The Rein CHU0939 is an upgraded aluminum coolant hose connector designed to replace failure-prone OEM plastic connectors in BMW 6-cylinder 3.0L diesel engines. This enhanced design eliminates common failure points associated with the original plastic components, which are susceptible to cracking and brittleness caused by repeated thermal cycling and hydrolysis.

Key Features:

• High-strength aluminum construction for superior durability and extended service life
• Direct OE replacement design for easy installation
• Includes required gasket for hassle-free installation
• Engineered to withstand high temperatures and pressure
• Prevents coolant leaks and maintains reliable cooling system performance
• Replaces BMW OEM part number 11127806196

This connector addresses a common issue in BMW diesel engines where the original plastic connectors become brittle over time, leading to cracks and coolant leaks. The upgraded aluminum construction provides a more robust alternative that resists degradation from heat and chemical exposure, reducing the need for frequent replacements and lowering long-term maintenance costs.
