QuestionI have a 97 Toyota Rav4 and a local shop has said my compressor needs to be replaced, but they want way too much money. I am going to have a professional evacuate the system, then I will replace the parts, then have it filled by a professional. My question is, what other parts do I need? Their estimate states a compressor kit including compressor, receiver/dryer, expansion valve, solvent flush chemicals, and o-rings. Is this all I need? Also, is the receiver/drier the same as an accumulator/drier?
AnswerGarrett,
First, the receiver-drier and the accumulator drier are two seperate entities. The accum. is on the low side of the system and prevents any liquid refrigerant from entering the compressor, the receiver is on the high side of the system and gives the liquid refrigerant a place to "back up into" when your expansion valve deems it not necessary to have as much flowing through it. You do need both of them, and please do not confuse them for each other. The receiver-drier will more than likely have a sight glass in the top of it (looks like what you would find in a door to see who is knocking)
It appears the kit includes everything except the compressor oil. Dependent upon which compressor you have it may come with it already in it, but if not, you can find it at any autozone/advance type store. I believe it is running about 10 bucks for an 8 ounce bottle. Again dependant upon what the compressor calls for, you should not need more than 1 bottle. When you fill the compressor, you will put the oil straight into the low side manifold connection, just make certain you rotate the clutch and pulley as you are adding it.
You will also need a flushing kit to use with your flushing chemicals. This kit typically runs about 40 bucks for a decent one, and you will need a bit of nitrogen to push the solvent/flush through the lines. MAKE CERTAIN you do not skip the flushing step though. Right now, if your compressor burnt out, you have millions of metal shavings sitting in your system. If you do not flush them out, your new compressor will last about 8 months (at the most) and you will be doing this again.
Other than that, just make sure as you reconnect everything you put a new o-ring on every connection, and tighten it down as best you can. I have walked many an individual through the process successfully, so if I can help out during, just let me know.
Just out of curiosity, what were they charging? For a 97 Rav4, I would charge in the neighborhood of 850. (all inclusive) There is more to it than just changing parts, keep that in mind.
I hope I was able to provide the assistance you needed. If so please remember to rate this answer. If I can do anything further now or in the future, do not hesitate to ask. Thank you for the question and good luck in everything.
