Since you mentioned that your Jeep is has the 318 (5.2L) engine I'm thinking that you are wondering about the timing chain? If you go to Google and type in "Dodge 318 timing chain" you 'll find a world of good sites including ones with step by step directions with pictures detailing how to change a timing chain on this engine. If you're talking about chains for the tires.....ummmm.......why would anyone need chains for the tires? If the snow is that deep maybe what you need is a SnoCat. If its not the timing chain then you need to provide a more detailed question for us to ponder. Brevity is nice but clarity is better. Good luck !!!
The timing mark is a line that goes across the harmonic balancer that should line up with the mark on the timing chain cover. It is on the drivers side on the bottom of the timing cover.
