Two problems related to engine cooling system have been reported for the 2000 Jeep Wrangler. The most recently reported issues are listed below.
The engine has released more than one gallon of antifreeze into the oiling system in less than 500 miles. After removal of the valve cover, a fracture in the cooling system cylinder head water jacket has been found between cylinders 3 and 4 that permits coolant to enter into the oiling system. The dealership stated that the cylinder heads are known to crack without cause, can be replaced with a cylinder head that maybe prone to cracking again and in additon will require several more components to be replaced. The dealership offered no further information.

Return to dealer over 5 times before noticeable leaks stopped (behind dash board, floor at drivers and a passenger side) fix under originally warranty. 4 new leaks and return of two old leaks - not covered by extended warranty now dealer wants $650 to fix. Additionally have numerous transmission problems and paint rusting problems since a month after I purchase the vehicle.
