Detailed Description

Fel-Pro 35615 is an engine coolant thermostat seal engineered for sealing the thermostat housing in cooling system repairs. Fel-Pro focuses on vehicle-specific sealing solutions, and this premium seal is built to match the demands of the application rather than using a generic one-size-fits-all design.
