z Since P158LE/P180LE/P222LE/PU158TI/PU180TI/PU222TI cylinder liner is wet type, particularly
the cooling water control should be applied thoroughly.
z The density of antifreezing solution and additive for rust prevention is able to be confirmed by the
cooling water test kit (Fleetguard CC2602M)
z How to use the cooling water test kit
(1) When the cooling water temp. of engine is in the range of 10 ~ 55 ° C, loosen the plug for
cooling water discharge and fill the plastic cup about a half.
NOTE :
In taking the cooling water sample, if the water in auxiliary tank were taken, it is hard
to measure the accurate density. Take the cooling water sample necessarily
loosening the cooling water discharge plug.
(2) At the state of a test paper soaked in the sampled water, after taking the paper out through
water agitation, shake off the water.
(3) Wait for about 45 sec. till the color change of test paper.
NOTE :
However, it should not elapse longer than 75 sec, and if it did, the hue would change.
(4) Make the numerical value by comparing the test paper which hue has changed with the color
list of label on storage bottle.
(5) By comparing the hue changed into yellowish green or so with the green color indication of test
paper storage bottle, confirm the density. (Then, the density indication must be in the hue range
of 33 % to 50 %).
(6) The brown at the middle of test paper and the lower pink color indication represent the additive
state for rust prevention, and the proper range is that the meeting numerical value of brown
(vertical) and pink color (horizontal) locates in the range of 0.3 to 0.8 at the color list of label on
the test paper storage bottle.
(7) In case of less than 0.3, replenish the additive for rust prevention (DCA4), and in case of more
than 0.8, pour out the cooling water about 50 % and then readjust the density after refilling with
clean fresh water.
