MAHLE Engine Coolant Thermostat Housing O-Ring

The MAHLE engine coolant thermostat housing O-ring is a sealing ring that creates a leak-resistant seal between the thermostat housing and the engine. It helps keep coolant inside the cooling system. This type of part is also called a thermostat seal, thermostat housing seal, or coolant thermostat gasket.

Key Features:

• Designed to seal the thermostat housing joint against coolant leaks
• Made from an elastomer compound intended to resist engine coolant and the heat cycling of the cooling system
• Supplied by MAHLE, a long-established OE-supplier brand for engine and thermal management components
• Helps maintain correct coolant flow and system pressure after a thermostat or housing replacement

Replace the O-ring whenever the thermostat or thermostat housing is removed. Doing so helps prevent coolant seepage, overheating, and loss of cooling system pressure. Choose the child item that matches your application for the correct fit.
