ti-freeze protection must be guaranteed down to at least
-25°C.
♦ The temperature reading on the refractometer corresponds
to the »ice flocculation point«. Flakes of ice may start form‐
ing in the coolant below this temperature.
♦ Do not reuse old coolant.
♦ Use only a water/coolant additive mixture as a slip agent for
coolant hoses.
4.23.1 Anti-freeze protection: checking, re‐
plenishing coolant additive if necessary
Special tools and workshop equipment required
♦ Refractometer -T10007A-
♦ Refractometer -T10007B-
Note
Read precise value for the following tests at light-dark border.
Using a pipette, place a drop of water on the glass to improve
the readability of the light-dark border. The light-dark border can
be clearly recognised on the “WATERLINE”.
– Check concentration of coolant additive using refractometer
(refer to operating instructions).
Scale -1- of the refractometer is calibrated for the coolant addi‐
tives G12++ and G12evo.
Scale -2- of the refractometer is calibrated for the coolant addi‐
tive G13.
– If anti-freeze protection is insufficient, drain some coolant
and top up with coolant additive ⇒ page 49 .
