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.
on the crank behind the drive pulley and harmonic balancer
Turn engine with a socket on the front crankshaft pulley.Turn engine with a socket on the front crankshaft pulley.
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.
calculate speed drive pulley.
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.
The "driving" or drive gear is the source of power or rotation. The driven gear is turned or moved by the drive gear. Example: The pulley on a motor is the drive pulley and a pulley on a pump is the driven pulley. Example: The pinion gear in a differential is the drive gear and the ring is the driven gear.
