Has anyone replaced all the components of their a/c system and how hard it is? I have a substantial leak in my '98 EB system. I've tried stop leak with dye to find leak, but no luck. Freon is out in one week. Any advice would be appreciated.

Did you use the black light to search for the leak? If not it is very hard to see the dye. One spot people overlook are the service ports.

Black light with the yellow glasses. Don't forget to forget to check the end of the evaporator drain line. If you can't find the leak it is probably the evaporator that is leaking.

I don't use the yellow glasses, don't see a difference with or with out them. Front seal on the compressor is a known leak point on an aged unit also.

If you don't see the dye then it is time to get the sniffer out.

The beeper/sniffer that Ac shops have is the way, as Stamp stated. You might be able to borrow one. I wouldn't change all the parts without knowing what's broke, that's just lazy mechanics. Not to mention what if you do all that and find out it was something else! Take the time have someone find the problem, have them evacuate system then you fix. After that you throw back in pag oil, and appropriate amt freon.

Once they come to after seeing the cost of the rear line set they will take a different line of action.

Last time I looked one up it was just under $500 for two pipes. And that was about 2 years ago. Probably no longer in stock.

Thanks for all your inputs! I will take to a local mechainic with a leak detector to isolate the issue and go from there. I've had my '98 Expy for 18 years and has been solid and definitely don't want to get rid of it!

I replaced everything "under" the hood on my 2003 about 4 years ago. Did not change out evaps or line to rear unit, but I did flush. I don't remember exact cost, but somewhere around 1000. Compressor was about 40-45% of cost. Used named brands die parts. Not to difficult, biggest challenge was getting the compressor bolted on. Mine is 2wd, 4.6.

How do you "flush" your a/c unit? Mine probably need it bad, considering all the stop leak i've used over the years. I thought evacuation would be appropriate...

Cjennjr if you take your ac to anyone that is going to evacuate the system, Please tell them you have used stopleak. If you don't it plugs up their very expensive machine which they should then charge you to fix.
