RE: 09 Prostar running hot - Mt farmer - 05-18-2017
The last thing I heard from the latest truck shop is that the bottom of the radiator is cold, and the top is hot. They told me this is not right! What is a radiator for, other than to lower heat! Said I need a new thermostat. Rawze said it should have a substantial drop! I already put a new thermostat in it

Is it possible rhat there may be a nest in your exhaust or some kind of exhaust restriction? Kind of fishy that it started doing that after sitting. And it heats up just idling.

Hopefully it is someone that was highly recommended on this forum. Otherwise, you will be trading one kind of problem with engine failure issues. More bad tuning/del shops than you can shake a stick at out there.

Try to change oil termostat, i know one guy hes truck was overheating , running hot and turns out to be oil termostat. Changed that by himself and heating problem was gone. So you can try that. Lets us know.
