Intercooler Bleeding For ATS-V and CTS V-Sport

This video is to give you a good idea of the process to bleed and add coolant to the VSport LF3 and ATS-V LF4.  You do not need to purchase the bleeding kit to get this job done.  With schmidty tune on the car, the pump is commanded to run in accessory mode, so no need to jump, just hold the start button 5 seconds with your foot off the brake and the car will go to accessory mode.


You can do the job with: 

  • 50/50 dexcool
  • dowel or other long thin object to open valve -I used a 3/8 extension I had laying around
  • 3/4 inch inner diameter hose, clear, or rubber heater hose works
  • funnel to make easier to fill


Simply attach the hose to the filler neck with funnel, fill with dexcool, put car into accessory mode and open the valve with your dowel and allow it to gravity feed the system until no more bubbles come out and pump stays running constantly
