Coolant pump, 4-cyl.

Coolant pump, 4-cyl.

Warning

Take care if the car is warm. The coolant is hot and there is also a risk of burning yourself on the exhaust manifold.


To remove


1. Open the cap on the expansion tank and release the pressure.


2. Raise the car.

3. Remove the lower front cover.

4. Drain off the coolant.

5. Lower the car to the floor.


6. Unplug the mass air flow sensor connector.

7. Remove the air hose and mass air flow sensor.

8. Release the tension of the poly-V-belt using 83 95 254 Drawbar handle, hydraulic belt tensioner .


9. Remove the belt from the power steering pump and water pump.

10. Disconnect the crankcase ventilation pipe from the turbo intake pipe using the quick coupling.


11. Unplug the boost pressure control valve connector.

12. Remove and move aside the engine's lifting lug ans wastegate valve.

13. Remove the bypass pipe with valve.

Note

There is an O-ring on the bypass pipe attachment to the turbo intake pipe.


14. Remove the exhaust manifold heat shield. The heat shield is attached with a nut and two clips underneath.


15. Remove the turbo intake pipe.

16. 260 hp: Remove the upper screw from the wastegate unit and slacken the lower screw.

17. Remove the intake pipe.

18. Remove the hose from the wastegate valve.

19. Plug the turbo inlet using a plastic plug or the like.

20. Undo the power steering pump.


21. Move the power steering pump aside.

22. Remove the hose clips and hoses on the coolant pump inlet.

23. Detach the two longitudinal coolant pipes from the engine block.

24. Detach the two longitudinal coolant pipes from the coolant pump.

25. Slacken the bolt (by the turbo) securing the coolant pipe from the coolant pump.

26. Remove the coolant pipe from the coolant pump.

27. Undo the coolant pump retaining bolts.


28. Carefully work the pump free from the bracket and from the pump's connecting piece on the engine block.

29. Remove the connecting piece from the engine block and inspect its seals, Change the seals as necessary.

Important

It is normal for a very small amount of coolant to pass via the coolant pump shaft seal in order to lubricate it.



To fit


Note

Spray the connectors with 30 04 520 Anti-corrosion agent .



1. Connect the connecting piece to the cylinder block. Grease the seals with White high-pressure grease paste .

2. Fit the coolant pump.
