The 2001 Ford Explorer Sport V-6 has a timing belt. Ford engines have not use a timing chain since the 1980s.
Timing chain.
The explorer has a timing chain, not a belt.
In front of the Engine, under the Belt Covers.....
The 4.0 liter SOHC - V6 engine has ( 3 ) timing CHAINS
they do not have timing belts , they have chains , one in back of engine and one in front
The 4.0 L - SOHC - V6 engine has 3 timing chains
I believe the Explorer does NOT use a timing belt, but rather a timing chain
I know that the 4.0 L - SOHC - V6 engine has 3 timing CHAINS
On a 2007 Ford Explorer Sport Trac : The 4.0 litre SOHC , V6 engine has ( 3 timing CHAINS ) The 4.6 litre V8 engine has ( 2 timing CHAINS )
Never as it does not have a timing belt, it has a chain.Never as it does not have a timing belt, it has a chain.
Timing chains, no belt.
