does anyone have a diy link on
changing my belts on my y8
because i looked yesterday and you have to
unbolt the motor mount in order to get one of the belts off

so any help is greatly appreciated

I'm assuming your talking about the power steering belt.....
You just have to support the engine by using a jack and a block of wood(so you don't damage the pan) and remove the side mount bracket. Just be careful to NOT jack up the engine too much 'cause you can crack the pan (aluminum pan)
