Does anyone know what the part # is for the A/C orifice tube on these trucks? You would think the dealership should know but either this guy was playing dumb or he was plain dumb....Either way, I need the updated orifice line and he's no help. Can anyone here help me so I can just order by #? AC is in bad shape.

Thanks

 

Here is the part # of the orifice tube line I installed on my 06. It's the one with the new larger orifice(.067 I think). Part# 55056808AA. I did not replace the liquid line but here is the # for it too just in case. Part#55056809AA.

I did notice my high side pressure dropped after installing the new line. It seems to cool pretty well now too.

HTH.

Thanks man. I wonder if the '06 line is the same as the '03?

 

I do believe they are the same. I read it on here somewhere. I can't remember where I saw it though. You may want to do a search on here for the thread. I think it was called "03 not cooling on passenger side".

HTH.

That is the exact thread it is posted in. The line will work on 03 and up. The part number for the line is in that thread also.
