speed. This opens the heating valves.
Run engine and flush out engine cooling circuit with three or four
short bursts of throttle (approx. 4500 to 5000 rpm) (sealing cap
open). While doing so, do not run engine for longer than approx.
30 sec. to prevent coolant from heating up and expanding. If
coolant level in expansion tank drops during this, top up
expansion tank to the brim with coolant. Attach screw cover and
run engine to heat it up until thermostat opens.
Coolant level check
To check coolant level, allow engine to cool down; coolant
temperature may not exceed 30
°
C. If ambient temperature is
above 30
°
C, then allow engine to cool down at least to ambient
temperature.
Check coolant level, top up coolant if necessary until float (1) is in
line with top edge of expansion tank (2).
Note:
Tank mark indicates the fluid level at approx. 20
°
C.
