Daniel Boondocker Posted June 30, 2012 Share Posted June 30, 2012 (edited) Suddenly won't go below 215 on gauge even at idle once warmed up. Then overheats and buzzer goes of as soon as it hits a hill or in traffic and have to shut down. Not boiling over at all. Bought 2 new thermometers and water checks at 160. Any ideas. do I need to get something changed or recalibrated? Going to try a new temperature sending unit.
