Product Details

The Gates Thermostat Seal is an engine coolant thermostat seal (also called a thermostat gasket or O-ring) that seals the thermostat against its housing. It helps keep coolant inside the cooling system and supports consistent engine operating temperature.

Key Features:

Seals the thermostat to the housing to help prevent coolant leaks
Made by Gates, a long-established supplier of engine cooling and belt drive components
Designed for reliable sealing under repeated heat cycles and exposure to coolant
Suitable for replacement when installing a new thermostat or servicing the cooling system

Replacing the seal whenever the thermostat is serviced helps keep the joint tight and the cooling system working as intended. Select the part number that matches your application.
