Kawasaki Ninja Owners Manual: Information for Coolant

Kawasaki Ninja Owners Manual / Maintenance and adjustment / Cooling System / Coolant / Information for Coolant

To protect the cooling system (consisting of the aluminum engine and radiator) from rust and corrosion, the use of corrosion and rust inhibitor chemicals in the coolant is essential. If coolant containing corrosion and rust inhibitor chemicals are not used, over a period of time, the cooling system accumulates rust and scale in the water jacket and radiator. This will clog up the coolant passages, and considerably reduce the efficiency of the cooling system.

WARNING

Coolant containing corrosion inhibitors for aluminum engines and radiators include harmful chemicals for human body.

Drinking coolant can result in serious injury or death. Use coolant in accordance with the instructions of themanufacturer.

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

NOTICE

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

If the lowest ambient temperature encountered falls below the freezing point of water, use permanent antifreeze in the coolant to protect the cooling system against engine and radiator freeze -up, as well as from rust and corrosion.

Use a permanent type of antifreeze (soft water and ethylene glycol plus corrosion and rust inhibitor chemicals for aluminum engines and radiators) in the cooling system. On the mixture ratio of coolant, choose the suitable one referring to the relation between freezing point and strength directed on the container.

NOTICE

Permanent types of antifreeze on the market have anti-corrosion and anti-rust properties. When it is diluted excessively, it loses its anti-corrosion property. Dilute a permanent type of antifreeze in accordance with the instructions of the manufacturer.

NOTE

Coolant
Coolant absorbs excessive heat from the engine and transfers it to the air at the radiator. If the coolant level becomes low, the engine overheats and may suffer severe damage. Check the coolant ...

Coolant Level Inspection
Situate the motorcycle so that it is perpendicular to the ground. Check the coolant level through the coolant level gauge on the reserve tank located to the left of the engine. The cool ...

Swingarm Bearing, Sleeve Inspection
NOTICE Do not remove the bearings for inspection. Removal may damage them. Inspect the needle bearings [A] and ball bearing installed in the swingarm. The rollers and ball in a bearing normally wear very little, and wear is difficult to measure. Instead of measuring, visually inspec ...

Master Cylinder Inspection (Visual Inspection)
Remove the master cylinders (see Front/Rear Master Cylinder Removal). Disassemble the front and rear master cylinders (see Master Cylinder Rubber Parts Replacement in the Periodic Maintenance chapter). Check that there are no scratches, rust or pitting on the inner wall [A] of each ma ...

Radiator and Cooling Fan
Check the radiator fins for obstruction by insects or mud. Clean off any obstructions with a stream of low-pressure water. WARNINGThe cooling fan spins at high speed and can cause serious injuries. Keep your hands and clothing away from the cooling fan blades at all times. ...
