Thanks 8upZR1. I will get one of those without the notches and drill a hole to keep the temperatures equalized. Then I should be able to reduce the bypass flow at low enginr rpm.

Bob, Regarding the question of maintaining low engine temperature at idle, my 1993 will do that. I never could leave the car idling before I replaced the radiator. Now I can. Coolant temp stays at 198. I guess the engine heat load at idle is enough lower than the engine heat load at 1600 rpm and 50 mph that the limited radiator flow can keep the coolant temp down at idle.

Tyler, Thanks for the input. Do you think that a small hole drilled in the body of the thermostat would allow enough flow to ensure that the thermostat does respond to coolant temp?
