Timing chain/belt and water pump

I've a 1998 Jeep Cherokee (4.0L). I Love it. It has 135,000 miles. Question?--When should I/when should I have, changed the timing chain/belt and water pump? I have my truck serviced at a Jeep dealer and they've not recommended such service. I prefer 'preventative' maintenance vice 'breaking down'.

On your Jeep Cherokee you have a timing chain that is made to last a much longer time then timing belts, under normal service it is not requred to change, on the other hand it is recommened you replace the water pump and all coolant hoses and renew the coolant.

Does a 1996 Grand Cherokee Jeep have a timing belt or chain? And does either need changing?


That depends on which engine you have. Both 4.0 and V8 engines have a chain. The chain has no real time limit on how long it's good but from experience I've found that most, when well maintained will stretch to the point that they should be replaced at around 225 thousand miles.
Chain and gears are not super expensive and if you buy the best ones you can find, if you replace yours at 225-250 thousand miles the new one should outlast the vehicle.

1998 grand cherokee 4.0 eng. crank shaft pulley,is there a back piece for the belt to go on?


are you talking about the serpentine belt or the timing chains, the serpentine belt is what drives the alternator,power steer,water pump, and goes around a few idlers. and around crank pulley that is in front of harmonic balancer. Did the belt fall off? is the pulley missing? cause it should be very self explanatory and visual.

2002 Jeep Grand Cherokee timing belt/chain replacement (not 4WD)


I BELIEVE THAT IT HAS A TIMING CHAIN. IT SHOULD BE CHANGED AT OR ABOUT 100,000 MILE. BUT IT DOESN'T NECESSARILY NEED TO BE CHANGED THEN, JUST INSPECTED.

Does my Civic have a timing chain or a timing belt


It has a timing belt. Recommended to be replace every 105,000 miles, timing belt also run's your water pump good idea to also replace, your engine is also an INTERFERENCE ENGINE which will damage your cylinder head valve's if timing belt goes bad. Hope this was very helpful.

Hello, got a car question for you fine people. My friend had a timing chain that broke on his car at 50,000 miles. Kinda early for something like that I would think. What would cause a timing chain to go...


50K miles IS premature for a chain to break. They're pretty tough. Are you sure it's a chain? If it is a BELT, it could be old and broke due to age. They are a synthetic rubber and eventually they deteriorate over time.

You don't specifically state what kind of car your friend has, so I am presuming a 1998 Accord. That car should have a belt.

Either a belt or a chain can fail prematurely if the tensioning system fails. This will allow excessive slack in the chain or belt which will cause damage to the affected drive components. The tensioning systems can fail due to one or more of the following:

Lack of oil pressure, failed tensioning springs, failed pulley bearings, over-revving the engine for ridiculous periods of time, and failed plastic guide components.

Belts can also fail due to chemical contamination (oil or antifreeze leaking on the belt).

Finally - the water pump can fail which will derail the belt as the belt drives the water pump on many Honda 4 cylinder engines.

Do you need to change the timing chain on a 2003 Jeep Grand Cherokee at 75,000 miles?


You will not need to change a timing chain unless you know or suspect it to be bad. Belts and other material that wear down need to be changed but the timing chain itself is a metal similar to that of a bike chain but much shorter and thicker
