How to remove A/C compressor hoses?

[1batt4u]

I was wondering how do you remove the A/C hoses going from A/C compressor under car, between frame, fiberglass body to front of car.

Since I am putting a new A/C compressor and upgrading to R134 do I have to put new hoses in as well or just use the same old hoses?

Easy - Cut the end off an pull it out. Getting the new ones in is the fun part.

I thought of that, just wanted to ask.

How would I get the new ones in?

You either get the split ones that some vendors sell, or you have to lift the body from the frame. About an inch I think should be enough. Every car is a little different of course so some are going to be easier and some will be harder.

Has anyone ever examined running the hoses a different route so that the body need not be lifted? Not the purists, but the rest of us? Hell, I've rerouted the cooling system, engine wiring, fuel filter and engine fuel lines, so why not AC hoses?

If your old R-12 hoses aren't leaking or worn then there is really no reason to replace them when converting to R134a. If you are wanting to change hoses because they don't fit your new compressor, then be aware that there is a specific Sanden R134a compressor that is a "drop-in" replacement with the same hose connections, mounting config etc. as the old SD-510, discussed here:

The frame hangs a little lower when you lift the underbody, and should give clearance to get the hoses in and out. Having access to a lift really helps, so you can stand firmly and shove the hoses around.

I went the split hoses from PJ Grady. I also installed shorter bolts on the fuel tank in some locations, so there is no risk of the bolts rubbing or puncturing the hoses.

Ok got them out!

It was a killer cutting them with a blade. I grabbed my saw and just cut through it easily.

When I did this, oil came out, looked like engine oil, dark brown. Is that normal?

Compressor lubricant. Normal, but be sure you flush it out of all the remaining components before you replace the hoses...
