Kawasaki Ninja Service Manual / Periodic Maintenance / Periodic Maintenance Procedures / Replacement Parts / Coolant Change

WARNING

Coolant can be extremely hot and cause severe burns, is toxic and very slippery. Do not remove the radiator cap or attempt to change the coolant when the engine is hot; allow it cool completely.

Immediately wipe any spilled coolant from tires, frame, engine or other painted parts. Do not ingest coolant.

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.

NOTE

Pour in the coolant slowly so that it can expel the air from the engine and radiator.

NOTICE

Soft or distilled water must be used with the antifreeze (see below for antifreeze) in the cooling system.

If hard water is used in the system, it causes scales accumulation in the water passages, and considerably reduces the efficiency of the cooling system.

Water and Coolant Mixture Ratio (Recommended)

Soft Water: 50%

Coolant: 50%

Freezing Point: –35°C (–31°F)

Total Amount: 2.6 L (2.7 US qt)

NOTE

Choose a suitable mixture ratio by referring to the coolant manufacturer’s directions.

Start the engine with the radiator cap removed and run it until no more air bubbles [A] can be seen in the coolant.

Tap the radiator hoses to force any air bubbles caught inside.

Stop the engine and add coolant up to the radiator filler neck.

If the coolant level is lower than the “L” level line, add coolant to the “F” level line (see Coolant Level Inspection).
