Detailed Description

This Dorman thermostat housing is engineered as a direct replacement for the stock engine coolant thermostat housing used on 1975-1979 Toyota Corona, 1977-1979 Toyota Celica, and 1977-1979 Toyota Pickup models.

What It Helps Solve

  • Corrosion on aging cooling system components
  • Air trapped in the cooling system during service
  • Improper sealing at the thermostat housing interface

Installation Notes and Tips

Verify the outlet port diameter, mounting hole spacing, and housing neck angle before installation. Transfer or install the thermostat separately, since it is not included. Use the included gasket and confirm the bleeder valve is positioned correctly during coolant refill and air bleeding. This part is listed for 1975-1979 Toyota Corona, 1977-1979 Toyota Celica, and 1977-1979 Toyota Pickup cooling system service.
