Basically, the clutch is defeated so its always on.Air gap must be checked even if you bought a new compressor with complete factory installed clutch because they are often set up wrong. I always check air gap and also bench test the clutch on the compressor to verify its moving in/out properly.

I did not measure the gap. But it's there, small, and it works on and off, so figure it's fine. This compressor runs all the time if a/c is on. Only shuts off when a/c is turned off.
