As with many other xj owners, my cylinder head is cracked due to the defective 0331 head. I bought the Jeep about 3 years ago, and about a year ago coolant started leaking into the oil. I talked with several mechanic friends and the head fleet mechanic at work told me the cracked head is extremely common. I was stranded on the side of the road, had to have the vehicle towed, and it sits as a giant paperweight in my garage as I cannot afford a new engine. I bought the vehicle with 122000 miles and have never taken it off road, modified it, or traveled more than 60 miles in a day. It has never overheated until the head cracked. Now I am looking at an enormous bill that my family cannot afford. I fail to see how so many vehicles can be affected and there is still no recall.
Temperature gauge showed increase past normal operating temperature and into red-marked range. After letting engine cool and shutting it off, coolant reservoir was empty. Refilled coolant and drove until it began overheating again, and coolant reservoir was again empty. No signs of coolant on the outside of the engine, none leaking out below. Suspect cracked head and coolant leaking into the engine.
I recently purchased a 2000 Jeep Cherokee with the 4. 0 motor in it. I have been having loss of coolant lately. No leaks no puddles but coolant is disappearing from my over flow bottle. A quick search on the internet revealed that this is a common problem with 2000 4. 0l motors. Turns out the head cracks. Closer inspection reviews a cracked head at 35k miles the Jeep has cracked a head. Unreal.
Freeze plugs failed in my 2000 Jeep Cherokee sport, causing the engine coolant to leak, and making vehicle inoperative. Cost of repairs totaled $1125. 33.
