I see where you are coming from.....but this is a GM made unit, not a aftermarket one. It was installed by the dealership and looks to be a solid unit worth the effort!

I agree, after reading alot more....I am going to replace all old O-rings before I button it up. I have located a couple of cans of r12 for purchase, I will take it to a local shop and have them vacum/purge the sytem, check for leaks.....then I will have them Pro's install the r12. Thanks for the feedback Guys!!!
