Then I found out about the technical service bulletin from a Jeep website about this problem.”

“Within in the last 2 years, the cooling system has a had an off-and-on antifreeze leak. Parts replaced include the radiator, both the upper and lower radiator hoses, the water pump, the thermostat, and the freeze plug. A leak still exists, causing me to believe there is a defect somewhere not yet determined.”

NHTSA complaint #718497, filed 2000-02

“Fuel vapor line became detached causing fuel leak in close proximity to exhaust pipe which created a potential fire hazard. I repaired this defect by using a clamp to secure the line back to fuel tank. There are two of these vapor lines that are on each end of the tank and they are not secured with clamps from the factory. With the aging of the rubber vapor line it can become lose and when pressure in the fuel tank increases it can cause the one of the lines to pop off. …”
