Earlier this week, I wanted to check my AC. Went to install the high side R143A adapter I bought (it had the low side on it already) and figured out too late that this truck has the 3/16 high side port. I had bought the 1/4 R134A quick connect adapter. Before I realized that it was too big to thread on, I bent the Schrader valve and it started leaking. I had to order the right fitting as no store around here had one available. Ended up getting the Four Seasons 59978 as recommended by L31MaxExpress in another thread. It came in today.
Drove the Buick up to Rural King and got some more R134A ($7.49/12 oz. can). When I got back the connector was here, so I took to recharging the AC. The previous gas had all leaked out.
Installed the fitting:

Vacuumed it down (got down to 30 after an hour and a half):

After 3 of the 12 oz. cans, here is where I stopped. This was at idle:

Temperature out of the vents was 42F with it on the regular AC setting, low fan speed. On MAX with fan on high it got down to 38F pretty quickly at idle. Holding the throttle at 1500 RPM it got down to 33F. This is without the truck moving.
By the time I got done and cleaned everything up, it was time to get cleaned up myself and go do something with my lady. We took the RAM as it needed gas. So hopefully some time tomorrow I can take this truck out cruising around and see how it cools. Right now I'm pretty happy with the results and feel much more comfortable with working on the AC.
