I believe it’s apart of the secondary cooling system found on the max trailer tow package.
Im ER no MaxTow. Nothing on the driver side of the 12v@Grumpy2 SR Pro/Max Tow/Missing Pass
@Dudel5000 ER Pro/Max Tow/Missing Pass
@mrau ER Lariat/No Max/Missing Driver
@Lpotter86 ER ??/No Max/ - Are you missing the passenger side?
Additional data from cars I have access to:
Myself, ER Lariat/Max Tow/Missing Pass
SR Pro/No Max/Missing Driver
SR Pro/Max Tow/Missing Pass
Data seems to point to the cooling loop. I wonder what happens if we add another chiller? 20,000lbs towing capacity?!
