| Contd. -2- Hsl/LG8.6.20. on the road, (air temp. 17°C) the temperature was 55 to 60°C, but of course, this depends entirely upon the condition under which the engine is run. The worst condition for freezing the radiator, is when the car is coasted down a very long hill. Hs.{Lord Ernest Hives - Chair} | ||
