I just purchased this ATS. I want to replace the coolant. Would you please explain to me the proper steps in draining and replacing the coolant on this vehicle. I have previously obtained information from regarding changing the coolant on my Cruze, as it was the first closed/pressurized system I did and appreciated the information to prevent air bubbles from forming in the coolant system. Thank you in advance for your expert advice.

Hello,

I have provided the information that you requested, the guide from the vehicle manufacturer for the draining and filling of your vehicle's cooling system in the diagrams down below. I also included the coolant capacities and fastener torque values for the cooling system as well. I hope that this helps.

Thanks,
Alex
