Water Pump Gasket: The Basics Water Pump Gasket: The Basics

The water pump gasket is a small, but essential part of an automobile's engine system. Below is some basic information about the gasket's composition, what it does for the engine, and what can happen should it malfunction.

The Composition of a Gasket

The water pump gasket is a simple sheet comprised of gasket paper, rubber, silicone, metal, felt, and fiberglass or plastic polymer. It fills the gap between the engine and the water pump in your vehicle.

Preventative Functions

Without the gasket, the coolant flowing between the water pump and the engine block would undoubtedly leak out. This could lead to overheating of the engine and put strain on the components of the cooling system.

What Occurs When it Malfunctions

If the water pump gasket fails, the seal keeping the coolant flowing around the engine and through the radiator will not function. A visible symptom of a failing water gasket is a pool of water underneath your car. Additionally, corrosion and age can cause the gasket to fail which can lead to engine overheating or water in the oil compartment.
