My 96 F 150 over heated on me on my way to work. It has 270,000 miles. Engine was rebuilt about 10,000 miles ago. I've tried two new thermostats, new water pump, new radiator, new coolant temp sensor. When the engine runs for a few minutes the oil pressure gauge climbs nearly to the H, as the temp gauge rises. The temp gauge climbs to H and bounces back and forth to normal, it shows hi temp before any heat from the heater. The heat starts to work good and the gauge continues to go hi and normal. Oil pres. gauge remains hi with little fluxuation. I haven't tried to drive it more than a couple miles but engine doesnt seem to act like it is overheated (outside temp is about 10 degrees). No coolant in oil or unusual amount of white smoke from exaust,Thought maybe head gasket blown. not sure what to try next. If anyone has any suggestions I would appreitate it. THANK YOU

My best suggestion is to take off your radiator cap off and run the engine and add water to the radiator while the engine is running and if no coolant is going back into your coolant resiviour, then check your engine temp it should go down. If not then check your engine for any little small spots where there might be coolant sometimes little small tubes for collant will leak and it'll act like your engine is overheating...

Sounds like an electrical problem. Check the wires to the oil and heat sensors for bare places that are grounding out perhaps. Also make sure they weren't somehow switched around. You can put a mechanical heat gage on just to make sure it really isn't going up to a high temperature. If it turns out it really is, look for an air bubble in the cooling system.

go to the store and get a water temp gauge made by the aftermarket and install it, I think you will find out that your problem is all in the factory gauge.

Sounds like an electrical problem. I hate those, they are hard to run down. The mechanic could have crimped/cut some wires and caused a short that is interfering with the sensors.

I'd check for an air pocket in the cooling system.Also Have you checked the Temp Gauge?

whoever over hauled it may of reversed the connections your temperature sending unit could be faulty high oil pressure is better than low so there's no problem there

If it,s not boiling over ,Sounds like gauge cluster problems

take it back to the bloke who rebuilt the engine. if it is only doing it since then, well there is probably a problem with something he has done.

More likely then not,,you have a defective guage,and I wouldn't worry about it.As long as you have NO water in oil you are ok
