My buddy has a '93 Jeep Cherokee with a 4.0 HO 6 cyl. with 160,000+ miles. He was wondering what is the average mileage to change the timing belt? I did a search and found nothing. Thanks for the help!
The 4.0's don't have timming belts. They use a chain like the 4.2's. Not much need to replace unless you are having trouble with setting the timming. What will happen is the chain will stretch and give oddball readings and make it run a little rough.
1. IMHO... it's time for a little preventative maintance.
2. Fuel Injection has a "window" for the timing... and is somewhat forgiving.
3. If the chain or gears wear enough, then the injection timing can be exceeded.
4. The result is loss of power, stumbling, etc.
5. For the price of a chain and gear set...
6. Do the swap while it's still an elective fix,
7. At your time,
8. At your place,
9. At your budget.
