Hey all so my car has been running cool for a while now, being constantly at 120 degrees even when driving for a while, it only climbs if i idle for about 20 minutes and it goes to 160 max.

I have changed the heater core, thermostat and the radiator cover. No leaks have been seen or anything of that sort, i do blow out kind of thick white smoke when cold until it warms up but i also have no cats .

It never overheats nor does it get even close and takes about 15 mintues to warm up the heater temp to. any idea's? And should i be expecting any bad effect from this?

are you going by the gauge in the car?? or do you have an aftermarket gauge

ScreamnV8

it is an aftermarket gauge in car and on radiator cap, cap will say about 80 degrees while gauge in car says 120's or so.
So it shows that the radiator is staying cool but way to cool.

Change your thermostat, get a MR gasket or Stant 180 or 195. I've personally find that engine temp hard to believe.

Its a brand new stant 195 degree i believe with new gasket. All should be where it is, but isn't. ?

I can't see a motor running at 120 degrees even with a stuck open t-stat unless there are several cyls not firing.

Would probably take a seized fan clutch along with stuck open thermostat and multiple non-firing cylinders

It runs a little sluggish but really doubt that it is misfiring, it is odd i know. i have yet to come across anything like it. I DO how ever have a vented hood which i have had in the past before and it has cooled some but nothing to this extent?!?! Unless the new stat is already stuck opened. i am at a real loss.

If its in backwards, the water pump pressure will open it right away.

I'm pretty sure it was installed correctly, the top (triangle part) is pointin towards the radiator area.
