I get the obsession part. When I replaced my engine, I went ahead and replaced my radiator with a Ron Davis unit. Overkill? Yeah, but I've had great experiences with RD products in the past. I wasn't having any overheating issues with the old raddy, but it was the original and I decided to upgrade while I was in there. I decided to wait and see how things worked before doing the fan clutch mod. Haven't had any issues so far, and it gets plenty hot here.I just purchased the truck about a month ago and am sorting out typical stuff and beginning the baseline process
Original temp gauge, runs at about the 2/3rds mark. Has not have an overheat moment but it operates on the warm side of normal. Have yet to do a chemical flush to see where it settles out.
Air conditioner slowly warms at idle and clutch is weak
Just all part of the obsession
