grand coolant loss
bilge rat:
got a mate whos just bought an o2 grand cherokee, 40 petrol. about 250 mile it uses 3 pints of water. changed the rad cap no different . doesnt over heat at all. doesnt seem excess pressure behind rad cap, cant find any leaks, will be having a closer look tomorrow any advice or nown probs. i did work for jeep some years back but cant think of any thing , any advice would be apreciated. alan.....
tim_aka_tim:
Check the oil filler cap for chocolate ice-cream and exhaust for excess steam, but the AMC 4.0 is pretty bulletproof, so unlikely to be head gasket. Most likely to be water pump given up or hole in rad.

oil looks fine clean as it should, doesnt seem excess pressure. just watched him blast down the road .no steam.? i thought the same as you . i did work for jeep years ago but only changed a couple of h/gaskets. this ones only done 50 thou miles aswell. cant see any external leaks inside or out. bit of a mystery. alan.......

would be my guess also......but just in case have a look at the matrix also, if you have not already.

Yep, does the cabin smell of coolant? It would really reek - the stuff they use in Jeeps these days is foul!
