• Replacement of a worn thermostat during overheating diagnosis

Installation Notes and Tips

Verify the 180°F / 82°C opening temperature before installation and confirm housing dimensions against the original part. Because no gasket or seal is included, reuse only if the existing seal is serviceable or install the correct separate sealing component for the application. Inspect the thermostat housing, coolant passages, and mating surfaces for corrosion or debris before reassembly. After installation, refill and bleed the cooling system according to the vehicle service procedure.

Quality Assurance

Calorstat TH6295.82 is specified as a standard replacement thermostat with application coverage that includes OEM-recommended fitments on select Toyota, Lexus, Scion, and Mitsubishi vehicles. Confirm vehicle-specific requirements by year, make, model, and cooling system specification before ordering.
