guys (gals?)

is timing belt same as serpentine belt?

I replaced timing belts - 2 of them - on Subaru - what a nightmare!

I replaced timing chain on Dodge Ram - tedious but doable.

What about the 2.0 L4 Zetek - doable for do-it-myself-mechanic like me?
Do I have to un-bolt engine mounts?
Any free instructions on-line?
