Im looking at a 6pc set for an 08 3G found out mines were cracked im wondering why its 6 pieces I know the front side rear and 2 tranny mounts but whats the last piece is there some kind of bracket for one if the engine mounts?

Last but not least is there a DIY for mounts and replacement of the drive serpentine belt?

 

this might help for the mounts: https://acurazine.com/forums/3g-tl-problems-fixes-114/replaced-my-motor-mounts-pics-inside-772642/

there should be a DIY in the 3G Service Department for the belt.

The serpentine belt is pretty straightforward. You need a 14mm socket and a breaker bar or long handled ratchet.

Take tension off the pulley and the belt comes right off. It takes some fanangling to get belt off the lower front side and putting the new belt on takes a little finese as well. But should only take 20 minutes or so.
