it helps a car move
^ gayest answer ever
It depends which "pulley" you mean. Drive pulleys are on the front of the engine.
If it does not drive anything it could be an idler pulley.
When looking at the engine from the front, the tension pulley is the only wheel on the drive belt that has the belt on the inside of it. All of the other pulleys have the belt going around the top of the pulley. The tension pulley has a bolt that can be loosened and then tightened to remove the drive belt.
The water pump is on the front of the engine. It should be close to the center of the block with a pulley for the drive belt on front of it.
The water pump mounted on the front of the engine, with a drive pulley attached to the pump hub. The serpentine belt usually drives the pulley.

The front cover of the engine provides a mounting place for the camshaft drive mechanism, front damper, and fan belt pulley. It serves as a protective enclosure for these components while also facilitating the alignment and attachment of various engine parts. The design ensures proper tension and function of the fan belt and camshaft drive system.

I'm guessing an older rearwheel drive? You should be able to find a different pulley to go on the water pump. From a car that didn't have AC. If front wheel drive, you will probably need an idler pulley and find some way to mount it.
Yes.
The pulley that actually makes the belt move is the crank shaft pulley. It's usually the largest one at the bottom center of the engine's front.
Think about your ten speed bicycle. The bike is in the lowest gear when the front sprocket is on the smallest diameter and the rear is on the largest. On the contrary, when the bike is at high speed, the rear is on the small diameter sprocket and the front is on the large diameter sprocket. Therefore, increasing the drive pulley size will increase the driven pulley speed (assuming the drive pulley stays at the same RPM). Similarly, increasing the driven pulley size will result in a slower speed (again, assuming the drive pulley stays at the same RPM).
