| contd :- -5- Hsl/LG11.9.24. -------------- that it is not serious if the car boils because there is a limit to which this can go on - there is no possible means of his knowing when he has reached that limit until the damage is done. We think however that it can be definitely stated that either a 20 HP. or a 40/50 HP. car can boil for half-an-hou and the run continued without stopping to fill up with water.
