Not sure how you thought I was going to do this myself, all I asked for what was involved in fixing it! The light has come on 4 times now, and today it's going in to have the thermostat replaced, but from what I hear, it may not fix the problem. Another Jeep Cherokee owner has the same issue with the same 2.4L Tigershark engine.I would suggest having your dealership check this out, worldtriad. Performing DIY repairs has the potential of affecting your warranty.
Mine finally came in and it's schedule for today. Yes, I have that engine. I have no idea how long it will take them to do this; I hope not too long. I have a creak, like bushings or something in the front end I want them to look at while they have it.You will need a new thermostat and it comes with the housing, at this time they are on back order. I would take it you have the 2.4l engine
