How to Radiate Cool (Radiator Care)

There's nothing that radiates cool like a vehicle radiator that's helping to keep your engine running at the proper temperature.  You don't have to baby it, but you can't simply ignore it, either. 

Let's take a quick dive under the hood to let you know what the radiator is doing.  It takes the heat your engine produces and moves that heat outside.  It's not an easy job and heat is an engine's number one enemy.  Now that you're thinking how nice you want to be to your radiator, we have a couple of ideas how you can take care of it.

The easiest thing is to pay attention to your vehicle's temperature gauge. If it gets in the "too hot" or "not hot enough" range, have it checked out soon.  Make sure your coolant is kept at the correct level and if you see a trend that you have to add coolant more than a couple of times a year, you might have a leak.

Even if there are no obvious problems, every couple of years or so, consider taking your vehicle in for radiator maintenance.  A technician can run a pressure check for leaks and ensure that the thermostat and radiator cap are working correctly.  The technician will check that fans are running like they should so they can move air over the radiator and heat away from the coolant inside.

Ask your service advisor when you should have your radiator flushed and coolant replaced according to the manufacturer's recommended intervals.  In addition to cooling, coolant has corrosion inhibitors which stop working after a while.  Without those corrosion inhibitors, the inside of your radiator can literally start rotting away.  Keep in mind that the coolant level must be kept at manufacturer's specifications since if those corrosion-preventing chemicals aren't touching the metal, they're not preventing corrosion. 

Different vehicles use different coolants, so your service facility will make sure yours is getting the correct one.  Keep your coolant system happy and one day, maybe you can order up a custom license plate, "RAY-D-8."

See the Light (Automatic High Beam Dimmers)

It's happened to all of us.  We're driving down a highway at night and over a crest appears a car with its high beams blazing.  You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision.

Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either.  You know, the one who forgets to turn down their high beams.

Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road.  But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams.  Enter the automatic high-beam dimmer.

The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  While touted as being the biggest advance in night driving safety in 30 years, it didn't work all that well.  But as technology got more advanced, systems improved.

Today's automatic high beam dimmers usually have a camera in the rear view mirror (pointing forward).  When the camera sees lights, software in the system's computer attempts to determine the source of the light, whether it is an oncoming vehicle, taillights, ambient city lights, street lights or the reflection off of a street sign.  It then adjusts the headlights to operate high beams if appropriate or a less-blinding mode if they’re not.

Some automakers are striving to make their headlight systems smarter and safer by developing lamps that can avoid blinding oncoming drivers by means other than simply dimming them. One idea? Splitting the beams so they will block just the portion that shines into the eyes of oncoming drivers.

It's a long way from the Autronic Eye.

Got it Covered! (Timing Cover Maintenance)

You may have heard at one time or another about something called a timing belt or timing chain in your engine.  And you may know that if they fail… well, let's just say that there can be some major engine damage.  So obviously, we want our timing belts and chains to be in tip-top shape.

One part that helps keep them running the way they should is the timing cover.  As you can probably guess, it's something that covers the belt or chain.  The timing cover protects both belts and chains from dirt and road debris.  Timing belts also need to be lubricated so their covers allow them to be lubricated as well.  They have a gasket that insures a good seal for the engine.  If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component.

Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on.  You might also notice a drop in power when you're going uphill.

It's important that your timing cover be in good condition and functioning properly.  Your repair facility will check out that part of your engine to make sure gaskets are in good shape and the cover is doing the job it's meant to do.  Catch that leaking or broken timing cover in time and your engine will thank you for avoiding some serious damage and an expensive repair.

The Daily Grind (Grinding Noise)

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you.  No, really, it is.  So listen to what it's saying and you could avoid a much more costly repair down the road.

A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. 

Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening.

Other causes of grinding while turning can be problems with the suspension in the front.  You may have a failing CV (constant velocity) joint.  It could be your brakes are partially engaging while you are turning.  That metal-on-metal sound is never a sign that things are working just the way they're supposed to.

To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all.  Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared!
