Product Description

Keep your BMW’s cooling system functioning properly with this Moca expansion tank with cap, designed for effective coolant storage and pressure regulation. This cooling water bottle is essential for managing coolant overflow and maintaining the correct pressure in your vehicle’s cooling system. It is specifically designed for selected BMW petrol models, offering compatibility with F20, F21, F30, and F31 series.

Fitment is strictly for BMW models as indicated, so always confirm your vehicle’s model, year, engine size, and engine code before placing your order. Using the correct expansion tank ensures a proper fit and reliable performance, preventing issues that can arise from using incompatible parts.

Common symptoms of a faulty or failing expansion tank include visible coolant leaks, low coolant warning lights, overheating, coolant odours in the engine bay, or cracks in the plastic tank. You might also notice steam from under the bonnet or fluctuating temperature gauges. Any of these signs indicate it is time to inspect and possibly replace your expansion tank.

Replacing the expansion tank is recommended if you notice any leaks, cracks, or signs of pressure loss, or if your vehicle is experiencing overheating issues. Regular inspection is advised, especially in older vehicles or those with high mileage, as plastic tanks can become brittle over time.
