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.
