Important: Only use 19 40 650 (09 194 431) anti-freeze and ensure a concentration of 50% water and 50% anti-freeze. The purpose of anti-freeze is not only to protect the entire cooling system against freezing but also to protect all coolant-affected parts against corrosion and lime deposit. For this reason, anti-freeze must be used even in tropical regions. The water quality also plays an important role in addition to the mix ratio. Water of drinkable quality usually meets these requirements. The quality of purified sea water is inadequate! If radiator, cylinder head or cylinder head seal have been replaced the old coolant must not be re-used. Damage may also be caused to the engine if unauthorised anti-freeze agent is used.
- 1. Open cooling system • Unscrew coolant compensation tank cap
- 2. Top up coolant • Coolant compensation tank – To marking KALT/COLD
- 3. Close cooling system • Close coolant compensation tank cap
- 4. Start engine and allow to run • Then allow engine to run for approx. 2 minutes at 2500 - 3000 rpm
Note. Allow engine to warm up to max. 2500 rpm to triger the thermostat (1st fan stage is switched on).
Note. Cooling system bleeds automatically during warm-up phase.
- 5. Switch off engine • Allow it to cool
- 6. Check coolant level. • Coolant compensation tank – To marking KALT/COLD – top up coolant if necessary
