Seized Compressor - What needs to be changed?

Hey Yall!

Unfortunately, my compressor crapped the bed last summer and I have been driving around without it since. I have some time to get it changed and it's looking like a harder project

With that - I plan on purchasing the GDP AC kit from Rock Auto HERE. Since my compressor seized, will I need to replace the evaporator core behind the dash? There seems to be mixed opinions on here and I want to do it once and right, I don't want any lingering metal shavings camping in the system that affect it in the future. But I also don't want to rip the dash apart if its not necessay.

Anything else I should replace in the the process? Refrigerant hoses? Heater Core?

I plan on having the system charged by a shop after the install. I'd rather struggle with this over the next few days than pay the high dollar for the toatal fix.

 

Your avatar does not indicate your location but be aware that unless you have pulled some connector or fuse that every time you have selected defrost or bilevel on the mode control switch it is trying to activate the compressor that whole time as it runs on both, as well as on the AC mode.

My recommendation to you is don't start stockpiling parts unless you know the total extent of the problem.

However, there is nothing wrong with doing a preliminary search of sources and reviews of aftermarket parts if you are considering that. Don't consider cheap parts as work on the AC system is a big job and you want good parts or you may soon be doing this again.

The compressor could have seized without it also disintegrating internally, this is the best case.
On the other hand, the compressor could also have grenaded in which case it may have unleashed debris everywhere in the system and contaminated everything. Possibly every last part.

You said someone else was going to do part of the work. My recommendation to you is that AC work is no place for the inexperienced, especially if a compressor has failed, have an experienced person do the job or at least assist you. If they are an experienced AC pro they should be able to assess the components needing replaced be familiar with relatively reliable brands. The Toyota OEM seals are the best.

 

Thanks for the advice! I just dove into this project and wanted to wait to respond until I had something to report. I can't find any debris in the condenser, compressor, or lines......which seems like really good news! I went with a new GPD AC kit from Rock Auto. I almost have everything fully hooked up and ready to go!

I haven't been bale to use defrost or AC in over a year so it should be a delight if it works again lol. Thanks again!

 

I would flush out systm to be on safe side .One section at a time .

 

I finished the job a few weeks back and forgot to report back for anyone else looking to do the whole job....minus tearing the dash apart. I ended up not replacing the heater core but went ahead and changed all the refrigerant hoses.

I bought the GPD kit off Rock Auto and it worked well - No dash removal was needed! I had absolutely no signs of debris or metal in the system. The old compressor had no oil in it after I removed it so I am guessing that led to failure. Some general pointers for the job:

• Order Fours Seasons Hoses off RockAuto - GPD Hoses did NOT fit correctly. I tried to save a few bucks and it bit me in the butt.
• The compressor should fit through the wheel well if you play around with it.
• You can access the expansion valve through the firewall easily
• Make sure to buy a NEW orifice tube! They are cheap and they don't come in the kit

 

Did you replace the accumulator? Usually a requirement for warranty on the compressor.

 

The Condensor + Drier is a single unit on my 06 so the whole thing got swapped out with the kit!

 

Kind of like a 2 stroke the oil travels through out the entire system.

 

Did this on my son's car a few years back. For the money you save, you can buy a vacuum pump and gage kit from Harbor Freight. I've used the gage set several times since.
There are a lot of good videos on YT that show how to use the gages.

 

u supposed to flush clean the circuit

if not, say Bye-Bye to $1000+ new A/C compressor within 1 year
