Well, beings the car is a 2005 I would think it has a first design timing chain setup, but from what I am gathering from trying to purchase a timing kit on Ebay, the first design has roller cam chains and a silent link primary chain. But my setup on my 2005, VIN 7 3.6 has all three of the silent link style chains which I think I found but then they describe the primary chain having 96 links and the cam chains having 114 links. My primary chain has 48 links and cam chains have 57 links. I cannot find anything setup like I have. What is the deal?

Welcome to 2CaroPros.

I looked up the OEM part numbers for you. Use them to cross reference chains from other manufacturer's.

As far as getting the part online, buyer beware. You don't want to get the wrong or a cheap duplicate of this one. I have a feeling you are seeing the timing chains for other engines that came in the vehicle.

Here are the OEM numbers:

12590920 is the primary

12589011 Is the secondary.

__________________________________________________

I don't know if you need it, but here are the directions for replacement. It is broken down to left and right secondary and primary. The attached pictures correlate with these directions.

I will separate each one to help avoid confusion.
