Product Description

This Cooltec hose connects the radiator to the oil cooler in select BMW models, forming an essential part of your vehicle's cooling system. Designed specifically for BMW applications, it ensures efficient transfer of coolant between the radiator and oil cooler, helping to regulate oil temperature and maintain engine performance. This hose features a curved rubber construction with robust mechanical connectors, including a plastic quick-connect fitting and an integrated mounting tab for secure installation.

Compatibility is limited to BMW vehicles, particularly those in the E81, E82, E87, E88, E90, E84, and E89 series. It is crucial to double-check your BMW’s model, year, engine size, and engine code to ensure correct fitment before ordering.

Common symptoms of a failing radiator to oil cooler hose include coolant leaks near the hose ends, visible cracks or swelling on the hose, engine overheating, fluctuating oil temperatures, low coolant levels, and a strong coolant smell from the engine bay. You may also notice warning lights on the dashboard or visible drips under the vehicle.

Replacement is recommended if you observe any of these symptoms or during scheduled cooling system maintenance. Timely replacement prevents coolant and oil cross-contamination, reduces the risk of engine overheating, and helps avoid costly engine repairs.

Order your BMW radiator to oil cooler hose from MiMi Auto Parts for reliable service and nationwide delivery across South Africa. Our team is ready to assist with confirming compatibility and answering your technical questions.
