STARTING FROM COLD

NEW CARS USE THERMOSTAT When it is started it takes some time to warffi up, because of the low temperature of the water in the circulating system. In many new models now coming on to the market, however, an ingenious device, known as the thermostat, is built into the inlet of the radiator. Its function is to block the water circulating until the engine temperature reaches a certain heat, when the thermostat autimatically opens and allows the cooling system to operate. When the car is parked after driving the thermostat closes and prevents water circulation, keeping the engine warm for a long time. The engine can thus be started very easily without excessive use of the choke.

OVER THE SLEEPERS Motor transport is triumphing over trams and trains in many countries, but cars can really claim to be “putting it over” in England. There, four miles of double track were built by a railway company some time ago, and never used. Now, arrangements are being made to lease the track, cover it with concrete, and use ! it as a speedway and for club speed i trials. Banks on eAch side will act as | grandstands.

the petrol and solder up the hole. The hole is so small that it cannot be seen by the naked eye; also the petrol oozes through so slowly that it evaporates as it comes through, so that nothing is showing, and the location of the leak is difficult. The old method of finding out the hole or puncture is still the best. The float should be submerged in hot water. The heat vaporises any petrol in the float, sets up an internal pressure, and the resultant petrol gas bubbles through the hole and up through the water. The location of the hole is thus simple. The float should be kept submerged in the warm water till all the bubbling ceases. It will then be clear of petrol, which will have all been evaporated and forced through the leak. The float should be dried and allowed to rest, so that it can become filled with air again at atmospheric pressure. Then the hole should be most carefully 1 soldered up with soft solder, using a I small soldering iron and scraping I ■ I away the superfluous solder, so as not ] ■ to increase the weight of the float. j
