any one knows where can I find a car's A/C system flush kit for R134 gas A/C system?

and how to use that flush kit?

can I use that flush kit with the A/C compressor connected or I have to disconnect it?

a car's electrician told me if the compressor is connected and then flushing the A/C system after that the compressor will get damaged, is that correct?

thanks for help.

There is two types of AC flush procedures. One is to evacutae the system and open up the system and pour a bottle of the caustic *** solution in the lines and let it work it's way through and then blow the system out with compressed air, then seal it all back up and put it into a vacuum for for a while before recharging. The other is, lots of shop's have a dedicated AC flush machine that forces chemical and **** through the system and then gets it all out.

OK, thank you. I have a an A/C flush kit that I bought from ebay, I will read the instructions on that flush kit.

I will let you what will happen if I don't forget.

thanks.

when flushing the A/C system of a car do I need to disconnect the compressor?

I've always just popped lines off at the condenser or dryer. Why are you flushing, did you have component failure?

I have not had a failure in the A/C system before, I want to flush the A/C system to have more efficient cooling.

Whats the temp outside when you are checking pressure? Makes a difference on your readings.

This ^^^ plus humidity also plays a factor. Usually flushes are used when a compressor bites the dust and sends **** all through the system. Might just need a good charge and clean out the condenser fins so it can efficiently get rid of the heat.

use care some components are throw away
flat tube high efficiency condensers come to mind.
YMMV

Flushing doesn't help efficiency on a working system. What are your high and low pressure readings? Has work been done in the past? If so, someone could have over charged it with oil causing inefficiency. A dirt clogged evaporator coil causes inefficiency. There are other factors that can cause in efficiency. We need running pressures to help determine inefficiency.
