Seal the thermostat housing and keep coolant contained with the MAHLE Engine Coolant Thermostat Gasket C31646. It drops in as a direct-fit replacement for a wide range of Chrysler-family applications, from the 1992-1994 Plymouth Colt to the 2001-2010 Chrysler PT Cruiser, restoring a clean seal between the thermostat housing and the engine.
This gasket sits at the coolant passage where the thermostat mounts, sealing the joint so coolant flows through the intended path without seeping past the housing. If a hardened, cracked, or leaking original gasket is the cause of a weep at the thermostat housing, this replaces it.
Replace the gasket whenever the thermostat housing is opened for service to help ensure a fresh, reliable seal.
