Frequently asked
How do I know a part will fit my car?
Enter your registration above and we cross-check against the TecDoc catalogue to narrow the list to expansion tanks listed against your vehicle. Specifications can still vary between trim levels and engine variants, so we recommend confirming the part dimensions against your existing component before fitting.
What brands do you stock?
We stock established manufacturer brands sourced through trade channels. The brand row at the bottom of this page shows which manufacturers we carry for expansion tanks. We don't sell unbranded parts.
How quickly will my order arrive?
Most orders dispatch from our Northampton warehouse within 1–2 working days. Free standard delivery on orders over £40 to most UK mainland locations.
What if the part doesn't fit?
Please check our returns policy for the current terms. If you're unsure about fitment for your specific vehicle variant, please contact our team before ordering using the details at the bottom of the site.
Can I check fitment before ordering?
Yes — every product page shows whether the part is listed against your selected vehicle. Where multiple sizes exist for the same vehicle, the dimensions are shown so you can compare against your existing part. If you're unsure, contact our team for help confirming the right option.

About Expansion Tanks
Our expansion tanks range is built from established UK suppliers and trusted aftermarket brands. Each product is mapped against OE/OEM references and TecDoc ktype data so the reg-lookup above filters to only the parts that fit your specific make, model, engine and trim.
Enter your registration to see exact-fit options — or browse by brand using the tiles above. The full catalogue covers most major makes and models on UK roads, with same-business-day dispatch on stock items ordered before 2pm.
Engine and cooling system parts
Engine and cooling parts span a wide spectrum — timing belts and chains, water pumps, alternators, starters, gaskets and seals. Some are service-interval items (timing belt every 5-10 years or 60-100k miles depending on engine), others are catch-it-early items where small failures can lead to bigger ones if ignored.
Common engine warning signs
- Whining or rattling from the front of the engine — failing belt tensioner or alternator bearing.
- Coolant loss with no visible leak — head gasket, hose or water pump seal.
- Charging warning light or dim headlights at idle — alternator output dropping.
- Slow cranking on cold mornings — starter motor or battery, both worth checking.
Don't postpone a timing-belt service
The biggest avoidable engine failure on the UK fleet is timing-belt overrun. If your service book is missing or the previous owner's record is unclear, get it checked — replacing a belt costs a few hundred pounds; replacing the engine after a belt snap on an interference engine runs into thousands.
