It doesn't look like the clutch is engaging but I'm not 100% sure (my eyes aren't what they used to be). You should hear a click/clunk from the clutch when it kicks in and the center part of the clutch will start spinning. There may be a power relay nearby - don't confuse the click from it with click from clutch.

The pulley is spinning. I don't think I hear a click of the clutch engaging...but I feel like I've never heard it for some reason. Or my exhaust is too loud.

Either should work, right? We use R134a, not R-12.

I don’t think there’s much difference besides the price.

Default 370z ac issue
My AC isn't working as well. On another topic. How do I go about creating a new thread on the forum. I trying to sell a brand new Varis front spoiler for a 370Z that hasn't been used. I'd like to post a new thread for those that may be interested. If anyone can give me insight it would be greatly appreciated.

The pulley spins whenever the engine spins. If the clutch is engaging, the center part will spin when the compressor needs to run. If the center part never spins, you have a clutch problem.

If the clutch is not working, check voltage going to the clutch. If the clutch is working, then check refrigerant charge, as per others above.
