Listen, my understanding of this forum is to help one another, not try to get the last word. If you read my post, I was addressing someone else other than you. I asked them, if they used this procedure on a V8, why dont we start with you telling me what the difference is between the two compressors? I am a very logical person, I couldn't see a V6 having a completely different compressor for the A/C than the V8, unless you have a logical explanation. I don't know how old you are but the bickering has to stop. This is a public forum, newbee or not.
Additionally, as pointed out - the TSB only applies to the V6 compressors. If your mechanically inclined - take out your compressor (it's a PITA) and switch the spring out and report back... maybe you'll get lucky...

To Brutals point:
New style compressor on left, 2005 OEM on right

BTW in the V6/V8 comparison picture, the compressor I picked up (the first one) did not come with spacers. I did in fact think about making my own but I found the correct OEM compressor online cheaper than the "short" bolt guide one.

To answer your question, Yes this was on my 2003 S type R, per the TSB my VIN does not fall into the range of the affected cars but the quick repair worked like a champ and continues to do so today. I purchased a Ford Motorcraft compressor to just change the thing out wound up not being needed after the tsb repair. The left side of the engine has to be raised to remove the compressor also so that was another reason to at least try the tsb repair

Glad to see this thread is alive and kicking, makes me really feel good that I signed up! Anyhow, I havnt looked under the car in a while, I dont know what kind of compressor I have, all I know is 4.0L V8 2000 S-type, I am definetly going to check this out before the heat arrives, btw, is it easy to remove the compressor? Would I need to lift the motor to do it? Hope not if so, I am just going to have to bear it out because that is not what I am about to do.

With the age and miles on your 2000 I would replace the compressor. Have you looked at the compressor? Check for yellow stains and drips. This is the refrigerate oil. The way the S Type A/C is designed the compressor is the lowest part of the system so the oil will by gravity puddle at the bottom of the compressor. These compressors tend to leak where the case is split for assembly. I have been told this is not repairable and is very common.
I got a brand new Chinese made AC compressor for about $200 with shipping on EBay. This also included the dryer and the expansion valve. Be sure to vacuum down the system good and replace the dryer. I would not mess with attempting to change the expansion valve because it's buried in the dash. No trade in or core charge either! You can search for Lincoln LS AC compressor to find it. I have been running it about 2500 miles so far without problems. I asked the seller how these were lasting and he claims only a couple returns out of several hundred compressors.
I don't think you need to raise the engine to replace the AC compressor. On my 2003 LS the compressor can be removed and installed without raising the engine. The top rear bolt cannot be removed or installed completely so it must be put loose in the compressor hole before you slide the compressor back into position. DO NOT forget this!! And do not ask how I know this! I spent a good bit more time than needed because of that fact.
The STR for sure and maybe the other 2003 and up S Types do require you to raise the engine because the front sub frame was changed and an added cross brace blocks the AC compressor access. Much more work to change compared to the early 1999-2002 S Type!

Not too sure on the early models but on my 03 there is no way to get the compressor or all of the bolts for that matter out without raising the drivers side of the motor, the instructions i recall tell you to loosen the bolts on the drivers motor mount and use some insanely priced specialty tool / lift bar contraption to raise the one side. As for the compressor, if you want new not reman. look up the comparable year / motor of the LS and purchase the Ford Motorcraft compressor hundreds less than the Jag unit.

Every Repair Shop I have been to has been over pricing my labor. I cannot afford to go to these places for work, simply dont trust anyone. They look at the car as a "Very difficult" project, even though this year is a ford model. I hope to God I dont have to life a motor to replace the compressor otherwise, I will just keep burning in the summer. At least the heater is fixed now its cold.

Additionally, if you can find a shop that will allow you to bring your parts in - that will help you save $$$ (from shop mark up) as well but they'll more than likely bump up on labor charges and not guarantee the parts you bring...
