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.

Automotive Tips from A.G. Automotive & Diagnosis: Making Your A/C System Last Longer

Winnetka drivers know that if their air conditioning system isn’t making cool air like it used to, there is a problem. It may be as simple as adding more of the right kind of refrigerant.

Your A/C requires special compressor oil, which circulates through the system along with the refrigerant, to lubricate and protect expensive components and keep seals and gaskets from drying out. If refrigerant has leaked out – so has the compressor oil. This oil needs to be replenished whenever refrigerant is added.

An air conditioning inspection at A.G. Automotive & Diagnosis will uncover any potential problems and identify any necessary repairs needed to get Winnetka drivers on the road to cool air once again.

Give us a call.

I Had No Idea! (Four Things You Didn't Know About Vehicles)

Bet you didn't know:

Some of the earliest rearview mirrors were marketed as "Cop Spotters" so drivers would know when police were following them. Who wants a ticket, anyway? According to eBay Motors, Elmer Berger first patented a rearview mirror that was mounted on the front fenders, on the spare tire secured to the side of the car of at the top of the driver's door frame. 

About 80 percent of your vehicle is recyclable. So says The Balance. That means four-fifths of most vehicles can be recycled.  Much of that recycling is done by automotive aftermarket recyclers.  Between the U.S and Canada, they reclaim enough steel to produce 13 million new vehicles.

The man who invented the first modern cruise control couldn't even drive a car because he was blind! His name, says Smithsonian.com, was Ralph Teetor.  Blinded at a young age by a knife accident, Teetor was inspired to create a speed control by a couple of things.  One, the U.S. imposed a mandatory 35 mph/55 kph during World War II to conserve fuel and tire rubber, and Teetor wanted drivers to go a safe and steady speed.  Plus, a chauffeur who drove him around used to randomly slow down and speed up which irritated Teetor.  So he invented a speed control to encourage drivers to drive at a more constant and safer speed.

The first grooved tires were invented in 1904 by Continental.  But that was a big improvement over the very first "tires" which were actually metal hoops that made riding in the first cars a pretty rough experience.  The first rubber tires were solid rubber, not inflatable like today's tires.  Things have come a long way.  Modern tires are made with sophisticated rubber compounds that can deal with heat and cold.  Plus their tread patterns help drivers get better traction on wet roads when it storms.  Still, it's important to make sure yours have enough tread and are properly inflated for maximum safety and performance.

Quite frankly, there's a lot we don't understand about the vehicles we drive.  They're much more complicated than the old horse and buggy that preceded  them.  Leave your vehicle's maintenance and service to highly trained technicians who DO understand how to maintain, diagnose and repair today's modern, sophisticated vehicles.

When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing Winnetka drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in Winnetka to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.

If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspension system. Struts are a compact combination of springs and shocks. They do the same job but in a single package.

Shocks wear out gradually, so it can be difficult for Winnetka drivers to notice when they need to be replaced. There's no definitive point when a vehicle's ride goes from "smooth and controlled" to "a bit imprecise." To check if your shocks or struts are worn, you should first do a visual inspection on them. If they are leaking fluid, they need to be replaced.

There are other less obvious signs that your suspension system needs attention. For example, an uneven, cupping wear on your tires may indicate that your shocks are worn. If your vehicle feels “floaty” when you turn, or, in other words, you don't feel that you have full control of the vehicle, you should check your shocks. Also, if the front end of your vehicle dips noticeably when you stop, it's time for new shocks.

Your owner's manual gives recommendations on how often the shocks should be checked, usually between 15,000 and 30,000 miles (24,000-50,000 km). If one of your shocks does need to be replaced, you should replace all four. This will keep your suspension even and ensure good handling of your vehicle. If you carry heavy loads, tow a trailer or drive on uneven Winnetka area terrain, you might also consider upgrading to a heavy-duty shock.

Regular shocks contain hydraulic fluid. The fluid helps them absorb the bumps or “shocks” of the road so the impact doesn't transfer to the vehicle's body. Premium shocks are filled with compressed nitrogen gas, which costs more but does a better job of controlling body motions. Regular shocks can develop air bubbles that reduce their effectiveness; the premium shocks don't have this problem. So if you want higher handling performance, if you drive off-road around CA or if you just want added comfort, you should consider upgrading to premium shocks or struts.

Replacing struts can put your vehicle out of alignment, so an alignment check should always follow this type of repair. Talk to your service advisor at A.G. Automotive & Diagnosis in Winnetka for more information.

Greeted by a Screech (Loud Noise when Starting Vehicle)

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be.

The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix.

Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts and some pulleys contain rubber that dampens engine vibrations.  The rubber in the pulleys can crack or deform with age, which prevents them from working correctly and may cause your belts to wear out.

A technician will check to see if the belts are worn or cracked.  He or she will also check the tension on the belts, the condition of the pulleys and whether all  components are aligned the way they should be.

Sometimes, the noise is nothing major to worry about, but it's still worthwhile to rule out any problems that have cropped up now or may appear in the future.  You'll have a properly running vehicle that sounds like its engineers intended… quiet and smooth.

Lean Times (Shocks and Springs)

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem.

Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces.

If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, eventually resulting in a failure.  The metal can get so fatigued that it breaks.  Often when one side of a vehicle is too high or too low, your service advisor will advise you to have the other side done as well.  That's because if only one side has new parts installed, it won't be level with the side that has old parts. 

There are a couple of other reasons vehicles can lean.  One is that the suspension can be bent or the chassis twisted, again due to wear and tear by driving on rough roads, over badly maintained railroad tracks or in deep potholes. 

Another reason your vehicle may lean is that the tires and/or wheels aren't all the same size.  Or one side might have drastically over or underinflated tires.  This can be a dangerous condition since the imbalance can affect steering and handling.

Considering what drivers put suspension parts, tires and wheels through, it's not surprising that they can be punished so much that they don't hold up like we want them to.  A level-headed driver will make sure to be driving a level vehicle by making sure these components are maintained in good condition.
