I have an 02 TJ, at around 24,000 miles i noticed coolant missing. after many visits to the dealer and local mechanics, it turns out the head was cracked. The head was replaced at 30,000 miles this past July.
The jeep now has 40,000 miles and two weeks ago, i noticed the coolant level dropping yet again.
Does anyone know what the flaw is, and why these heads crack so easily????
