Tools needed:
13mm wrench
17mm wrench
A/C Removal Tools


You want to start by discharging the system. There is a schrader valve on one of the main lines by the heater core.

The accumulator is located on the passenger frame rail, right below the battery. It has one harness and two large lines going into it. Remove the two clips and unplug the harness. Use the proper AC removal tool, and force the two lines off. Each has 3 O-rings each that should be replaced.





There are three 13mm bolts, one is easily accessible on the bottom of the frame rail and the other two are facing the motor. Once removed the accumulator will drop right out the bottom. The harness plug on the accumulator can be reused on the new accumulator, it takes a 17mm wrench and also has a small O-ring.



Replace the old one with the new accumulator. Motorcraft ones can be bought from Rockauto.com for around $70. Wrench the new one on and push the lines back in, and don't forget to replace the clips and harness.


Supposedly you should not leave an AC system open to the atmosphere, but with a proper flush and refill by a trained professional you shouldn't have a problem. I never have.

Nice write-up, glad to see one done for the '03+ seeing as the fill ports are not on the accumulators.

Just wanted to say a big THANK YOU.
This is why I love CVN.
Even though I am upset that I found green liquid on my garage floor last week, and today found that my A/C was not working.
I searched here and BAM, my answer appears, all is good in the universe again. Now I just have to order a drier (found one from Tasca Ford in RI for $57.05).

Ordered with $10 shipping UPS.
I did look at the sponsored links first but this was cheaper and OEM Motorcraft.

Thanks again Tony07 and all those that post their finding to help keep our panthers on the road.

NOTE: do yourself a favor, don't buy those OEM plastic rings
if the quick disconnects have coroded at all they wont work very well
after tons of PB blaster and modifying the clip to force the spring out i finally got the "quick" disconnect free
hours in 105* humid weather is not fun fighting ONE connection frown

you should drill a hole in the bottom of the accumulator and drain what ever oil that is in it out into a measuring cup then add that much oil to the new accumulator before installing it. don't reuse the old oil and clean the measuring cup before measuring the new oil

or, bring it to a shop and have them oil it when they fill it after vacuuming it out

Some questions on this:

1. On my 2005 the lines going into the dryer have a plastic coating around the pipes where they go into the dryer - almost like shrinking over a wire but of course this is shrinking over the pipes - should I cut them to remove the pipes?

2. Would I use the same tool as pictured to remove the pipes?

3. Is there a part number or website or store to get replacement O-Rings?

Note - it also looks like four clips need to be removed to remove the dryer itself from the plastic housing...

Thanks!

I answered my own questions - here's a video on how to use the quick connect tool to remove the accumulator/dryer lines:

Just out of curiosity for those of you who have replaced the accumulator yourselves and paid for the evac, leak test, recharge:

How much are shops charging?

I've gotten a couple "over the phone quotes" for between $109 and $160. Some include the oil w/dye, some charge a bit extra for that.

$50 + "freon".

I did my 96 LTC last weekend.
Compressor was knocking but still had "freon".
I had the shop evac the system, then I did R&R on the compressor, "drier", o-tube and lines. I flushed all the lines and the evap and condensor. I replaced all the o-rings. I added the oil.

Shop said it was overfilled when they evacuated it so I did not have to pay for any "freon" on the recharge.

They basically charged me for the standard AC service they offer.

They charge $25/lb for R134a so $109 sounds like a decent number if it includes "freon". $160 is a little high.
