What It Helps Address

• Engine running too cool or too warm
• Delayed coolant temperature regulation after startup
• Temperature fluctuation caused by a worn thermostat
• Cooling system performance issues tied to thermostat sticking
• Replacement needs for a 180F OEM engine coolant thermostat

Installation Notes and Tips

Verify the thermostat temperature rating, flange dimensions, and housing style before installation. Because no gasket or seal is included, reuse only if serviceable or replace with the correct sealing component for the application. Clean the thermostat housing mating surfaces thoroughly and follow the vehicle service procedure for coolant refill and air bleeding.

Quality Assurance

Built by Motorad Standard using OEM specifications, this thermostat is produced with materials and processes intended to meet original-equipment cooling system requirements. The copper case and wax element are selected for consistent response to coolant temperature changes in normal service.
