Cooling water @ Regarding the cooling water that is to be used for engine, the soft water not the hard water must be used.
® The engine cooling water can be used diluting it with antifreezing solution 40% tive for rust prevention (DCA4) and the addi- 3 ~ 5 %. ®@ The density of above solution and additive must be inspected every 500 hours to maintain it properly. M Note : The proper density control of antifreezing solution and rust preventing additive will be able to prevent the rusting effectively and maintain the improper control might give the fatal damage the stable quality of engine. For to the cooling water pump and cylin- der liners, detail care is needed. ®@ Since D1146/PU086, D1146T/PUO86T and PO86TI cooling water control should cylinder liner is dry type, particularly the be applied thoroughly.
® The density of antifreezing solution and additive for rust prevention by the cooling water test kit. (Fleetguard CC2602M or DAEWOO is able to be confirmed 60.99901 -0038) ®@ 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. - 20-
