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.
