De/Rm{William Robotham - Chief Engineer} o.{Mr Oldham} De/ID IOHH DA.{Bernard Day - Chassis Design}9/G.26.1.39. C.I. CONVENTIONAL 6 - WATER PUMP, FAN AND WATER CONNECTIONS. Please receive herewith :- E.CD.1168 Cylinder Head, Front End, Water Pump, Thermostat and Water Connections. C.I. Conventional 6 in B.V. chassis. This completes the information for cylinder head E.CD.1167. The thermostat casing and also the water pump casing are both modified from the B.60 parts. The fan hub and spindle have been lengthened a little from the B.60 fan E.CD.678, in order to improve the clearance between the fan blades and the top water connection to radiator. In order to supply a drain tap for the water system, we have shown the tap in the radiator bottom tank, this means that the shape of the bottom tank is modified to accommodate the tap, otherwise the radiator is the same as for the B.V. chassis to designs FD.{Frank Dodd - Bodies}164 and FD.{Frank Dodd - Bodies}165. The front engine mounting is the same as for the B.60 engine to E.CD.785. Will you please detail and instruct for all the new parts to be produced experimentally.
