PTO/Hydraulic Pump

Chuck,

It's a good feeling when they're operating the way they're supposed too! True, with the A/C 'on' or the fan override 'on' the coolant temp pretty much locks at the 185* mark. If coolant temps don't modulate as described in post 15 then it's a good indication that you're fan is on high speed all the time. There's a fuse labeled "Ignition" in the grey engine mounted remote start box which feeds power to the systems involved. There's also a couple of related relays in that box. If anyone's fan is stuck on high speed the fuse and relays are the first thing to check.
