97 F150 Temp Gauge Problem?????
OK ladies and gents I really need some help.
My temp gauge goes from below normal to pegged instantly and the engine is not overheating. I've checked both temp sensors on the manifold and both connectors, they are fine. I've replaced the thermostat. The head gasket is not leaking, antifreeze level is fine, stays full. When the temp pegs the overheat light comes on then a couple min later the engine starts powering down (shutting down cylinders overheat mode). If I turn off the engine and restart it goes back to normal then repeats minutes later. If I turn off, then unplug both both sensors the temp gauge pegs again but does not cut off engine and will run fine. I have ran it 300 miles like that will no problems. I just can not stand not having a temp gauge. I'm pretty sure it is an electrical problem or computer problem.
Has anyone ran into this problem, any solutions. Yes I know get a aftermarket temp gauge and don't worry about it, but I don't want to stare at an overheat light forever. Is there anyway to shut this temp gauge off without shutting down the entire dash??
