Does the 4.2 l. overhead cam V6 have a chain drive or a rubber belt like most 4 cyl.?

 

Moved to proper forum

 

If I put it in the wrong forum, where is it now?

 

If you scroll back up to the top of the page you can see the text that identifies this as the 3.8 & 4.2 V6 forum. You had posted this in the 2.6, 2.8, 2.9, 4.0 forum. You should get a better responce here...

 

The 4.2 is a conventional pushrod motor - no overhead cam(s).
It does use a cam chain, not a belt.
No routine maintenance is required.
Just have to replace it if it breaks. I have no recollection of ever hearing of one breaking.
