This used OEM BMW heater coolant hose, OEM part number 6993464, was removed from a donor vehicle. Also known as a heater coolant line, this hose routes engine coolant to the cabin heater core. It is designed for BMW X3 and X4 models equipped with the 2.0L turbocharged four-cylinder or 3.0L turbocharged six-cylinder gasoline engines, including the mild-hybrid (MHEV) variants. A cracked or leaking heater coolant hose can cause loss of coolant, overheating, and a lack of cabin heat.
