Hey everybody. I've got a 2011 Crown Vic and I'm trying to replace a leaky schrader valve on my AC lines, but apparently I've got some kind of larger version of the valve that I'm not familiar with. I went to the local AC shop and the guy looked at mine and let me have one he'd removed from another car. I have this kind of valve on both the high and low pressure lines where you hook your vac gauges to. Does anyone know what this kind of valve this ones called or where I can get replacements, or what the tool is that would take it out? My regular schrader valve tool is too small for it.
