This statement from Car Care Council is based on a study by a major manufacturer of car coolâ€" ants involving about 1,200 cars. The results showed more than a third of the threeâ€"yearâ€"old models checked had products of corrosion in their coolants. The same survey showed that, on average, nearly half the cars checked needed some kind of coolâ€" ingâ€"system service: One year old: 35% ; two years The percentages were: One year old: 22%; two years old: 32% ; three years old: 36%. None of the cars‘checked was an "old" car. old: 49% ; three years old: ‘nw,m:.n h:s been hapâ€" pening is a fairly story: the need loum: more efficient cars has imâ€" posed a need for smalle: Bince engines work more efficiently and give more miles per gallon at higher rather than lower temperatures, designers have resorted to pressurâ€" ized systems in which the radiator cap plays a major role. So, too, does the kind of coolant used to transfer heat from the engine to the radiator where it can â€"be passed to the surroundâ€" ing air. . About a third of the heat produced by today‘s internalâ€"combustion en« gine must be taken away from the engine block and transferred safely to the outer air . . : this is the function of the cooling _ Knowing the correct tire size used to be the only criterion for purchas: To achieve performance comparable with that ofâ€" fered by the "standard" car of the past, designers have had to make today‘s engines work harder. And when an engine works harder, it generates more heat. * ing new rubber for a car. But the wide variety in tire construction, designaâ€" tion and ratings has made tire shopping somewhat more complicated. Never select a size smaller than those which came with the car. Tires of different size designaâ€" DANGER POINTS IN COOLING SYSTEM Many people don‘t know it, but aluminum is highly susceptible to corrosion damage. Aluminum corroâ€" sion gradually perforates tiny holes in the water pump, letting coolant leak away causing engine temperaâ€" tures to rocket.

Pay heed to size MURRAY BRUBACHER If a 50â€"50 mixture of water and a reliable brand of coolant is used in a system pressurized to about 15 pounds per square inch, the boiling point is raised to about 265°F (about 129°C) and the freezing is lowered to about â€"34°F (about â€"*36C) . Car Care Council points out that the old idea of & "permanent" coolant is obsolete. Certainly, a highâ€" quality coolant mixed with water in that 50â€"50 ratio will continue to provide protection against freezâ€" ing year after year. Howâ€" ever,, the higher engine temperatures of the modâ€" ern car will break down the corrosion inhibitors in the coolant much more quickly than in past years.
