5oz pag 46 and 24oz r134a. The amounts are from Sanden's instruction on this style of AC. Poured the oil all in the compressor. The kit didn't come with instructions.
It does have a tensioner. I just went with the shortest belt possible to prevent a squeal.
I could only find 8 groove. It doesn't seem to be the issue since the belt doesn't walk on that pulley and as far as I can tell it's all lined up. But that's just as far as I can tell with no special tools.
I'll get pictures in a bit.
