Product Description

This Cooltec hose connects the waterpump to the thermostat, playing a critical role in the cooling system of select BMW models. Designed to handle coolant flow, it features a flexible, ribbed construction to accommodate engine movement and temperature changes. Proper coolant circulation is essential to prevent overheating and ensure optimal engine performance.

This hose is suitable for various BMW models, including those with N52, N52N, and N53 engines. It is important to match your vehicle's model, year, engine size, and engine code to confirm compatibility before purchasing.

Common symptoms of a failing waterpump-to-thermostat hose include visible cracks, leaks, swelling, or soft spots on the hose. You may also notice coolant loss, engine overheating, or a low coolant warning on your dashboard. Addressing these issues promptly helps avoid more serious damage.

Replacement should be considered if the hose shows signs of wear, leakage, or if the cooling system is being serviced. Always inspect hoses during routine maintenance, as age and heat can cause deterioration even if no symptoms are present yet.
