What would you guys feel the best operating temp is?
I have a stock 180 thermostat and am not sure what temp the fan is supposed to come on at?
There is also a manual overide fan switch installed on the dash but I don't want it to keep jumping between open and closed loop or wear out the fan prematurely.
Any experiences / suggestions would be appreciated.

Thanks,
Ryan from Niagara

 

If you want, you can read about the cooling system here.

There is no danger of you going in and out of closed loop when using a fan switch.

"Best" questions are not usually easily answered. There are so many factors. Your car could run well in a range of 175°-210°.

 

thanks for the link - I recently replaced the coolant sensor on the water pump and idle and cooling seem to have improved - also glad that a manually overide fan shouldn't overcool the engine.

 

I run 210 degrees all day, stop-n-go and highway. (This is readying my autometer guage, too, not the crappy stock gauage) BTW, I have my both my fans on by 175 and have a stock thermostat.

 

Thanks - I'm in the same neighbourhood of temp. (with fan help when idling or driving it hard).
