Already searched: Sub-zero assist removal?
Like the title said, I've searched already. I searched 2nd gen archives, FAQ page, and current forums. I've found that the sub-zero assist is free, easy, and does absolutely nothing negative to the car. However, I haven't found HOW exactly this is supposed to be done.
Seeing as dealers were apparently instructed to remove the sub-zero assist on all post-90 models of the FC, as it's useless, I'd like to remove mine from an 87.
I am paranoid that I'll do something to harm the car in some way, so I was hoping someone would be willing to write up a quick walk-through for those of us who haven't done it before.

Just pull it out. I think there are some 10mm bolts and a hose to undo, but other than that just yank it and stick it in your garage. Took me less than 2 mins to do when I put in my rebuild. If I recall it's easier if you move the charcoal canister out of the way first.

I have had mine system "disabled" by Mazda. Plug the hose and disconnect electric.
Another option is to get a block off plate and remove the entire system. (requires removing UIM for install of block off plate)

YAY THREAD NECROMANCY!
I do live in Ohio, but this car will be used only in above-freezing temperatures, unless I get stuck at school when it's snowing. Basically, I plan to put it away as soon as we get out first snow that necessitates road salt, and plan to get it back out as soon as the snow melts in the spring.
What are the advantages to getting rid of the sub-zero assist? also, what does it look like?

In fact I'd be shocked if the thing actually still worked. Generally it only took a year or two for the motor to corrode and lock up.Pull out the resevoir and hose, then cap the vacuum nipple. If you want to be thorough, cut the bracket off as well.

just called westcott Mazda in National City i know one of the managers there and he looked it up for me because i also have the subzero assist and wish to remove it. They will remove the system for about 150 dollars and they wont even put block off plates they will just plug the hose. so for 150 bucks i say **** it, i'll do it myself.

As has been covered many times, Mazda issued a TSB years ago instructing dealers to remove it.

Shops don't make money doing free repairs. If someone walked into your shop and said "This is the problem, I have diagnosed it myself. Please fix it." what would you do?
As for free repairs, I would think a recall would constitute a free update/removal of a part. I thought of it this way: What if the recalled part was something that COULD **** up an engine permanently?
Why even bother the dealer? Remove the reservoir (it slides off the bracket after disconnecting the wiring) and put a vacuum cap over the nipple on the manifold. Done and done.
It's kinda hard to remove it if I don't know where it is...

*not intending to be a jackass on the last post, Aaron.
While I see your logic that a dealership would not want to do free repairs, it also seems logical to me that if there was a recall, they should make good on it for free, like they would/should if they put bad tires on a car.

Beeeeecause I've looked at a couple threads like this, and started at LEAST one of my own. I can't find ANYONE on here who will post a pic of what it actually looks like! It's kinda hard to remove it if I don't know where it is...

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.
These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.
Look up "cold start assist".

a service bulletin tells the shop HOW to repair a certain symptom on a certain car. it is not an extension of warranty
