Detailed Description

The Motorad CH6139 thermostat housing is engineered as an OE-quality replacement for cooling-system repairs that require dependable sealing and accurate coolant routing. Its aluminum construction helps provide stable performance in high-temperature environments, while the leak-tested design supports a secure installation. This part cross-references Dorman - OE Solutions 902-5035 and Focus Auto Parts 86139 for the same application. The CH6139 is a practical choice for Toyota Corolla, Toyota Matrix, and Toyota Celica cooling-system service, as well as Pontiac Vibe applications listed in the fitment data.

Common Issues It May Solve

• Coolant leakage at the thermostat housing.
• Cracked or warped original housing.
• Improper sealing at the coolant outlet connection.
• Cooling-system service needs on aging plastic or worn housings.
• Fitment-related replacement needs for the listed Toyota and Pontiac applications.

Installation Notes and Tips

Verify the outlet port diameter, mounting hole count, and application notes before installation. The fitment data includes Toyota Corolla, Toyota Matrix, and Toyota Celica listings with engine coolant water outlet with housing notes, so confirm the existing configuration matches the vehicle requirement. Replace the gasket or seal if the service procedure calls for one, since this housing is listed without a gasket or seal included.

Motorad manufactures this housing to OEM quality standards as an OE supplier. The CH6139 is thermal shock validated, 100% leak tested, and built to meet or exceed OEM standards.
