change) procedure for filling with engine coolant.
1. Make sure that the engine is cool.
2. Open radiator cap pour coolant up to filler neck.
3. Pour coolant into reservoir tank up to “MAX” line.
4. Tighten radiator cap and start the engine. After
idling for 2 to 3 minutes, stop the engine and
reopen radiator cap. If the water level is lower,
replenish.
WARNING: WHEN THE COOLANT IS HEATED TO A
HIGH TEMPERATURE, BE SURE NOT TO LOOSEN
OR REMOVE THE RADIATOR CAP. OTHERWISE YOU
MIGHT GET SCALDED BY HOT VAPOR OR BOILING
WATER. TO OPEN THE RADIATOR CAP, PUT A
PIECE OF THICK CLOTH ON THE CAP AND LOOSEN
THE CAP SLOWLY TO REDUCE THE PRESSURE
WHEN THE COOLANT HAS BECOME COOLER.
5. After tightening radiator cap, warm up the engine
at about 2000 rpm. Set heater adjustment to the
highest temperature position, and let the coolant
circulate also into heater water system.
6. Check to see the thermostat has opened through
the needle position of water thermometer,
conduct a 5–minute idling again and stop the
engine.
7. When the engine has been cooled, check filler
neck for water level and replenish if required.
Should extreme shortage of coolant is found,
check the cooling system and reservoir tank hose
for leakage.
8. Pour coolant into reservoir tank up tp “MAX” line.

When working on the fuel system, there are several
things to keep in mind:
Any time the fuel system is being worked on,
disconnect the negative battery cable except for
those tests where battery voltage is required.
Always keep a dry chemical (Class B) fire
extinguisher near the work area.
Replace all pipes with the same pipe and fittings that
were removed.
Clean and inspect “O” rings. Replace if required.
Always relieve the line pressure before servicing any
fuel system components.
Do not attempt repairs on the fuel system until you
have read the instructions and checked the pictures
relating to that repair.
