air conditioning compressor

Yes, all you need to do is loosen the manifold bolt about 1/4 inch and the manifold lift off the bolt. The manifold is like eyeglass, the noise piece is where the bolt rest on. Prelude the o rings with AC oil.

I'm currently replacing all of the o-rings in my system('97 5.0). Do I have to remove the compressor to get to those o-ring,

Yes exactly. The old kind were two pieces and had two bolts to hold them together. That looks like a new design that would be much easier to install, and likely still hold as well.


Here's one on Amazon that is a different part number, a different size. But the picture is the two piece type I am familiar with. The listings I see don't tell you what size they are, which is very important for each vehicle. Most older Fords had 3-4 of those connections, and mine needed three different sized clamps.

I will be buying a t least 4 of these

Thank you. Thankfully I already got this accomplished. The system was still holding a vacuum when I walked away from it this evening. Hopefully it will still be the same when I get back out to it in the morning.

Quick Tip: When your A/C is up to snuff, feel which hoses have cold refrigerant going through them, and "wrap" them in "closed cell" pipe insulation. Closed Cell insulation is the variety that feels like rubber. The result - you will bask in frigid air even traveling through Death Valley.

I did do this btw

What size insulation did you use and where did you get it?

I'm not sure

Homedepot, Lowes, plumbing supply house stock it. Brand name armor flex. People call it by many different names. Armacell, k-flex, Everbuilt: rubber pipe insulation. Measure the pipe diameter.

@Lee's Automotive

Home Depot & Lowes have it at the lowest price.

If memory serves me correctly I purchased 3/4" I.D.

Throw a set of calipers on your lines to confirm -

Make sure you get the one that feels like rubber (closed cell).

The other type - open cell - and they are two completely different type of textures so it's easy to separate one type from another

The open cell variety will disintegrate in a year or two.

Thanks what did you use for the accumulator to wrap it

I re-use the original wrap. You can buy foam tape for the pipe insulation. They offer it in a roll about 2 inches wide.

Description​

Ap Armaflex Black Lapseal Tape 2" X 81.8' - 12 Roll.
Some people don't re install insulation on the accumulator, because some model years there was a issue with rusting thru the accumulator.

Yeah mine doesn't have any of the insulation anymore due to field mice

No problem - the very thin foam wrap from the factory sucks big time compared to the thick & high-quality wrap you buy 20 years later from Lowes & Home Depot.

For the accumulator, I used the same 3/4 I.D. Pipe Wrap I wrapped the lines with.

Check it out - one edge of the pipe wrap has an adhesive edge, and the other edge is bare.

The adhesive edge is serious stuff - you pull a cellophane edge off of it to expose the super sticky adhesive.

OK - so I cut 5 or 6 sections of wrap the same length as the accumulator.

Than I let the adhesive edge on one length mate up to the edge of another length that didn't have adhesive.

I intertwined the sections of pipe wrap via that method so that they circled the entire circumference of the accumulator.

I "fed" the "foam blanket" around the circumference of the accumulator, and when it the accumulator was encircled, I peeled the cellophane off of the last section and let it mate up with the last bare edge of pipe wrap.

For good measure, I then added zip ties top, middle and bottom so the ""foam blanket" didn't slip off.

When I was done with insulating the whole system, my A/C got so cold face would freeze and my eyes would water.

I literally had to move the vents so that the air wouldn't hit my face - and this was occurring on 100 degree days.

Hope that helps -

Thanks so much that helps I'll be doing that this week sometime

Let us know how it turns out - do a before and after with a vent thermometer

I used to permanently leave a vent thermometer in the center vent so I could compare the A/C air temp coming out VS the outside temps.

My Ex was able to get down in the low 40's on days over 100 degrees -

I leave my digital thermometer in the center vent. Its a good check. You will know what is is and see any changes when they hsppen.

I did this repair in south Fl and replaced every part with a Ford part except for the evaporator that just could not source by motorcraft or Ford - I think it was 4 seasons - I’m running about 210/42 and about 59 degrees out of the vent - I’ve been slowly removing Freon as I think I overfilled it with some can filler issues and small mistakes - in 90 degree heat, 75 percent humidity and the south Fl sun this system is pretty challenged to give below 60 - maybe I’ll remove some additional Freon - or I’ve been thinking of adding a condensor fan ? Tried with just a shop fan and I got maybe 4 degrees lower

Your fine at that head pressure. 225. Compressor when full will run continuous from cycling. 42 psi for low is in the cold range. The vent temp , max fan , Recir cabin air temp should be in 40 degrees range. Your at 75 % humidity. There is a label on the radiator support which tell you the maximum amount Freon for the system ( 30 oz) 2 can 12oz should be fine. if you have moisture in the system the needles should be jumping around. When you first started you should have pull a vacuum for a hour at that humidity level. I am assuming all component are new. If you reusing the condenser that will effect performance. If so are the fin there?

 

[floridacatfan]

Maybe I have air trapped in the system or the duct measurement is wrong - I’ll keep working with it
