Primary fan comes on at 185 off at 175.
Secondary on at 193 off at 184.
Has a 160 thermostat.
Even on a 50 degree day primary runs constantly at idle.
Engine temp will not go low enough for primary fan to shut off.
Is this causing any ill effects for engine?


I unplugged the primary today. Temp goes up to 193 before secondary comes on.
But doesn't shut off idling on a 50 degree day even with heater on full.
Temp remains about 187

Someone has played with it my stock 94 comes on at 228 and 238 or come on if the defrost or the a/c is on. They are ment to run like this do not belive it will hurt much other than burning your fans up.

You do not want an engine to run warm. I am not stock, but I don't want to see my motor at 200 degrees.

You are better off with your settings like this. Leave it alone. C4's can get warm for several reasons, use the tools the car has to keep it alive and happy. Just my opinion. None of my fun cars ever ran as hot as people let them on these boards.

LT1 engines are designed to run at temps determined by degreed people for specific purposes. Those of us without 'automotive' engineering degrees might better serve this board by keeping our uneducated tenets to ourselves.

The following link provides a comprehensive analysis for cooling the LT1 engine. The basics were not designed at the whim of one individual, but by a team of development engineers, supported by product test people, and by quality control people.

Unfortunately the person who wrote that article at the end says he thinks it runs too hot and made multiple provisions to drop it down to the 200 deg area.
