Hi, yes engine definately overheating. Prior to removing thermostat, coolant boiling in reserve reservoir after shutdown. When overheating now, on shut down opening the rad cap releases pressure and boiling occurs in reserve reservoir. The car will run ok for sometime, but after stopping /turning off engine for 1hour plus, the problem of oveerheating occurs after a number of minutes after engine reaches operating temp. The original overheating problem started approx 1 week ago. Mileage 116,000 miles.
Hope this helps!
