Fitment Details

  • Cracked or deteriorated rubber fitting ends
  • Restricted coolant flow from a damaged line
  • Service replacement after removal of the original Mustang turbo coolant line

Installation Notes

Verify the return-side routing and connection style before installation. Confirm the 14mm x 10 threaded fitting diameter at end 1 and inspect the mating hose and connection points for wear, contamination, or damage. This line is a molded assembly, so correct alignment during installation helps maintain the original routing on the Ford Mustang.
