We just had an estimate done on our 2001 Ford Explorer and it was approximately $2500. We think that is extremely high so we are researching a second opinion.
Timing is computer controlled.
The 2004 Toyota Corolla has a Timing Chain and not a belt. No replacement is necessary.
The 4.0 liter SOHC - V6 engine has ( 3 ) timing CHAINS
The 2004 Honda CRV does not have a timing belt. It has a chain and no scheduled replacement is necessary.
If you look up the replacement parts for repair for the 2004 2.2 you will see the complete timing chain set. So, to answer the question it is a timing chain.
The 4.0 L - SOHC - V6 engine has 3 timing chains
Timing BELT - recommended replacement is at 105,000 miles.
I know that the 4.0 L - SOHC - V6 engine has 3 timing CHAINS
The Ford 4.0 L - SOHC - V6 engine has ( 3 ) timing chains
On a 2004 Ford Explorer : The 4.0 liter Single Over Head Cam , V6 engine has ( 3 timing CHAINS ) The 4.6 liter V8 engine has ( 2 timing CHAINS )
timing CHAINAdded: Check the above answer out carefully - I have an '04 and my engine has a timing BELT. Recommended replacement mileage for the belt is 90,000 miles.
we recently replaced our transmission on a 2002 explorer for $2400
