Why do you want to flush the A/C system? You shouldn't have to flush it, just add to it. Your car uses the newer R134a refridgerant, so there is no need for a flush. Cars pre 1996 used freon or R12, those car need to be evacuated of the old to replace with the new R134a.

I agree with Tom, you should not have to flush the system. The process is to recharge the system. I have not tried the diy kit but I would ask a "reliable" mechanic if he would recommend it. I know such a mechanic in San Marcos, CA and he will give you the correct answer with experience to back the answer. His name is Rusty and he works at Alliance transmissions. He helped me with my 05 Durango and saved me more than a thousand in repairs elsewhere.


The reason I am told, that I need to flush it is that there are contaminants in the system from when the first (and possibly second) air compressors blew out. My mechanic confirmed that when he discharged it a few weeks ago.

you definitely have to flush the a/c system, a little of explanation: your a/c compressor is actually a piston that is compressing freon, and just like any metal it would have some kind of wear (tiny metals) you should only flush your a/c system when something series have occurred to it, like a compressor gone bad. If you put a new compressor with out flushing it the trash (metals) trap in the lines are going to be transferred to the new one if not rendering your a/c compressor bad, at least is going to give you poor cooling, so with that been said, when you replace your a/c compressor (about $500) you also replace your accumulator (filter) and your expansion valve that is located on the evaporator, and in order to get to your evaporator you have to removed the glove compartment (that has an air bag in it) it is quite a job to take on, so my suggestion is that if you are not a mechanic, not even try to do it yourself, find a good mechanic (honest) becouse they can take you for a very expensive ride and tell your they replaced all this parts and didn`t so please be careful. you can try to add refrigerant your self but that`s it, no more, good luck to you, expect to spend about 1500 dollars on it.
