SLACK FAN BELT
OVERHEATING CAUSED There are many reasons for the engine .overheating, but it is obvious to any one that a radiator cannot act efficiently if air cannot pass freely through it. In many instances the cause of overheating may be a faulty fan or loose fan belt. On some cars the fan blades are made of sheet metal and are liable to become bent. If they lose their "set" they will not be capable of creating an air current strong enough to cool the engine. They should be examined occasionally, and if they appear to have flattened out they should be carefully reset to the original angle. Sometimes the fan pulley is fitted eccentrically on the shaft, and sometimes on an arm which can be adjusted. A popular modern idea is to run the,, dynamo from the fan belt, the position of the dynamo being made adjustable in order to alter the tension of the belt. A "V" belt should not be run too tightly, or it will soon wear out. Only the sides of the "V" should touch the flanges of the pulley, and the belt should not bed down on to the hub of the pulley itself. A belt which is found to be bedded down should be renewed, as it is probably badly worn.
