MotoRad 160F Thermostat with Housing and Seal LS1

Keep your engine temps down during the hot summer with a 160 degree thermostat. Modifications to your tune may need to be made to prevent throwing a P0128 code for Coolant Temperature Below Thermostat Regulating Temperature. The computer will assume your thermostat is stuck open as it will not reach the normal hotter operating temperature.
