Show CAR owners can easily avoid practically prac-tically all their winter motor troubles. The recipe has just been made public in a study prepared by automotive experts. It is the pre-winter pre-winter check-up of the car's cooling system. One of the most serious cold-weather cold-weather complaints that attack a cooling system can result, it appears, from a defective hose. Although the hose looks all right, the lining may have rotted. As the water races through, it carries pieces of this rubber rub-ber into the radiator, clogging the tubes. Old hose hardens, too, and the connections con-nections break. This break will cause air suction and, of course, the antifreeze anti-freeze will begin to leak out. Water mixed with air speeds up rust and corrosion faster than any other one factor. All joints and the seams of the radiator core should also be checked. Leaks are very tricky things to find. Rust and corrosion cut down the radiator's cooling capacity so much that the engine boils in its "hot spots". A thorough check-up and cleaning of the cooling system is the first step to be taken. The next one is to use an anti-freeze that will really keep rust and corrosion under control. The most effective inhibitors are more likely to be found in the permanent anti-freezes because their inhibitor! have to stand up during an entire winter's driving. They are not added to from time to time as in the case of alcohol solutions. But even a permanent anti-freeze the report warns, should be selected with an eye to getting the utmost in engineering experience in the combining com-bining of an anti-freeze and its inhibitors. inhi-bitors. One permanent anti-freeze has a record of successful use in 40,000,000 automobiles. In installing such a permanent anti-freeze care must be taken, the report points out, never to fill the radiator to the top. Plenty of room should be allowed for the solution to expand as it warms up. The engineers en-gineers advise that when the antifreeze anti-freeze is first put in, the engine should be run for a few minutes. This releases trapped air and mixes the solution thoroughly before the car ii exposed to freezing temperatures. |
