  • Durable construction to withstand everyday wear and tear

A lot of heat is created when an engine is running, but only about a third of this heat energy is used to power the vehicle. Roughly another third goes out the tailpipe and the remainder is absorbed by the engine’s metal components. If this heat isn’t dissipated, an engine will soon fail. The cooling system removes this heat and maintains a regular operating temperature that is ideal for performance and longevity. Coolant circulates through passages in the engine, where it absorbs the heat from the metal. The coolant is then pumped to the radiator where the heat is transferred to the surrounding air.

To ensure peak engine performance and long engine lifespan, perform regular cooling system maintenance and when you need replacement parts, choose Rein. With Rein you can be assured of perfect fit and optimal function because all Rein parts are made to OE specifications in quality certified manufacturing facilities.

Got the Job Done
It was a direct OEM fit. This one was a lot cheaper than the OEM one from Mini for the same exact thing. As far as I can tell beside the little Mini is stamping on it.

Exact Fit The First Time!
Finding Audi parts is difficult at best, and I was surprised to find the parts I needed right away. It was easy to order and arrived quickly. The part was an exact fit and worked perfectly. I will be coming back the next time I need parts! Best of all, the part was surprisingly affordable.
