I hard wired the aux fan on and the temp stayed below 100C. It got pretty close in traffic but never hit 100. Went to 90C at road speeds. Don't know if it's an aux fan prob or fan clutch but I plan to replace the fan and clutch and put in a new sensor for the aux fan. Per another piece of info found here, I'm going to remove the aux fan and clean out any crap back there. I was able to stop the fan clutch by hand (Heavily gloved) with the motor idling at at full temp. Didn't feel like a real strong urge to turn but I don't know how strong it should feel anyway. The fan also wiggled a little so I'll just replace all that.
