3) Loosen drain cock to drain engine coolant into
container.
NOTE:
Remove radiator cap so that engine coolant will
drain faster.

B: FILLING OF ENGINE COOLANT
1) Remove air vent plug from radiator.
B2M0301
2) Fill engine coolant into radiator up to filler neck
position.
B2M0135
3) Fill engine coolant into reservoir tank up to
upper level.
B2M0140
4) Attach radiator cap and reservoir tank cap prop-
erly.
5) Install air vent plug.
6) Warm-up engine completely for more than five
minutes at 2,000 to 3,000 rpm.
7) Stop engine and wait until temperature drops to
a safe level.
8) If engine coolant level drops in radiator, add
engine coolant to filler neck position.
9) If engine coolant level drops from upper level of
reservoir tank, add engine coolant to upper level.
10) Attach radiator cap and reservoir tank cap
properly.
