The coolant expansion tank is essential for your vehicle, acting as a reservoir for extra fluid during temperature shifts. However, frequent exposure to extreme conditions makes it susceptible to cracks or breaks. Maintaining all coolant within the system is vital for optimal engine function. If you detect any damage, such as cracks, broken nipples, or compromised mounting points, swift replacement of the tank is necessary to uphold your vehicle's cooling system integrity.

While the modern B48 and B58 powerplants are incredibly robust, BMW’s choice of brittle plastics for their cooling loops remains a major weak link. This upper radiator vent hose runs constantly hot as it returns pressurized coolant back to the expansion tank. After years of being baked by engine bay heat, the thin plastic neck and internal quick-disconnect seals degrade. A hardened factory plastic line can snap at any moment, spraying coolant everywhere.

The coolant expansion tank provides a place for excess coolant to flow as temperatures rise and fall. Because it’s exposed to constant heat cycles and pressure changes, it can eventually crack, split, or suffer damage to its nipples or mounting points. Keeping coolant properly contained within the system is essential, so if your tank shows signs of wear or damage, replacement is necessary. This direct-fit replacement installs easily and delivers the same heating and cooling performance as the factory unit. When replacing the tank, be sure to have additional coolant on hand. ECS Tuning carries a full range of vehicle-specific coolants designed to meet OEM specifications. Most German vehicles require specialized formulas—using the correct coolant will help prevent corrosion and ensure long-term reliability.

This performance heat exchanger from CTS features a number of upgrades over the stock intercooler, offering better reliability and cooling performance. The first major upgrade is the heat exchanger's full alumnimum constructions. The factory heat exchange is partially constructed from plastic, which is prone to damage and cracks as the plastic becomes brittle over time. Full aluminum construction results in a stronger intercooler, which will last the lifetime of your BMW. The second major upgrade is a redesign of the coolant flow path and fin layout. This redesign allows for higher cooling efficiency, resulting in greater heat dissipation and reduced coolant temperatures.

This is the fan that turns on when the air conditioning is activated electronically. It’s not driven by the belt and it pushes air through the condenser. If it breaks, it might be an electrical issue that usually occurs in the motor within the fan, as it will fail to engage. There is also a chance that the blades might get damaged as well. No matter how your fan got damaged, be sure to replace it to keep air circulating evenly.

BMW's S55 motor is a modern marvel but one weak point, which Active identified is the entire cooling system for the intake which comprises the charge pipe, the aftercooler and the heat exchanger (or radiator). Finally there is a S55 aftercooler kit upgrade that is good enough to carry the Active Autowerke brand. Years of success in developing cars for motorsport has allowed Active to leverage its expertise to the top-mount charge air cooler on the F80 M3, F82 M4 and F87 M2 Competition. This aftercooler was made for the S55 and crafted using only high-grade aluminum to outperform the factory aftercooler in all situations from everyday driving to the toughest racing. The factory cooler was built to support a specific power target and environment. Many of you have increased the performance of the S55 which quickly overwhelms the stock cooler leading to heat soak and higher intake air temperatures which triggers the ECU to downgrade the performance until cooler air returns. Active's focus was not on a mass-market aesthetic add-on but a properly engineered improvement over the existing hardware. Active uses a tube-and-fin core designed specifically for the S55 and included turbulators to maximize the cooling efficiency in as small a package as possible. The end tanks are billet machined aluminum, not cast, folded, or bonded and ensure even distribution of the water throughout the internal aftercooler cores. High precision fittings, CNC machining, and TIG welding throughout ensures the highest quality construction to prevent pressure loss, and the lowest weight, in a bolt-on replacement. But Active also didn’t leave the aesthetics by the wayside as we dip the visible top of the aftercooler in a carbon fiber coating giving your installed cooling system a decidedly top market look to match the improved cooling performance. The Active silicone charge pipes for the F80 M3, F82/F83 M4 and the F87 M2 Competition improve the flow over the stock, compressed plastic pipes. The Active Silicone Charge Pipes allow you to maximize power on your F8X by securing all the boost that your S55 is making. These pipes replace the hot-side pipes leaving the turbos and into the top-mount aftercooler. The stock S55 charge pipes are notorious for developing hairline fractures at their plastic seams. These fractures or cracks are unnoticeable to the naked eye, but under boost pressure they open up leaking the desired charged air into the engine bay, and consequently can rob your S55 of it's full power potential. In addition, these leaks can trigger your S55's turbochargers to work harder to hit and maintain target boost pressure, potentially wearing them out sooner. Active uses silicone in this area because it will not contribute to heat soak and it's easier to mold for the correct clearances. Active uses a 5-layer silicone hose with all needed adapters and stainless hose clamps included. It fits perfectly with our CNC’d top-mount cooler.
