Timing chain replacement instructions needed

Hi, my friend just recently was given the car listed above by his aunt. He was told that it needs a timing chain replaced. Both him and I have a little bit of experience with timing belts as I've done then in the Camry and Lexus gs400 and the timing chain on the Lincoln zephyr I once owned. So, he asked me if I could give him a hand with it and I said sure. So, I was wondering if I could get the procedure on how to replace the timing chain on his car. I want to make sure we get everything done correctly.

Thank you,
Rob
