c) Fill heat exchanger to the top of the filler neck and
replace cap. Press down firmly on filler cap and hand
tighten in a clockwise direction.
d) Run the engine for 5 minutes on no load (out of gear),
then stop the engine, release the filler neck pressure
cap to remove any air from the system, remove the
cap and check the level. Top up coolant to the filler
neck and replace the filler pressure cap.
e) Check the cooling system for leaks.
f) If a calorifier is fitted care must be taken to see that
this is also full of coolant and all the air is bleed from
the calorifier circuit. Please refer to points 4 & 5 within
'Calorifier Connection' on page 32.
g) Preferably with the vessel tied up, run the engine
on 1 / load (in gear) for 15 minutes, as the system

initially warms up excess engine coolant will be leaked
off from the overflow pipe into the bilge*. Stop the
engine and allow the engine to fully cool down before
removing the pressure cap and topping up the engine
coolant to 25 mm/1" below the filler neck.
*Subject to installation it maybe possble to place a drip
tray or container to catch coolant overflow.
h) Repeat (g) if engine coolant level is greater than 1
inch below the base of the filler neck when the engine
has cooled down top up to level to 1 inch below.
i) Check the cooling system for leaks.
j) Re-run the engine on
minutes, check for leaks and repeat (h) & (i).
IMPORTANT!
The engine thermostat starts to open at 71°C,
as a consequence the running temperature
should always be between 71 > 85°C.

k) Coolant should be drained off every 2 years and
replaced with a new solution.
NB: When draining the engine coolant system, ensure the
engine has cooled sufficiently to prevent scalding from hot
pressurised water. Prior to draining a cold engine, remove
the filler cap from the heat exchanger (please refer to
image 34) and then open the water drain tap (please
refer to image 33). This allows the water to drain freely
from the system.
NB Beta 60
NB Beta 60: Is not equipped with a coolant drain tap and
will require a engine oil cooler hose to be disconnected
in order to drain of the engine coolant. Either hose can be
disconnected. Please ensure they are reconnected before
refilling the engine coolant.
CAUTION!
TO AVOID PERSONAL INJURY:
Engine Coolant Pressure Cap
Removal of the pressure cap when the engine
is hot can cause severe injury from scalding hot
water under pressure, always allow the engine
to fully cool.
Using appropriate personal protective
equipment turn the cap anti-clockwise to the
stop, this allows pressure to be released. Then
press firmly down on the cap and continue to
turn anticlockwise to fully release the cap.
To re-fit the cap align its tangs with filler neck,
press down and firmly turn the cap clockwise
until it fully meets the stop position.
