Replacing AC components

My 2000 GTP compressor is making a ton of noise when both on and off, and I have no cold air. It will stay cool for a week if I put a can of refrigerant in there, and then fade back to hot.

I have a new compressor, accumulator, and orifice tube on the way and need to know if there's anything else I should replace at the same time? The compressor indicates that it comes with the seals and rings. Any other seals or o-rings I might need?

Also with regards to flushing. Since it hasn't locked up, do I need to flush before installing or should I be okay with just doing a flush after all the new components are in place?

Thanks,
Steve
 


Flush it before you install the new stuff, it's worth the cost versus putting all the new stuff on and having some crap in the condenser that causes you problems later.
 
Can u use water to flush the condenser..?? I got a use one awhile back and water was use to flush it before installing it
 
No, never use water.

Its best to use a real AC machine to suck out all the freon, then do the work, then have it tested again to make sure it can hold the vacuum, then recharge qith 1.88 lbs
 


I see you aimed for the orifice tube. Good call. Here's what they can look like

I'd do the rest of the underhood seals while you were there. A seal kit is cheap insurance against leaks.
 
I originally thought my A/C going hot was a problem with the compressor. Turns out thanks to some UV freon that there is a leak around the high pressure valves where you plug your gauges in when recharging the A/C. We are going to replace them this weekend after we use our vacuum to collect the freon that hasn't leaked out.
 
Turns out replacing the high pressure valves didn't get rid of the leak. But it did slow it down. We have used ultraviolet freon and a freon detector and nothing. We can't think of anything else that we can do besides taking it to the dealer.
 


The evaporator is housed inside the car behind the dash. If you're not seeing any leaks in the engine bay, maybe the leak is coming from there? Good luck getting to it though. From what I can tell it requires removing the whole dash.
