When we removed the orifice tube, stupid me didn't note the orientation. The posts that I found while searching referenced the brake booster, which in the 99 STS, it is not in line with the AC line containing the orifice tube. Can anybody remember which end faces the radiator?
Right now, I have it installed with the arrow pointing away from the radiator. Long end towards the firewall. Is that correct? Seems like it isn't cooling like it should and we flushed it thoroughly.
The compressor puts a load on the motor that seems excessive, and the cooling lines shake abit. When we originally put in the Freon, it was quiet, didn't have what I thought was an excessive load. Right now it seems to "tick" when running, and I know it isn't the belt, and it didn't do that when we put the compressor in on Friday.
I was just thinking maybe I had the orifice tube in wrong, or that maybe it got clogged up with debris that we missed, although I rather doubt that.
