Running hot
 
When ever i run my ac..my xj 4.0 runs hot..so hot she's spilling out from the upper radiator hose..no ac she runs perfectly..fine around 210 degrees...what is going on..

Does the auxiliary fan (electric) come on when the a/c is running?

Do you still have a fan shroud? Very important part.

Running hot
 
Yes..i still have my fan shroud..but I'm not sure if my aux fan is operating when ac is on..how can i check aux fan..I'm thinking of putting in a separate on off switch for the aux fan so i can operate it manually

Pop the hood and see if it turns on while the a/c is running.

It's leaking from one of the ~2" radiator hoses? Or blowing out around the radiator cap?
