2. INSPECTION AND ADJUSTMENT 2.2.6 Inspection every 1,000 hours or one year Be sure to check the following points every 1,000 hours or one year operation, whichever comes first. (1) Cooling water replacement Cooling water contaminated with rust or water scale reduces the cooling effect. Even when antifreeze agent (LLC) is mixed, the cooling water gets contaminated due to deteriorated ingredients. Replace the cooling water at least once a year. Beware of scald- ing by hot water Wait until the tempera- ture goes down before draining the cooling water. Otherwise, hot water may splash to cause scalding. 1) Remove the radiator cap.
2) Loosen the drain plug at the lower portion of the radiator and drain the cooling water. 3) After draining the cooling water, tighten the drain plug. 4) Fill radiator and engine with cooling water. a) Before filling, check to be sure the drain plug is closed. b) Remove the radiator cap of the radiator by turnig the radiator cap counter-clockwise about 1/3 of a turn. c) Pour the cooling water slowly into the radiator up to the lip of the filler port so that air bubbles do not develop. d) After supplying the cooling water, surely tighten the radiator cap.
To fasten the radiator cap, align the detentes on the back face of the radiator cap with the slot of the filler port and turn clockwise pushing it downward approx. 1/3 of a turn until contact with each other. e) Remove the cap of the coolant recovery tank, supply the cooling water to the FULL mark and fasten the cap. f) Check the rubber hose connecting the coolant recovery tank to the radiator. Be sure the rubber is securely connected and there is no looseness or damage. When the rubber hose is not water tight, an excessive amount of cooling water will be consumed. 82E-5 – 98E-5 SERIES 2-17 No.
