Looking for Grand Cherokee info

I'm finding that its a 3 chain system and is a bitch to work on.
 
My googlefu is failing me miserably.

2008 Grand Cherokee (WK)
4.7L PowerTech V8

Does this thing have a timing belt or chain? I can't find a definitive answer.

Timing chain as Crz posted. And as he posted, it's not very good and it's a pain to work on.

The 4.7 is not all that great an engine - the aftermarket has basically ignored it. The engine that replaced it, the new Hemi, has nothing in common with it and is far better.
 
Thanks!

It's my girlfriend's car that I'm just looking at from a maintenance perspective. I'm hoping to replace it with an SRT8 at some point.
 
Yeah the 4.7 has a chain, if a complicated one. There is no scheduled replacement interval, and the tensioners are usually the things that go bad rather than the chain itself - but even then it's not a common failure. A bad tensioner can lead to a rattling sound and a rough idle. Unless you've got a hojillion miles on it, I consider it an "if it ain't broke don't fix it" part.
