Belt Drive Replacement Dual Alt

I'm doing the whole deal, tension, etc. are the top and bottom pulley wheels the same part?

Or is the top smooth and the bottom grooved?

Van same as truck?

Here's a clip from the service manual showing the differences between pickup and van.

The crank pulley is grooved, so any pulley that has the belt going in the same direction would also be grooved.

Looking at the front of the engine, does the belt run clockwise?

I think counter clockwise, but I'd have to go check. You could tell by looking at the fan blade direction. The forward edge of the blade would be the rotation direction.

I've never looked under the hood of a PSD Van but I think the belt will run the same way the crankshaft turns. I've never seem a crankshaft that didn't turn clockwise when viewed from the front.

...clockwise when viewed from the front.
That's called "counterclockwise". All directions on a vehicle are given from the primary operator's position.
