Ok, so I just flat screwed up on this one. I was replacing my radiator on my '99 LX470. When I was pulling it out I obviously got it caught or banged it on something, because All of a sudden a big old hiss from the front area. It was pretty loud, so I felt it best to vacate the area until it stopped. Pretty clearly it was an AC line or something, cuz nothing else has that sort of pressure. I went ahead and got the radiator done so I could go buy some AC dye and find the leak, however now I can't find it even with the dye. I can hear it hissing immediately when I put more in, but the dye is not showing up anywhere. It's either right at the front at the condenser or one of those lines right around the radiator. Do you have any idea where it could be coming where the dye wouldn't be seen? Of course I'm heading on a road trip at the end of the week so if I can't figure this out by the end of the day, it's going to the shop and big bucks coming my way I'll bet. Anyway any advice would be super appreciated!
