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 ...

Tachometer
The tachometer shows the engine speed in revolutions per minute (r/min, rpm). On the right side of the tachometer face is a portion called the “red zone”. Engine r/min (rpm) in the red zone is above maximum recommended engine speed and is also above the range for good performance. ...

Spring Preload Adjustment
The spring preload adjuster is located at the lower end of each front fork leg and can be adjusted. To increase spring preload and stiffen the suspension, turn the preload adjuster clockwise with a hexagon wrench. To decrease preload and soften the suspension, turn the preload adjust ...
