2006 dodge ram 3500: much oil..freon..the air conditioning compressor

This answer was rated:

How much oil and freon do you need to put in when changing the air conditioning compressor on a 2006 dodge ram 3500 mega cab?

Hello and welcome to JustAnswer!


There isn't a set amount of oil that goes in with compressor replacement. When replacing a compressor you drain the oil out of the old compressor, measure it, and then add the same amount of VC-46 PAG oil to the new compressor. If you have a Mopar compressor it will already be filled with 6 ounces, which is the total system amount. You'd need to drain this and put back in the correct measured amount.


The system holds 1 pound 14 ounces of refrigerant.

Is it pretty difficult to change? The compressor that is.
No, it's not hard at all. After the refrigerant is recovered you will remove the belt, the lines from the back of the compressor, and unplug the clutch connector. Then remove the four 13mm bolts that hold the compressor to the engine and remove the compressor. It takes me about a half hour or so to replace one.
