Car Engine Sounds Like Washing Machine

Causes

There are a few potential causes of a car engine sounding like a washing machine. These include:

Loose or damaged engine mounts. These mounts are responsible for holding the engine in place and dampening vibrations. If they become loose or damaged, the engine can move around more, which can cause it to make a washing machine-like noise.
Damaged or worn-out belts. The belts in your car’s engine are responsible for driving various components, such as the alternator and water pump. If a belt becomes damaged or worn out, it can slip or break, which can cause the engine to make a squealing noise that sounds like a washing machine.
Exhaust system problems. The exhaust system is responsible for carrying exhaust gases away from the engine. If there is a hole or leak in the exhaust system, it can cause the engine to make a loud, rattling noise that sounds like a washing machine.
Engine knock. Engine knock is a condition that occurs when the air-fuel mixture in the engine detonates prematurely. This can cause the engine to make a knocking noise that sounds like a washing machine.
