Your Vehicle's Other Power Plant (Alternator Replacement)

Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant.  But it has another power source that is vital as well: the alternator.

The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation.  Maybe you've started seeing those electrical components behaving in strange ways.  Maybe your power windows are going up and down a little bit more slowly than they used to.  Or perhaps your engine doesn't start as easily or is misfiring.  

Other signs of a failing alternator are headlights that are either brighter or dimmer than usual.  If your battery keeps going dead, it could be that the alternator isn't recharging it.  

The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine.  Sometimes that belt can fail.  If you hear a whining sound, it could mean bearings in the alternator aren't turning as freely as they used to. You could even notice a burning smell.  Oh, and when you see your battery light illuminated on your dash (it looks like a rectangle with a - and + inside), it may be warning you that your alternator is not healthy.

Bring your vehicle in to us for a diagnosis if you notice any of these symptoms.  If your alternator is bad, we can recommend a new or remanufactured one to replace it.  Some new alternators are warranted for life and remanufactured units usually are guaranteed as well.  

It's important to your vehicle's health to have its alternator putting out the right power consistently.  It may not be as well known as the other power plant under the hood, but it's a vital part of helping your vehicle run the way it is designed to.

Why is My Brake Pedal Hard to Push?

When you push on your brake pedal, you should find your vehicle easy to stop.  But at some point, you might notice stopping takes much more pressure on the pedal than it used to.  When it gets to that point it becomes a safety issue, and you should bring your vehicle in so we can track down what’s not working correctly.

Brake pedals that are stiff mean there’s something wrong with one or more components of your entire brake system.  For example, it could be moisture has contaminated your brake fluid, making it harder to push the pedal down.

Many vehicles use hydraulics to amplify your pedal pressure to a force strong enough to stop your vehicle.  Certain problems can develop with your hydraulics, such as a faulty master cylinder, a kink in one of your brake lines, or a failed proportioning valve which regulates pressure to your rear brakes. Vacuum leaks can also make your brake pedal hard to push. Another cause could be a problem with your vehicle’s brake booster or its check valve.

Because your vehicle’s braking system is made up of many different components, one of our technicians will look at several different possible causes in yours.  Your vehicle may not have enough brake fluid in it, so they’ll check the level.  A visual inspection of your hoses, brake lines and vacuum line to the brake booster may turn up the root cause of your issues.   

Because there are many different causes of a hard-to-push brake pedal, solutions may involve one or more different steps.  Keep in mind this is one problem that needs to be fixed for you to drive safely.  That’s why it’s important to have a professional track down the issue, or issues, and take care of the problem(s) so you can be back on the road, safely going and stopping.

Don’t Be Hosed (Radiator Hose Replacement)

If you are like most drivers, you don’t worry too much about what shape your radiator hoses are in.  But they are a vital part of your coolant system, helping carry engine coolant from the hot engine to where it is cooled off in the radiator.  

When the cooling system has a problem, you will likely see your vehicle’s temperature gauge showing you it’s running at a higher temperature than it usually does. Or maybe the low coolant light has come on.  If either of these happens, it’s important that you not drive too long since a hot, running vehicle can suffer expensive damage quickly.

Radiator hoses can be damaged by being subjected to temperature extremes, both hot and cold. In addition to the temperature gauge climbing or low coolant light illuminating, there are other clues that may tell you your vehicle is leaking fluid.  You may notice a green, yellow, brown or purple fluid pooled on the ground around your vehicle.  

At any of these signs, it’s time to bring your vehicle in for service soon.  A technician can inspect hoses for leaks, deformities and other problems, as well as looking for cracks and wear.  They’ll also check the condition of the water pump, since problems with it can be another reason coolant will leak out from under your vehicle.

It is better to periodically have your hoses checked rather than waiting until they fail.  How often you should have yours replaced depends a lot on what vehicle you own, and in what conditions it is driven. Rubber degrades not only by temperature but also by what materials it comes in contact with.  For example, oil leaking on a radiator hose can prematurely cause that hose to fail. Age is another factor.  

We recommend you have one of our technicians inspect your cooling system regularly so you don’t get “hosed” by a failure at an inconvenient time.

Don't Be Shocked (Shock Absorbers)

If you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be.  Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride.  That's because it is equipped with shock absorbers.  They are built to dampen impacts from road irregularities.  But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out.  Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected.

When it comes to braking for example, you may take a longer distance to stop.  That's because shocks help keep your tires in contact with the surface of the road.  If the shocks aren't working properly, the tires won't make contact like they should.  So when you slam on the brakes, your vehicle will take longer to stop.

Consider what worn out shocks are doing to your tires.  Since the bumps aren't being dampened as much, your tires can bounce up and down more.  That can produce a problem of uneven wear called cupping.

And when you start out from a stop, your vehicle may not have the traction it should since the shocks aren't keeping them down on the road as you accelerate.  If you have front wheel drive, you may lose some steering control on acceleration. Obviously, many of these things involve safety concerns.

Pay attention to any deterioration in your vehicle's ride quality.  If your vehicle is starting to bounce up and down and its ride feels bumpier than before, head on over to your vehicle service facility and get your suspension checked out.  Do the same if steering response isn't as good as it used to be.  Notice that your vehicle nose dives when you brake?  Are your tires wearing in an unusual manner? All are signs that your shocks may be on their last legs.

If the last time you replaced your shocks was 50,000 miles/80,000 kilometers ago, a technician should evaluate them.  Don't be "shocked" if it's time for new ones.

Power Steering Service in Du Quoin

Most Du Quoin drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine; a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea for Du Quoin drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owner's manual for the right type - or just ask your friendly and knowledgeable pros at McPherson Automotive in Du Quoin.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so Du Quoin drivers need to replace it from time to time. Many vehicle manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the car maintenance schedule for many of us. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your technician at McPherson Automotive will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some  warning signs of trouble with your power steering: It's harder to turn the wheel, there's erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump quickly.

Other steering components can be bent or damaged from wear or hard knocks: ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear and an off-center steering wheel. An annual alignment check at McPherson Automotive in Du Quoin will reveal bent or damaged steering components.

Most SUV's, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. The team at McPherson Automotive also recommends the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners' manual maintenance schedule. It's usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Du Quoin area, the bearings will need service more often.
