Busted! Air Conditioning (Air Conditioning Maintenance)

Your vehicle's air conditioning is something you count on when the weather heats up.  But there's bound to be a day when you turn it on and one of these things happens:

• Only warm air blows out
• Cold air starts blowing out but then it turns warm on its own
• It's not blowing air at all
• It blows smelly air out

Some people are tempted to try to make the diagnosis—and the repair—on their own.  They think it's just run out of refrigerant and they can pick up a can at a local auto parts store and re-charge it.   If only it was that easy.

A vehicle's air conditioning system is complex and made up of many parts.  A compressor, evaporator, condenser, tubing, hoses, sensors, valves… the list goes on and on.

Each of these components could be the reason for the problem.  It could be a leak that's letting the refrigerant escape, but simply re-charging the system hasn't fixed the problem. You have to find the source of the leak and fix it. Service facilities have a device called a "sniffer" which can sniff out refrigerant chemicals. And they can use black light to locate refrigerant that has an ultraviolet dye in it. 

But often other components wear out; blower motors go bad, resistors blow, tubes clog, compressors fail. And diagnosing that takes training and special equipment you'll find at your service facility.

One other thing to keep in mind.  It's always better to catch any problems in the air conditioning system before it fails. Ask your service advisor about having

the A/C checked as part of the vehicle's maintenance.  That's the cool way to go.

Improve Your Night Vision When Driving in Charleston

Night driving in Charleston is not as safe as daylight driving as evidenced by the increased accident rate at night. Much of that is simply because it's dark outside.

Visibility is important to safe driving. Ninety percent of our driving decisions are based on what we see. And at night, we just can't see as much as we can during the day. In fact, if you have 20/20 vision during the day, your night vision is only 20/50. To translate, that means that an object you can clearly see 50 feet away during daylight, only becomes visible to you at 20 feet at night.

Reaction time is also related to visibility. Charleston motorists don't react to a situation until they see it. So at night, we're reacting to situations later just because it takes longer to see them. But we don't have to stop driving at night to stay safe. We just need to practice some preventive maintenance and vehicle care that will maximize our night vision.

The most crucial item that helps us see while driving at night is, of course, our headlamps. Charleston drivers should ensure that their headlamps are as bright as they can be. Headlamps dim over time, but they do it so gradually that it's difficult to notice. Because of this, experts recommend replacing headlamps once a year.

That's good auto advice for Charleston drivers, but it doesn't apply to all headlamps. Some vehicles use HID, or high-intensity discharge, headlamps. These are bright headlamps that are designed to last for the entire life of a vehicle. Depending on your vehicle, you may be able to upgrade to HID headlamps. Consult with your friendly service advisor at Steve & Stacy's Servicenter to learn your options.

Most vehicles use standard or halogen headlamps. If you use standard headlamps, you might want to upgrade to halogen, which offers a brighter headlight. Halogen headlamps come in a variety of grades, so evaluate your options the next time you replace your headlamps and upgrade if you want a better light.

It won't do much good to upgrade or replace your headlamps, however, if your headlight lens is dirty or yellowed. Studies have shown that about 90% of the vehicles on the road have impaired headlights due to dirty or yellowed headlight covers. You should get into the habit of washing your headlights every time you gas up. Simply grab the window washer squeegee, run it over your windows, then swish it across your covers. No cost involved at all.

Plastic headlamp lenses yellow or become hazy over time. If your lenses have this problem, they can be restored with a special polishing process. You may be able to get this done at your Charleston service center. If not, they should be able to tell you where you can.

Now, what good is a quality headlamp if you can't see through your windshield? Your windshield needs to be clean and streak-free if you plan on driving at night in Charleston. You should also keep your windshield washer fluid replenished and your wipers in good condition.

Wiper blades should actually be replaced twice a year. The changing of the seasons at spring and fall, or Daylight Saving Time, can be a good reminder to do this. And while you're at it, fall is the perfect time to replace your headlamps. Those long winter nights add up to a lot more night driving for people in Charleston.

Stay alert. Stay awake. And keep those headlamps burning bright.

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our Steve & Stacy's Servicenter technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.

Cool Running (Water Pump)

Your vehicle is like you in a way.  When it gets hot, it needs to be cooled down.  And one of the key parts to keeping it cool is the water pump.

Now, that's a bit of a misnomer.  It IS a pump, but it's pumping coolant, not pure water.  Cooling off your engine is vital since it builds up heat when it creates power by burning fuel.  Your water pump acts as a way to recirculate that coolant.  It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat.  Cooled off, the coolant is recycled through the water pump to start the journey again.

The water pump works by taking mechanical power from the engine, usually from a belt.  Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job.

Here are some things to look for that will signal problems with your water pump.  If your heat gauge is erratic or showing a much higher than normal temperature, that could be a sign of trouble.  Another is if you hear a whine under the hood.  And if that gets louder when you go faster, get it checked right away.  You may see steam coming out from under the hood or coolant may be leaking. 

These signs signal that it's time for you to have a technician check to see where the problem is. Some water pumps are powered by a timing belt.  If your vehicle has that design and your timing belt is due for replacement, sometimes it's a good idea to replace the water pump too, even if it's working properly.  That's because the labor to replace the timing belt can be expensive and it may be wise to proactively take care of the water pump while it's disassembled.

Your service advisor will explain the options available and offer the best path to keeping your water pump doing its job.  Your engine's life depends on it.

Growing Old Together (Maintaining an Older Vehicle)

More and more of us are hanging on to our vehicles longer.  A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years.  Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles). 

In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it's around 15.  Vehicles are lasting longer these days, and there are several reasons for that.

One expert cites better technology and overall quality improvements.  While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber.  They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy.

Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficient with better performance.  Those factors also contribute to a longer-lasting powertrain.  In fact, it's not unusual to see a powertrain easily last 150,000 miles/250,000 kilometers or more with no major failures.

Drivers are also taking their vehicles in more regularly for periodic maintenance.  Choosing one service facility for all your maintenance can contribute to your vehicle's longevity, too, since technicians know your vehicle's repair and service history.

If you bought your vehicle taking out a 5-year loan and you keep it 11 years, you've managed 6 of those years without a payment, always a nice feeling.  Plus, a bonus is that you get very familiar with every aspect of that vehicle's sounds, smells, handling, stopping characteristics, visibility and limitations.  And the more familiar you are with your vehicle, the more confident you can be as a driver.
