The electric fan will only come on with the AC or if the engine gets
'really' hot, like way up in the red I believe.
The Cherokee with no AC doesn't have this electric fan.
The bottle should have a mark on the side about half way up showing the
fluid level. One thing to watch for that will air lock it is the line
running back from the front. If this gets above the level of coolant in
the bottle, it will air lock so you barely get inside heat and the
circulation to the bottle gets restricted so it runs 'hot', but not
boiling over. Ours was like that. Lowered the line and got great heat
finally in it.
