SEQUENCE OF WORKS
1. To relieve pressure in the cooling system, open the expansion tank cap. Be careful when working on a hot engine - there is a risk of getting burned!
2. Place a clean container under the radiator and loosen the clamp securing the lower radiator hose or unscrew the plug on the lower radiator tank.
3. To help the coolant drain better, remove the cap from the expansion tank. Drain the coolant and cover the container with the drained liquid.
4. Install the lower radiator hose and secure it with a clamp (use a new clamp if necessary). Tighten the drain plug securely.
5. Fill the expansion tank with the prescribed coolant. Fill the remaining amount (approximately 2 mm to the upper mark) with soft water, if possible, until air bubbles stop appearing.
6. Start the engine and let it run at medium crankshaft speed until the thermostat opens. If necessary, add tap water to the expansion tank. The level in the expansion tank should remain constant when the engine is warm.
7. Close the expansion tank cap and perform a test drive to remove air from the coolant.
8. After a test drive, carefully remove the expansion tank cap and let the engine run at medium crankshaft speed until the radiator fan switches off.
9. Check the level and, if necessary, add tap water up to the upper mark of the expansion tank.
10. Close the expansion tank cap.
