Does a 2004 Ford Exploer Sport Trac 4.0 V6 have a timing belt or timing chain. Depending on your answer, when should it be changed?
Timing Belt/Chain for 2004 Ford Explorer Sport Trac 4.0 V6 on 2004 Ford Explorer Sport Trac
Your 4.0L engine has a timing chain, regular oil changes chain should be good for 200,000 miles.
I believe your truck is driven by a timing chain, on a vehicle well maintained this is not an item that should be replaced in the scheduled maintenance.
it has a chain, dont worry about it
