Fan, Fan Belts & Pulleys
The first MkVI (prior to VIN B213GT), Silver Dawn (prior to VIN LSCA9) and Silver Wraith (prior to VIN WHD77) models were fitted with a small, high speed water pump pulley (RE4736) which accepts drive belt RE20941.
In 1951 a larger, lower speed fan pulley (RE11270) was fitted and this accepted drive belt RE20950. The very last models in the range (R Type from VIN B325YA) were fitted with a later type small high speed pulley RE19043 which accepted the earlier drive belt RE20941.
This later high speed pulley is often fitted to earlier models as it offers more effective cooling so please be careful to confirm which fan pulley is fitted to your car.
