The Mustang V6 does not have a timing belt it has a timing chain which normally will last the life of the engine.
The V6 engine in a 2004 Ford Mustang has a timing CHAIN
The 4.0 L - SOHC - V6 Ford engine has 3 timing CHAINS
The manual states that the timing belt on a 2004 Accord V6 should be replaced at 105,000 miles.
When do you replace the timing chain on a 2005 Suzuki Grand Vitara?
Timing BELT - recommended replacement is at 105,000 miles.
The Ford 4.6 liter V8 engine in a 2004 Mustang has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS )
If the timing belt has not been replaced during prior visits the 105k interval is when it should be replaced regardless of inspection. It should be checked at 60k and 80k for the 1.8T, and if there are signs of wear at that time replaced.
No, the timing chain should last the life of the engine. No maintenance is required.
Never. This is not an item you replace at a scheduled time or mileage. It should last the life of the engine.
I would go with the recommended service interval found in the Owner's Manual.
Never. The Taurus engines...both the Vulcan and the Duratec V6s...both have a timing CHAIN that lasts the life of the engine, not a timing belt.
All BMWs since E36 have had timing chains not belts so they never need replaced.
