So, does that mean that compressor and other component changes at >4080 prompted the update, or that it applies to all, including previous VINs. BTW, mine is 1890.
So, I called DMCH, and they say that the Red Tek charge should be 11 oz, regardless of the previous R12 charge spec. And, the only reliable way to get the right charge is to vacuum it back down and start over.
