Ive noticed the 4.0 doesn't airlock. Thankfully the blocks slant
and position of the radiator keeps that from hapening.

Guessing he knocked off one of the electrical connections to
the fan by accident. (or on purpose to try to rip you off)

Re: 2001 JGC - coolant change = radiator fan stopping
 

The switch for the fan is where the top rad hose clamps on. Sounds like
they broke or unhooked it.

Or the sucker just up and failed.... If you put 12 volts to the fan and
it works, then the switch is suspect.

The gas receipt would be a good way to prove it was working like the
other poster mentioned.

Re: 2001 JGC - coolant change = radiator fan stopping
 

Thank you to you and everyone else who replied. I'm going to talk with
the corporate office service rep before I do anything. I'm hoping they
can first, talk sense into this guy, second, see if they'll pay to get
it repaired. If anything I can try what everyone suggested.

The service person said that he "connected all the wires and it still
didn't work." I'm suspecting he knew about the switch on the top of the
radiator hose. I followed the electrical lines as best I could
yesterday and everything seemed plugged in, but I didn't follow it all
the way to the line to the fuse box.
