Omega General Help / Yet another A/C question...
« on: 21 May 2014, 12:08:54 »
Ok I'm going to attack my A/C this weekend - hopefully. So I need to order up some parts. I had the radiator pressure checked whilst changing the engine, and it checked out Ok. However, when I went to the A/C place for a re-fill it failed the vacuum test. So.. I'm going to order up...
13277003 HP Valve (which superceeds 52458177 ?)
52455752 Compressor pipework seals
3041827 Schrader valves.
I've got loads of HBNR O rings, various oils, UV dye, pressure pipes and gauges, and a cylinder of R134A from when I retro-fitted did the LC with R134a.
However, I'm wondering about the dryer. Best practice is to replace when the system is depressurised for any length of time, and the A/C has not worked in all the time I've owned the car - 4 years. EPC seems to show the complete unit (52482791) or just the dessicant insert (52464426). I'll get the prices this lunchtime, but has anyone ever changed the dessicant? Easy/Hard/Impossible?
