VAICO V20-1711 Radiator Coolant Hose Compatible with BMW - X5 E53

The VAICO V20-1711 is a precision-engineered expansion tank coolant hose designed as a direct replacement for BMW OEM part number 17127509966. This hose connects to the bottom of the expansion tank and plays a critical role in your vehicle's cooling system by routing coolant between the expansion tank and other cooling system components.

Key Features:

• Direct OEM replacement quality from VAICO, a trusted European aftermarket manufacturer
• Replaces BMW part number 17127509966
• Engineered to meet or exceed original equipment specifications
• Made from durable materials designed to withstand high temperatures and coolant exposure
• Precision-molded for proper fitment and routing

Over time, coolant hoses become brittle and are susceptible to cracking and splitting, making replacement essential to prevent leaks and potentially catastrophic cooling system failure. This VAICO replacement hose restores proper coolant flow and system integrity, helping maintain optimal engine operating temperatures and preventing overheating issues.

Installation Notes: When replacing expansion tank hoses, it is recommended to inspect all coolant hoses, clamps, and the expansion tank itself for signs of wear or damage. Consider replacing the expansion tank if it shows signs of cracking or is over six years old, as preventative maintenance can help avoid unexpected cooling system failures.
