Replacing the pulse air filter (Mondeo 1)

The pulse air filter is mounted in petrol engines on the front side of the engine next to the exhaust manifold. It belongs to the pulse system, in which fresh air is dosed into the exhaust gas during the rotation phase of the heated engine, resulting in its better afterburning. The filter should be cleaned regularly only in case of heavy dustiness of the highway. No special tool is required.

The following spare part is required: Filter oil (Ford aerosol oil).

1 - Pulse air filter/valve body 2 - Pipe for fresh air intake into the exhaust manifold 3 - Pulse air filter/valve body (bottom view) 4 - Air regulation valve 5 - Vacuum hose to control valve 6 - Engine speed/position sensor 7 - Fresh air intake 8 - Lambda probe 9 - Soundproofing 10 - Foam filter 11 - Aluminum cover 12 - Pulse air filter housing (other elements as per top fig.)

Unscrew the valve body parts from each other from the top.

Remove the lower part of the case downwards.

Remove the foam filter inside and inspect it. If it is heavily soiled, wash the filter with gasoline and then dry it.

Caution: Remove contaminated materials without causing harm to the environment.

Spray the filter with air filter oil.

Insert the filter with air filter oil.

Insert the foam filter into the bottom of the housing.
