Maintain optimal engine temperature and pressure with a precision-engineered coolant reservoir. OE-fit quality, durable construction, and integrated sensor ports ensure reliable cooling system performance.
The expansion tank houses excess engine coolant as it heats and expands, maintaining system pressure and preventing overheating. A properly functioning tank and cap together ensure safe pressure relief and coolant return during shutdown.
Inspect expansion tank and cap every 24 months or 40,000 km. Replace at first signs of cracks, discoloration, or cap failure to maintain system integrity and avoid overheating.

You can enter your Vehicle Registration Number on our homepage or manually select your vehicle details. We will then filter the parts that match your vehicle. Always double-check the Product Properties section to confirm correct fitment.
Yes! We’re constantly expanding our product range and catalog. If you can’t find the part you’re looking for, please contact us. We work with several manufacturers and may be able to source the part for you.
Many product pages include a Fitment Details tab with additional information. If you still have questions, feel free to use our message service — we’re happy to help.
Parts do not come with additional items like fitting kits or gaskets unless it is clearly specified in the Part Details section of the product page.
Brake Discs: Most standard brake discs are priced individually, but for safety reasons, they must be purchased in pairs. When required, we will automatically set the quantity to 2 in your basket.
Brake Pads: These are sold as a set (either front or rear), so one box is enough for two discs.
The Compatibility Table can be found on each product page, usually below the main product description. Look for a tab or heading labeled Compatibility.
