Anyone else have this problem, and better yet, how to solve it? My current ride is a GMC c3500 crew cab rig, 7.4 liter motor. My issue is the coolant recovery tank -- it seems to be leaking from the top cap area. Coolant seems to be weeping out of the top area with regular driving of the truck. I don't know about the rest of you truckers, but it's becoming a chore to clean the coolant recovery tank & surrounding area every few days. Has anyone else experienced this issue, and if so, how to solve it? My option so far is to replace the coolant recover tank completely with a sealed unit from Summit Racing. Does anyone else have a better suggestion? Any input is highly appreciated.
