| To R. {Sir Henry Royce} From Hs. {Lord Ernest Hives - Chair} c.c. to Ss. {S. Smith} HOr. c.c. to E. {Mr Elliott - Chief Engineer} Ds. c.c. to Hy. {Tom Haldenby - Plant Engineer} Hs. {Lord Ernest Hives - Chair} 2/WJ.2.12.29. X4576. SODIUM PHOSPHATE IN RADIATORS. We find that if we get any excess Sodium Phosphate in the radiator water that it will prime and cause loss of water as you suggested. Until we have had more experience with it we consider it should not be used on customers' cars. Hs. {Lord Ernest Hives - Chair} | ||
