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 chains usually do not have a service interval. Timing belts do, 60,000 -100,000 miles
about 100000
Every 60,000 miles
No, uses a timing chain. It should never need changed. If you take halfway good care of the vehicle it will last 200,000+ miles. I have owned two old toyota celicas with timing chains and they both had over 250K miles on them without ever changing the chain..

The V6 has a timing belt that MUST be changed every 105,000 miles.
