My UD pulleys came in today and it looks like the water pump pulley has no way of keeping the belt from sliding off. The original pullley has some raised sides on it compared to the new one which is flat. Are all the water pump pulleys like this and has anyone ever had a problem with them throwing a belt off.

No, the tensioner will hold it in place. I never had any problems with it.

The belt won't come off. When they were made like that, without the lips, a lot had that concern but the tensioner keeps it in place. It won't come off.
