Part details
Part type: coolant expansion tank / header bottle / coolant reservoir.
Material: moulded plastic reservoir body with level markings and hose connections.
What it controls: coolant expansion, level retention, pressure stability, and overflow collection in the cooling system.
Where fitted: front engine bay position, left side in the direction of travel on the reference guide.
Why replace it: cracks, split seams, leaking joints, pressure loss, and coolant contamination can cause overheating and expensive engine damage.
Fault symptoms
- Low coolant warnings or repeated top-ups.
- Visible cracks, staining, dried coolant residue, or dampness around the tank.
- Overheating, pressure loss, or coolant smell from the engine bay.
- Bubbling, overflow, or uneven coolant level behaviour.
- Cap seal issues, if the cap is part of your setup.
If your original tank shows different hose positions, sensor fittings, or mounting points, stop and verify before ordering.
Fitting guide
- Allow the engine to go fully cold before opening the cooling system.
- Drain or clamp coolant as required for your setup.
- Transfer any sensors, hoses, brackets, or caps only if they match the part being replaced and are serviceable.
- Fit the tank securely and check all hose clips for tightness.
- Refill with the correct coolant, bleed the system, and inspect for leaks.
- Recheck the level after a road test and again when the engine is cold.
This is a guide only. Vehicle condition, corroded clips, and inaccessible fasteners can increase the time required.
Required tools
- Socket set and small ratchet
- Screwdrivers / hose clip pliers
- Drain tray and funnel
- Coolant test / refill equipment
- Rags, gloves, and safety glasses

Why buy the right part first time
- Less downtime.
- Lower return risk.
- Better cooling reliability.
- Cleaner fitment and less garage time.
- Used original parts can save as much as 70% versus new alternatives, depending on availability and condition.
Original equipment parts are usually a better match than low-cost copy parts because the shape, fit, and hose locations are more likely to line up correctly.
