You would use a 5 inch sheave.
There are four steps on how to measure pulley size. One of the step-by-step instructions is to diameter of driven pulley) times (revolutions of driven pulley) divided by (revolutions of driven pulley) equals (diameter of driver pulley).
It has only one belt. The drive belt drives the Alternator and A/C Compressor and is driven by the crankshaft pully and the slack is taken out by the tenioner pully. It dont have a timing belt,it has a timing chain.
An idler pulley is a pulley that does not drive and is not connected to any device that is driven. It serves to either tension a belt or to route a belt to clear an obstacle.
The fan directs air flow through the radiator so heat energy can transfer from the coolant in the radiator into the atmosphere.
On the four cylinder it is directly behind the fan pully. on a six cylinder it is behind the timing cover and is timing belt driven.
the proper way is with an installer but its not cheap sometimes you can rent tools like this at advanced or autozone if not i have driven them on with a hammer many times i just use a block or a buffer between the hammer and the pully if you listen to the sound when you hit the pully you will hear a diffence in sound when it is fully seated
A pully is something that has a pully circle and you can just pull on it to make the object move but if the object is heaver then you you need to put a movable pully so it is easier
wrap the belt around the pully to hold pully still
If you decrease the size of the driven pulley the fan will turn faster. You can achieve the same effect by increasing the size of the drive pulley.
A pully is used to lift thing depending on how big the obJect is
