Coolant Colour

Don’t pay too much attention to the colour of the coolant, it doesn’t necessarily tell you what it is made from (propylene glycol, ethylene glycol etc). It is recommended that you top up with the same type coolant but if you bought the car new, you won’t know what was used. As long as you select a coolant from the list below, you will be ok to top your system up with it.

If you have drained the system and flushed it out, you can replace the coolant with which ever type you like as long as it is compatable with aluminium.

Warning

Do not leave the collected coolant in an open container that can be accessed by animals, the antifreeze is sweet and many pets have died drinking it.

Coolant Specs

The coolant composition must be a 50:50 ratio (half and half). Half coolant, half water.
The coolant contains antifreeze and anticorrosion agents and should conform
to specification sheet number MB325.0 or premixed coolant spec sheet MB326.0

Generally, standard drinking water is fine to use as long as you don’t live in a hard water area.
If you do, consider using distilled water available from most car shops or bottled water from a supermarket.
