A/C Compressor lines
Guys,
I have a 1997 F-150 w/4.7L , The manual (Haynes and Chiltons, both) say remove the hoses from the compressor before removing it. The compressor is underneath and I can't see how to get to the bolts on the lines with out dropping the compressor down. Is there a better way?
Thanks,
George

I'm going to assume two things:
1. It's a 4.6 and not an engine transplanted from another vehicle.
2. The compressor is mounted the same on a 5.4 as it is on the 4.6.
If you can't get to the nuts holding the lines on, remove the 3 or 4 10mm head bolts attaching the compressor to the side of the engine. Yes, you'll need to lay under the truck to do it.
No insult intended here, but if you need a manual to remove the A/C compressor, then I have to assume you're not really mechanically inclined. Did you diagnose the need for a compressor? If it didn't kick on, the more likely cause is low refrigerant in the system. Also, you can't just replace the compressor yourself without a vacuum pump.

OK, just saw this post of your A/C issue and it seems you're on the right track. I wouldn't bother with replacing a compressor seal since it likely has 200k on the compressor.
