Important: Use only antifreeze 19 40 650 (09 194 431) and ensure a concentration of 50% water to 50 % antifreeze. Antifreeze does not just prevent the cooling system from freezing up, it also protects all the components that are in contact with coolant from rust/limescale deposits. As a result, antifreeze should always be added, even in tropical countries. 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 gasket 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.
Remove
- 1. Open cooling system • Unscrew coolant compensation tank cap
- 2. Top up coolant • Coolant compensation tank – To marking KALT/COLD
Install
- 3. Close cooling system • Screw on coolant compensation tank cap
- 4. Allow engine to run • at idle speed until thermostat opens
Note. Cooling system bleeds itself during warm-up phase.
- 5. Switch off engine • Allow to cool
- 6. Check coolant level • Coolant compensation tank – To marking KALT/COLD – top up coolant if necessary
