On a 2000 F-150 4.6 I am in the process of replacing the A/C compressor, drier and oriface tube. I am stuck trying to remove the drier hose leading into the evaporator. I have a plastic release tool that I have used in the past to remove the heater hoses but I have fought this coonection for over two hours and I need advice.
Thanks in advance!

It was a pain but... Got it! Now my next question is, I pulled my oriface tube and it is loaded with crap. Is there a filter I can put on my compressor line to keep debris from going in it?

 

you need to flush the system thoroughly. It is required to have a good flush for the compressor warranty to be valid. Read the details of the compressor warranty. The crap probably came from the dryer.

 

I have not flushed it. The way I understand it the path the freon takes is from the compressor > condenser > oriface tube > dryer. I am replacing all of those parts and pulling a vacuum on the system. Hopefully that will take care of it.
Thanks for your input!

 

And it goes through the evaporater after the orifice tube. Did you replace the evaporater or flush it?

 

No sir I didn't. I kind of thought that the oriface tube caught the debris. It was not totally clogged. I sure hope I don't have a problem....

I probley should have. I can't complain much. This old truck has 545,000 miles on it and the air conditioner parts are all original.

 

Yeah, you may be right about the orifice tube collecting the debris. Wow, that's a lot of miles. On the original engine with no rebuilds?

 

Tore it down and rebuilt it at 306,000 miles.

 

I received my new Motorcraft condenser today. It has a notice in it that the freon charge qty will be lower. The OE system called for 33oz. The new condenser calls for 1.85 lbs. or 29.6 oz.
Have any of you guys heard of this? Does the condenser determine the amount of freon in all systems?
Thanks!

 

I would guess that the internal volume of the condenser is 3.4 oz less than the oe condenser. The refrigerant should be liquid while it is in the condenser so volume difference there will make more difference in system volume than the evaporator where the refrigerant is gas.

 

Up and running great!
Thanks for your help!
