A/C parts for Denso
So, all my R12 leaked out and I took my car to a shop that specializes in classic car A/C systems. They tell me that it's leaking all over the evaporator and that they need to replace the evap, dryer and expansion valve.
Not unusual to hear that--I think most pro A/C folks will always say that you should replace the dryer if the system has leaked, and I'd gladly replace all these bits, except that I can only source the dryer from Ray and the other parts, while listed on sites online, aren't actually coming up as available.
Does anyone know if the Denso parts are actually really available anywhere? Brody8877 reported that they're available in this recent thread, but the shop called Mazda and Mazda said they don't have them, and again, Ray said he can only get the dryer.
Kensin, I know you're doing a bunch of A/C work right now--did you source new parts or are you just going with what you've already got?
Should I not be bothering with all new parts? This shop didn't give me the option to just replace o-rings or what not--they stated instead that the parts need to be replaced.
Thanks for any thoughts on this.

You can find the driers new on ebay fairly often. I priced out all the denso pieces and a lot of them were NLA.
The problem with converting to a MANA, is the evap is different in the system, so you have to remove it all from the dash. The lines differ as well. There was a big comparison on it somewhere on the board. Just do a search for Mana vs Denso or something of the like.
You could go to a different shop...
I bought a new OEM compressor to swap into my system and I'm having custom lines made with a universal drier. I'll be using the oem lines that run up to the condenser, though.

Hey man sorry to hear that it's also happening to you . It's hot as hell in CA and our ac system decides to dump us lol
Anyways. You say you have R12? So you have a mana system. Not denso. And most parts for mana are long gone. Especially the drier. So far i was able to get a new factory pressure relive valve new. I am currently searching for new mana expansion valve aswell. Ray dose not sell them. I may have a few in need to verify with daleclark. I'm basically fixing as I go. I have an unusual high operating pressure on the high side. Most likely a clog some where since my fan is working properly.

Hmm, are you sure about that? Everything I've read here tells me that the factory-installed systems are all Denso, and that all the Touring models were factory-installed, and that if I have a silver dryer, that that also indicates a Denso system. Here's the thread that I think led me to this conclusion.
Sucks that yours isn't working, hope you find the parts you need! Mine luckily still works just fine--it's blowing cold right now--but it is leaking. It leaked out the previous charge within I'd say 11 months and about 2000 miles.
LOL yeah I hear ya--by the smudges on my glove box, it certainly looks to me like he looked under the dash and confirmed it visually--that's what he told me, that he refilled the system and saw it leaking refrigerant very badly out of the evaporator.
Maybe I should get a second opinion? I just hate dealing with AC systems.

i got confused for a second cause i thought all MANA was R12. and denso r134a
i guess denso system both had R12 and R134A.
if thats the case. the parts you need are still purchasable through other same era cars then i would think. i might be wrong. wait till others chime in

Canada, eh
Watch for denso compressors coming up in Canada. I sold off my two spares, and of course, my compressor clutch breaks up shortly thereafter.
However, we have a steady flow of JDM coming in and often folk are (unwisely) deleting the ac. So compressors (and other bits) do come up.
I am searching for one for myself atm. Perhaps I'll come across several.
My mechanic warned that my compressor might have seized and could have sent shreads of metal into the system. He will do a flush when he replaces the compressor.

Thanks Dale, just read your thread.
So, I definitely have a Denso system. I think my last question for this thread is: is it common to have to replace these parts? I assume leaks would just occur at a fitting, unless there's a crack in a line or some other physical trauma. When I took it in for service, I was expecting that the shop would just want to replace all the o-rings and maybe want to replace the dryer, so it threw me off when he said I needed the evaporator, expansion valve and dryer.

Evaporator leaks aren't common. Not saying it isn't possible, though. It typically takes physical damage to get it to leak. It may be a leaking O-ring or something in there. Regardless you may want to get a second opinion.
The drier is like the filter for the AC system, it's a good idea to replace whenever it's open.

I don't think there's anything AC wise that you need to pull the dash for. The evaporator comes out with the dash in place, there is a 10mm nut on the top that will need a long extension but it WILL come out.
Heater core or anything associated with it will need a dash pull, but not any of the systems that have AC refrigerant running through them.
