What antifreeze to use in a Suzuki SX4 Crossover?

Answer 1

Copy / paste from the 2008 service manual (for the SX4 produced in Hungary):

The cooling system has been filled with a quality coolant

that is a 50/50 mixture of water and ethylene glycol

antifreeze.

This 50/50 mixture coolant solution provides freezing

protection to -36 °C (-33 °F).

• Maintain cooling system freeze protection at -36 °C (-

33 °F) to ensure protection against corrosion and loss

of coolant from boiling. This should be done even if

freezing temperatures are not expected.

• Add ethylene glycol base coolant when coolant has to

be added because of coolant loss or to provide added

protection against freezing at temperature lower than

-36 °C (-33 °F).

NOTE

• Alcohol or methanol base coolant or plain

water alone should not be used in cooling

system at any time as damage to cooling

system could occur.

• Coolant must be mixed with demineralized

water or distilled water.
