Product Description

This Cooltec hose connects the expansion tank to the cylinder head in the cooling system of select BMW models. Its role is to direct coolant flow efficiently, helping to maintain optimal engine temperatures and prevent overheating. The hose features durable plastic construction with secure molded connectors, including a locking tab for reliable attachment.

Designed specifically for BMW 1, 2, 3, and 4 Series models (F20-F36) equipped with B46 or B48 engines from 2014 to 2020, this hose ensures proper fit and function. Always confirm your vehicle's model, year, engine size, and engine code before ordering to guarantee compatibility.

Signs that this hose may need replacement include coolant leaks near the connectors, visible cracks or splits, engine overheating, or loss of coolant pressure. If you notice any of these issues, inspect the hose for damage or deterioration.

Replacing this hose is essential when it shows signs of wear, brittleness, or leakage. Delaying replacement can lead to coolant loss and potential engine damage, so address symptoms promptly to maintain system integrity.
