    Inspection

    
    
    

    Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

    Removal & Installation

    
    
    

    1. Disconnect the negative battery cable.
    2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.

    
    

    To install:

    1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley - A/C pulley - idler pulley - generator pulley - water pump pulley - P/S pump pulley - tensioner pulley.
    2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
    3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

          1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
          2. Remove the engine cover. Discharge the air conditioning system. Record the radio anti theft code data. Relieve the fuel system fuel pressure.
          3. Disconnect the negative battery terminal. Disconnect the positive battery terminal. Remove the battery from the vehicle.
          4. Remove the air intake hose and air cleaner assembly.
          5. Disconnect the MAF electrical connector. Disconnect the breather hose from the air cleaner hose. Remove the intake air hose and air cleaner assembly. Remove the battery tray.
          6. Remove the radiator grille upper cover. Disconnect the left and right oxygen sensor connectors.
          7. Drain the cooling system. Remove the upper and lower radiator hoses. Disconnect and plug the automatic transaxle fluid lines.
          8. Disconnect the high and low pressure pipes from the radiator and compressor.
          9. Disconnect the engine wiring harness. Remove the engine underhood fuse and relay box. Disconnect the FAM connectors.
          10. Unscrew the FAM mounting bolts and remove the FAM from the splash shield.
          11. Disconnect the transaxle wire harness connector and remove the transaxle control cable. Disconnect and remove the heater hoses.
          12. Remove the brake vacuum hose. Remove the upper power steering hose.
          13. Raise and support the vehicle safely. Remove the front tires and wheels.
          14. Remove the radiator grille upper cover, for convenience.
          15. Disconnect the power steering return hose. Remove the radiator support upper member, for convenience.
              
              NOTE

          To install:

          1. Installation is the reverse of the removal procedure.
          2. Adjust the shift cable. Fill the engine and transaxle to specification with the proper fluids.
          3. Before starting the engine turn the ignition switch to the RUN position so that the fuel pump runs for approximately two seconds and the fuel line pressurizes.
          4. Reprogram the radio anti theft code data.
          5. Repeat the operation two or three more times, than check for fuel leakage.
