PAG 150 vs PAG 46

custom 68 on Sat May 15, 2010 10:26 AM User is offline

hello all and thanks for the forum. I am working on a 1968 chevy pickup that has been retrofitted with a 2002 5.3 liter motor. I am using the same 2002 compressor. I have an "updated" POA as it is called from Old Air. last year when I got this going I found info that lead me to use PAG 150, now with this great site it appears like I need PAG 46. I assume this is thinner and I should flush this out and go with the PAG 46.
The system is currently open as I was doing some work over the winter and it was in the way. I will be evacuating and filling the system as soon as I can getting ready for the power tour.
thanks a ton
Dave

The 2002 used PAG 46.

thanks for the info but I keep getting confused the more I look and learn. I removed the compressor and found a note that says "use only 12345923 synthetic oil" I may be wrong on the date the engine is a retrofit and I believe it to be a 2002 however it might be a year older? I am going to keep digging and get all the numbers off the compressor.. so confusing
so all the references I see point me back to the PAG 150. Did they make a change or is the cross references for this oil number wrong.
Again thanks
Dave

Which compressor do you have, HU6 or 10S20F? HU6 uses PAG 150.

I know this should not be this hard but i looked and teh only number I found besides the oil number is "1136623"
so I guess I dont know other than the oil number.
thanks

Judgment call then as both compressor look similar.

thanks, I will look at the thing a little closer
I am also looking for info on how to drain the oil out so I can start fresh with the correct amount.
