COOLING SYSTEM

COOLING SYSTEM 4-15

Radiator, Radiator Fan

NOTE

О Wet the cap sealing surfaces with water or coolant to prevent pressure leaks.

• Watching the pressure gauge, slowly pump the pressure
tester to build up the pressure. The relief valve must open
within the relief pressure range as shown below. The
gauge hand must remain at least 6 seconds between the
lowest relief pressure and the valve opened pressure.

Radiator Cap Relief Pressure Standard: 93-123 kPa (0.95-1.25 kgf/cm²,14-18 psi)

• If the cap cannot hold the specified pressure, or if it holds
too much pressure, replace it with a new one.

Radiator Hose and Connection Inspection

• Refer to the Radiator Hoses and Connections Inspection
in the Periodic Maintenance chapter.

Radiator Hose, Pipe, Air Vent Hose, Reservoir Tank Hose Installation

• Install the radiator hoses. Avoid sharp bending, kinking, flattening, or twisting.

• Tighten the hose clamps securely.

Torque - Radiator Hose Clamp Screws: 2.5 N-m (0.25 kgf-m, 22 in-lb)

• Route the air vent hose, radiator hoses, pipes and reser­
voir tank hose (see Cable, Wire, and Hose Routing in the
Appendix chapter).

Thermostat Removal Drain the coolant.

Remove the left lower fairing (see Lower Fairings Re­moval in the Frame chapter). Turn the handlebar to right side fully.

Remove the radiator filler mounting bolts [A]. Remove the thermostat housing mounting bolts [B], and pull the thermostat housing [C] to outside. Unscrew the thermostat housing bolts [D].

Pull out the thermostat [A].

Thermostat Installation

• Install the thermostat [A] into the thermostat housing so that the thermostat does not touch the water temperature switch [B] as shown.

• Be sure to install the O-ring on the thermostat housing cover. Fill the radiator with coolant.

Thermostat Inspection

• Remove the thermostat, and inspect the thermostat valve [A] at room temperature.

• If the valve is open, replace the valve with a new one.
