vehicle.  After you do, you'll find you might just breathe easier!

Full of Hot Air (Air Conditioning)

In warm weather, you want to be in a cool vehicle. When we're talking cool, we don't mean stylish or trendy, but cool as in not sweltering inside.  And if your vehicle's air conditioner stops working correctly, it seems to always break at the worst time—during a heat wave. 

Automotive air conditioning problems fail for a number of reasons:

• Blower motor not working.  No air comes through the vents, even though the rest of the system could be working fine.
• Refrigerant leak. When the gas that cools the air off escapes from the air conditioning system, your air conditioner can no longer cool off the outside air
• Condenser and compressor. These are parts of your AC system that compress and expand a refrigerant gas to cool off the outside air. They are fairly complex.

When you bring your vehicle into our service center, we'll run a series of diagnostic tests to figure out what isn't working correctly.  The air conditioning system has a lot of parts. There are electrical and mechanical components plus a series of hoses and tubes that all can wear out over time.  Any one of these can fail.

A lot of drivers think they have a "Freon leak" and believe that if they get their AC system recharged with the refrigerant, everything will be fine.  But AC systems are so complex, it usually takes a trained technician to accurately figure out where the problems are.

Sometimes the solution is simple.  If your blower motor wears out or there's a fuse that has blown, the technician can replace the bad parts and you'll quickly be back to enjoying your rolling refrigerator. But when compressors or condensers go bad, those are much more involved and expensive to fix.

For instance, electrical problems can sometimes lead to acid to build up and corrode other parts of your AC system.  Sometimes that causes so much damage, your whole air conditioning system has to be replaced. That's why it's always a good idea to have your AC regularly maintained.  Our technicians can find a problem early and prevent more expensive repairs down the road. That's really the cool way to go.

Oil Times are a-Changin' (Oil Change Synthetic)

When it comes to oil changes, things are really changing.  Most newer vehicles require synthetic oil, and while it costs more than conventional oil, it doesn't need to be changed as often.

When conventional oil was the only game in town, you changed your oil every 3,000 miles/5,000 km. But as technology in newer vehicles has rapidly changed, so has oil technology.  Synthetics have been around since the seventies.  Even though they start with a conventional oil base, they are engineered in a chemical processing plant with properties that allow them to keep your engine lubricated at very high temperatures.  They are more uniform and consistent.

Synthetic oil doesn't break down as easily, so it lasts longer than conventional oil.  And synthetic oil can flow more easily, even in extremely low temperatures.  As you can see, it has performance advantages at both temperature extremes.

Generally, in recent years automakers have been shipping most of their vehicles with either synthetic oil or a synthetic blend.  Blends are cheaper and have many of the advantages of synthetics.  Another reason synthetic oil is being used in many newer vehicles is its ability to flow more easily improves efficiency.   

It's important to follow your vehicle manufacturer's recommendations when you have your oil changed, so our service adviser can see what options you have for your vehicle. Many newer vehicles come with specific recommendations for synthetic oil. If you live in an area with wide temperature extremes or do a lot of stop-and-go driving, synthetic oil can offer advantages. 

Older vehicles can do fine with conventional oil, but it will have to be changed more than synthetic oil. Also, if you have an older vehicle with more than 75,000 miles/120,000 km on it, it can be more prone to leak and burn oil. Some synthetic oils are designed to protect those high-mileage vehicles better than conventional oil, and yours may benefit. See what your service adviser thinks.

A Head Start on Starting (Battery Testing)

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery.

It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery. 

Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician will see if there's a bad cell in the battery or if it can be recharged.  We will also look at the date it was made. 

At the same time, the technician will look at the whole charging system, including the alternator, starter, cables, and connections.  From there, the service advisor can go through your options. 

Your best chance of not getting stranded by a dead battery is to have your system checked as part of a regular maintenance plan.  That should give you a head start on dependable starts.

Shifty Letters PRNDL (Transmission)

You probably figured out those shifty letters.  They're what you see on your automatic transmission shifter and stand for Park, Reverse, Neutral, Drive and Low.  Your automatic transmission is one of the great automotive inventions; here are some ways you can keep yours working well.

Maintain your transmission regularly.  A technician will check your transmission fluid's level and even its appearance and smell.  If it's dark or has an unusual odor, that could be a sign of trouble.

Change from one transmission direction gear into another only when your vehicle is stopped.  So many drivers want to switch from Reverse to Drive quickly or the other way around.  If you do that when the vehicle is moving, you can damage your automatic transmission.

Keep your vehicle's cooling system in top shape.  What does the cooling system have to do with the transmission? It helps keep the transmission fluid from overheating. 

Follow the manufacturer's recommendations for maintaining your transmission.  Some recommend at least an annual checkup by a trained technician. 

Let your powertrain warm up a little before overtaxing it. Especially in cold weather, don't step on the throttle too aggressively before all components are warmed up.  That way both your engine and transmission will last longer.

Transmissions can be costly to fix.  If you treat your powertrain with respect and regularly maintain it, you'll not only avoid expensive repairs, but you’re also much less likely to find yourself stranded because of a transmission problem.

