What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or warped housing surfaces
• Improper thermostat sealing at the coolant outlet
• Cooling system service issues caused by a damaged housing
• Fitment problems from a worn original housing on Lexus ES350 and Toyota V6 applications

Installation Notes and Tips

Verify engine code, build location, and position notes before ordering, since several applications vary by production details. Transfer any required thermostat or sealing components from the original assembly if your vehicle uses them, because this housing does not include a gasket, seal, or thermostat. Clean the mating surfaces thoroughly and inspect adjacent cooling system parts for wear before reassembly.

Quality Assurance

Dorman designs this replacement housing to match the fit and durability of the original part and to handle extreme temperature changes in the cooling system. The metal construction supports long service life in demanding Lexus and Toyota engine bay conditions.
