Cooling water

Check for a steady flow of water from the
cooling water pilot hole. A continuous flow of
water from the cooling water pilot hole shows
that the water pump is pumping water
through the cooling water passages.
TIP:
When the engine is started, there may be a
slight delay before water flows from the cool-
ing water pilot hole.

EMU41234

Procedure for warming up engine

1. After starting the engine, warm up the
engine until the engine speed stabilizes
at idle speed to provide maximum oper-
ating performance and acceleration.
NOTICE: Failure to do so will shorten
engine life.
Idle speed (in neutral):
700–800 r/min
2. Check that the low oil pressure-alert indi-
cator remains off. NOTICE: If the low oil
pressure-alert indicator blinks after
the engine starts, stop the engine.
