Vacuum tank Citroën Peugeot 1622T0

Description

Vacuum reservoir for PEUGEOT 2.0i 16V 130 KW cars

Part description

The Citroën Peugeot 1622T0 vacuum tank is part of the engine vacuum system in the vacuum category. It serves as a vacuum “reserve” for the stable function of the vacuum-controlled elements even in situations where the vacuum from the motor/vacuum fluctuates for a short time. If you are dealing with erratic vacuum circuit operation, replacing the reservoir is one of the logical diagnostic steps – especially if the old piece is mechanically damaged or leaking.

Installation recommendations

Generally/typically applies to the vacuum reservoirs in the vacuum circuit (exact design and location may vary according to the specific car version):

1) Before assembly

• Compare the new and original part: reservoir shape, fitting, number and diameter of outlets and orientation of the nozzles.
• Check the condition of the nozzles and the reservoir body (cracks, deformations, broken outlets).
• Check the condition of the vacuum hoses in the area – hardened/brittle hoses often leak even after the reservoir has been replaced.

2) Necessary tools and materials

• Basic set of hand tools (screwdrivers, ratchet/extensions depending on the type of attachment).
• Pliers for clips/hose clamps (according to type).
• Cleaning agent for degreasing and clean rags.
• Possibly new clips (if the original ones are tired) – according to the actual condition of the car.

3) Step-by-step assembly procedure

1. Turn off the ignition and let the engine cool down.
2. Provide access to the vacuum circuit (removing covers as needed).
3. Before disconnecting, mark the tubes (e.g. with tape) to prevent them from getting mixed up.
4. Release the clips and carefully pull the vacuum hoses off the reservoir nozzles.
5. Dismantle the magazine from the holder/fixture (the method of fixing differs depending on the model).
6. Check the hoses and hose ends – if they are cracked or hardened, consider replacing them.
7. Clean the mating/surrounding surfaces and check that the hoses are free of debris.
8. Place the magazine in the holder and fix it in its original position.
9. Connect the tubing to the correct ports and check that they are fully seated.
10. Secure the hoses with clips so that there is no leakage and the hose does not come loose.
11. Put back the dismantled covers and check the hose routing (they must not be chafed, broken or stretched).
• 4) Post-assembly checks and test drive/function verification
  • After starting, check that there are no leaks (hissing) in the vacuum circuit and that the hoses are tight.
  • Verify the stable function of the vacuum control elements (depending on the car’s equipment) and that the problem that caused the part to be changed does not return.
  • After a short test drive, visually check the hoses and fittings again.

  5) The most common assembly mistakes + how to avoid them

  • Swapping the tubes → before dismantling, mark them and take pictures of the original condition.
  • Not tightened/poorly seated clips → after assembly, check the hoses are tightened and seated.
  • Damage to the sockets when removing the hoses → remove the hoses carefully, possibly with a slight twist.
  • Leaving hardened hoses → even a new reservoir will not help if the circuit is not leaking elsewhere.

  Reasons why the part is damaged

  • Aging of the material and microcracks leading to leakage.
  • Temperature stress in the engine compartment (plastic embrittlement, deformation).
  • Vibration and loose fitting – gradual cracking at the place of the holder or outlets.
  • Incompetent handling during service (snapped sockets when removing hoses).
  • Leaks in the vacuum circuit (tubes/clips) – the system is then more stressed and this is also reflected in the reservoir.
