Detailed Product Overview

  • Temperature fluctuation during stop-and-go driving
  • Cooling system service on vehicles calling for an 82°C thermostat
  • Replacement of a worn or sticking thermostat

Installation Notes and Tips

Verify the thermostat opening temperature and flange dimensions before installation. Because the gasket or seal is not included, reuse should not be assumed; inspect the sealing surfaces carefully and replace any worn coolant system components as needed. Confirm the housing style and valve orientation match the original part, especially on applications using an off-set valve seat.
