The Thermostat resides between the engine and the radiator, regulating engine temperature. When the engine is cold, the valve of the thermostat is held shut to prevent coolant into the radiator. When the engine heats up, the valve opens so that coolant can circulate through the engine and cool the system. When a car overheats, it could be the result of a faulty thermostat.
Tire Diameter is determined by the width, ratio, radial and rim. The measurements can be found stamped on every tire.
Tire Rotation is the act of moving the tires on the car from one position to another in order to extend the life of the tires by helping them wear more evenly.
Tune Up refers to service and maintenance on your car. In the past, cars literally needed "tuning" to recalibrate settings. Newer cars of today have different systems, some that self adjust. Despite all that, you car’s oil still needs to be changed regularly, fluids need to be topped off, brakes need to be inspected, and tires need to be rotated. There are also many hoses and belts that should be regularly examined for wear to prevent more serious maintenance issues.
Torque is a measure of how much force on an object causes that object to rotate, and is often expressed in “pounds of power.” In simpler terms, torque determines how fast a car can accelerate. For example, you’ll hear a manufacturer boast, “This car can go from 0 to 60 mph in 4 seconds.”
When the road is wet, Traction Control helps limit tire slip when you’re accelerating from a stop, so that you’re wheels don’t peel out or cause you to lose control.
A Transaxle combines the transmission, differential, and ancillary systems around the axle into one integrated assembly. You will usually find transaxle configurations in cars where the engine is placed at the same end of the car as the drive wheels. For instance, when you have a front-engine, front-wheel drive configuration, or a rear-engine, rear-wheel drive configuration, the design will use a transaxle.
The Transmission transfers the output of the engine to the drive wheels of the car. Your car’s transmission is usually connected to the crankshaft via a flywheel and/or clutch. The engine’s power is transmitted from the driveshaft to the differentials, which causes the wheels on the axle to rotate.
Transmission Fluid is highly specialized oil designed for use in automatic transmissions. This fluid assists proper valve operation, reduces brake band friction, and lubricates the torque converter and gears.
Tail Lights are mounted to the rear of the car above the bumper. They are red in color and have accompanying white lights beside them to indicate when the vehicle is in reverse. When you’re on the road, tail lights make other car’s aware of your presence so that you can travel safely in the dark. Also, the red color of the tail lights shines more brightly whenever you are braking so that other cars know to slow down as well.
The Tail Pipe is part of your car’s exhaust system. Like a chimney on a house, it is designed to release exhaust away from the vehicle and into the air. Exhaust pipes connect to the muffler and are often attached to the rear end of the car with a bracket. Exhaust pipes are susceptible to damage from rear end collisions, failed brackets, broken seals, and corrosion from age.
The Throttle System regulates the amount of air entering the engine, indirectly controlling the fuel-air mixture needed for engine power. When you press your foot on the accelerator lightly, the throttle valve opens slightly to let in a small amount of air. Conversely, if you “floor it” and press down hard on the gas pedal, the throttle opens wide to let in more air, signaling to the car you want to go fast.
Your car’s Timing Belt controls the camshaft, which opens and closes the intake and exhaust valves of the car. While timing belts have a pretty long life span, they will eventually wear out. This will cause the engine to fail.
The Timing Belt Tensioner maintains the proper tension on the timing belt. Timing belt failures are usually a result of a worn timing belt tensioner.
