General Questions What is a crankshaft pulley?
A crankshaft pulley is the main pulley attached at the front of the crankshaft which drives all of the accessory pulley systems such as your air conditioning, power steering, alternator, oil & coolant systems. It is essentially the heart of the drive belt system from which all of the other pulleys receive their power, and thus must be properly designed otherwise problems & unforeseen complications may occur.
