on the passenger side of the engine bay, againt the firewall there is a small tank (white) in my 88 s4 n/a and i was wondering what i should put in it. there is a pump on it and a hose witch runs into the intake manifold; gas or what goes into this tank? https://www.nopistons.com/forums/pub...IR#>/blink.png

this is a cold start assist resovoir. it would normally have anti-freeze in it and on cold day it would inject anti-freeze into the intake manifold. Mazda had a TSB on this and discontinued it. you should disconnect it and remove it. also if you want you can remove the injector. Banzaitoyota sells a block off plate for it
|
oh thats what it is thank you.

im not positive but i think 88 was the last year they used this. i removed mine from my 88. i dont see what the point is of injecting anti-freeze into the intake is. how in the hell does that help with cold-starts? one would think injecting a non-flamable liquid into the engine would impede starting.

Well, it was something that Mazda used for quite a while, since my '73 RX-2 had it also. |
It also helps to unstick your seals
|
so is it worth keeping?

You live in Texas? Does it EVER snow? Even so, they removed the system for a reason, I am sure. If it was honestly so great I would think it would be used today on even the RX-8, but it's not to my knowledge. I have mine still on the car, but I leave the tank empty. I dont' see much of a point in removing it. It probably weighs..what..a pound?

Can this be true? I may wish to acquire one of these. Just trace the flange from the cold assist injector onto a peice of aluminum and buy a hack saw blade from home depot for 4 bucks. Drill two holes and that's it, some RTV and done. Why do people need to buy block off plates? They are the simpliest thing to make. |

It all boils down to the old TIME vs. MONEY and which one do I have more of? https://www.nopistons.com/forums/pub...1047683785.gif |
Banzaitoyota's block off plates are very inexpensive(the cold start plate is 8 dollars) and they are made from 1/8 inch water-jet cut stainless steel and come with hardware. i would rather spend 8 bucks for a nice plate than 4 bucks and 1 hour of my time for a ugly aluminum half-assed plate
