GDP-63....Geoffrey Smith. Replying to C15/C3.7.31. There is no doubt that by fitting a new matrix to Mr. Geoffrey Smith's car a definite improvement in the cooling efficiency will be obtained which for hill climbing should amount some 4°C. Still further improvement will be produced by the louvred bonnet,. If Mr. Geoffrey Smith is to be given a new radiator centre with the dented tube, his radiator will have to be pulled to pieces, and therefore we would suggest fitting him with the anti-spill radiator cap. An endless fan belt is a simple matter and though we do not anticipate that his previous trouble was due to his fan belt slipping, we think it is a good idea to make this alteration as an assurance. We consider that these four modifications cover all the useful work that we can do to prevent the car overheating. We do not think the free exhaust would be worth fitting. In any event, we have no design which has been tested experimentally. Whilst we cannot guarantee that GDP-63 will not overheat under any conditions with the suggested modifications, we consider that the heat will have to be very exceptional before boiling takes place and the car should be vastly better than previously.
