On a 2002 Ford Expedition :
Only if it is noisy or causing a problem , it isn't like a timing BELT that
requires scheduled changes
* note , on the 4.6 and 5.4 , V8 engines there is ( 1 ) timing CHAIN to each cylinder head , so there are ( 2 timing CHAINS )
Timing chain usually needs to be replaced each 180-200K miles.
I just found out that it has a timing chain because mine is being replaced.
The timing chain does not have a service interval. It only needs replaced if there is a failure.
there is no timing belt -- only a timing chain that does not need to be replaced
2003 Toyota Camry 2.4L does NOT have a timing belt. It does have a Timing chain which DOES NOT need to be replaced.
Belt that must be replaced every 60,000 miles.
It has a timing belt that must be replaced every 90,000 miles.
That engine has a timing chain and gears and will probley out last the engine. NO need to replace it.
There is no scheduled replacement on timing chains (only on timing belts). Therefore, it only needs to be replaced if it breaks.
It depends on the engine. I have a 2002 Camry XLE with a 4cyl which has VVTi and it has a chain.
No, it has a timing belt that must be replaced every 105,000 miles. In 2002 Honda switched to a chain in the 4 cylinder.
it has a timing belt that should be replaced around the 90,000 km mileage
