You can find out if a car has a timing belt or chain at www.timingchainorbelt.com web site.
If it requires a timing belt it probably is but not all engines have belts. The Expedition uses a timing chain. It doesn't have to be changed as part of a schedule like a timing belt.
No, under normal circumstances the timing chain will last the life of the engine and is replaced when the engine is overhauled.
The recommended timing belt interval is at 160000 kilometers or 100000 miles.
I have a 1999 silverado and it has 160,000 miles. It runs great and I have not changed the timing belt. Ask another mechanic for their opinion.
Timing belts should be changed at 100000 but many people never change them and don,t have any trouble. However if it breaks serious engine damage can occur
about 100000
Timing chains usually do not have a service interval. Timing belts do, 60,000 -100,000 miles
