X4412 X1298 ORIGINAL RE LOSS OF WATER IN HILL CLIMBING. X819 CJ13/ET/9/21 - It is not thought that the present cars lose more water than pre-War cars. We do not expect to be able to avoid a certain amount of boiling with the present engine and radiator. We do hope, however, to find a way in which we lose steam and not water. It is difficult to do this without altering the appearance of the radiator, especially at the top. We will take this matter up again and see whether we can introduce some other apparatus which will separate the steam from the water as it passes to the radiator under the bonnet. You will see mentioned elsewhere that the adoption of a new type of engine would, in my opinion, considerably reduce the amount of heat going to the cooling water. We could confirm this by a comparative test of the Hawk engine with the present 40/50 H.P. In any case, we should hope that in a newly designed engine there would be some improvement in this direction, and in the direction of the heat of the floorboards as well as many other improvements too numerous to mention at the moment. We will, however, endeavour to find some means of preventing the loss of water and allowing the escape of steam only, which would result in an enormous difference in the loss of water.
