1999 626 AC leak
 

i have a 626 that is leaking a/c gas somehow. Ihave had the system depressurized(or repressurized) twice and i replaced the o rings on the twol ines right behind the ac condenser. the leak took about 3-4 days to expell all the gas but iam wondering how i could find the leak inexpensively. do i put on larger o rings, buy some 134 and pump it in to find the leak or do i just replace the pliable rubber lines and go from there? I cant give technical terms but i can fix things, i just need some one to give me a hint.

The best way to find a bigger leak is to put in some refrigerant which has a dye in it. Here is a link to an example of the product >>>DYE

It is more difficult to locate leaks in R134a systems as that the oil in the system is water soluable unlike the older R 12 days.

ok. i know when we repressurized the system there are 2 spots to connect the cables. one is in the rear of the engine compartment(rightside) and the other is right by the strut mount(also right side). my question is, at which point do i put the stop leak in?i know there are the 2 different points on the a/c lines so i guess as long as i dump it in the right spot, this should help.which spot is the right spot? isthis something i can do or is this to be done by a professional?

You install the dye the same fashion as refilling the refrigerant through the low side fitting. It is a blue color cap. Just install when the refrigerant is low again. Use the same hoses to install and run the a/c a few days to circulate. If you can install the freon, you can do this.

sweet. It got super cold here so the ac can wait. Question...does anyone know whereto get a hold of some sunvisors? floormats? for a 99 626lx(color code g3)?

There are only three places that come to mind...dealer, salvage yard, or ebay.
