Dealer install - secondary radiator (M7)?
I'm wondering if a GM dealer can order and install the GM secondary water radiator on 2015 C7 Z06 3LZ M7 (without Z07 option), and about how much it would cost? I don't track the car so I probably don't need it, but if it isn't too expensive, I might consider it anyway.

I'm pretty sure a dealer would. If you get a dealer to do it also order the radiator from him. That way if there's an issue it's all on him. You can get them online for under 1,000 but unless you're going to install it yourself I wouldn't recommend that.

When the GMPP unit first came out in 2016 I checked with my local dealer's parts department and they price matched the lowest price (including shipping) I could get from the online sellers. I installed the unit myself as it is very easy to do. To do you need to get the car off the ground enough so you can work under it, remove the left front wheel, remove the under tray and the center panel above it, remove the left front wheel housing, apply a template to the bottom of the radiator inlet duct and use a box cutter to cut a hole in the duct floor. Then install the radiator in the opening. After that drain coolant out of the cooling system, disconnect a couple of hoses and connect a couple of others followed by putting things back together. The hardest part is figuring out how to get the 4 bolts that hold the radiator to the bottom of the duct threaded into the two brackets that rest on the top of the piece of plastic. I did that by inserting a long screw driver through the grille to push the brackets into place behind the grille and then hold them (each had 2 captured nuts) in place while turning the bolts from under the car.
The problem with having the dealer install the part is that is not part of their normal operations and they usually charge an arm and a leg more than their standard rates to do the work.
Including sales tax I paid $925 for the radiator 3 years ago.
