Biginuf, you might want to check out the tech section on speedtweaks.com before putting in the 160 thermostat, according to that page the 160 stat will trip your check engine light. They recommend the 180 stat.
he is right about the 160 degree stat. i do not know about the light, but it will not cool as well with a thermastat that is set that low.
i run the mopar computer, and from what i can tell, the more you add, the more results you will see. do not read the box, plug it in and think you just gained 30 hp and 5 mpg. you will have to do a cuople of the bolt ons to see a diffrance
You really dont wanna be running that low. the engine is most efficient at 210 degrees. i know you wouldnt feel comfortable running at that temp. if you have a problem with the cooling, get a radiator from a 2500 with a V10. my radiator is HUGE. a 180 thermostat would be the best to run. you could also try the stuff called water wetter by redline i think. it seems to work pretty well.
