i have an 82 base model and on the passenger side fire wall there's a bottle that says sub-zero use 90% water and 10% antifreeze with a line running to the carb. i was just wondering if anyone on here knows what it's for????

 

its for cold weather, it runs to the engine to help heat it faster ... i think thats what it was for, i ripped it off my car

 

me too

 

The same bottle is on 2nd gens. They have a Tech Service Bulliten that says to remove it.

Most of the time it's non functional.

It was used to inject a high concentration of Antifreeze into the carb to prevent it from freezing up and from ice collecting on the intake and in the engine on startup in literally sub zero weather... If it doesn't get below zero where you live, you shouldn't need it.

 

Mine hasn't had anything in it since 1984... I'm assuming its really not critical!

 

it doesn't affect anything at all beside maybe the ease to start the car up a little during winter time ... but whats wrong with the water freezing in there? i thought colder air means more power

 

your air-fuel mixture thats entering the chambers looks like a slurpee. lol.

 

i have a 85 12a will i have one? lol never seen what your talking about if i do im going to take it off oregon gets cold but not that cold and why keep something that takes spaceif you dont need it just likethe rats nest!

 

It's the bottle in the very bottom left of this picture...the one that looks like it has 2 caps.

Yeah I got rid of mine on my '83, and my '84's was gone when I bought it.

 

I turned mine into a bong
and yes it is still in my car

 

^you gotta teach me how to do that

 

It involves one long tube, one drill, one unhealthy disrespect for the law, four twinkies (three won't work), roughly thirteen hours of Stripes (Murray at his best) preferably on a black and white 11 inch TV, and about 35 hours of "what did I cut?". Repeat as nec.

 

One small correction. 90% antifreeze, 10% water. They are one of the 1st items to come off of my rotarys.

 

Yep, you will (unless someone ditched it already).

 

My 85 S doesn't have one, the lid doesn't even have the nipple for it just smooth

 

The nipple pictured on "64mgb"'s vehicle is not for the sub zero system.

Notice how his car is also missing a charcoal canister (About the size of a coffee can, all black, has two or three tubes on top, located near the right strut tower.) On 1979 and 1980 cars, and perhaps Series 2 as well, the charcoal canister was integrated with the air cleaner lid.

 

Sorry for posting over a month later but I live in Canada, and most winters get pretty cold.. are you all saying, even with this bottle and antifreeze hooked up it does absolutely nothing to help the engine start? Why would Mazda put it in?

 

I live in Buffalo NY , it stays

 

I live in Cedar Rapids, Iowa...mine stays...and works.

mazda put them there to help the apex seals...kinda like a motor defroster.. the sub-0 will imporve motor life.. and should be used any where the temp gets to 32deg or less..... that being said i jurked mine off a long long time ago...

cheers PaTricK

 

If it works for you cold weather guys good. Cali did not have them due to emissions and Mazda did issue a TSB to remove all of them, though I'm not sure why.
