Thoughts on lower temp thermostat

Well, I guess I am not sure exactly how to properly burp the system...I opened up the radiator cap and overflow bottle, then started the car cold, and then added coolant until it was full. I waited for the t-stat to open up and watched the coolant level go down, then added accordingly. The car was parked on a very slight incline (nose higher than rear) when I did it. Does that sound correct?

Sounds OK to me. Just make sure you still have the proper amount in the overflow bottle.

Got it..Thanks!

this is an old thread, i don't even own that TC anymore..lol

I went ahead and replaced he 192 t-stat with a 180 (I bought it at the local Carquest). Car is running much cooler now. I did the same thing to my old 87 Ranger 2.9 V6; I ended up selling the truck with 240K miles, still ran like a top...I think keeping them cool makes them last longer. I am going to record gas mileage changes, if any and I will reply back, just in case anyone is interested.

Well, as everyone on the site told me to expect, my gas mileage dropped when I installed the 180 t-stat...Before the change I was getting 24.5 mpg city/hwy combined. With the 180 t-stat I have recorded two consecutive weeks of combined driving at 13.8 mpg. Ouch! My 4 x 4 truck does better than that!

combined driving at 13.8 mpg

Ouch is right! Sounds like too much to be just the stat, but that is only a guess. I didn't lose anywhere near that when I went to a 180, but I don't drive it in cold weather either. Are you sure that is the only change that was made?

The weather has been exceptionaly cold around here lately, which think has contributed to some of the decline in mpg. I'm waiting until I install the Autometer temp gauge; I want to get an accurate reading, then I'm going to switch back to the 192 - with no additional changes - and see what happens...
