Hi,

I have 1993 Honda Civic LX (Sadan). The AC has started leaking all of a sudden. First I thought that I need to refill the R134. While recharging R134, I noticed that the green colored liquid is coming out of the pipe near the High end. After proper inspecting, I found that there is a leak in the join, where the pipe is joined to the base socket (Image attached).
Is there any way to stop this leak ?

yup...replace the o-ring found at the joint. You would need to evacuate the system properly, disconnect the joint replace the o-rings and recharge.

 

agreed and just something to add anytime you open an ac system you need to replace the dryer to

 

why would you need to replace the receiver dryer? If the system is properly evacuated/recovered than there is no need. Since you bring the temp up when you recover you boil out all the moister in the system.

Also I don't know if it has an accumulator or receiver dryer as I can't remember if it has TXV valve or Orifice tube.

if I remember correctly its a TXV and would have a dryer.

 

yup this is true unless its been left open for a couple days then its worth replacing.

 

Thanks a lot,

I evacuated the system and replaced the O-ring and AC is working fine.
Thanks a lot for the help,

opening a ac system makes the dryer susceptable to mositure, ruining the dryer, look it up any automotive text book will tell you to replace the dryer anytime you open the system, just a step to insure that you will not ruin the compressor of any other parts of the ac system, if you are just evacuating and recovering (not removing a line or a part from the system) no there is no need to.....

 

text book doesn't always equate to real life situations though. I have been working on A/C systems for quite some time and as long as I apply a vaccum to the system thus lowering the boiling point of the R134 than it will boil out the moisture from the system. I will agree it makes the dryer susceptable, but for the part he was replacing I wouldn't worry about it 9 times out 10.

 

civic2scooby knows his shit.. ase certified i bet..

 

agreed, but if the decicate bag fills up with outside mositure, you have no way to catch any more of it that may get into your system, we have to replace it anytime we crack the system at my shop, i would rather be safe than sorry, a $20 dryer is alot better than a $600+ ac compressor, but i do understand your point
