Installation recommendations
Generally/typically replacing the air pump is a straight piece-for-piece swap, but the exact steps may vary by specific car model and make.
1) Before assembly
- Compare the part numbers (9653340580, 1618E4) and shape/fit to the original pump.
- Check the condition of the connector (pins, connector fuse) and the surrounding wiring.
- Inspect the air hoses/lines connected to the pump – cracks, loose clips, hardened rubber parts.
- Verify that water/dirt has not entered the pump (typically by traces of moisture and deposits in the surroundings).
2) Necessary tools and materials
- Basic set of gola/ratchet and extension, possibly screwdrivers depending on the type of connections
- Pliers for clips (depending on design), small flat pry bar for loosening hoses
- Cleaning agent for degreasing, rags
- Protective gloves and goggles
3) Step-by-step assembly procedure
- Turn off the ignition and disconnect the battery (recommended because of the electrical component).
- Ensure access to the pump (depending on the car, it may be necessary to divert covers/lines in the vicinity).
- Take a photo of the original hose and connector routing for correct orientation during reassembly.
- Disconnect the electrical connector of the pump – do not pull on the cables, release the connector lock.
- Release the clips and disconnect the attached air hoses/lines.
- Loosen the fasteners and remove the original pump from the bracket/storage.
- Clean the seating surfaces and surroundings, check the holder and any silent blocks/supports (if included).
- Place the new (used) pump in the housing and screw/fasten it.
- Reconnect the hoses in the same configuration and check that they are properly seated and secured with clips.
- Connect the electrical connector and make sure the fuse clicks.
- Reassemble all the removed covers and elements in the vicinity.
- Connect the battery and do the first boot.
-
4) Post-assembly checks and test drive/function verification
- Check for air leaks (loose hoses/clips) and wiring for tension or contact with hot or moving parts.
- Check that the pump does not behave abnormally during operation (unusual noise/vibration).
- If you have diagnostics, check for any saved bugs and check if they come back after fixing them.
5) The most common assembly mistakes + how to avoid them
- Swapping or incorrect fitting of hoses → mark or take a picture of everything before disassembly.
- Not tightened/incorrectly fitted clips → check all connections after assembly.
- Connector damage when disconnecting → always release the fuse and do not pull on the cables.
- Ignoring the condition of the line (cracked hoses) → the fault can appear as a faulty pump; also check the surrounding elements of the system.
Reasons why the part is damaged
- Intrusion of moisture into the pump or connector (corrosion, stuttering).
- Clogging with dirt and subsequent increased load on the pump motor.
- Damaged or leaking hoses – the pump is operating outside normal conditions and may wear out more quickly.
- Electrical problem (bad contact in the connector, oxidation, transition resistance) leading to overheating.
- Vibrations and loose fitting – increase the mechanical stress on the pump body and connectors in the long term.
