RADIATOR CORROSION. In a recent Depot Sheet we recommended Ethylene Glycol as an anti-freezing compound. Further experiments that we have made indicate that Ethylene Glycol reduces the amount of corrosion which takes place in the cylinder block and head. We are, therefore, contemplating recommending the use of a certain amount of this substance in the cooling system of Phantom ll cars. In order to gain experience we think it would be invaluable if the London Trials cars could be treated with Ethylene Glycol where they will be under observation. We suggest a gallon and a half in each system. As corrosion will have already taken place on the existing trials cars it will only be possible for us to use them as a means of ascertaining whether any troubles are likely to arise from such treatment of the cooling system. If a new Trials car is put on the road, however, we should be able to confirm tests we are doing on our Expl. cars, as to absence of corrosion after a considerable mileage.
