Fuel Injectors

The last new American vehicles sold in CHICAGO with a carburetor rolled out of the Illinois dealerships in 1990. Since then, all new vehicles here in CHICAGO, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for CHICAGO drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas ... read more

The Thom's Four Wheel Drive Guide to Custom Wheels

If you're interested in customizing the wheels and tires on your vehicle, there are a few things you should know first.Most importantly, the wheels you buy need to fit your vehicle. Not all wheels are created equal. Too many CHICAGO drivers have bought a set of wheels that caught their eye, then, after going to the work of mounting them, have found that the wheels don't fit right and the tires rub against the vehicle when they turn or go over a bump.To ensure a proper fit, you can consult with your Thom's Four Wheel Drive tire professional. He/she can also help you find tires that are suited to your driving habits as well as your vehicle. You may find their auto advice invaluable, and you'll probably be happier with your new wheels once you purchase them.But if you just have to have that set of wheels, and you're willing to pay for them, you can modify your vehicle to fit the wheels. Again, you shoul ... read more

Combustion Choreography: Timing Belt Replacement at Thom's Four Wheel Drive in CHICAGO

Have you ever seen a ballet performance? Have you wondered how all of those dancers manage to travel all over the stage jumping and twirling and never crash into each other? That's the job of a choreographer.Our auto engines are also highly choreographed. Pistons travel up and down inside cylinders. Valves at the tops of the cylinders open to let air and fuel in or exhaust out. These valves have to open and close at precisely the right time or the engine will run poorly if at all. The movement of the valves and pistons must be in harmony with each other. This choreography is the job of the timing belt or timing chain.Timing belts, or chains, rotate the shafts that control the opening and closing of the valves. Timing chains are metal and durable enough that they may never need to be replaced.Most vehicles, however, use a timing belt. Timing belts are tough and flexible, and considering the work they do, they last a long time for CHICAGO auto owners . But they do wear out. If they ... read more

Tire Rotation and Balancing at Thom's Four Wheel Drive in CHICAGO

Tires do a lot of work for CHICAGO drivers. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts while driving around CHICAGO. They also support the entire weight of the vehicle, including you and your passengers. With such important work to do, you want your tires to do their job well. And since replacing tires is fairly pricey, you want them to last as long as possible. There are three keys to long, even tire wear for CHICAGO driving: Proper tire inflation Proper wheel alignment Regular tire rotation and balancing The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That's especially true of front-wheel-drive vehicles whose front tires steer and put the power to the road.SUVs and pic ... read more

Budget for Maintenance in CHICAGO

Sometimes busy CHICAGO residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around Illinois in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time CHICAGO residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's CHICAGO drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's CHICAGO drivers didn't care much for it, either. So on today's vehicles, the fu ... read more

Fuel Saving Tip: Car Weight and Your Illinois Driving

Weight is the enemy of fuel economy. Everyone from CHICAGO knows this makes sense.Some of us in the CHICAGO area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.Guys: sports equipment and tools. Ladies: well, just take a look around the passenger compartment and trunk. I think my car has about 45 pounds of french fries on the floor.All that extra weight wastes gas as you drive between here and there, and everywhere else.Lose the junk and save some money....And you really only need one of those spare tires.

It Is Time to Check Your Intervals

Part of the engineering that goes into designing a vehicle is testing the components to ensure that they meet durability and safety standards. Because of this, manufacturers have a good idea as to how long the parts in your vehicle will last under normal driving conditions. For this reason, they give us guidelines to follow regarding how often to inspect the various parts and systems on our vehicles.Vehicular components are required to meet certain standards. The government mandates some of these standards. Others are set by the auto industry. Recommended car maintenance schedules are designed to help CHICAGO vehicle owners maintain these standards. Disregarding routine maintenance or procrastinating preventive maintenance will result in lowered performance and reduced safety for a vehicle.Maintenance schedules are designed to ensure three areas of automotive performance for CHICAGO drivers: protection of the vehicle itself, efficiency and safety.

Clean Fuel ? Clean Performance for CHICAGO Drivers

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine.CHICAGO auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. CHICA ... read more

Good Timing: Proper Timing Belt Replacement Saves Money for CHICAGO Drivers

Knowing how their engine works can help CHICAGO drivers make informed decisions about auto care and prevent repairs to their vehicles. This is especially true when it comes to timing belts.An engine's power is generated in the cylinders. Inside the cylinder is a piston that moves up and down while the engine is running. Power is generated in a cycle that includes four strokes of the piston. First, the piston drops and a valve at the top of the cylinder opens to let in fuel and air. The piston then rises, which compresses the fuel and air. At this point, the spark plug fires, igniting the fuel and pushing the piston down. This downstroke transfers energy to the engine, which provides the power it needs to run. The piston rises again, and a valve opens to release the exhaust.All of this movement is orchestrated by a timing belt. The timing belt is so named because it keeps the pistons and valves operating in synch with each other, just as a conductor keeps all of t ... read more
