CHICAGO Car Owners Ask: Why Do I Need to Change My Serpentine Belt?

Any CHICAGO driver who understands preventive maintenance knows that “if it ain't broke, don't fix it” is bad auto advice. Replacing a part before it breaks is much less costly for CHICAGO residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle's electrical systems and to charge the battery. Without the alternator, the battery wouldn't last more than a few miles.3. In many CHICAGO residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump ... 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

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

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 th ... read more
