Cooling System: Service and Repair
Routine MaintenanceWARNING: Do not remove the filler cap when engine is hot because the cooling system is pressurized and personal scalding could result.
CHECK/TOP UP COOLING SYSTEM
- To prevent corrosion of the aluminium alloy engine parts it is imperative that the 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.
- When removing the filler cap, first turn it counter-clockwise a quarter of a turn and allow all pressure to escape, before turning further in the same direction to lift it off.
- With a cold engine, the correct coolant level should be up to the 'Water Level' plate situated inside the expansion tank below the filler neck.
NOTE: The water level plate on later models has been deleted from the expansion tank, therefore the coolant should be filled to the top of the sensor float which is approximately 25 mm (1.00 inch) below the filler neck.
- If necessary, top up the cooling system with premixed coolant. Use soft water whenever possible, if local water supply is hard, rainwater should be used.
- When replacing the filler cap it is important that it is tightened down fully. Failure to tighten the filler cap properly may result in water loss, with possible damage to the engine through over-heating.
- Check cooling/heater systems for leaks and hoses for security and condition.
- Cooling system hoses should be changed at the first signs of deterioration.
- The cooling system should be drained and flushed at 2 year intervals or at the onset of the second winter.
