How to flush the ac system when installing a new compresser on a 95 Buick regal 3.8l?
Re: How To Ac flushing
Flushing the ac system will take special tools.
when replacing a compressor you will need to also replace the accumulator, oriface tube. When your compressor gets worn it starts sending pieces into the compressor stream. These tiny bits and pieces will travel into the condenser and then into the oriface tube. When you pull the oriface tube you should see how bad it gets clogged with debris. When you remove the compressor, the accumulator and the oriface tube, you use AC flushing fluid into the lines and push the fluid through the lines. (usually in the reverse direction) There are some tools that will pump the liquid through as a liquid and then captures the liquid and debris on the other end of the open system. Some tools use compressed air to push the fluid through and you need to cover the other end of the open system with a rag or something to capture the fluid and debris coming out the reverse end of the open system, You want to backflush the entire system while the compressor, oriface tube and accumulator are out of the system. When you decide that the system is cleaned of debris, use compressed aid to push all the flush fluid out and dry the system out.
when you go to install the compressor and other parts to will need to add oil to the accumulator, add some to the condenser and follow the directions for adding oil to the compressor. Some compressors come filled with oil others come empty. You will need to look at the instructions for your particular compressor. Regardless of your compressor instructions, you should always measure how much oil you can take out of the old compressor. It will be the best measurement of the oil that should be left in the new compressor. If the amount recovered is less than a certain amount, the instructions for the new compressor should tell you the minimum amount you should add to the new compressor.

Re: How To Ac flushing
I found a straightforward procedure on how to perform AC flushing;
Step 1: Take it Apart
The first step is to effectively dismantle your air conditioner, giving you greater access to the vehicle’s inner workings and allowing you to flush out whatever dirt and debris have accumulated. Take out hoses, evaporators, condensers or any air conditioning parts you happen to spot.
Step 2: Flush it Out
Next, flush out debris by using an aerosol air conditioning flush. Flush out each individual piece of the system, allowing dirt and debris to come out one end, then wipe each of them down with a clean cloth.
Step 3: Search the Ducts
The next step is to investigate the ducts, which should look like large tubes that stem from the zig-zag tubes of your evaporator. What you’re looking for here are leaks. If you spot any holes, use duct tape to patch things up. You don’t want any air leaking out if you can help it.
Step 4: Remove the Accumulator
The accumulator will be shaped like a coffee can. Its role in the engine is to sift out debris and condensation from the air as it prepares to enter your vehicle. But this filtration system gets bogged down over time and is likely the cause of all the dust and debris build-up, so it will need to be replaced.
Step 5: Replace the Accumulator
Next, you’ll want to purchase a brand new, clean accumulator. You can find one at any auto parts store, but make sure you have the one that matches your vehicle make and model. Installation should be fairly easy: Bolt it just like the old one was bolted, and then re-attach all the hoses and other connecting parts.
Thanks
