Question on converting over AC

[GreenMonster]

Hey guys,,, I just got my K5 a couple of weeks ago and i want to convert/charge my Ac system. My questiuon is on a 91 where are the high and low presseure hookups. I'm guessing the huigh pressure is the one on the canister near the firewall...is the low pressure the one that comes our of the condensor and runs along the frame up to where the radiator is mounted? Any help would be appreciated..it gets real hot real quick out here.

You got it backwards.
Low pressure is the drier side "cannister" and the high side is the condensor side.

Your post is titled "question on converting over AC". Is this to mean that you are going to switch out R12 to R134A?

The cost and effectiveness may not be worth the changeover. The condenser is not really set up for the R134A. You really need a parallel type condenser for the R134A. You may get it to work but it will be limited.

You will have to have the system evacuated by a shop to capture the R12 before opening the system up. You need flush it out and change out all the o-rings and buy some new stuff..

Just friendly advice - if you are unsure which is the high side and which is the low side, you should probably avoid doing any AC work yourself. If done incorrectly, you could be out some serious $$$.
