Product Description

Keep your BMW's engine cooling system working efficiently with this Moca Expansion Tank with Cap, designed for the cooling water bottle system. This expansion tank stores excess coolant and helps maintain the correct pressure in your vehicle's cooling circuit. It features clear MIN, MAX, and COLD level indicators for easy monitoring and a secure threaded cap with a pressure element to ensure proper sealing.

This part is compatible with select BMW petrol models, including certain 1 Series (E81, E82, E87, E88), 3 Series (E90), X1 (E84), and Z4 (E89). Always confirm your BMW's model, year, engine size, and engine code before ordering to ensure the correct fitment.

Common symptoms of a failing expansion tank include coolant leaks, visible cracks, low coolant warnings, engine overheating, or fluctuating coolant levels. You may also notice steam from under the bonnet or a sweet smell from leaking coolant.

Replace the expansion tank if you observe any leaks, cracks, or pressure loss, or if the cap is no longer sealing properly. Timely replacement helps prevent engine overheating and protects other cooling system components from damage.

MiMi Auto Parts offers reliable cooling solutions and delivers nationwide across South Africa. For peace of mind and the right fit, always double-check your vehicle details before purchasing.
