Maybe I was too brief regarding my question about replacing my AC compressor. This is my first post. I am wondering does anyone have any insight into replacing the AC compressor on a 2002 F150 with 4wd, and 5.4l engine? Thanks in advance

If you have someone to evacuate the system after installation, great. If not have it done by the people who have the equipment. The compressor change out in its self can be difficult when working with the clutch, again special tools required. Otherwise, disconnect the belt, unplug the electrical connection to the clutch, remove the freon lines, and unbolt the compressor. To repeat myself, its not for the home mechanic to do. After assembly is done and before, JUST ADDING FREON, the system has to be evacuated into a vacuum state and leave is set for a short period of time to remove all moisture from the system (humidity). Hope this answers your question. Welcome to the Forum and your entries are right on tract.

Thanks Bill. Took a look under there and it looks really tight. The compressor has to be removed from underneath and maybe through passenger wheel well too. I can't see where the manifold is bolted to the housing either. Guess this is one I have to take in. I agree... out of my league.

Thanks again Bill

going a bit farther in this. I replaced the compressor, replaced the orifice filter , vacummed the sytem and started to add freon before i turned the sytem on. but it will only take less than 8 oz. I re-evacuated the sytem and same thing any thoughts?

This is to help out the newbie, the highjacker, oh well its all for fun. Shoto, I am not a pro and thus am not sure how they install freon. My method is old school. After the system is evacuated and you know it holds vacuum, jumper the cycling switch, and start engine, let the new compressor pull in the freon thru the low pressure line. My gauge set has the sight gauge built in to check for bubbles. By the way, years back all systems had their own sight gauge for this purpose, then came progress and there goes the DIY guy. Good luck to you and welcome to the fun, or is it the forum.

Just a note, if you have freon in the system, get somebody to evacuate the system prior to disassembly, freon hits your eye's and you'll need a dog to walk. Best to leave it to the pro's on this one.
