T-stat at 165F ?
T-stat at 165F ?
My 1970 4x4 355 runs at 160F . Driven all day no more then 165F I thought I put in a 180F t-stat but what the hell?Do I need to bump it up and run at 180F-190F? __________________

Best temp for a engine is in the 180-190 ranges as you say because this keeps all moisture from forming.

If you do have a good 180 thermostat you may have a bad sending unit or the guage could be out of calibration.Also it might not be the right sending unit for the guage.

I agree, the guage could be bad.. 15-20 degrees off could be a possiblity.
I acutally prefer a 195 degree stat for wintertime, but i have a 180 in the truck right now. Seems to work well for both summer and winter. With a 160 degree stat my heater has never very hot.

I have seen this a lot in trucks...maybe it has to do with all the airflow the radiator gets...you can put in a new stat drive down the road...it will heat up to 180, if that's what you have in there, but once it opens it never closes again and the truck wants to run around 160. I have never really solved the problem, but what I do is cut a piece of cardboard that covers about 3/4 of the radiator. With the cardboard in place your heat will work great. Kinda redneck but it works great and the price is right. I have done this on every older Chevy truck I have owned

tom hand,
I've done that before. Had an old Ford once, it would never get hot. Put a piece of cardboard in front of the radiator, I was toasty warm after that. My 70 GMC has a 180 degree now, it gets too hot sometimes. ![]() ![]() ![]()
