the compressor has an oil drain bolt - its the large hex right next to the connector, rebuilt/aftermarket compressors are shipped with very light oil in them, you need to fill and drain the compressor to wash out the shipping oil then refill with correct oil charge before installing. If you bought a denso new compressor they come shipped with about 100 ml PAG46 oil in them.

reason to post is that - you may have flooded the compressor with oil if you didnt remove the sump bolt (and if your supplier put some oil in there), this creates a problem with these units - the volume metering device on the suction plate of the compressor will stall and you wont get any pumping even with full 1000 grams charge.

I hope you bought the updated type compressor, its got a smaller volume metering valve and is named as Denso 7SBU16C. The original ones 7SB16C have a design fault where one suction reed fractures from its base plate and siezes the unit
