The Gates coolant tube replaces the coolant line from the oil cooler to the heater on 2002–2011 Freightliner Columbia models with the 14.0L 6‑cylinder diesel engine. Intended to restore the factory coolant routing, this tube reinstates the proper flow between the oil cooler and heater circuit for the specified Freightliner applications and replaces the original factory tubing.
