Product Details

The Rein 17-12-7-521-775 is a premium replacement coolant water hose designed to connect the expansion tank to the radiator in BMW vehicles. Manufactured by Rein Automotive, a trusted supplier of OEM-quality cooling system components, this hose ensures reliable coolant flow and maintains proper engine operating temperatures.

Key Features:

  • Direct OEM replacement for BMW part number 17127521775
  • Engineered to exact OEM specifications for precise fit and function
  • High-quality construction designed to withstand heat and pressure cycling
  • Connects expansion tank to radiator for efficient coolant circulation
  • Manufactured by Rein Automotive, a leading aftermarket parts supplier

This water hose is a critical component of your vehicle's cooling system, responsible for routing coolant between the expansion tank and radiator. Over time, cooling system hoses can deteriorate due to constant exposure to heat, pressure, and coolant chemicals. Replacing worn or damaged hoses helps prevent coolant leaks and potential engine overheating. The Rein 17-12-7-521-775 provides reliable OEM-quality performance at an affordable aftermarket price.
