  Q: Should the fan belt and air pump drive belt be checked for wear and tension, and how should their tension be adjusted on Mazda B2000?

  A:

  The fan belt is also to be examined concerning wear and tension as proposed in the Maintenance Interval charts. In case of wearing, cracking, or fraying of the part of the belt, it should be changed to the new one. To check belt tension, press thumb half way between pulleys (approximately 22 lbs. pressure) to fan belt and check deflection, should be approximately 3/8 in. on new belts and 1/2 in. on used belts. In order to alter the tension, it is recommended to loosen the mounting bolt, the adjusting bolt of the alternator, and then relocate the alternator until one attains the desired tension before tightening the bolts again and checking the tension. In the case of the air pump, it is important to test the tension of the drive belt by placing a thumb force between air pump pulley and crankshaft pulley with an aim of deflecting 1/2-5/8 in. In case of tension being wrong, slowly loosen the mounting and fitting bolts, force the air pump either outwards or inwards until the required deflection is secured and then tighten the bolts to 22 ft. lbs. The fan belt, air pump belt and other belts must also be inspected on their tension and wear and in case of either being worn, frayed or broken, then it must be replaced. To ensure that the belt is checked and adjusted, press the belt in the midpoint between the pulleys using the thumb pressure (approximately 22 lbs.), and make sure that there is a deflection of 3/8-1/2 in. In case of the fan belt, loosen the bolts that hold the alternator in place, position the alternator to get the required tension, attach the bolts, and again test the tension. In the case of the air pump drive belt, the mounting and adjusting bolts should be loosened by turning them, the air pump should be moved until the appropriate tension is attained, and the bolts should be tightened followed by checking the tension.
