Car Forum / Dodge / Dodge Trucks / September 2008AC Leak
I've emptied the first 120z can of R134a into my truck's AC via the low-pressure point and it's still not even up to 25psi. Is it possible the low-pressure valve is actually the leak? I noted at one point when I took the hose off, dye bubbled up around the valve pin. And, it seems the more R134a I put in, the messier it is getting around that valve. I'm making very sure the thing's on as far as it will go, and I'm not seeing dye peppering out when I've got the trigger down. I'm also noticing a bit of inconsistency in the valve reading. Sometimes it looks like I'm making progress. When I switched bottles, the gauge told me all those gains were lost. Advice? jmc > I'm also noticing a bit of inconsistency in the valve reading.

I think you've exhausted the options you have... time to seek out a shop and get it repaired. Sorry - I was hoping it would be easier for you.

Personally, I'd consider going to a person with some serious A/C experience at this stage. You may be missing something obvious, or you could be doning something wrong. > >I've emptied the first 120z can of R134a into my truck's AC via the > >low-pressure point and it's still not even up to 25psi.

And be sure to tell them you put sealer into the system, lest you be on the hook for damages to their AC equipment.

I don't *think* I'm doing anything wrong, but then we never do, do we, until proven otherwise? jmc > Suddenly, without warning, PeterD exclaimed (9/22/2008 9:43 AM): >> [quoted text clipped - 23 lines] > I don't *think* I'm doing anything wrong, but then we never do, do we, > until proven otherwise? You could also try the R-134a with the added dye,. Just don't get the stuff with the "leak seal" as it gets into everything and could end up plugging more than just a hole up. > jmc |
