Ref. our 75 F-150 with a 390.

Question: Is the A.C. compressor mounted standing up or on it's side?
If on it's side, the tubular brace connects to…?

 

Here's my '75. The brace goes from the compressor to the exhaust manifold.

 

79 Bronco 351M C-6 trans, compressor mounts on its side. No brace.

 

That's great advice for the guy....or was that an attempt to be funny?

If so that was a FAIL.

I guess we should just agree to disagree, on everything.......and let it be.

 

If you are using stock AC hoses, I'm guessing they will only work with the compressor mounted correctly. The suction line probably wouldn't care, but the discharge line to the condenser probably wont reach if it's mounted wrong.

If you're having the hoses made, or the stock ones actually reach, it wont matter how you mount it.

 

All 4 of our vehicles have ac. My wife has had hot flashes since 09. She won't ride
with me without ac. We are in the Milwaukee area. 2012 was a hot year.
Original question: My compressor is vertical. Is that correct? Should I attempt to
remount it horizontal ? (without breaking a seal)

 

You should be able to mount it horizontal if you want. The lines should rotate with no issues.

 

From the factory the compressor was mounted in the vertical position.

 

Thank You. Next problem is loosening a header bolt for the tubular brace.
I have a brace to reach the 1st or 2nd bolt. However, even with lots of soaking with
various sprays and even a hand torch, neither one will brake loose.
Any sure fire solutions?

 

Have you tried "freeze off" or any other cold break free trick?

You do not want to break either one, they are a major PITA with the steering shaft, shock tower and maybe a 1/2 coil spring bucket in the way, if you have it drill out.

Drill bits and easy outs brake too....ask me how I know....

Bad day goes worse there is always a "helicoil". If you can get the busted piece out and get it some what drilled.

I have better luck with a cold versus hot removal.
