So I’ve finished replacing the cylinder head temp sensor & fan speed resistor on the TC and here are the updates. I ran the vehicle with hazards on, high beams on, AC on recirculating main vents on “4” (high), front and rear defrosters on, windshield wipers on just to stress test the vehicle for about 20 minutes with no overheating issues and the fan kicking on every minute or so to keep the engine cool. I’m going to run it for another few hours at my current setting (3/4 heat, and notch “1” (low interior fan speed, good for working in the back of the van) to see if it still smells like burning / shows fresh oil near the gasket.
I ran it for about 4 hours total, and the only smell I smelled was the engine degreaser burning off. I actually turned off the heat after one hour, and still nothing burned. I checked around the seal and no oil formed. I have to make a 250 miles run at the end of this week, so I’ll see what happens during that. Thanks again for all your help!
