I was hoping someone could point me in the right direction on the jeep I just purchased. I bought a 1998 wrangler Sahara with the 4.0 auto. it is leaking coolant down the bell housing. about a cap full everytime I park it. I have read this could be a head gasket/head or a possible freeze plug. anyone have this issue? also anyone have a diagram of where all the freeze plugs are located? the jeep currently has 135,000 milel and doesn't seem to smoke or anything. thanks.
