Cooling system, filling and bleeding
| Cooling system, filling and bleeding |
Instruction: use only antifreeze specified in the technical data, Cooling system and make sure the concentration is 50% water and 50% antifreeze. Antifreeze is not only used to protect the entire cooling system from freezing, it is also designed to protect all the components that the coolant comes in contact with from corrosion/lime deposits. Therefore, it is recommended to use antifreeze even in tropical climates.
Besides the concentration, the water quality also plays an important role. Freshwater that can be used for drinking normally fulfils the quality requirements. Regenerated seawater does not possess the required quality! Damage to the engine can also arise from the use of antifreeze that has not being approved!
When changing the radiator, cylinder head or cylinder head gasket, the old coolant must not be reused!
Important: cars with air-conditioning: turn of the air-conditioning. Cars with ECC: set to ECO mode (if available)

Start the engine and leave it running
Instruction: run engine with the following cycle 1x: 30 seconds - 2000 rpm to 2500 rpm, 5 seconds idling, 30 seconds - 2000 rpm to 2500 rpm. Warm up the engine and idling speed until the radiator fan stage 1 cuts in. Run the engine with the above cycle 1 more time. The cooling system will be bled while the engine is warming up. |
