Greddy alloy pulley kit - FD3S

Greddy aftermarket pulley kit to suit Mazda 13B fd3s engines. When the air pump is removed, the belt has very little surface area running on the water pump pulley, which often causes it to slip. This kit uses a custom larger water pump and alternator pulley to allow the belt wrap a lot further around the water pump pulley. No more slipping belt = water pump rotating as per factory. No more overheating engine from lack of water flow
