Detailed Description
Rein CHT0738 turbocharger coolant line is manufactured to the same fit, form, and function as the original part. The hose material selection is intended to handle the thermal and chemical exposure common in turbocharged cooling systems, where heat, oil, and ozone can accelerate rubber deterioration. This makes it a solid replacement when the original BMW coolant hose shows signs of age, leakage, or cracking.
