Re: Engine Temperature Gauge Reading

It is on but I think you have asked a question that has no definitive answer so lots of looks but no takers.

I think what is considered a normal running temp on an inline 8 is a big question to many. So many reports of engines running hot or overheating I doubt you will find a dozen with the same temp. I have read that a newly rebuilt engine will run warm until it loosens up. I hope that is true because my 356 seems to heat up to the range you mention after just a short time running. It hasn't been on the road to see if it gets worse or better with more air flow.

Only thing I can answer with certainty is the standard thermostat was 160 degree. The low option was 148-150 depending on engine and the high option for those in cold climates wanting more heat from the heater was around 190. Doesn't seem like a lot of difference between the low and standard range to make that much difference. Not sure what if any advantage there is to the 150 thermostat.
