Belts | All Mopar Parts

Cars often have timing and fan or serpentine belts incorporated into the engine assembly. The serpentine belt moves through the engine and helps power the alternator, air conditioning system, and other components. The timing belt synchronizes the camshaft and crankshaft to ensure the proper opening intervals of various valves in the engine.

How many belts are in a car?

Most vehicles can use one to three belts, depending on their make and model. Serpentine belts are the most common type seen in modern cars, while others also use timing and V-belts. V-belts are more common in older cars. This assembly consists of multiple belts to run the crankshaft, water pump, power steering pump, and other engine components.

Do all cars have timing belts?

Some vehicles utilize a timing chain instead of conventional timing belts. Both have the same function and instead differ in construction. While timing belts go below a timing cover near the front of your engine, timing chains are inside the engine casing and require proper lubrication to stay intact and work efficiently.

Can you drive a car without a serpentine belt?

You can’t drive your vehicle without a working serpentine belt since your coolant won’t flow into the engine to maintain its temperature properly. This can result in overheating and other engine issues such as piston, gear, crankshaft, and valve wear due to inconsistent internal pressure. Additionally, a failing serpentine belt can lessen the power of your steering system.

Why is my car belt squealing?

The squealing sound from your engine can be caused by the vehicle belt slipping on the metal pulley. The slippage can stem from incorrect tension or natural wear and tear. If your car belt has worn with age, it may have a glazed, cracked, or brittle surface. The belt can also become brittle over time due to debris and heat from your engine.
