I have a 92 2 door coupe. My engine has been overheating and then cooling back to normal almost immediately. A friend said the head may be cracked or the head gasket is bad. The engine has 120,000 miles on it. Have any of you had this problem? Is it common with the Legends with high mileage? Is it feasable to get the heads replaced (if that is the problem) or get an engine with low miles or get a rebuilt engine. Appreciate your comments.
