overheating after presure wash

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.

Thanks for the ideas cdnsarguy, this morning when I whent to start the truck the temp gauge shot to the top and check engine light came on. Disconected the wire on the lower side of the front head and light whent out, checked the wire and sprayed wd 40 on it. Seems to be okay now, phoned for a new temp sensor from Ford $90. think I'll wait and see if keeps working befor replacing the part. thanks again
