My 08' Sorento has 104,000 on her and runs like a dream. I know I need to change the plugs and have read several posts in here on earlier model spark plug removal and installation. Just wanted to know if anyone has any info or tips on changing the plugs on a 2008 model. Also, I've been worried about the timing belt/chain replacement. I have a 3.3 liter and it seems (from reading other posts) that I should have a timing chain and it doesn't necessarily need changing. Any info on that would be much appreciated.
