Belts have consistent small cracks

What is the trick to changing the belts on this car?

Pretty easy to do. Loosen the belt tensioner, take the old one off and put the new one on. Make sure you have a diagram on how to route it before you take the old one off.

A series of small cracks doesn't mean the belt needs to be replced. I would ask a dealer what MB specs are. I was told by a Ford dealer mechanic and Ford allows up to 4 cracks ones going through the rib, per 1 inch area.

Thanks guys. I'll probably hold off on changing for a little while, but I'm going to order the belts just so I'll have them ready in the event one breaks, or I start to see more significant chipping.
