WATER PUMP, THERMOSTAT & FAN. ____________________________________________ Herewith is E.CD.442 Arrangement of Water Pump, Fan & Thermostat. The water pump bearings, seals and assembly follow the 25 HP. Vauxhall. The fan bearings, and adjustment follow Wraith. Both these proposals are now being experimented with and results will probably be available before Bentley 50 has gone too far. An extra boss will be needed on the pump casing for the dynamo adjusting strip. Particulars to follows. DA.{Bernard Day - Chassis Design} | ||
