Product Description

This Cooltec hose with bottle to top radiator hose is designed for the cooling system, serving as a crucial link between the expansion bottle and the upper radiator hose. Its purpose is to ensure the effective transfer of coolant, supporting optimal engine temperature regulation. The hose features a curved, moulded design with secure connectors to promote a reliable and leak-free fit.

This part is suitable for selected BMW 1, 2, 3, and 4 Series models (F20–F36) with 120i to 440i engines using the B48 or B58 engine codes, manufactured from 2014 to 2019. As vehicle specifications may vary, it is essential to confirm your BMW’s model, year, engine size, and engine code before ordering to ensure compatibility.

Common symptoms of a failing hose in this position include visible coolant leaks, low coolant levels, overheating, a swollen or soft hose, coolant smell under the bonnet, or warning lights on the dashboard. You may also notice poor heater performance or visible cracks and degradation of the hose material.

Replace this hose if you observe any signs of leakage, swelling, or deterioration. It is also advisable to inspect and replace hoses as preventative maintenance during major cooling system services or when replacing other cooling components.
