Table of contents: Replacing the filter element 🠇 Condensate drain 🠇
The replaceable filter element of the fuel filter is replaced in accordance with the mileage, which is noted in the service book. In addition to the appropriate replacement of the replaceable filter element, it is necessary to regularly drain the condensate from the fuel filter housing. This is usually done when changing the engine oil.
Replacing the filter element
1. Disconnect the negative (-) battery terminal.
2. Remove the air filter.
3. Place a container under the fuel filter to collect the fuel.
4. Remove the vent plug next to the fuel filter cover.
5. Unscrew the drain plug on the filter housing and drain the condensate into a container (see illustration).
5.5 Unscrew the drain plug 1 on the filter housing and drain the condensate into a container provided. The filter cover is secured with four bolts 3
To drain the condensate, you can connect hose 2. If the car does not have a condensate level indicator light in the fuel filter, then the condensate is drained every 10,000 km.
6. Loosen the fuel filter cover mounting bolts and remove the cover.
7. Remove filter element 3 from the filter housing together with the sealing ring (see illustration).

8. Remove all O-rings as they need to be replaced with new ones (see illustration).
5.8 Remove the replaceable filter element 1 and sealing ring 2
9. Clean the fuel filter housing and install a new replaceable filter element.
10. Close the filter housing with the lid and tighten the lid mounting bolts.
11. Screw the drain plug into the bottom of the fuel filter housing.
12. Replace the air filter and connect the negative (-) battery terminal to the battery.
13. Remove air from the fuel system.
Caution! Air must be removed from the fuel system in cases where the system has been opened.
To remove air, unscrew the drain plug. Attach a hose to the drain pipe and lower the free end into a container that is placed under the fuel filter.
14. Bleed the system by pressing the manual fuel priming lever approximately 20 times until clean fuel, without air bubbles, comes out of the hose (see illustrations 5.14 and 5.14a).

15. Screw in the vent plug and remove the hose from the pipe.
16. Start the engine and let it idle until the engine operation stabilizes.
17. Turn off the engine and then start it again. Leave the engine idling and do not press the accelerator pedal to ensure that all air has been removed from the fuel system.
Condensate drain
Important! It is recommended to make it a rule to drain accumulated condensate from the fuel filter every time you change the oil. After draining the condensate, the fuel system should be bled to remove any trapped air. Some models have a condensate level sensor in the fuel filter, which is connected to a warning light on the instrument panel. If the volume of accumulated condensate reaches a certain level, the light comes on.
18. Remove the air filter.
19. Unscrew the ventilation hole plug.
20. Place a container under the fuel filter to collect condensate.
21. Unscrew the drain plug and drain the condensate into a container. Drain the condensate until clean fuel comes out of the fuel filter.
22. Screw in the drain plug.
23. Bleed the fuel system.
