  • Coolant flow irregularities caused by a worn housing or thermostat assembly
  • Leaks at the thermostat housing seal area
  • Delayed thermostat response during temperature changes
  • Cooling system service needs on listed Honda Accord and Honda Prelude models

Installation Notes

Verify the 180°F temperature specification and match the housing to the vehicle application before installation. Inspect the mating surfaces and coolant passages for corrosion or debris, and replace the seal if the existing sealing surface is compromised. Follow the vehicle service procedure for coolant refill and air bleeding after installation.
