Genuine BMW M4 Coolant Reservoir Cap

The BMW M4 Coolant Reservoir Cap forms a seal that seals the pressurized fluid inside the recovery tank. It is a reliable barrier against air and leaks. This Coolant Reservoir Cap features a precision spring valve that allows expanding coolant to flow into the reservoir and pulls it back as temperatures fall. As a result, temperature swings never create vacuum pockets that could stress the powerful M4 engine on the road or track. Drivers of early metal tank and later model year plastic tank setups on first and second generation BMW M4 vehicles can thread this Coolant Reservoir Cap straight to the factory tank without any need for an adapter. It is fitment guaranteed to work on the recent BMW M4 competition coupe as well. Each Coolant Reservoir Cap contains a tough rubber seal that prevents dirt and metal shavings from entering high-performance coolant, which protects the aluminum block while preventing antifreeze from spilling onto the pavement. The Coolant Reservoir Cap is constructed with the right type of ruggedness that allows it to endure the repeated heat cycles that take place during spirited outings in a BMW. Furthermore, the later and lighter version saves grams to add to the pared down curb weight that makes the M4 so agile. The Coolant Reservoir Cap, when fitted into place, maintains system pressure to allow the intercooler and radiator to operate at peak effectiveness and supports the car's legendary four-second sprint. Every BMW owner knows that this high revving coupe needs proper cooling, and the Coolant Reservoir Cap provides that. Upon detecting a bulge or leak, a fresh Coolant Reservoir Cap can be fitted to instill confidence before any high rev blast. It is for these very effective little components that have earned a reputation for reliability similar to that of the wider BMW performance ethos witnessed by every M4 owner and the characteristic BMW driving thrill.
