Draining the coolant, flushing the system and adding coolant (models with a 2.4L engine) (VW Lt 28)

1. Follow the procedure given in chapter 2, taking into account the following features.

2. The drain plug is located at the bottom of the radiator inlet pipe (see photo).



3. After draining the fluid from the radiator, it is necessary to drain it from the cylinder block. To do this, disconnect either the hose at the rear of the cylinder head (see photo), or hoses on the thermostat housing.



4. When adding fluid to the system, first bring its level up to the MAX mark on the expansion tank, then start the engine and gradually add fluid as its level drops due to the disappearance of air locks.



5. Continue adding liquid until its level stops dropping.

6. Install the expansion tank plug back into place.

7. Start the engine, bring it to the temperature at which the thermostat opens, and check the fluid level in the reservoir again.
