First off, let me say this thing is a total PITA to remove and I'm hoping I don't have to reinstall it. Can someone tell me what this is and what it does?








Thanks in advance!

 

Cold start assist bottle.
Rip it off..it's a piece that Mazda should have never used in the first place.
You can just disconnect it and then cap off where the hose goes at the engine.

NOW..I noticed you took it off THEN wondered what it is.

TIP: before you take anything else off the car,find out IF it is necessary and what it actually does.
Otherwise you will just be another member of the "why doesn't my car run right" club.

 

Whew glad it's not important. It would be such a struggle to get back on.

I normally do follow that rule of thumb but in this case I'm pulling the na motor and swapping in a turbo ll motor. In a sense I still am going by those guidelines just doing it a little out of order. I'm still finding out what things do and what's necessary before I drop in the t2 motor and try starting it.

Thanks for your knowledge and tip 😊🖒

 

Mazda issued a TSB for dealers to remove it.

 

TSB: that stupid bottle.

 

Makes a nice little methanol injection bottle though...

 

Probably work as a water spray on the radiator, air or oil cooler, too.

 

I've used them for all kinds of strange tasks. Coolant pump on my band saw, emergency washer fluid replacement bottle on my old beater 1st gen, Windex dispenser when I had a LOT of equipment to clean...

 

Every year, from 1980 to 1990.

Every. Year.

Meanwhile, every RX-7 I have owned still had that bottle, except for the current one that some moron did a engine bay "OMG GET RID OF TEH RATS NEST LOL" which is part of how I got it so cheap. Making it pass emissions was fun, for me, because I got to experiment with what minimum equipment was required to pass a roller test. And I have had 100% stock cars fail the roller test because the test is poorly engineered.

 

My FC failed years ago when the only mods were a catback, Bonez cat and cone filter because they tested it in cold start (there was no cold start test in Ontario). Failed 16xx on hydrocarbons. Next test, I showed up at exactly the time it was to start, they drove it right onto the dyno and it passed with hardly any HC.

 

Haha yeah I don't think my car has been serviced by mazda since it left the dealership 30 years ago. But cool so glad I don't have to put that bottle back on. I'll hold on to it in case I find some weird use for it.

PS I don't have to get emission tested where I live 😝
