6.7 A/C Compressor Failure
Hey Guys,
I just had the pleasure of swapping out my A/C compressor.....and it really was not that bad. Good news, you do not need to remove the fan. When I got home last night I could hear a bearing going out some where, it sounded like a roller skate wheel. I checked my belt area and found the tensioner looked like there was some damage to it. I figured it was the problem. After removing it I was able to see the A/C compressor wheel was wobbly and in bad shape. A new one cost $ 486
To take the belt off all you need is to disconnect fan cable and hardware from the fan clutch. See PDF.
With that free you can use a 3/8" breaker bar turning it clock wise on the tensioner to release the belt. The belt is LONG and expensive, I think around $140ish but it was time for me to replace mine. I have 137,000 on the clock.
If you have to replace your pulley tensioner, it's a 15mm bolt holding it.
To remove the A/C compressor you remove the air intake box & pipe. Discount the compressor cable.
Vacuum the Freon out of the A/C System.
From underneath you can access and remove three 10mm bolts that holds the compress to the motor.
Remove the two 13mm bolts holding the Freon lines to the compressor.
The unit will now drop down and you can fish it out the bottom.
Unbolt the top bolt 19mm on each sway bar end link and you can push it up and now the compress will come out.
Install in reverse order. The fun part is installing the belt back on.
Overall the job was a piece of cheese wiz. I read that changing the compressor on the 6.0 was a pain, the 6.7 can be done under two hours.

I don't think it was your fault, I think there was a batch of bad ones installed at the factory perhaps without oil. I did not have a leakage issue, my compressor looked like it never had oil in it or not enough. Another funny thing, my condenser post dated the manufacturing date of the truck????? Go figure. All in all, its been a good machine and now has 130K of hard business related miles on and still runs like new.

Sorry to dig this up from the dead, but I am doing this same job, along with a evaporator replacement. I want to replace the desiccant and screen that is normally in the receiver/accumulator, but I can't find it. Anyone have any idea where Ford moved it to on the 6.7? This is driving me nuts.
Thanks in advance.
Thanks in advance.
