James89DX,

Thanks I plan on either using a clone or a original new sanden unit I have seen on ebay. The price between the two arent much different. I'm slowly collecting all the parts to switch over from my Matsushita.

v4lu3s

i have been using one for 2 summers now. works like stock.

Man I am glad to see this post. I have an 89 RT4WD wagon with the same issue. Clicking mostly at idle when hot. As soon as off idle it went away. Recently, I noticed that my refrigerant charge had dropped a bit and the clicking had continued beyond idle a bit. So, I think charge does have something to do with it. But, I am glad to see it is not a clutch issue or compressor issue. I am running Freeze12 refrigerant.

I had no idea a sanden bracket would be this hard to find. Nothing on ebay, and I've called every salvage yard within a 5 hour drive of me.

I've found aftermarket brackets, but so far only for B-series engines.

What year/models had the sanden? All 88-91 D16's? How do you ID them?

crxguy406

They look like this. The matsushita brackets look more like a solid plate.

Matsu vs sanden

Thanks guys, good info.

Thanks! Will keep that in mind!

Just curious what is the chinese company called? Where did you go to buy one?

rallypoint_1

This is my Sanden(esq) compressor. Been working great for the last 3 years.

James89DX

They're sold under many different brand names. The most ubiquitous is probably GPD brand. GPD is actually a pretty good quality Chinese clone manufacturer of all sorts of AC parts for almost every make/model vehicle. I think actually GPD probably manufacturers all the TR70 clones you see online. I have a buyautoparts.com TR70 and it's definitely just a GPD.

GPD is also called simply "Global" brand sometimes in listings. Their TR70 is # 7511558, which you should be able to get for under $350 shipped.

The problem is in the Protector Set, Thermal

This is where the Protector Set, Thermal lives. First remove all r134a.

I had to remove 6 screws to get it off 4 on the top and 2 long ones in the back then just give i a tap to brake it off.

I found alot of trash inside holding the valve open.

So i took it apart

Clean all the rocks

Put it back together and the pressure increase when i turned the clutch by hand.

I did a LOT of research on the noisy Matsushita compressor in my 89. I was never able to find any type of definitive reason for the noise. So, you are saying this part will fix the clicking noises? I would really like to hear more about this and how you know this might be the issue? Thanks!

Uh, if this fixes it, I'm definitely trying it. Did the system seem to perform better after you did this fix? Getting pretty damn annoying turning the AC off in drive throughs, and having people look at my damn car like it's falling apart lol.

sumdewd

You can't bump a 4 year old thread and not elaborate on the fix dude. I wanna hit taco bell with my half drunk roommates and keep my AC on

Did u ever change to evaporator? Because I just purchase a 30lb tank of Johnsen's freon, and I noticed that the low side pressure drops very slow almost like there's no vacuum. the AC get very cold temps show at under 30 very cold. I change the expansion valve,accumulator and the condensor the AC pump i had before did this same noise so i got the reman pump and the same noise again the only the thing that i see we both havent changed is the evaporator. Im going to change mind with a new evap and expansion valve in about a week from now 8-15-2019. YES 4 years old and still going. Lets fix this now

Pro Wilson

I notice when I overfilled the system it made a lot less ticking noise. I have to fill the system with the car off from the high side. when I try to fill from the low side with the car running AC compressor engage almost nothing goes in so that makes me think that the pump cannot pull a vacuum, but this cannot be so because the compressor still gets cold so it has pressure and with pressure you should pull a vacume unless the system has a block in it ... this means the ac will still get cold but have a hard time geting back to the pump.. But i could be crazy i have been massing with a lot of freon...lol

arries289

In my research I found the same thing. People have changed all the components (except the evaporator) and still had the issue on a reman pump. That is why I was so interested in your comment about the thermal protector above. So, you are saying that did not work??? I am a bit confused. I have also noticed my system gets a little quieter (takes more idle time and hotter temps) before the clacking starts. Its a perplexing problem using logical troubleshooting.. I am interested to find out what happens after you replace the evaporator. Please update this thread when you do. Thank you for your testing and updates.

Pro Wilson

No this did not fix it and same here it sucks having AC and cant use it especially after you spend about $700 to get a thing working..So trust me I feel your pain and im working on it. Something you may not know about me when I start working on something it will get fixed..

Update:: I think I may have just solved this puzzle. I think this particular compressor that comes with the 91 CIVIC and the CRX is ONLY compatible with R12. The reason why R134 has smaller molecules then R12 to my understanding R134 is passing through the expansion valve too fast that explains why my low side pressure is too high and why do not have a vacuum on the low side aka High head pressure.. I will still change the evaporator and see how that goes but i dont think is going to make a difference. Next im getting R12A.. Side Note One 6 ounce can of r12a Replacement Refrigerant is equivalent to 15 oz. of HFC-134a & 17 oz. of CFC-R12. If my math is right thats thats about 14oz of r12a, and u can get a 18oz can on ebay for about $19.00

Pro Wilson

okay so I change the evaporator today, and like I thought the ticking is still there. I do have better vent temps now and better air flow. It also smells like the inside of a new refrigerator, but no change with the ticking sound The last thing im going to try is R12A before I take the compressor out and disassemble it so I can see what's inside.

Honestly, don't waste your energy on the matsushita. It's much better to retrofit a Sanden TRS090 in these cars. From what I've read, you can use the AC bracket off of a 96-00 Civic with the d-series engine. The biggest issue is with making the custom hoses to fit the Sanden compressor. I just haven't gone about doing that yet with mine, and likely won't since this car is too old to be an effective daily driver in all reality.

I've already been through my car with R12, parallel flow condensers, 4 different matsushita compressors, 2 different evaporators and none have made a damn difference. It's a shitty rebuild since no other compressor I've ever used has made that noise.
