• Description:

  GM part 12670757 is a Turbocharger Coolant Return Pipe Assembly.

  What it is

  • GM Part Number: 12670757
  • Description: Turbocharger coolant return pipe / coolant line
  • Function: Routes coolant back from the turbocharger to the cooling system after it absorbs heat from the turbo

  Where it’s used This part is found on several GM small turbocharged engines, commonly:

  • 1.4L turbo (Chevrolet Cruze, Buick Encore, Chevrolet Trax)
  • 1.5L turbo (Chevrolet Equinox, GMC Terrain in some applications)

  Fitment varies by engine code and model year, but it’s generally part of GM’s turbo coolant plumbing on compact and midsize turbo engines.

  What it does (simple explanation) The turbo gets extremely hot during operation. This pipe is part of the cooling loop that:

  • Carries coolant away from the turbo
  • Helps prevent overheating and oil coking inside the turbo
  • Maintains turbo reliability and longevity

  Common failure symptoms

  • Coolant leaks near turbo area
  • Low coolant level warnings
  • Sweet smell of coolant after driving
  • Visible crusty residue around metal coolant lines

  Related info

  • It is typically a direct-fit molded steel/rubber coolant line
  • Often replaced if corroded, leaking, or damaged during turbo service

  If you want, I can map this exact part to your vehicle—just send your year/make/model or VIN, since GM uses this same number across multiple engine platforms but with slightly different routing depending on configuration.
