I have a 18 Colorado v6 and mine are a 22mm socket. I’m not sure if there’s a difference between 4 and 6 cylinder, but i did buy the wrong size socket after reading many forums that they use 19mm.

This is wrong. The correct size is 22mm. I bought the wrong size socket because of this wrong answer.

On a 2018 ZR2 the size socket is 22mm. Maybe on the other models a 19mm will work.
