The Jeep Grand Cherokee 3.0 CRD is equipped with a timing chain, but it may experience various engine issues. It's important to promptly address any loose gaskets to prevent further problems. Oil leaks should be fixed without delay, and keep an eye out for spark plug issues that could cause engine trouble. Engine overheating is a serious concern that can lead to car fires and explosions. Keep an eye on oil consumption and change it promptly when needed. Remember to change the air filter every 15,000 to 30,000 miles, replace the coolant every 60,000 miles, and swap out the spark plugs every 100,000 miles unless you have a copper one, which should be replaced every 30,000 miles or so.
