all of it.

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

So I hit the wrong button and posted too soon.

The vehicle is a 2001 Chrysler T&C 3.8L with rear AC. I need oil capacity and what oil type and viscosity. I had the clutch go, I put a second clutch in and it fried as well started slipping once the high side got to 250, then got a third clutch from junkie and that went as well. Posted earlier on these issues, and consensus was that compressor was going bad. Plan is to replace compressor, accumulator and flush condenser and evaporator and lines. I will be using the Dura II flush solvent. Any suggestions on this would be appreciated.

With all of the other things you've done you should also replace both front and rear expansion valves. All-data shows a total 11.4 ounces of oil for the complete system. You always want to add the oil to each of the different components after flushing. I would do 7 in the compressor, 1 in the drier, 1 in the condenser and 1 in each of the evaps.

Take care,

backflush the condenser and make sure both the TXV's are removed to flush the front and rear evaps separately.

I plan to do that. I will blow everything out with dry air first then use the Dura II flush.

Also as it has been suggested to replace the expansion valves, I have seen a couple of posts on aftermarket expansion valves for a 2001 Chrysler don't have the correct size hole for the temperature switch. Can anyone comment on that? Do I need to source them from chrysler. Thanks!!

I see 13 oz of Pag46 instead of 11.4 oz. Might want to double check on that.

Thats why I am posting here to hopefully get correct answers to thing like this. I dont have access to anything that would list the exact amount and type of oil. The car is a 2001 Chrysler T&C 3.8L with front and rear AC. Planning on a full flush so it will be a full oil charge. Thanks for looking out i really appreciate that!

Also has anyone had issues replacing the expansion valves with aftermarket and the temp sensor doesnt fit? Do I need to buy from Chrysler?
