6 DO-IT-YOURSELFMAINTENANCE 22 Drive belts should be checked periodically for proper tension. At the same time, belts should be examined for cracks, wear, fraying or other evidence of deterioration and replaced if necessary. When a new belt is replaced, the belt should be located within the pulley of flat idler. Belt routing should also be checked to be sure there is no interference between the belts and other parts of the engine. CHECKING AND REPLACING FUSES G200A01A-AAT Replacing a Fusible Link ! CAUTION: When replacing a fusible link, never use anything but a new fusible link with the same or lower amperage rating. Never use a piece of wire or a higher-rated fusible link. This could result in serious damage and create a fire hazard. NOTE: Drive belt tension is adjusted automatically by the auto tensioner. HNF4004 A fusible link will melt if the electrical circuits from the battery are ever overloaded, thus preventing damage to the entire wiring harness. (This could be caused by a short in the system drawing too much current.) If this ever happens, have a Hyundai dealer determine the cause, repair the system and replace the fusible link. The fusible links are located in a relay box in the engine compartment for easy inspection.
