I have a 1999 chevy astro van. Need to change the waterpump Can't figure out how to get the clutch fan off. Have got the bolt out of the pully.But don't know how the fan comes off.
There is a special wrench and pulley holding set of tools.Most auto parts carry them now and they are fairly cheap.

Caution: To help avoid personal injury or damage to the vehicle, a bent, cracked, or damaged fan blade or housing should always be replaced.
