I am putting a 180 degree thermostat in my 2010 Challenger 5.7. When refilling the coolant is there anything special I need to do? Or is it just like filling the old style cooling systems? Thanks for any help. Matt
Thanks for the input guys, yes I was just putting in the thermo so I filled it like normal. Roadman, I read some posts on here that a 180 thermo will give up to 30 more HP. There is a noticeable difference for sure.
