So I never had an over heating problem until once my fan got plugged up and it got real hot and boiled over. I got the fan free and cleaned the raidator but had no extra coolant to put in but I had to run it 10 miles back to the shop and re filled it. But now it seems as if as soon as the fan comes on it goes into limp mode(or it could be the opposite it’s hard to tell) but I think I got all the air out of the system but it’s still doing it. What could it be? Temp sensor? Still air in system?
