    Hi, I have a 2004 Chevy Colorado 3.5L... I know the original thermostat releases at 180 degrees. The new ones release at 190 something.... does anyone know of a thermostat that releases at 180 besides the Stant Thermostat?

  7. Engines/Performance/Tech Questions
    For awhile my canyon was running hot. At the 3/4 mark. I've changed the fan clutch, thermostat, water pump witch was leaking, and I also changed the temp sensor.
