In Reply to: Is a gutted thermostat a good Idea????? posted by PJ on May 24, 2001 at 19:57:54:

Thermostats serve to keep the engine at an optimum temperature. The radiator cooling capacity is greater than the engines heat producing ability under most conditions. Thermostats also serve as a restriction to the flow rate allowing the water more time in the radiator core to cool down.

If you are having temp problems stick with the basics. Flush the system, verify no leaks, water replace thermostat, be sure radiator is good, water wetter. I have seen old radiators that look fine but just do not transfer heat. If problems persist check timing, mixture, head gasket, cracked head, etc.
