Have a 03 gp se, of course the 3100 motor.
Does NOT HAVE a blown head gasket, brand new thermostat, new water pump.
Motor hits 250+ in a matter of a few min on first start of the day ( ie sitting 24 hours) and then a matter of second if it's shut off for 5 min.
I'm at a loss, auto shop is at a loss aparently they have no clue. I asked for a flush on it Mayne it is that, but they don't have a flush machine aparently.
Any other ideas on this?
