Suzuki GSX-R 1000 Service Manual: Engine coolant recommendation

Engine coolant

Use an anti-freeze/engine coolant compatible with an aluminum radiator, mixed with distilled water only.

Water for mixing

Use distilled water only. Water other than distilled water can corrode and clog the aluminum radiator.

Anti-freeze / engine coolant

The engine coolant perform as a corrosion and rust inhibitor as well as anti-freeze. Therefore, the engine coolant should be used at all times even though the atmospheric temperature in your area does not go down to freezing point.

Suzuki recommends the use of suzuki coolant antifreeze/ engine coolant. If this is not available, use an equivalent which is compatible with an aluminum radiator.

Liquid amount of water / engine coolant

Solution capacity (total) 2 750 ml (2.9/2.4 Us/imp qt)

For engine coolant mixture information, refer to “engine coolant description” in section 1f .

Caution Mixing of anti-freeze/engine coolant should be limited to 60%. Mixing beyond it would reduce its efficiency. If the anti-freeze/engine coolant mixing ratio is below 50%, rust inhabiting performance is greatly reduced. Be sure to mix it above 50% even though the atmospheric temperature does not go down to the freezing point.
