86 13b engine compartment
I recently had my oil cooler line blow a leak on the freeway. Saturday while working on it i noticed a little water bottle in the back left side of the engine compartment. It has a pump at the bottom of it and a little rubber hose that makes itts way to the intake manifold. I was wondering if anyone knows what it is? I am kinda wondering if it is by some chance water injection. I really doubt it being a n/a, but any feedback would be appreciated.

Depends on what you mean by left, but I'm assuming passenger side. If so that's the Accelerated Warmup System that holds coolant/water. Info about that is in the Sticky.

re:
im not sure it would work if it had water in it. The little motor is borderline rusted out and it looks to have been dry for quite some time. There isnt anyother way to get water in to it except manually.

That bottle has noting to do with the your car reving to 3k. What does that that is the AVS and the thermowax stuff in the TB that cause the higher RPM startup.

Personally, I don't think it's capable of doing much damage, maybe right up there with piston engine cylinder wear caused by starting with no oil film on the walls...And with premix, you don't even have to worry about that

I said the AVS and the thermowax control the high start RPM's, not the cold start assist bottle.

Just make sure you plug the holes in the intake when you remove the valve. I just used black RTV for this, and it's still there over 2 years later...
Hermit- lower than 60 (or so). Every now & then we actually get below freezing
I guess it's just the ECU (fuel scheduling) and the BAC (to open the intake passages) that kicks the 3K warmup on, because it sure as heck ain't the air bypass valve...

well i just removed the reservoir, however there is still a grey/black cylinder thing above it, it has an electric plug that connected to the reservoir, and also has a long black hose connecting to a nipple below the water thermo thing. also a cable is attached to the cylinder and hooks up in between the firewall and TB... i can cap the black hose, it is sucking something from the grey cylinder, but what do i do with the cable that's connected to the spring loaded thingy?
as for the electric plug im letting it hang there wrapped in tape... and no this is not the charcoal canister im talking about, its right behind it, near the backside of the wheelwell, next to the firewall, right above the cold startup reservoir.

hmm upon closer inspection, it doesnt even have anything to do with the cold start assist... its just a hlaf black half grey cylinder, bout half the height of the charcoal canister. has one thin rubber hose going to a nipple on the intake mani, in between the firewall and TB, under the water thermo nipples. and it has a cable, looks just like the throttle cable, that hooks up behind the TB also. car runs a tad rough with the black hose off, putting a finger over the nipple returns it back to normal. as for the cable, it just sits there, does not move when engine is reved up either. it IS on the same assembly as the front throttle cable. so... anyone know what this is for and if it can be removed? car runs ok with the plug disconnected, nipple plugged, but havent touched the cable yet.

What you just described is the cold start assist bottle, and where it connects to the intake manifold. If you remove it you will need to block that nipple off as mentioned earlier, or do what I did and make a block off plate.

it cant be the cold start assist bottle, i already took that out! i'm talking about a half grey half black color cylinder with a cable attached to it going to the butterflies on the TB, also attached to it is a electric plug, and a black rubber hose that goes up and connects to a nipple around the TB also. when that hose is taken off the car doesnt run too well. however i looked in the haynes and my only conclusion is that its the cruise control, why else would a metal cable be coming out of it and connecting to the TB butterflies but on the other side?

Ok, ok. I see what you are talking about. That is the AVS control., so yes it does control air goign to the Dynamic Chamber to increase RPM at startup. I am not shure when we moved from the cold start assist to the AVS.
