Freeze Protection, Checking And Adding Coolant Additive If Necessary

Special tools and workshop equipment required

Refractometer :T10007A
Refractometer :T10007B

NOTE:

The cut-off line can be read to obtain an accurate reading for the following tests. Place a drop of water on the glass using a pipette to improve the readability of the cut-off line. The cut-off line is now clearly recognizable on the "WATERLINE".

-- Check the coolant additive concentration using the Refractometer (observe the operating instructions).

The scale -1- on the refractometer refers to the G12++ and G12evo coolant additives.

The scale -2- on the refractometer refers to the G13 coolant additive.

-- Drain some of the coolant and add coolant additive if the freeze protection is inadequate. Refer to COOLANT LEVEL, CHECKING AND FILLING IF NECESSARY .

NOTE:

If it cannot clearly determined which coolant additive is in the coolant system, use the scale -2- for coolant additive G13.

Please follow all waste disposal regulations!

-- Check the concentration of the coolant additive again after the road test.
