- NOTICE:
- Make sure that the V belt is properly set to each pulley.
After installing the belt, check that it fits properly in the ribbed grooves.
| *a | CORRECT |
| *b | INCORRECT |
- HINT:
- Make sure to check by hand that the belt has not slipped out of the grooves on the bottom of the pulley.
| 6. INSTALL FRONT FENDER APRON SEAL LH |

- NOTICE:
| 8. WARM UP ENGINE |
Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.
- NOTICE:
- Be sure to warm up the compressor when turning the A/C switch is on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
| 9. CHECK FOR REFRIGERANT GAS LEAK |
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under these conditions:
Using a halogen 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 halogen leak detector sensor into the unit and perform the test.
Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
| 10. INSTALL UPPER RADIATOR SUPPORT SEAL |
Install the radiator support seal with the 7 clips.
