Thermostatic warm air intake

[Obormot]

it's from old VAZ car (USSR)
VAZ 2108, 2109, 21099 models, engines 1.1, 1.3, 1.5 l.
also it was on early models of 2110 and 2111 cars with same carb. engines.

price in Russia about $15
in Ukraine price almost the same, but now i move from Ukraine to Russia becouse of war.

found video, that shows how this thermostate working.

on video operator warm-up thermal element by hand, and door slowly moving from "cold intake" position to "warm intake" position.

veeeeery slowly, becouse temperature of hand (36.6C) just slightly higher than "switching" temperature of thermaostate (about 35C).
if temperature will be higher (for exapmle, put element to hot water) door will switch much faster.
and if element put to cold it will move door back to "warm intake" position.

I got mine today from Ukraine.
And you answered my next question. 35'C is just about perfect.

Is there a larger version of this part for a slightly larger engine?

I just bought one.
Total impulse buy, I will figure out what to do with it later.

What website?

ebay.
I punched in that part number a few weeks ago, bought it and it showed up this weekend.
If the seller could go to Russian NдPд and buy one of these thermostatic controllers for $15 and sell it on ebay for $43 (plus shipping), if I where them I would keep trying to sell them.
I have a but load of money tied up in paypal so I was not worried about getting it $5 or $10 cheaper some where else that does not take paypal.

Edit: I just checked ebay and there are 2 on there now, a little cheaper than what I bought mine for.
Just search "2108-1143010" only 1 item will come up.

I say buy the one from the guy in Ukraine, do your part, help them rebuild their wrecked country.

no, only one model.

now i thinking about producing of part like this in 3-4 sizes for bigger engines.

This is '70s tech, it made it easier to jet a carb when the intake air was always one set temp. Now we have OBD2-level SMPEFI, this hot air tech is obsolete. The cheapest and easiest solution is to embrace the horror of the newest engine in your local salvage yard. Swaps are fun.

For some of us, custom fabricating a plethora of components to swap an engine would be considered more expensive and difficult than attaching this out of date WAI... If it works, who cares when tech was developed?

Maybe for you.

We don't all have garages, we don't all have engine hoists, we don't all have years of mechanical experience. For some of us, making little changes here and there is the limit of our competence, "dipping our toes in," so to speak. It would be better to encourage and constructively advise those people, rather than tell them to drop their idea because it's old or obsolete.



Also old and obsolete. But it works.

I've done probably 20 engine swaps. I admit it can be fun. I also don't see much reason to swap a perfectly good engine out of a daily driver, for something from a junk yard that may have unforseen issues.

To date I have swapped two engines: one from a 1971 Opel GT (actually that was pulling the engine so we could send it out for machine work. Rebore, line bore, new bearings, the works) and one from a 1983 Snapper mower.

To pull the Opel's engine we had to build an A-frame to support the winch hanging from the garage beam. That was two houses ago and my dad was the point man for that project. I like to think I know something, but most of what I know is facts, not practice. I'm just muddling along, trying not to screw up too much.
