Engine Temp's - ZR-1 Net Registry Forums

A lower temp range thermostat is not going to help any when the temps rise above its opening point. All a lower temp range does it open it sooner. It has no effect on higher engine temperatures. Also I've been told by master tech level friends that too low an opening point isn't good for the engine either.

I need to check this out on "The Beast" to see if it is true or not, but if the engine temp is running high turn the A/C on. I know this may sound like a strange thing to do but on other vehicles I've owned turning on the A/C automatically turned on the radiator fans.

Another thing to try is to turn the heater on full blast. This sounds like an even dumber thing to do (especially when it is already HOT outside) but the heater core is nothing more than a small radiator. I've done this many times on my '70 and it does help bring the engine temp down some. Because the temp does drop when I do this means I have to take the radiator out and get it overhauled or replaced 'cause it's not doing the job it is supposed to be doing.
