Aluminum Coolant Tank - Audi B5 A4 | B5 S4 | C5 Allroad

Our Aluminum Coolant Tank comes with a pressure relief valve in the cap, a sight glass, a coolant level sensor and AN fittings (-6 return and -10 supply). We pressure test each tank to 30 psi for 1 hour.

The aluminum construction is ideal for for single turbo applications where the down pipe runs a little too close for comfort to the factory plastic bottle. This coolant tank was designed to have a similar shape as the factory bottle so it will be a direct swap on any set up.

The AN fittings can be changed to barb fittings in the add-on section. The tank comes bare aluminum, polish it, leave it as is, paint it, or chose to have us powder coat it for you – available in black sandtex only in the add-ons. Other powder coat options available as custom request, please contact us before purchase as longer lead time and an additional fee may be applicable.

We guarantee quality products – every time!
