Freeze Protection, Checking And Adding Coolant Additive
Special Tools And Workshop Equipment Required
Read the cut-off line to obtain an accurate value 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 can be clearly recognized on the "WATERLINE".
-- Check the coolant additive concentration using the :T10007A . (Pay attention to the service/repair/system information).
The refractometer scale -1- is designed for coolant additives G12; G12 Plus, G12 Plus Plus and G11.
The scale -2- only applies to coolant additive G13.
-- Drain some of the coolant and add coolant additive if the freeze protection is inadequate. Refer to COOLANT LEVEL, CHECKING AND ADDING COOLANT ADDITIVE .
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.
