Product Information

This coolant hose flange connects the upper radiator hose to the engine block. A known failure point on many BMW engines, the original composite flange is prone to cracking either during hose removal or over time due to thermal cycling. Major coolant leaks on the left side of the engine are often traced back to this part.

This upgraded aluminum flange from Rein offers superior durability and long-term reliability over the original design. It includes the required seal for proper installation between the engine block and flange.

Includes: Engine coolant hose flange and engine block seal

Function: The flange serves as a connection point for the coolant hoses and helps maintain proper flow and pressure in the cooling system. A secure seal at this point is critical to prevent coolant loss and maintain optimal engine temperature.

Common Failure Symptoms:

  • Coolant leaks: Cracks or damage to the flange can cause visible leaks under the vehicle or on engine components.
  • Overheating engine: A broken or leaking flange disrupts coolant circulation, leading to engine overheating and potential warning lights.
