Show RETARDED SPARK IS INJURIOUS TO AUTO Overheated Condition Harmful tp Pistons, Cylinders and Other Parts of Engine. (By William H. Stewart, Jr., President Stewart Automobile School.) You have all seen the fellow who runs his "steaming," clanking car around town. It looks for all the world like a baby locomotive, but perhaps ha does not know that this overheated condition injures the pistons, cylinders, cylin-ders, bearings and all Internal parts of the engine. Shortly he learns this for himself after he has paid a big repair bill for information that could have been obtained from any Instruction Instruc-tion book. If you run the car with the spark retarded, the engine will overheat and carbonize. A similar effect Is caused by a crippled fan or an Impeded water flow. If your engine overheats it is advisable to stop Instantly and find the trouble. In an emergency a very wise thing to do Is to pour an abundance of oil into the crank case. Your'ez-haust Your'ez-haust will smoke, but the additional oil will offer protection to the inside of the engine until relief Is at hand. Clean the belt occasionally and rid It of the oil and gummy matter. Hitch up your garden hose and send its spray through the openings In the radiator, which probably is clogged with mud. Do this from the engine side of the radiator; otherwise you may short circuit cir-cuit the electric system. As a further precaution see that all hose connec-' tions are good and not partially closed on the Inside, thereby retarding the water flow. This closing, though very slight, will retard radiation and cause trouble. |
