I was thinkin that my 3.o was running too cold because the needle barely comes up on the gauge. So to test my theory after i brought the truck to operating temperature (or at least i thought it was) and i took an infrared gun and pointed it at the top of the radiator right at the neck where the coolant flows in.

I am getting a reading of 165 farenheit.

Is this what everyone else gets?

If the thermostat is bad should i replace it with the 180 or 195 degree thermostat?

Thanks

I've had the same problem, and bought a replacement thermostat. 4crawler.com has a good discussion on the 2 stage thermostat which is applicable for the 22re, but I'm not sure about the 3.0. The feedback I've gotten is that if it is running cold, the t-stat is likely stuck open. Since it is an easy fix, through in a new one rated 190 and see whether that helps regulate the temp to more "normal" levels.

180* F, actually it should be 82* C. You don't want a 195* t-stat on an engine that has a t-stat on the return side of the radiator, and easily blows HGs.

ALWAYS buy the thermostat at the dealer. all other ones are crap and most of the time will stick very badly
