MAINTENANCE
CHECK/TOP UP COOLING SYSTEM
1. To prevent corrosion of aluminium alloy engine
parts it is imperative that cooling system is filled
with a solution of water and phosphate free
anti-freeze, winter or summer. Never fill or top up
with plain water.
WARNING: Do not remove filler cap when
engine is hot because cooling system is
pressurised and personal scalding could
result.
2. When removing filler cap, turn cap slowly
anti-clockwise, pause and allow all pressure to
escape.
3. Continue to turn until cap is removed.
4. When engine is cold expansion tank coolant
should be level with top of indicator post, visible
inside tank through filler hole.
5. If necessary, top up cooling system with
premixed coolant. Use soft water whenever
possible, if local water supply is hard, rainwater
should be used.
6. When replacing filler cap it is important that it is
tightened down fully. Failure to tighten filler cap
properly may result in water loss, with possible
damage to engine
The cooling system should be drained and flushed at
2 year intervals or at onset of second winter. Refer to
Coolant Requirements.
