Inspection, Maintenance and Adjustment

A.
Check antifreeze concentration levels by
comparing the color change at the end of test
paper, with the green spectrum range, with the
green symbol on the upper portion of the
container bottle.
NOTE:
A suitable concentration indicator should
be between 33% and 50%).
B.
Check the anticorrosive additives, by comparing
brown color in the middle range of the test strip
and pink color on the lower part of the test strip,
with the brown and pink spectrum range. Where
the brown (vertical) color and pink (horizontal)
color intersects represents the anticorrosive
additive level.
NOTE:
A reading between 0.3 and 0.8, represents
an adequate additive level.
5.
Correct the antifreeze concentration and additive levels.
A.
If anticorrosive additive level is below 0.3, add
100% pure antifreeze to the radiator.
B.
If anticorrosive additive level is greater 0.8, add a
50% distilled water and antifreeze mixture to lower
the additive reading.
NOTE:
In either case keep the antifreeze concentration
level between 33% and 50%.
6.
Run the engine to recirculate the coolant mixture. Be
sure that engine reaches operating temperature to
ensure a thorough mix. Shut down engine and retest
antifreeze.
NOTE:
When making adjustment, drain 1 liter (1 U.S.
quart) of coolant from the radiator. Add 30 cc (1
fl oz) at a time to the drained fluid. Keep track of
how many cc's (fl oz's) were added to the 1 liter
(1 U.S. quart) to obtain a proper reading. Then
multiply that number times the total system
capacity of liters (U.S. quarts). Add that amount
to the radiator.
Example: If 1 liter needs 90 cc to obtain proper
reading. Then system capacity of 40
liters x 90 cc = 3,600 cc (3.6 liters) of
correction fluid.
