oil help pag?poe?

clubvanman on Fri April 11, 2008 5:45 PM User is offline

Year: 1991
Make: ford
Model: e250 club wagon
Engine Size: 460
Refrigerant Type: r12,freeze12
Country of Origin: United States

Just doing conversion to 134a. Flushing all components per these forums. Replace o'rings,compressor,exp. valve on rear unit,orifice tube.accum.,ect. I have both POE (Texaco hfc100) and PAG DEC 46 per the compressor rebuilder. It has a muffler on the high side from compressor to condensor and I think I read not to flush this part. Any other comments or help would be appreciated especially on the oil to use.

Be sure all flush material is out of the system..when you think it's gone, do it again.. I would use the Texaco HFC 100 myself.. If using PAG the 46 viscosity is the one... Don't flush thru mufflers, either change them or use compressed air to blow them out..Hope this helps..

Opps, just noticed you're using Freeze 12, (80% R134a anyway) do not use PAG,,You'll ruin the system.. Why not R134a???

Blowing air thru a muffler will do little to remove contaminations. Better to simply replace the hose assm. As one can see with this muffler, it would indeed be a canidate for possible flushing..however, a personal preference would be to replace...a few more bucks...but in the long run may save a compressor.

This was a flush job...and then cut. The only way to know for sure it is clean...is of course...cut the darn thing open....but then..much easier to simply replace the units.

Thanks for the input guys...The freeze 12 is being replaced with 134a along with all the other components above. I am leaning to the POE for the oil replacement. Also have any of you ever use the BG product "Frigi-quiet" that I have heard good things about?

Always need help.....seems like everything is going south these days......esp my mind.
Perhaps, I shall try once more.....maybe even get it right this time......was in a hotel in CA...internet was so darn slow......but then....as in most cases...was probably the fault of the 'installer'.....
How are you these days....the trip to AZ was cancelled.....but headed that way next week...however, they have me booked each nite....Mon-Thurs....if possible perhaps lunch would work. Will check the schedule...see where I am going to be each day.....give ya a call on Monday....see whats going on.

Hey there is a fitting with an O-Ring behind the front bumper that is a real bugger to get to. Make sure that you replace the
O-ring while the system is empty or it will leak when you don't expect it and you will get to redo the job again.

I have the condensor completely out of van and will be replacing all o'rings with it...Are you referring to these or some other? ...no other lines at the front bumper that I can find !!!
