The Jeep Grand Cherokee only has engines with timing chains from the model years 1993 to 2021. All Jeep Grand Cherokee engines from 1993 to 2021 are interference.
A combustion engine relies on either a timing belt or timing chain to maintain the proper timing and distance between its pistons and the intake valves and exhaust valves in the combustion chamber.
An old or damaged timing belt is prone to failure, which could lead to catastrophic engine damage and an expensive repair bill. A timing chain is less prone to failure but should still be inspected by a licensed mechanic once the engine has 60,000 or more miles.
It is generally recommended to change the timing belt starting at 60,000 miles, whereas a timing chain is usually good for the life of the vehicle.

Timing belt replacements can be expensive, but if a timing belt fails it will leave you stranded on the road and could damage your engine beyond repair.
When replacing a timing belt, it is normal to replace the water pump and belt tensioner while they are easily accessible.
