The only Jeep engine that has a timing belt is the 2.4 Liter (DOHC) Vin#1 engine. All other Jeep engines have a timing chain. The belt should be changed at 120,000 miles under normal conditions and 90,000 miles under severe conditions. As this is an Interference engine and serious damage will occur if the belt breaks, I would use the severe schedule and change it at 90,000 miles. If the belt breaks it can cost you plenty.
