Re: 1988 corvette, don't understand what it's doing?

spoke too soon. Left some penetrating fluid on them for about an hour. Double wrenched it and after some serious grip strength exertion......pop! got both loose and dryer out. Drained the accumulator and there was actually oil in it! Unfortunately, what did come out of it wasn't too impressive. The ...

Re: 1988 corvette, don't understand what it's doing?

hmmmm, laid the condenser on teh bench and filled it with MEK. Didn't take a full liter. Maybe 3/4 liter.

I'll let that sit overnight and see what the morning brings.

trying to get accumulator out now.

Steel nuts and aluminum tube/fittings.......what the hell were they thinking?

Re: 1988 corvette, don't understand what it's doing?

1988 is a one year only part. Ecklers has it for $359 Part #: 25-106728-1 Replacement for OE #: 3096179 Sounds like a previous owner went down the Cliplight / ID path. Hopefully the evaporator is ok. that's an easy over 500 cad after all said and done. If I need it, I need it. But I'm going to see ...

Re: 1988 corvette, don't understand what it's doing?

I personally think you're wasting your time trying to flush that condenser. Corvettes were know for having lousy AC systems to start with. To bring the high side down, mist the condenser with a water hose. If the high side drops like a rock, you have possibly an air flow problem and you're not reje...

Re: 1988 corvette, don't understand what it's doing?

Might be a combination of a clogged condenser and a bad accumulator, possibly with loose desiccant beads floating around inside. As someone else mentioned, if you're seeing +/–400 PSI on the high side, the compressor is doing its job. With those kinds of pressures, don't forget to wear your PPE whe...

Re: 1988 corvette, don't understand what it's doing?

well, I thought I had it. Charged the system and as soon as the compressor started running, the low line went instant cold. I thought I had it with the orifice tube. But no, it didn't last. It ran cold for a few seconds, even started getting condensate on the line, then.......nothing. Went warm and ...

Re: 1988 corvette, don't understand what it's doing?

In addition to everything already mentioned, are you sure that you installed the OT facing the right way? yep. Just had it out again to confirm. The replacement orifice seemed to pass less air than the original when I tried to blow through it. So I cleaned the original and reinstalled it to see if ...

Re: 1988 corvette, don't understand what it's doing?

So I'm sitting here thinking about this. When the system was non operational, I did throw a quick can of top up stuff in the system to at least see if it ran. It did and it even frosted the low line, although minimal change in the vents. I starting to think whats wrong here has to be something I tou...

Re: 1988 corvette, don't understand what it's doing?

Hmmm - sounds like TOO MUCH refrigerant from your pressures??? I have no experience with that refrigerant; RedTek is R12a. This link states that it will require only about 35% of the same charge as R12 to get the same (or most likely better) results. https://www.allpar.com/forums/threads/messing-ar...
