A/C valve leaks
« on: June 18, 2017, 05:08:50 PM »
my 98 DD has been needing a shot of gas each summer. a few weeks back I hit it with a can and it cooled good. just didn't last. Found the low side Schrader valve has a tiny leak. I'd rather not bleed the system down just to change the valve. has anyone tried these things?

Started with nothing and still have most of it left.

Unless the system was totally de-pressurized at some point and outside air point into it, I'd have no issues trying those fitting. For $20 what have you got to lose.

I have the Mastercool master kit with those valve core removers. They do what they claim. No complaints. Hopefully you don't have ports instead of schrader valves. Some ports have non replaceable valves and you must replace the port. I use nylog lube/sealant when I replace the valves. Just a drop on the seal area the threads and open the valve and spread the excess on that seal.  The valves are allowed to leak up to 1/4 oz a year by design. The cap is supposed to seal that small leak off.

Finally got all my packages delivered on this. a new core and I popped for the mastercool setup. it was a bit more but seemed to be a better quality set. everything went well with one small exception.

The set looked well made. everything was brass or aluminum so it should last for a while. and it attached to the leaky lowside port without any issues.

The core remover tool did go in and thread the OEM core out, but heres where it got sideways. the core remover wouldn't pull the oem core out. it was loose in the remover barrel and I could thread it in and out but never could get it out. I finally unthreaded it and pulled the core remover out and opened the valve and blew the oem core out into a shop towel. thumbsup2 The replacement core would go into the remover and stay ttached but upon closer inspection the oem core had a bigger button on it and wouldn't fit down in the hole so whenever you tried to remove it the core would fall out.

The tool will work it just needs a slight mod to it before next time. I lost minimal gas so I'm happy. Put a can of gas in and its putting 55F out of the dash vents with a 97F ambient. thumbsup2 I'm back to riding in a cool pool.  th-bounce

Its downright uncivilized to not have A/C in south Texas.

Sorry you had a problem with the tool. The master kit has 5 different valve shafts to fit the typical valve cores. Most likely you got the wrong shaft. Great that you used your head to find a way to get the valve core changed. OK also is a place that needs air conditioners it gets almost as hot as Texas.

not sure if the shaft isn't correct or if the oem valve core stem has a burr on it. The replacement  went right into it  shrugx shrugx  I may never need it again so I'm not too concerned about it now. grinx
