OK....................
First off, "Take the doors off" on an XJ? Inquiring minds just gotta
ask, How?
You are describing a failure of the viscus fan clutch on the radiator
fan or a failed electric booster fan on the XJ long rad.
Both are easy to check. First on a hot engine, have someone shut it
down while watching the main fan to see if it stops almost instantly.
If it freewheels on a hot engine, the clutch is toast.
Then turn on the AC on a hot running engine and the auxiliary fan should
turn on.
