AC Service Port Schrader Valves
 

Hello. I've got a leak from the service ports on my wife's 2014 RDX (3.5 AWD w/ Technology package). I had requested the schrader valves be replaced in both high and low sides, and the system recharged. The next day I received a call back to inform me that the valves are not replaceable on this model, and that the entire line would need to be replaced. We don't have a super local Acura dealer, and I don't trust the local Honda dealer. I've never heard of a vehicle where the valves were not fairly easily replaceable (although I am sure there is one or two examples out there.

Is anyone able to confirm if this is true? Do I really need to replace the lines just to fix a leaking service port?
