Bottles & Reservoirs

Cooling bottles and reservoirs

These parts hold coolant and manage expansion in the cooling system. Listings cover overflow bottles, coolant reservoirs and expansion tanks, which are not always the same style.

The main differences are whether the bottle is a non-pressurised overflow bottle or a pressurised expansion tank, plus the fittings on the unit. Some come with a level sensor, some need the sensor transferred, and cap supply can also vary.

Check before you order

• Overflow bottle or pressurised expansion tank
• Level sensor fitted or not
• Cap included or transferred
• Hose positions against the old bottle
• Engine and build range

For handed parts, the listing states the side. The build month range is also shown on each listing. If you are not sure which one suits your vehicle, send your VIN through the contact page.
