Lidsey}6/MJ.17.11.32. THERMOSTAT SPRINGS. X3499 PN.{Mr Northey}1/WT.16.11.32. The two springs supplied for use in Phantom 11 trials cars are suitable for use in the 25 HP. car thermostat. There does not appear to be any reason why the 25 HP. car should not benefit by the same treatment as applied to P.11. The use of the spring in the 25 HP. car should raise the average running temperature to between 75° and 80° C. We suggest that you try the second spring in GAU.14 and we should be interested to hear whether you find it a definite improvement. Ha/A.J.Lidsey. | ||
