Kawasaki Ninja Service Manual: Pressure Testing

Kawasaki Ninja Service Manual / Cooling System / Coolant / Pressure Testing

Remove the radiator cap in two steps. First turn the cap counterclockwise to the first stop. Then push and turn it further in the same direction and remove the cap.

Pressure Testing


NOTE

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

Pressure Testing


NOTICE

During pressure testing, do not exceed the pressure for which the system is designed. The maximum pressure is 142 kPa (1.45 kgf/cm², 21 psi).

If the pressure holds steady, the system is all right.

If the pressure drops and no external source is found, check for internal leaks. Droplets in the engine oil indicate internal leakage. Check the cylinder head gasket and the water pump.

Remove the pressure tester, replenish the coolant, and install the radiator cap.

Coolant Deterioration Inspection
Remove the right lower fairing (see Lower Fairing Removal in the Frame chapter). Visually inspect the coolant in the reserve tank [A]. If whitish cotton-like wafts are observed, aluminum par ...

Cooling System Flushing

Oxygen Sensor Installation (Equipped Models)
NOTICE Never drop the oxygen sensor [A] especially on a hard surface. Such a shock to the unit can damage it. Do not touch the sensing part [B] to prevent oil contact. Oil contamination from hands can reduce sensor performance. Tighten: Torque - Oxygen Sensor: 25 N·m (2.5 kgf·m, 18 ...

Armature Inspection
Using the × 1 Ω hand tester range, measure the resistance between any two commutator segments [A]. Special Tool - Hand Tester: 57001-1394 If there is a high resistance or no reading (∞) between any two segments, a winding is open and the starter motor must be replaced. ...
