Hi All - Deep into oil pump seal work and therefore have the fan off. It's been running a bit hotter than I'd like with poor A/C performance at stop lights. Thus, thinking of a fan clutch improvement! I have this one that came off the rig - could be original or not (the torx bolts make me think aftermarket). If it's an original and better than the blue hub I will mod it. If not, I have a blue hub here ready to be worked on. Anyone have an idea which clutch this is?
