Finally got around to doing this on my C7 ZR1 yesterday.

Yup, from the factory these C7 Z and ZR's aren't properly done before they are sent to dealers FS. Glad I did mine took a whole bunch of air out of both systems now it's filled properly and no more worries about limp mode and heat soak.

Great information and great job! What equipment did you end up using/buying?

I bought the Cooler Bleeder, it's an actual item sold in the US and does a much better job at removing air from Corvette CAC systems (can also be used on Caddys and Camaro) than the special dealer tool and manual pump and hose setups, and from Amazon I bought a 6cfm dual stage vacuum pump.

It migrates to my basement and hibernates till I'm ready to bring the car out then flies back onto the car. (less chance of damaging it when car is stored and I have to move around it in the garage). :p

This aftn I decided to do both intercooler systems again on my ZR1. It was pretty well bled the first time I did it but because of the "issue" I had when I first hooked up everything (discussed in the video) I wanted to make sure things were set up and worked properly right from the get go.

So all the stuff went into the garage and I got to work, this time grounding the electronics properly got everything working perfectly the instant I turned on the bleeder and vacuum pump. The majority of the air was removed previously but this time I let each side run for 15-20 mins and it got a tiny bit more air out of each side. Basically whereas I had huge air pockets coming out of both systems the first time I did this, this time the air being removed from the system was more like dime/nickel size pockets and still weren't that many of these coin size air pockets coming out of my dual CAC systems. 2 pics I took after each side was done shown below, the first time I opened the plug on the driver side system you could not see coolant at all, after I did this side the first time the coolant was at the bottom of the opening and this time redoing it it's right up to the top. I did a better job on the pass. side previously so this time the level after I was done was only slightly higher than the first time doing it.

Still glad I redid both sides again, now I'm confident 99.9% of the air is removed (if not ALL the air).

I have an ad in classifieds offering to bleed CAC systems on C7 Z06/ZR1, C6 ZR1 + certain Camaro SC models for a small cost if you are in the GTA area. If you drive these cars and have never had this done YOU WILL HAVE AIR IN THE SYSTEM. PM me to get this taken care of so your car will run to its potential.
