allow the water to enter into the cylinder head connection and to flow through the water jackets and out at the side inlet connection.
| Will the Radiator freeze in winter? | Answer No. 40 |
Yes, unless an anti-freezing solution is used in the circulating system you are bound to experience trouble. As the circulation does not commence until the water becomes heated, it is apt to freeze at low temperature before it commences to circulate. In case any of the radiator tubes happen to be plugged or jammed they are bound to freeze and burst open if the driver undertakes to get along without using a non-freezing solution. Wood or denatured alcohol can be used to good advantage. The following table gives the freezing points of solutions containing different percentages of alcohol:
20% solution freezes at 15 degrees above zero.
30% solution freezes at 8 degrees below zero.
50% solution freezes at 34 degrees below zero.
A solution composed of 60% water, 10% glycerine and 30% alcohol is commonly used, its freezing point being about 8 degrees below zero.
On account of evaporation fresh alcohol must be added frequently in order to maintain the proper solution.
| How are leaks and jams in the Radiator repaired? | Answer No. 41 |
A small leak may be temporarily repaired by applying brown soap or white lead—but the repair should be made permanent with solder as soon as possible. A jammed radiator tube is a more serious affair. While the stopping of one tube does not seriously interfere with the circulation, it is bound to cause trouble sooner or later—and the tube will freeze in cold weather. Cut the tube an inch above and below the jam and insert a new piece, soldering the connections. If the entire radiator is badly jammed or broken it would probably be advisable to install a new one.
