This coolant expansion reservoir tank is a direct OEM replacement assembly equipped with sealing cap and integrated fluid level sensor, engineered exclusively for BMW 5 Series F10 and F11 chassis 528i models. As the vital cooling system component, it stores excess radiator coolant, balances cooling system pressure, and monitors coolant liquid levels in real time to protect the engine from overheating damage during daily driving and highway travel.

Basic Product Details

Constructed with high-temperature resistant reinforced polypropylene plastic body, paired with durable EPDM rubber sealing ring, leak-proof threaded cap and factory-calibrated coolant level sensor. The complete kit also includes the matched mounting bracket for fast installation. Installed on the engine bay cooling system compartment, every port, thread and sensor connector precisely duplicates original factory dimensions. This reservoir fits all BMW F10/F11 528i production years equipped with the standard gasoline cooling system.

Core Product Advantages

We upgraded the vulnerable design flaws of original BMW factory expansion tanks. The thickened reinforced plastic housing resists thermal expansion and contraction caused by continuous engine temperature fluctuations, effectively avoiding common cracking and coolant leakage issues of stock tanks. The upgraded silicone seal cap delivers lasting pressure sealing performance, while the pre-calibrated fluid sensor maintains accurate liquid level feedback long-term. Fully pre-assembled with cap, sensor and mounting bracket, this unit requires no extra parts matching, drastically cutting installation time for DIY vehicle owners and professional auto repair shops.

Solvable Vehicle Pain Points

Aging or defective coolant expansion tanks trigger frequent cooling system troubles for BMW F10/F11 528i owners. Typical issues include coolant reservoir cracking and slow fluid leakage, persistent low coolant dashboard warning alerts, inaccurate liquid level readings, insufficient system pressure leading to engine overheating risks, and brittle original plastic brackets breaking easily. Most car owners suffer repeated small leaks and intermittent warning lights due to weak factory plastic durability; this upgraded expansion tank permanently eliminates these widespread cooling system recurring faults.

Compatible OBD & VCDS Fault Codes

Replacing the faulty coolant expansion tank clears cooling system diagnostic trouble codes triggered by leakage and abnormal level sensor signals, including P0504 (Coolant Level Sensor Malfunction), P2556 (Coolant Level Circuit Error), and intermittent engine overheat precaution warning codes stored in the vehicle ECU.

Logistics & Shipping Benefits

We offer complimentary nationwide free shipping across the entire United States to help you cut down luxury vehicle maintenance costs. All in-stock coolant tank assemblies pass strict pressure and leak testing before packaging, secured with shockproof packaging materials. Orders are dispatched within 24 business hours from US domestic warehouses for quick delivery, so you can rapidly repair your cooling system and prevent engine overheating failures.

Warranty & DIY Installation Support

Each OUSIMY coolant expansion tank set comes with a formal quality warranty covering manufacturing defects and non-artificial premature cracking or leakage. It is a 100% bolt-on direct replacement that aligns perfectly with original mounting positions and electrical plug interfaces. No drilling, cutting or complicated coding adjustments are needed, allowing experienced car enthusiasts to finish the whole replacement procedure at home easily.
