What is a gasket on a car?

A gasket is a mechanical seal that fills the space between two or more mating surfaces to prevent fluid or gas leakage. In cars, gaskets are typically made of materials such as rubber, silicone, metal, or paper, depending on the application.

The main function of a gasket on a car is to create a tight seal between components such as the engine block and cylinder head, exhaust manifold, oil pan, or intake manifold. This helps to keep fluids from leaking out of the engine, prevents the mixing of oil and coolant, and ensures proper compression and combustion in the engine cylinders.

Gaskets are crucial components in a car's engine and other systems, as they help maintain the integrity of the sealed components and prevent costly leaks and damage. Over time, gaskets can wear out, become brittle, or develop leaks due to heat, pressure, and chemical exposure. It is important to regularly inspect and replace gaskets as needed to keep your car running smoothly and efficiently.
