Detailed Description

Motorad CH7036 is an engine coolant thermostat housing manufactured to OE quality standards using proprietary material selected for cooling-system durability. This lower thermostat housing is used on a wide range of Toyota and Lexus applications, including Toyota Camry, Toyota Avalon, Toyota Highlander, Toyota Sienna, Toyota Venza, Toyota RAV4, Lexus ES350, Lexus RX350, and Lexus RX450h. The CH7036 is designed for vehicles that use an engine coolant water outlet with housing, and it is a fitment-specific replacement rather than a universal part. This part cross-references Dorman - OE Solutions 902-5861 and Four Seasons 86036 for the same application.

What It Is Used For

• Replacing a cracked or corroded thermostat housing.
• Restoring a leaking engine coolant water outlet assembly.
• Addressing coolant loss at the lower thermostat housing connection.
• Correcting sealing issues caused by heat cycling and thermal shock.
• Returning proper coolant flow control in the cooling system.
