Hi,

ok, yours has a timing chain, not a belt, which means that unless it has stretched and is making noise, there is never a reason to replace it. There is no maintenance replacement for the chain.

If it has stretched and is rattling, then you will need to replace the chain and guides:

first you requested the timing belt and then corrected to the serpentine belt. I provided both sets of directions. Was there something else, or something in the directions you dont understand?
