Yea check all the hoses. And yea, help the husband. Because sometimes you need a second set of eyes to see the damage. Let me tell you how mine was overheating.
Somehow for some reason, the way they bent and twisted the hoses in my 99 trep does not make one ____ sense. My heater hose, as mentioned above by jgams was rubbing against the thick iron that helps to turn the wheels. So after a period of time rubbing against those irons the hose developed a half size hold, as big as a 5 cent. I would always hear hissing when I finished driving and the smell of coolant. But didnt realize where it was coming from, because the iron rubbed the hose so much that the hose became a part of it. Strange right? Hose and foreign iron.
Anyway to cut the story short, I change the coolant bottle, and all 3 hoses, and add a heat exchanger that doest not come on 98 or 99 intrepids.
Good luck........... good luck........
