This is a series of rods and/or cables that connect the gearshift lever or gear selector to the transmission.

Shock absorbers are part of your vehicle’s suspension and contribute to your vehicle’s ride quality. They also regulate how much your vehicle moves up and down after going over a bump.

The radiator is the central component of the cooling system. It takes the heat from the engine and coolant and passes it to the surrounding air, which then cools the engine.

The radiator cap maintains a specific pressure in the cooling system so it operates efficiently.

Photochemical smog, commonly referred to simply as smog, is a by-product of the combination of HC and NO X . In the presence of sunlight these two elements form ozone (O 3), nitrogen dioxide, and nitrogen nitrate; all of which

When your engine knocks or pings, it is a sign that the engine is firing at the wrong time. This could be because of bad ignition timing, an incorrect grade of gas, or another ignition or fuel system fault.

The piston fits into the cylinders and is connected to the crankshaft. When a spark plug fires, it ignites the air/fuel mixture in the cylinder, pushing the piston down which then turns the crankshaft. This is how an engine makes

Piston rings fit around the pistons, and prevent combustion energy from being lost around the edges of the piston. They also prevent engine oil from getting into a cylinder.

A special type of polish designed to gently remove scratches and yellowing from plastic items such as convertible top windows and plastic lenses.

Play occurs when there is excessive free movement in your vehicle’s steering system. For instance, if you turn your steering wheel either direction from the center and nothing happens for the first two inches of travel, your steering system has

Power steering is a steering system with a high-pressure pump that boosts the driver’s steering efforts, making it easier to steer with much less effort.

A special type of fluid designed for power steering systems.

The power steering pump pumps power steering fluid to other power steering system components, allowing the driver to steer with minimal effort.

The pressure plate is part of the clutch. It applies pressure evenly to the clutch disc friction area, thus allowing a smooth application of power.

Pushrods are used in engines with overhead valve (OHV) designs. The camshaft in the engine block pushes up on the lifters and then on the pushrods, which then push the rocker arms, which then open the valves.

This is a switch found on many modern automatic transmissions that prevents a vehicle from starting unless the gear selector is in park or neutral.

Also known as the emergency brake. The parking brake is used when parking on an incline to prevent the car from rolling away.

The parking brake cable connects the parking brake pedal or handle to the parking brakes themselves. Top

The parking brake shoes/pads are just like normal brake pads or brake shoes. The only difference is that they work specifically with the parking brakes.

Powertrain Control Module. The PCM is a powerful computer that manages the Engines Ignition, Fuel Injection, and Emission Systems. In some vehicles it may control the operation of the Transmission and Anti-Lock Brake Systems as well.
