Checking and Adjusting DCA4 Concentration
•
Initial Charge (when replacing coolant totally)
Replace the coolant filter and add the DCA4 liquid for re-
fill. Use coolant filter (WF-2076). One DCA65L unit is
equivalent to four DCA60L units. The sample combina-
tions of DCA65L and DCA60L are shown in the following
table. Appropriately combine both DCA65L and DCA60L
so that the required concentration can be obtained.

Replacing Coolant Filter --- every 500 hours
DCA4 deteriorates its function after being used for a
long time. Normally replace it every 500 hours. However,
when the DCA4 concentration is measured:
•
When the antifreeze or LLC concentration is 50%: If
over 3 units concentration is measured, no replace-
ment is required, allowing the replacement hour to
extend up to max. 1000 hours.
•
Checking Coolant Concentration
1. If a large quantity of coolant was added when repair-
ing the engine or radiator, check the coolant concen-
tration in accordance with Item 5 Inspection Proce-
dure in this manual and maintain the proper coolant
concentration. (If the total coolant was replaced, con-
duct the initial charge in accordance with Item above
on this page.)
2. The coolant concentration may be outside the speci-
fication according to operation conditions or due to an
unexpected failure. Then, it is recommendable to
check the concentration every 500 hours.
