Hi all!! Finished up installing new used EA82T engine in the XT 4WD Turbo last night. Took it for a spin last night. Runs great and we love the power. Only one thing has us stumped. Electric cooling fan runs all the time. We have uplugged it for now. Relay is working. Possible bad switch??? Any suggestions would be appriciated!!! Thanks

thermo switch on the rad is probably bad. When they go the fan is in fail safe mode....which is ON at all times.

Ive never had one fail like that??

most burn open from too much current

guess they could weld closed though

simple to pull the wires off of it and check.

sorry no relay involved with the thermoswitch

the relay is for AC control of the fan

the fan should run anytime the AC system is
engaged (like in defrost mode)

are you sure the defrost button is not pushed?
