Not yet. I’ll add a new thermostat to the list. Does the cooler itself tend to go bad? I have a suspicion of a coolant leak somewhere but have not been able to track it down. I did not see any oil in the coolant reservoir, and the transmission oil looked fine (other than black) when I changed it and topped it off. It could also be the expansion tank but I’ll have to look around for any leaks. I have a code for a bad aux coolant pump so I’ll be changing that soon as well.
