Okay, so after installing the correct clutch fan, and sealing off the fan shroud temporarily, the issue persists.
I did notice at the start of this test drive, my temperature fluctuated for a minute or two, but settled in where it normally does.
Upon return, I popped the hood to check things. Upper radiator hose is firm and hot. Heater core lines are warm. Inlet side of radiator will burn your hand after a quick second. However, outlet side of the radiator is MUCH cooler. Radiator cap is cool as well.
I‘m lost. The firm/hot upper hose is telling me the thermostat is working. I can’t imagine having multiple new ones in a row cause the same issue. The radiator having such an extreme temperature difference and a cool cap concerns me a little bit. To me, that indicates a plugged radiator, but it also should be overheating, not overcooling. I’m half tempted to throw a new one in it anyway. Maybe replace the thermostat a 4th time. Ugh.
Any other suggestions?
