Today I changed the power steering pump, after I was done I presure washed the front of the motor as the pump was leaking. Whent for a ride a few hours later and the temp gauge shot to the top right away. Back at home I cleaned all the pullys with some laquer thinner, tried again, temp shot up again. Squezed the top rad hose hot but no flow, checked the bottom rad hose and its cool. Also turned on the heater in the cab and it is throwing a lot of heat. I'm thinking the thermostat is stuck, any help would be great. Also is the thermostate beside the alternator on the top rad hose. thanks in advance for any input.

First check the overheat wire/sender on the drvrs side head lower front corner. The coolant temp sender is in the block just forward of the same head, behind the accessory bracket.

The tstat is at the base of the upper coolant manifold/rad hose (Goose neck). Only use Ford or IH tstats........ I don't think Tstat would be the problem since you concentrated in the PS pump area.

There should/may be a part number on the old sensor try and cross ref with NAPA, might need a mirror and magnifying glass. Also note the color of the insulator on the sensor.
