Engines that have a chain generally about 150,000 miles. Ones that have belts, 60,000 miles.
Actually , it has a timing CHAIN
60000 miles
On a 2002 Ford Explorer : The 4.0 liter Single Over Head Cam , V6 engine has ( 3 timing CHAINS ) The 4.6 liter V8 engine has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS )
The recommended mileage to change a timing belt on a 1995 Nissan Pathfinder is 100,000 miles. The belt may need replaced before this.
It does not have a timing belt, Chevy did not use timing belts in there truck engines.
BELT - factory recommended change mileage is : 105,000.
It depends on the engine type. On a 2.0 Petrol the recommended mileage to change the belt is 72,000mls, but you can always change it before.
The 1999 Ford Explorer has a cam chain not a belt. No maintenance is required.
Factory recommended replacement mileage is: 105,000 miles.
90,000 miles. 144,000 km
I would look in your owners manual and see what the recommended mileage is.
90,000 miles is the recommended mileage unless the car has been exposed to extreme cold or extreme heat, then 60,000. If you change the timing belt have the water pump done at the same time.
