  • Hello, Question on Fleece Coolant Bypass. I have a 2006 Ram 2500, automatic, with a rusty Y tube. Can I just delete the trans cooler tubing, plug the ports, and use the new heater core tube without the rear t-stat set-up? Just a every day driver. Thank you, Jay

    Here is the installation manual.

  • Does this kit include the heater core tube as shown in video?

    JStorer | 1/13/2022

    No. Fleece does not include that tube any longer.
