Just to help, here is a picture of the rear liquid line where the factory in-line filter (Marked by red square) goes.

 

Thank you very much. I would rather replace it now and get it over with.


I found it on ebay for around $6. Is there a special tool to get that fitting loose there, or do you just remove the clip and pull it apart?

 

You use a standard A/C Quick Disconnect Tool. You may also need to remove the line from the "Y" block to get the line to drop down. That's what I had to do. I would also use new O-Rings. The end that has the filter in it takes 3 O-Rings (7.37mm x 1.81mm). The "Y" block end takes 1 O-Ring (12.93mm x 1.86mm). I found these to be cheaper at Ford. Make sure you coat the O-Rings with some PAG oil to help them slide into and seat better in the fittings.

 

That line apparently needs a 1/2" quick disconnect tool. I bought the smaller set but 7/16" is as big as it goes. It looks like the line enlarges there from 7/16" to 1/2" to allow the filter to fit.

As far as location for the filter goes, wouldn't putting it post-compressor, but pre-condenser prevent the new condenser from becoming re-contaminated?

I could understand post-condenser if it hadn't been replaced, then the filter would catch contaminates that were working their way out of the condenser.

Just a thought, I'm trying to make sense of this.

 

Here's a good read/explanation (better than I could explain with a keyboard) as to why filters are installed on the liquid line.

Orifice Tubes and Expansion valves... auto A/C diagnosis, repair & troubleshooting help

 

Thanks for your help, I'm glad I checked that rear filter, it was 100% plugged, just like the Orifice filter.


One more flush and I should be ready to start closing up the lines.

 

Been there...Done that...If you read my post about me replacing my compressor, you'll see that it took 3 live flushes to get all of the debris out of the system. I believe that the debris I got out was from the line muffler(s). These are the cans located in the rubber hoses (1 High, 1 Low side). They are non flushable (so they say, but I did mine anyways. I suspect crud was in the high side one as any crud going towards the low side one should have been stopped by the front orifice filter and the rear expansion valve filter.
