Keystone BM3110101 Radiator Fan Shroud OEM Replacement - 17111723031

The Keystone BM3110101 is an OEM-replacement radiator fan shroud designed to restore proper cooling system function. This single-fan design shroud mounts directly to the radiator and channels airflow efficiently through the radiator core to maintain optimal engine operating temperature. It also serves as the mounting point for the coolant reservoir.

Key Features:

• Direct OEM Replacement — engineered to match the fit and function of the original factory part
• Single fan design — radiator-mounted configuration matching the original equipment layout
• Coolant reservoir mounting point — integrates the overflow/expansion tank bracket as on the OE unit
• 6-cylinder application — specifically designed for inline-6 engine variants
• OEM Reference: Replaces BMW OE part number 17111723031
• Partslink Number: BM3110101

A damaged or cracked fan shroud significantly reduces cooling efficiency by allowing recirculated hot air to bypass the radiator. Replacing a broken shroud restores the engineered airflow path and helps protect the engine from overheating. This Keystone unit is a cost-effective alternative to the dealer-sourced part with OEM-matching fitment.
