The trick is -
Add a little to low side.
Wait 5 mins.
Temp goes down a bit.
Add a little more.
Temp may go down. Or may go up.
If it goes up - stop - over charged.
If you keep putting in more and then the compressor starts to cycle - then way over charged.

GOOD RESULTS SO FAR....I went the simple route first (cheapest) and cleaned the condensor a few times with some simple green and low pressure rinse- the dirt and bugs coming out were minimal, but there nonetheless! Then I hooked up the low side and pressure tested it according to the instructions and it read lower than it should've- Went out and grabbed the "high mileage" coolant from IDQ w/ stop leak, conditioners, driers, etc-- (first can i added a few days ago didnt have "stop leak".....ended up having to add about 3/4 of the can (took your advice jfail--worked perfectly) and is now on 2 full days of COLD AIR! Fingers crossed and thanks again to everyone-

I understand you are a mechanic and all, but anybody who had ever read the 2 pages on our D2 t/stat and heater core knows, with the heater hoses by-pass, especially in the summer, your coolant system will loose a 15% plus amount of cooling efficiency. So that being said, read it if you don't believe me then don't doe this mod.
