(135 C) and ensures for a better heat dissipation.
The coolant portion of the mixture must amount to at
least 40% (freeze protection to -13 F [-25 C])
and should not exceed 60% (freeze protection to -40
F [-40 C]). Otherwise the freeze protection will
be reduced and the cooling efficiency will be
worsened.
The freeze protection must be ensured to
approximately -13 F (-25 C).
Checking freeze protection and adding coolant additive if
necessary
Special tools, testers and auxiliary items required
Refractometer T10007
Note:
Read the bright/dark boundary to obtain an accurate
reading for the following tests. Place a drop of water
on the glass to improve the readability of the
bright/dark boundary. The bright/dark boundary can
be clearly recognized on the "WATERLINE" .
- Check the concentration of the coolant additive using
refractometer T10007 (operating instructions).
