Coolant: Description and Operation




Coolant Description

The coolant recovery system is a standard system, which allows part of coolant to flow from the radiator into the coolant reservoir when it is expanded by heat. When the cooling system cools down, the coolant in the coolant reservoir is drawn back into the radiator.

The cooling system has been filled with a SUZUKI super long life coolant (coolant color: Blue) that is a 50/50 mixture of ethylene glycol antifreeze and deionized water. This coolant solution provides freezing protection to -36 °C (-33 °F).

- Freeze protection down to -36 °C (-33 °F) is also important to ensure protection against corrosion and loss of coolant from boiling. This level of protection should be maintained even if freezing temperatures are not expected.

NOTE:

Using alcohol or methanol base coolant or plain water alone may cause damage to the cooling system.

Be sure to use the specified coolant.

NOTE:

- SUZUKI super long life coolant (coolant color: Blue) as supply part is diluted to the 50 percentage with deionized water. Use it as it is without diluting.
- Any treatment on SUZUKI super long life coolant (coolant color: Blue) shown below reduces its durability (maintenance interval) and should be avoided. However, if any of the following cases applies, follow the maintenance schedule of SUZUKI long life coolant (coolant color: Green):

- When the SUZUKI super long life coolant (coolant color: Blue) is diluted with water other than deionized water.
- When the SUZUKI super long life coolant (coolant color: Blue) is mixed with a SUZUKI long life coolant (coolant color: Green).

- Do not flush the cooling system. Doing so may cause new coolant to become diluted by the water remaining in the system. (The cooling system filled with the SUZUKI super long life coolant (coolant color: Blue) needs no flushing.)
