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
