Top Off A/C 134a
I got pissed at my A/C today and got a can of 134a to see if I can top off the system. Now I can't find the low pressure inlet. Anybody ever seen it?
I'll look until I find it but it sure is not easy to find.

Okay, just in case anybody out there ever gets inclined to do this, I found the low pressure inlet. Had to take off the air filter top cover, up behind it underneath the cowl by where the big wire harness connectors are.
I attached the refrigerant hose, quick connect kind, and followed the instructions on the can. The system sucked all the refrigerant in about 2 minutes out of the 14oz. can. I used "Arctic Freeze Ultra Synthetic 134a+". I don't know anything about this stuff, I just reached my level of frustration with my A/C where I just wanted to do something, never paid attention to brands or options here.
It worked like a champ though. I took a quick ride up and down the street and my A/C works MUCH better. Nice to have immediate results.

Not true, if you over charge you can lock up the compressor, called slugging and it can cost you the compressor, dryer and orifice tube. You should never charge an A/C system without using manifold gauges. I know that some will argue. Let's go back to Clint. Do U feel lucky today?? They don't make gauges for the hell of it.

I think my system was low because the radiators have been disconnected 3 times for service/replacement. Cools better now and I think I will spend the extra coin for the refill bottles that come with the gauges in some kits. I think it was around $35 at Wal Mart.
