6.6 Replacing Components
(1) Changing coolant
Stand the pump in a vertical position, and unplug "Coolant drain hole" (shown
in Fig. 20c) and "Air vent & full level check hole" (shown in Figs. 7c and 8c).
Drain all the coolant from "Coolant drain hole".
Inspect the coolant for contamination. If the coolant contains much pumped
liquid, the mechanical seal must be replaced.
After the coolant has been inspected, pour coolant (30%: Propylene glycol,
70%: Water) through "Coolant supply hole", until the coolant overflows from
"Air vent & full level check hole", and tighten the plugs. (Refer to *ICS opt.
