I have an amazing 2004 that just clocked 200k miles! Unfortunately, it is now overheating and heater only blows air temp.
Today, I tried burping the coolant system hoping that was the problem...~20min at idle adding coolant as necessary...coolant remained at 220f at idle but spiked to 240f within a short block of driving under load. There was no apparent leaking but I was able to add ~1/2 gallon of coolant after parking.
I suspect the water pump has failed but would love a second opinion or thoughts about what else I might try. Thank you!
