A used OEM BMW heater coolant hose/line (part number 6993452) is now available. This genuine rubber or silicone hose carries engine coolant to the heater core in the cabin; when it cracks or leaks, you may notice coolant puddles under the vehicle, low coolant warnings, or insufficient cabin heat. Fits BMW X3 and X4 models equipped with the 2.0L turbocharged four-cylinder or the 2.0L mild-hybrid turbo engine. A common failure point that should be replaced promptly to avoid overheating.
