Hs{Lord Ernest Hives - Chair}4/LG31.3.25. OBJECT OF TEST. Cooling of EAC: Engine Radiator. TESTER. W. A.{Mr Adams} Robotham. CONDITIONS. Road tests carried out in a similar manner as described in Hs{Lord Ernest Hives - Chair}7/LG28.11.24. 44-PK 'V' series was fitted with latest EAC. undershields. SUMMARY OF TEST. The temperature figures given in the attached report is the air temperature at which the car will boil if run full throttle. It will be seen that by comparison, although we are using the same size of radiator on the EAC., that we heat less water. We should have less trouble with boiling although we do not anticipate we shall be free from it. The improvement with the bonnet shutters open will be the same as on the 40/50 HP.
