MAHLE Engine Coolant Outlet O-Ring

The MAHLE Engine Coolant Outlet O-Ring is a replacement sealing ring (also called a coolant outlet seal, thermostat housing O-ring or water outlet gasket) that seals the joint where coolant leaves the engine. It helps keep coolant inside the cooling system and prevents external leaks.

Key Features:

• Seals the engine coolant outlet connection to prevent coolant seepage
• Made by MAHLE, an original equipment supplier to many automotive manufacturers
• Elastomer construction designed to handle engine heat, coolant exposure and pressure cycling
• Built to fit and seal like the original part
• Useful when replacing a thermostat, coolant outlet or water outlet housing

Replacing the O-ring whenever the coolant outlet is removed helps restore a leak-free seal and protects the cooling system. It also helps the engine hold proper operating temperature.
