W. Hallam - Head Repairs} 67 we think that some of the cases we have had to tackle re: overheating may have been due to the condition of the radiator core; we are therefore sending you an official order for 20 lbs of Kleanwell. We intend only to use this when we are limited for time, the method we wish to adopt being to let the solution circulate in the engine at a temp. of say 75° cent. using a solution of 2 lbs of Kleanwell to 1 gall. of water. What temp. and length of time should the solution be used in an engine? Do you consider it worth the cost re sending us a supply of Kleanwell; if not what is the next best solution you recommend?
