| -2- Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}15/KW.1.7.35. (4) We are now of course cooling our oil with the car radiator. In your last report you state that the oil was 100°C. and the water was 100°C. It is possible that this oil cooling may not be necessary on the SpectreCodename for Phantom III because by those figures the oil was no hotter than the water. We should like you to prevent water flowing through the cooler and measure the oil temperature to see if it remains reasonable.
