Playinghooky13 Posted 14 hours ago Share Posted 14 hours ago We just bought the fan clutch kit from mack to get rid of the cool logic clutch. I seen something mentioned here that a reprogram was needed for it to work. Does anyone here have the capability to do it remotely? I do have tech tool. Will it run at all without a ecm update if we have to make the trip to the dealer or will leaving the electrical unplugged keep it engaged? The truck is a 2012 chu613. Thanks in advance.
