Yesterday I started my truck and smelled a weird chemical smell, after driving a few yards I noticed what appeared to be smoke coming from my hood. I pulled over and it looks like the oring on my ac high side hose going into the condenser blew out. When I turned the truck off I could hear a loud hissing noise and could feel air rushing out from where the line couples into the condensor. This is a new truck to me. Ive only had it a month so Im not sure the history but it looks like it has a new compressor and the refrigerant appears to have had dye in it. I first thought my radiator had a hole in it due to green liquid dripping out. My question is this. Is this a common thing that happens? Can I just replace the o ring? Do I need a whole new hose? Auto zone has a pack of o rings but I wasnt sure if those would work or if I need to get a special size. Any special instructions I need to know about replacing the o ring? Looks like pep boys has a vacuum pump for the ac for around $80. I figured I would pick one up and have it on hand if I ever need it again. Thanks for your help.

It would help if we had a model year.. As far as dye, Nissan started putting green dye in their A/C systems at the factory somewhere around the 2000 model year or so. If the hose is not damaged or leaking, there is no reason to replace it; you can just replace the "O" ring. It's not what I would consider a common thing, but, perhaps, when they replaced the compressor, they did not tighten the bolt on the hose enough? Most auto parts stores carry "O" rings; just have to match it up and lube with A/C oil before you install. Whether you get a vacuum pump and do it yourself or let a shop do it, is up to you, but, if it were me, I would want to see what high and low side pressures are after recharging to make sure they are in proper range.
