Op. MA. 230.0 1 FILLING THE WATER SYSTEM
IMPORTANT
: Core must be token to protect alternator from water whenever working on cooling systems fitted close to this unit.
Two operations are involved
- Complete filling i roolir~g c~s~<,v, nvd bvolvr ,,ail ,
- Partial filling I roolir,p ~J~S/IW, oul~* 1
NOTES
Draining the radiator and the engine unit does not involve draining the heater unit.
- De-aeration of the system is only operative when the thermostat is open 1 v,rgiur wnnu J.
I. COMPLETE REFILLING 1. Remove
spare wheel
.
2. Open heater control to fullest extent ( inside
vehicle 1.
3. Unscrew the two bleed screws ( 1 ) and ( 2 ).
Place a tronsporent tube
200 mm in length
over each screw in order to ovoid the escape
of the liquid.
4. Disconnect the heater outlet hose and pour in
approximately 0.6 litre of cooling liquid.
Reconnect tube ( 4).
5. Fill remainder of circuit slowly through the
header tank and close bleed screws I 1) and
( 2) after releasing air
6. Remove transparent tubes ( 3) and close header
tank.

b) by replacing the header tank cap with a
flexible rocker-cover union
I V~~/7id<~S 2/ IU7h - ,
7. Run engine at approximately 2000 rpm until
electric fan (5) cut (5) in.
Then let the engine idle for about 10 mins.
Never open header tank cap while electric fan (5)
ore/is in operation.
Do not open bleed-screws ( 1 ) and (2) while engine
is running.
8. After releasing the air. water level should
stabilize in header tank. Level should be checked
when the engine is cold.
9. Fit the rubber covers cm the bleed-screws.
Replace spare wheel.
II. PARTIAL FILLING
Same operations as for total filling except that
the heater unit is not filled by outlet tube ( 3)
to the radiator.
111. FILLING AND DE-AERATING THE AUXILIARY
HEATER UNIT ON CX AMBULANCE VEHICLES
Before connecting the auxiliary heater unit water
system to the main system. the following must
be carried out :
- Fill up the auxiliary heater unit and its hoses
( with heater control open I with 1.6 litres
( 2.8 pts 1 of coolant liquid of the some type
as that used in the main
system.
- Connect all hoses. and tiqhten 011 hose clips.
-Stat engine. and wait for electric fan (5) to
to cut-in ( De-aeration time 1.’
- Check the operation of the auxilioly heater unit.
- WHEN THE ENGINE IS COLD, check the level,
and top up if necessary.
