Part Identification & Technical Details
Correct Vehicle Body-Style Reference
The photographs below are provided to help identify the Mazda 3 BK 5-door hatchback body generation. They are reference vehicles only and are not the donor vehicle for this component. Colour, trim, wheels and engine appearance can differ. Final fitment must still be confirmed using the chassis, diesel engine specification and physical component.

- Mazda 3 1.6 petrol Z601 / Z627 — this is a diesel-component listing.
- Mazda 3 1.6 diesel 90HP / alternative engine specification — not confirmed from the supplied item evidence.
- Mazda 3 2.0 diesel — not confirmed.
- Mazda 3 4-door saloon — not confirmed from this photographed application.
- Mazda 3 BL generation — do not assume fitment just because the registration year is 2009 or later.
- Ford, Volvo, Peugeot or Citroën models — the visible Ford mould mark does not establish vehicle compatibility.
- Any vehicle where the hose connections, mounting tab or reservoir shape differ from the photographs.
Buy The Correct Part First Time
Before clicking Buy It Now, please check ALL of the following:
- ✓ Your vehicle is a Mazda 3 BK, not the later BL generation.
- ✓ Your vehicle has the 1.6 MZ-CD / DI Turbo diesel engine.
- ✓ Your existing reservoir has the same overall moulded shape.
- ✓ Both vacuum-hose connection positions match.
- ✓ The mounting tab / fixing arrangement matches.
- ✓ Any readable number on your original component is compatible with the replacement.
- ✓ For a 2009 vehicle, confirm the BK chassis rather than relying on registration year alone.
What This Part Does
The vacuum reservoir — also described as a vacuum chamber or vacuum tank — forms part of the diesel engine's vacuum-control system. It does not electrically control the vehicle itself. Its role is to provide a stored/buffered vacuum supply so connected vacuum hoses, solenoids and vacuum-operated control components can receive a more stable vacuum source.
Service access: Mazda service information for the MZ-CD 1.6 Y6 reaches the vacuum chamber after battery/battery-tray removal, moving the fuel-filter assembly aside and removing the under-cover. This is more useful than guessing a left/right location from a generic engine-bay photograph.
Possible Symptoms Of A Damaged Vacuum Reservoir
A cracked, leaking or physically damaged vacuum chamber may contribute to symptoms such as:
- Hissing or other evidence of a vacuum leak.
- Visible cracking around the reservoir body or hose nipples.
- Vacuum hose connections which no longer seal correctly.
- Inconsistent operation of vacuum-operated engine controls.
- Vacuum-related engine-control faults or reduced performance where the control system cannot maintain the required vacuum.
- Intermittent symptoms which change with engine load as available vacuum changes.
Why Choose An Original-Manufacturer Part?
Cheap copy components may look similar in an online photograph while differing in moulding detail, hose-port dimensions, mounting position or material construction. A correctly matched original-manufacturer component provides the same type of physical design originally intended for the vehicle application.
Fitting Guide
- Switch the engine off, allow it to cool and secure the vehicle safely.
- Record or photograph the existing vacuum-hose routing before disconnecting anything.
- Remove the battery cover and disconnect the battery negative terminal as required for safe access.
- Remove the battery, battery box/clamp and battery tray where required for access.
- Remove the fuel-filter protector and carefully move the filter assembly aside without damaging pipework.
- Remove the relevant under-cover / undertray access section.
- Identify the existing vacuum chamber and compare it directly with the replacement before removal.
- Carefully release the vacuum hoses. Older hoses and plastic connections can become brittle, so avoid levering aggressively against the nipples.
- Remove the chamber retaining fixing / mounting point using the correct tool for the fastener fitted to your vehicle.
- Fit the replacement chamber without twisting or loading the moulded hose connections.
- Reconnect each vacuum hose in its original position and ensure each connection is fully seated.
- Inspect the surrounding vacuum hoses for splits, deterioration and loose connections while access is available.
- Reassemble all removed components in the correct order.
- Start the engine and check for hissing, loose hoses, vacuum leakage or abnormal operation.
Typical Tools Required
Estimated Repair Time & Garage Labour Guide
Planning estimate: approximately 0.5–1.0 labour hour for an experienced technician where access is straightforward. Corroded fixings, damaged hoses, additional diagnosis or difficult access can increase the time. This is not a manufacturer flat-rate time.
Because active JavaScript calculators are not suitable for an eBay description, use the static guide below. The calculation is simply: garage hourly rate × labour time = estimated labour cost.
| Garage Rate | 0.5 Hour | 0.75 Hour | 1.0 Hour |
|---|---|---|---|
| £50 / hour | £25.00 | £37.50 | £50.00 |
| £60 / hour | £30.00 | £45.00 | £60.00 |
| £70 / hour | £35.00 | £52.50 | £70.00 |
| £80 / hour | £40.00 | £60.00 | £80.00 |
| £90 / hour | £45.00 | £67.50 | £90.00 |
| £100 / hour | £50.00 | £75.00 | £100.00 |
| £120 / hour | £60.00 | £90.00 | £120.00 |
| £150 / hour | £75.00 | £112.50 | £150.00 |
