Detailed Description

This engine coolant thermostat housing is engineered for direct replacement use on select Toyota Camry, Toyota Solara, Toyota RAV4, and Toyota Celica models. The Dorman 902-5000 housing is shaped to match the stock part’s fitment and cooling-system connection points, helping maintain proper coolant routing at the thermostat location. This part cross-references Gates CO34789 for the same application.

Compatible With 1993-2001 Toyota Camry, N/A; 1999-2001 Toyota Solara, N/A; 1996-2000 Toyota RAV4, N/A; and 1992-1999 Toyota Celica, N/A. The Dorman 902-5000 is a practical replacement when the original housing is cracked, warped, or no longer sealing correctly.

What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or heat-damaged plastic housing
• Poor sealing at the thermostat mounting area
• Cooling system service issues caused by a worn housing
• Fitment problems from an incorrect replacement housing

Installation Notes and Tips

Verify the outlet port diameter, neck angle, and mounting-hole layout before installation. Clean the mating surfaces thoroughly and inspect the gasket surface for debris or old seal material. Transfer any required thermostat-related components from the original setup, since the thermostat is not included.

Quality Assurance

Dorman designs this replacement housing to match stock fit and durability requirements for the listed Toyota applications and to withstand extreme temperature changes for extended service life.
