Ok, I'm back again...longer than intended. Hopefully I can still get some advice to keep me moving along!

I guess before deciding which type of coolant to use, I'll do as VS and Larry suggested...determine my first step regarding the compressor condition.


This morning I spun "the forward most part in front of the pulley" of the compressor as suggested. I WAS able to spin this part (not the pulley) by hand. It spun easily (not freely) and smoothly.

This means the A/C compressor is NOT seized, right?

VS suggested the next steps: cleaning, replacing the receiver/dryer and vacuum, then a recharge.

What should I do for proper cleaning?

Also, I have assumed that the coolant leaked out. To check this I will take VS's suggestion and carefully press on one of the shrader valves for a second.

Honestly, I do not know where the shrader valves are, and I just searched an image to see what they look like. I'm a mechanically-inclined person, but still learning the mechanics! I'm figuring I will find this when I go back to the vehicle, but if it's tough to find, I'd love if someone can describe where to find it.

Thanks again everyone....
