Review on 💨 High Low Pressure Tool for Removing and Installing R12A Air Conditioning Valve Cores by Luis Esquivel

The top and bottom tool turned out to be very good quality and had my high side service port included a core I think it would have worked. My 2003 GMC Sierra 1500 truck didn't have a removable core on the high side. Looks like you need to replace the entire service port housing on my truck. However, I think these tools would be a life saver for most cars or a low side service port on my 2003 GMC Sierra 1500 truck.
