Product Details

The Rein 17-12-7-519-247 is an OE-quality expansion tank coolant hose designed as a direct replacement for BMW cooling systems. This upper fitting hose connects the expansion tank to the upper radiator area, playing a critical role in maintaining proper coolant circulation and system pressure.

Key Features:

  • Constructed from premium rubber compound resistant to heat, salt, oil, and road debris for extended service life
  • Features integrated thermoplastic quick-connect fittings for easy, leak-free installation
  • Includes pre-installed O-rings to reduce installation time and prevent comebacks
  • Approximately 39 inches in length with precision-molded bends for exact OE fit
  • Manufactured to ISO quality standards by Rein Automotive

This hose is engineered to match the exact size, shape, and fitting configuration of the original equipment part. Rein cooling system hoses are designed to resist electrochemical cracking and withstand temperatures up to 135°C, ensuring reliable performance in demanding conditions. Replaces BMW OE part number 17127519247 and supersedes 17127521775.

Excellent prices, incredible shipping

Easy transaction

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

Good service so far

Best price and super easy to use.

Wow the quick service and low prices at autoplicity helped me and made it easy to find which car parts retailer is the best!
