| 6. INSTALL V-RIBBED BELT |
Install the V-ribbed belt.
While turning the belt tensioner counterclockwise, remove the bar.
- NOTICE:
After installing the V-ribbed belt, check that it fits properly in the ribbed grooves. Check to confirm that the belt has not slipped out of the grooves on the bottom of the crank pulley by hand.
After installing a new belt, run the engine for approximately 5 minutes and then recheck the tension.
If it is difficult to install the V-ribbed belt, perform the following procedure.
Put the V-ribbed belt on every part except the tensioner pulley as shown in the illustration.
While releasing the belt tension by turning the belt tensioner counterclockwise, put the V-ribbed belt on the tensioner pulley.

Warm up the engine at less than 1,850 rpm for 2 minutes or more after charging the refrigerant.
- NOTICE:
- Be sure to warm up the compressor when turning the A/C switch ON after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
| 12. CHECK FOR LEAKAGE OF REFRIGERANT |
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under the following conditions:
Using a gas leak detector, check the refrigerant line for leakage.
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the gas leak detector sensor into the unit and perform the test.
Disconnect the connector and leave the pressure switch on for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
| 13. INSTALL COOL AIR INTAKE DUCT SEAL |
Install the intake duct seal with the 11 clips.
