Product Description

This Cooltec Expansion Tank with Cap is a brand new cooling water bottle designed specifically for Mercedes-Benz models. The expansion tank is an essential component of your vehicle's cooling system, helping to regulate coolant levels and maintain optimal engine temperature during operation. Its robust plastic construction and integrated cap ensure a secure, leak-resistant seal for reliable performance.

This part is suitable for select Mercedes-Benz vehicles, including Vito and Viano models with various engine sizes produced between 2004 and 2016. Always confirm your vehicle's model, year, engine size, and engine code to ensure compatibility before purchasing.

Typical symptoms of a failing expansion tank include coolant leaks, low coolant warnings, overheating, visible cracks or swelling in the tank, and steam from under the bonnet. You may also notice engine temperature fluctuations or a persistent coolant smell around the engine bay. Addressing these issues promptly can prevent more serious engine damage.

If you observe any of these symptoms or notice physical damage to your expansion tank, replacement is recommended. Regular inspection and timely replacement help prevent coolant loss and overheating, ensuring your engine stays protected and runs smoothly.
