Thread: thermostat

I've run 180* on my Imp for over a year, no low temp code. Still going back and forth whether to do the "winter switch" on my thermo on the Imp.

Unless its drilled, why would you need to change it?

With the colder weather, the car will run cooler, and it won't run as efficient. Gasoline powered engines run most efficient at 195* - that's why that's the standard rate. I put the 180* because of the other mods I did, and I wanted to make sure I didn't burn it out. When I got my GP, I had to replace the thermo. I put in a 180* with zero mods, and a shop that looked it over noted the car was running cool. They thought I had a 160* thermo in it. I switched it to a 195* since I don't have the mods that really require the lower temp one. It was a previous discussion here when I asked if a car could run too cool. I didn't change it last year, so I'm not in a big hurry to do it. What I'd need to do is run the Imp with 180* for a week or so and then again with the 195* I can pull from my GP and compare MPG on both.
