I’ve heard about issues like oil pump failures, coolant leaks, and even timing chain problems in older versions. Are there specific things I should watch out for to catch these issues early? 
So, Jeep Grand Cherokees are generally pretty solid, but like any vehicle, they can have a few quirks. A few common engine problems you might run into include oil pump issues, which can cause low oil pressure—something you definitely want to catch early to avoid bigger problems. Coolant leaks are another thing to watch out for, usually from old hoses or a worn-out water pump, which could lead to overheating if left unchecked.
If you’ve got an older model, you might also encounter timing chain issues or problems with the lifters, which can cause some odd noises or rough running. Misfires can happen too, often because of worn-out spark plugs or ignition coils.
The best way to keep your engine in good shape is to stay on top of regular maintenance. Keep an eye on your oil pressure and coolant levels, listen out for any strange noises, and don’t ignore the check engine light if it comes on. Catching these things early can save you from dealing with bigger headaches later on.
