Replacement Procedure

1. Completely drain the coolant.

2. Remove any parts which impede access.

(Example : transmission, injection pump)

3. Place the screwdriver to the deepdrawn edge of the core

plug and pull forward and then rotate 90°.

4. Pull out the core plug with pliers.

5. Thoroughly clean the sealing surface and apply Loctite 241.

6. Install the new core plug by using a drift.

Drift 102 589 00 15 00 (F34)
Drift 102 589 12 15 00 (F17)

7. Install the removed parts and fill the coolant.

Notice

The adhesive must be allowed to harden for about 45
minutes before filling of coolant.

8. Warm up the engine and check the coolant for leaks.
