Disassembly
1. Remove the fan.
Note: The reverse screw is used to fix the fan. When removing or installing, rotate the screw in the opposite direction to the normal screw.

2. Remove the fan motor from the casing.
Assembly
Assembly is performed in the reverse order of disassembly.
Apply locking sealant and tighten the screw.
Checking the radiator cap (on models without air conditioning)
1. Pull the vacuum valve to open it and make sure it closes completely when released.
Make sure the radiator cap vacuum valve seat is free of dirt and damage.
Make sure that there are no abnormalities when opening and closing the vacuum valve.
2. Check the cap release pressure.
Standard: 78-98 kPa (0.8-1.0 kg/cm²)
Limit: 59 kPa (0.6 kg/cm²)
When connecting the radiator cap to the pump, apply water or engine coolant to the cap seal.
If the vacuum valve is abnormal or the opening pressure is not normal, replace the radiator cap.
Caution: When installing the radiator cap, thoroughly wipe the radiator neck and remove waxy deposits and foreign particles.
Checking the tank cap (on models with air conditioning)
Attach the adapter to the pump as shown in the picture on the right.
When connecting the reservoir cap to the pump, apply water or engine coolant to the cap seal.
Check the tank cap release pressure.
88 kPa (0.90 kg/cm²)
If engine coolant is leaking through the cap or there are signs of leakage, replace the reservoir cap.
Checking the cooling system hoses
Check that the hoses are connected correctly, that there are no leaks, cracks, chafing, wear, or looseness.
