When I dropped in my 383, obviously the AC stuff was all disconnected. I havent driven the car much so hadn't bothered to get it recharged. The friend who installed the engine for me said to get a new AC drier since and then have the freon recharged.

Ive got the part, just want to know if there are any special instructions for installing it, or if anyone has a guide?

 

lube up the o rings put a few oz's of oil in the drier and screw it into place

 

Thanks,


what kind of oil?
just squirt it into one of the openings where the orings go?

also just thought of this, do i need to release any sort of pressure valve or something to disconnect the old one?
the system is all hooked up now, even though theres no freon in it and the drier was exposed.

 

yer drier should have come with an Oil my new one did, yes just dump some on each side where the orings are, no if their is no pressure in the system (no freon) you can take it off with out it popping off like a rocket im not sure if it takes a special oil or not

 

thanks, hopefully theres no pressure, lol. is there a way to check?

 

yea you know where to put the freon correct? if so push that stim down and see if anything comes out if nothing happens you got no pressure

 

a plastic cap on one of the hardlines right? if i remember theres 2 of them, and 1 is for input.

 

yea those are them

 

That new is R-134A right? Does the stem you gotta push in to see if theres pressure have a thread on type like a bike tire or something, or is it a quick connect type? If its thread on its R12 and need to convert to R134A *or pay like 150 per can if you magically find some R12 haha* But I do believe something that new would be 134A already

 

The connectors go on like an air fitting (quick connect), then you screw them down until they stop. You can still just push the valve in to see if it has pressure.

There are two schrader valves, one for high side, one for low. When you do a "backyard" recharge, you'll be tapping into the low side.

You're better off getting it recharged at a shop after you're done working on it, unless you have a machine to pull a vacuum on the system. You want to have all the air and moisture out of it before putting in new refrigerant. You'll be a lot less likely to have problems that way.

 

if you open up the AC system you MUST pull a vacuum on the entire system. By having just the dryer off you would have opened the system therefore needing a vaccum. By not running a vacuum on the system you risk clogging the system with anything that could have crept into the lines while it was open to the air/elements of any sort.

Don't they also have to somehow evacuate the moisture out of the system as well?

 

yes

 

yes, this is the main reason for pulling a vacuum on the system, to get the moisture out
