91 Honda Accord air conditioning leak
My 91 Accord's A/C is blowing warm air. I first figured that I needed a
freon refill, so I wanted to give that a try. When I tried to empty out the old refrigerant, I couldn't get good vacuum pressure on the line. Obviously, I suspect a leak in the line. Is there an effective way to pinpoint the location of the leak, and is there a particularly effective way to seal the leak? Or am I overlooking something else that I can't think of? |

If you can't get close to a reasonable vac then the leak is quite big (but check it's not leaking at the connector). Try pumping a little bit of air in (not too much as you don't want to introduce moisture). You should hear it leaking out somewhere. I've seen quite a lot of Hondas high pressure pipes fail under the pipe clamps (traps moisture, etc), 2nd favourite is the condensor www.poolecool.co.uk |

91 Honda Accord air conditioning leak
Soap bubble test, flourescent dye, electronic leak detector all come to
mind. The local Autozone has a rack full of AC tools and supplies, including leak detectors. If you want to try the shotgun approach, buy an O-ring kit and replace all the O-rings in your system. One doesn't normally "seal" AC leaks, but rather replaces the defective part. A vacuum pump is not a good way to evacuate a system which might have refrigerant in it. If you manage to suck liquid, you could damage your pump. Nowadays "they" recommend a recovery station. Earle > wrote in message oups.com... > My 91 Accord's A/C is blowing warm air.
