The tension of the accessory drive belt (Fig. 5.29) is checked by pressing a finger on the belt branch between the generator and water pump pulleys. When pressing with a force of 100 N (10 kgf), the belt deflection should be 4-6 mm. If the belt is loose, the automatic tensioner must be replaced. The poly V-belt should be replaced if any tears, cracks or abrasions are found on it. The power steering pump is driven from the water pump pulley.
