Default Replacing A/C lines on 1982

I need to replace A/C lines. Do not want to pull engine or radiator.
Need some good advice on getting to connections.

GOOD ADVICE.....Unless you know what you are doing when it comes to an air conditioning system....DO NOT MESS with it UNTIL you have a person who KNOWS about A/C systems look at it first. I honestly doubt you know what is going on due to asking for help in this.

If the system is still under pressure...it needs to be evacuated CORRECTLY...and NOT take a line off an let the Freon out.

I can write that the hood HAS to come off....and you may actually may need to replace more parts than the hose/line set-up. Which is why I would advise you to let someone you know who know about it look at it and advise you.

Dub,
You are 100% right. I don't have an idea of what is going on no more than I have a leak.
The A/C expert of 25 years that is working on the system ask me for information on how to access the connections. I was looking over his shoulder when the system was tested. With leak detection equipment in hand the only leak that was found is on the A/C line where the rubber connection and the hard line are made together. As you are aware trying to get to these connections is pretty tight. I hope everything else remains leak free.
I will remove the hood.
Anything else?
Jim

Sounds to me you only need a replacement hose or an AC shop to recrimp the fitting. Does the shop make AC hoses? When I blew a hose on my 74, the shop used my original ends and made a new hose.

Easy Mike,
The shop makes fittings.
The crimp is leaking on line from compressor to condenser.

You should also replace the Drier/accumulator, as there is a desicant bag contained within. This absorbs any water that condenses in the system. If the system is leaking as you say, it is open to atmosphere, and that desiccant is probably no good now.

About 60$, cheap insurance, free water fill destroy your compressor.

Bikergems:
If he is a n experienced A/C guy...then he already know that it will take either access from underneath for the accumulator or from the top and possible require removing the coolant overflow reservoir. Also having wrenches that have been cut shorter helps also. Depending on the line or part being replaced...it can be NO FUN....gosh knows I know about that. And installing a new hose assembly from the compressor to the other areas in the system....wrestling with it is also a bit of fun but is 'do-able'. I prefer installing a new hose if possible...and it is just more of a visual thing for me.

YES.,,..there are some companies that can crimp on a new hose but it might not look factory...which is why I prefer to buy a fresh new hose.... if I can get one.

CORRECT ...but also INCORRECT....WRONG SYSTEM.....the 1982 Air Condition system does not have a desiccant bag that you can change out.....this is in the earlier VIR systems....the 1982 Corvette has a CCOT (Clutch Cycling Orifice Tube) system.

If the system went completely out of Freon...I myself would change the accumulator...but that also depends on how long it went while being out of Freon. Pulling a vacuum on the system for some time will remove the moisture and make the system work....but I prefer to change it if possible.
