The Z51 cooling package comes with a 3rd radiator in the right side rear opening behind the passenger door . I didn't order the Z51 package and am now tracking the car and would like the extra cooling . I put in the brake ducts and upgraded the brakes . Looking to see if anyone has done this yet ?

I've added the radiator to the driver side along with the required additional coolant hoses. It would be the same for the passenger side radiator. The fan and shroud/trim is the same. The radiator will drop in place of the existing plastic that the fan bolts to. You need someone that knows how to find what you need in the GM parts online catalog.

Puzzled, the Z51 does not have an extra rad on the driver's rear fender scoop side, only the passenger side and that routes to the DCT liquid/liquid heat exchanger. If you added one to the driver's side where do the entry and exit coolant lines go?

It plumbs inline between the water pump and the oil cooler.
All the parts needed are (were when I ordered) available directly from GM if you know where to look in the online catalog.
The radiator itself is exactly the same part number as the passenger side Z51 rad.
I have since repurposed the driver side rad to cooling my heat exchanger fluid on my turbo setup 🙃
To add the passenger side rad, all you would need is the radiator and a few different sets of hoses/quick disconnect fittings. All of which is available through GM.
