Original BMW Coolant Line, Electric Coolant Pump to Heat Exchanger, BMW 750i, 750i xDrive, M550i xDrive N63R (2016–2019)

On the N63R V8 in the G11 750i and the G30 M550i xDrive, this Original BMW coolant line carries coolant between the electric coolant pump and the heat exchanger. BMW's name for it is line, coolant pump to heat exchanger, and its notes tie it to the electric coolant pump. It is sold individually, weighs 247 g (0.5 lb), and is made in Germany. BMW shows this number in production from July 2015. Coolant lines like this move coolant between the parts of the cooling circuit. A line that is cracked, swollen, leaking, or deteriorating should be replaced before it fails completely.

Original BMW Parts carry a 24-month parts warranty.

This is not a main radiator hose. It belongs to the branch of the cooling system served by the electric coolant pump. This line is the one that runs from the electric pump to the heat exchanger. BMW uses the same number on both the G30 5 Series and the G11 and G12 7 Series with the N63R engine, so one part covers the V8 cars in both lines. When you inspect it, look for hardening, swelling, cracking, and leaking.
