Product Description

The Cooltec Hose Engine to Thermostat is an essential component in your BMW's cooling system, designed to securely channel coolant from the engine to the thermostat. This cooling radiator hose is engineered to handle the high temperatures and pressures found in the engine bay, ensuring effective coolant flow and helping to regulate engine temperature. Its contoured shape and flanged mounting end are intended to provide a precise fit for select BMW models, supporting reliable sealing and straightforward installation.

This hose is compatible with various BMW models, including those in the E87, E88, E82, E90, E84, E85, and E86 ranges equipped with N52, N52N, or N53 engines. Always check your vehicle's model, year, engine size, and engine code before purchasing to ensure correct fitment.

Typical symptoms of a failing engine-to-thermostat hose include visible coolant leaks, low coolant levels, overheating, bulging or cracked hose surfaces, and the presence of coolant odours under the bonnet. You may also notice the engine temperature fluctuating or warning lights appearing on the dashboard.

It is important to replace this hose if you notice any signs of wear, cracking, or leaks, or during major cooling system maintenance. Over time, rubber hoses can degrade due to heat and pressure cycles, so proactive replacement can help prevent unexpected breakdowns.
