If oil enters the cooling circuit, e.g. due to a defective cylinder head gasket, the radiator and expansion tank must be removed after repairs and washed with normal cleaning agents. When doing so, observe the instructions of the manufacturer of the cleaning agent. After installing the radiator in place, it is necessary to fill the entire cooling system with hot water several times and drain it.
The liquid after washing must not be poured out. Follow its manufacturer's instructions. Local authorities should provide information on where such fluids can be disposed of.
Withdrawal
1. Remove the fan shroud, refer to Section Removal and installation of the fan/fan shroud.
2. Drain the coolant and dispose of it, refer to Section Coolant replacement.
3. Gasoline engine: Remove the intake air filter box, refer to Section Removal and installation of the engine air filter.
4. Disconnect the coolant hoses at the top and bottom of the radiator. To do this, use a small screwdriver to remove the fasteners of the quick couplings upwards, refer to Section Connecting and disconnecting the quick coupling.
5. Disconnect the level sensor cable from the bottom left of the radiator.
6. Turn out at the left above at a radiator the screw -1-.
7. Tilt the heatsink back at the top, then lift it up out of the bottom holders.
The power steering and air conditioner radiators are located in front of the engine radiator in the module holder. To remove these radiators, you must first remove the engine radiator. The air conditioning refrigeration circuit may only be opened by a qualified specialist workshop. There is a risk of accident, refer to Section 11.
Radiator plates have sharp edges, so it is recommended to use gloves to remove the radiator.
Installation
8. Check all cooling system hoses for cuts, cracks or other damage. If necessary, replace them. Check the condition of both lower radiator rubber mounts.
9. Insert the radiator from above so that the rubber supports sit exactly in the lining (black arrows in the illustration).
10. Tilt the radiator forward and screw in the top screw on the side of the water fill pipe.
11. Install the fan shroud, refer to Section Removal and installation of the fan/fan shroud.
12. Attach the cable to the level sensor at the bottom left of the radiator.
13. Visually inspect the O-rings in the quick couplers. Replace if deformed.
14. Push in the wire retainers on the couplings. Connect the hoses to the radiator. In this case, the quick couplings should clearly snap into place, refer to Section Connecting and disconnecting the quick coupling.
15. Gasoline engine: Install the intake air filter box, refer to Section Removal and installation of the engine air filter.
16. Fill the system with liquid and remove air from it, refer to Section Coolant replacement.
