Radiator and Radiator Fan Removal
- Drain the coolant (See Coolant Change in the Periodic Maintenance chapter).
- Remove the left front frame cover (See Front Frame Cover Removal in the Frame chapter).
- Open the clamp [A].
- Disconnect the radiator fan lead connector [B].
- Remove the radiator hose [C].

Remove:
- Radiator Hose [A]
- Reserve Tank Hose [B]
- Radiator Bolt [C]

- Pull [A] the radiator [B] toward the left, noting the baffle plate [C] on the cylinder head cover.
Caution: Do not touch the radiator core. This could damage the radiator fins, resulting in loss of cooling efficiency.

Remove:
- Radiator Fan Mounting Bolts [A]
- Radiator Fan [B]

Radiator and Radiator Fan Installation
If the radiator guard [A] was removed, install it.
- Install the radiator fan [B].
- Install the rubber dampers [C] and collar [D] to the radiator and frame.
- Align the projections [E] on the frame with the holes [F] on the dampers.
Note the baffle plate on the cylinder head cover when installing the radiator.
Tighten:
Torque - Radiator Bolt: 15 Nbm (1.5 kgf·m, 11 ft·lb)
- Position the reserve tank hose clamp [G] so that its pinch heads faces downward.
- Install the radiator hose clamps [H] as shown.
Torque - Radiator Hose Clamp Screws: 2.0 Nm (0.20 kgf·m, 18 in·lb)
- Fill the radiator with the coolant (See Coolant Change in the Periodic Maintenance chapter).

Radiator Inspection
- Remove the radiator (See Radiator and Radiator Fan Removal).
- Check the radiator core.
If there are obstructions to air flow, remove them.
If the corrugated fins [A] are deformed, carefully straighten them.
If the air passages of the radiator core are blocked more than 20% by unremovable obstructions or irreparably deformed fins, replace the radiator with a new one.

Caution: When cleaning the radiator with steam cleaner, be careful of the following to prevent radiator damage: Keep the steam gun [A] away more than 0.5 m (1.6 ft) [B] from the radiator core.
Hold the steam gun perpendicular [C] (not oblique [D]) to the core surface.
Run the steam gun, following the core fin direction.

Radiator Cap Inspection
- Remove the radiator cap (See Coolant Change in the Periodic Maintenance chapter).
- Check the condition of the bottom [A] and top [B] valve seals and valve spring [C].
If any one of them shows visible damage, replace the cap with a new one.

- Install the cap [A] on a cooling system pressure tester [B].
Note: Wet the cap sealing surfaces with water or coolant to prevent pressure leaks.
- Watching the pressure gauge, pump the pressure tester to build up the pressure until the relief valve opens: the gauge needle flicks downward. Stop pumping and measure leak time at once. The relief valve must open within the specified range in the table below and the gauge hand must remain within the same range at least 6 seconds.
Radiator Cap Relief Pressure
Standard: 93.3-122.7 kPa (0.95-1.25 kgf/cm², 13.5-17.8 psi)
If the cap can not hold the specified pressure or if it holds too much pressure, replace it with a new one.

Radiator Filler Neck Inspection
- Remove the radiator cap (See Coolant Change in the Periodic Maintenance chapter).
- Check the radiator filler neck for signs of damage.
- Check the condition of the top and bottom sealing seats [A] in the filler neck. They must be smooth and clean for the radiator cap to function properly.