Keeping Your Cool (Coolant System)

No matter what the weather is like outside, your internal combustion engine expects to keep its cool all the time, even when it's really cold.  That's because engines create the power that moves you to your destination by a series of tiny explosions of a fuel and air mixture. In turn, that generates a lot of heat in a small space.

Your vehicle has a complete cooling system with a lot of different parts that work together to keep the temperature at a point where the metal engine parts won't heat up enough to warp.  Its lifeblood is coolant, a liquid that circulates through the engine (and, in most vehicles, the transmission, too) through a series of hoses and tubes. 

In order to get rid of the coolant's heat, your vehicle has a part you probably recognize: the radiator.  It does what its name proclaims: radiates heat.  The radiator has a series of thin metal fins that coolant goes through, and when outside air passes over them, the heat is dissipated from the radiator into the air.

The water pump (which is technically a coolant pump) is what propels the coolant where it needs to go. 

When there's a problem in the coolant system, it may because it's leaking somewhere.  A few things to look out for are the temperature gauge heading into the hot, or red, zone, fluid leaks under your vehicle, or the sweet smell of coolant under your vehicle after it's been parked.

If your vehicle has any of those signs, bring it in so we can check things out.  A technician will inspect the water pump and hoses for any signs of leaks.  They'll also look for leaks or holes in the radiator core or cores. 

One other potential trouble spot is the radiator cap that can sometimes fail to keep the required pressure in the radiator.  Once the problems are fixed, they'll add the correct coolant and you'll be on your way.  We want you to always keep your cool.

A Clean Start (Battery Cleaning)

Your vehicle is loaded with electrical devices. Computerized components are everywhere, so good electrical connections are important.  Those begin with your vehicle's battery, so it's important that its connections are in top shape.

Ever had a flashlight that didn't work, took out the old batteries to replace them and noticed the old batteries were all corroded? The same thing can happen to your vehicle's battery. 

The battery type used in most vehicles is a lead-acid, which can be very corrosive.  Corrosion can build up around your battery's terminals that can prevent the electrical connection from being as solid as it needs to be.  You may have even seen discoloration around your battery's terminals if you look under the hood, a sign of corrosion.

Or you might notice visible signs of fraying or loose battery cables. All of your vehicle's components are affected by vibrations from the engine and road surface imperfections, and the battery cables take a lot of jostling every time you drive.  Frayed cables won't conduct as much electricity as intact ones.  Plus, there's the possibility that a frayed cable may touch a piece of metal in the engine compartment that can cause shorts and other problems.

There are some signs to watch out for that might tell you if your battery terminals are corroded or your cables aren't making good contact with them.  You might find your vehicle isn't starting as easily as it used to. You also might see the battery warning light illuminated on your dash. That light looks like a rectangle with a "-" and "+" sign inside.

Our technicians can make sure your battery and cables are at optimal operating capability with regular service and cleaning.  A technician will clean the terminals and portions of the cables that are connected to them.  They may also add an anti-corrosion agent to the cables/terminals. Nothing like giving your vehicle a clean start!

To Fix or Not To Fix (Tire Repair)

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it.

With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision. 

One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire. 

If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall doesn't have the reinforcements that the tread area does.  In fact, any puncture that's more than a ½ inch/12 mm away from the edge of the tread should not be fixed. 

Many newer vehicles have no spare tires (to save weight and fuel) and instead have a type of tire called "run-flat."  Sometimes, the only way you know they're deflated is when the tire pressure monitor alerts the driver.  Driving on them more than 50 miles/80km can render them un-repairable.  They may be fixable if you pulled off to the side of the road before driving on them too long. Our technicians can evaluate whether they can be driven further or should be replaced.

Other vehicles with no spare include a can of tire sealant and a compressor.  If you use it, tire experts say to have the tire professionally repaired as soon as possible.

If you have had a flat tire, try not to drive on it unless it's necessary to get your vehicle away from a dangerous situation.  Our technicians can evaluate any tire you may be having problems with and recommend whether repair or replacement is the best option. Your safety is riding on your tires.

Your Vehicle's Hissy Fit (AC System)

When you hear hissing sounds coming from your vehicle, you might start thinking the worst.   One type of hissing coming from around your air conditioner may be a normal sound, or it could be a sign of serious trouble.

First - the normal sound.  When you turn off your vehicle, the refrigerant goes from its high-pressure side to the low-pressure side. Some of those noises are normal.  But when it hisses all the time, that's another story.

One cause could be that the refrigerant is leaking.  Air conditioners are fairly complex systems that involve various pumps, hoses, valves and motors.  When your air conditioner is cooling, the refrigerant changes from a gas to a liquid and back.  That refrigerant is under pressure, and there are many places it can leak from. 

A hissing sound can also be a failed valve in your air conditioner's compressor.  It is what controls the refrigerant's pressurization.  It's important to have this fixed fairly quickly after it develops a problem because when it isn't, that can lead to more extensive—and expensive—repairs.

If you hear screeching coming from your air conditioner at the same time you hear hissing, your compressor may be on its last legs. It could also be a defective clutch. 

Any time you hear a noise you haven't routinely heard before, bring your vehicle to us so a technician can check the various components and properly repair the problems.  Air conditioning systems are complex and are best handled by a professional with the right tools and equipment.  When your AC has a hissy fit, let us cool it off and you at the same time.
