Coolant system question
 

Ok my question is this , my 1989 xj 4.0 has been torn into and is missing the coolant bottle and all the stuff that goes to it including the heater valve and all the hoses and assemblies...basically the hose comes from the w/p and goes back into the block in a u-shape. It doesnt overheat that I know of...no gauge just idiot light and who knows if that works....my question is does anyone have pics of this area or can anyone tell me what parts i need to scavenge...also will the parts from a 1996 cherokee 4.0 work for my application.
