What the hell is a Thermostatic Air Cleaner...

[Californiafeind]

...and why can I pass smog with out it? I just went to the smog place today and I failed. I failed because the upper intake has been "tampered" with. Now tampered = kkm filter, Lincoln mark 8 mas, silicon intake tube, and a bbk throttle body. I passed last year with the same set up, in fact the guy who tested my truck really liked the set up. The truck passed everything else. Well the dude today wants me to put all the stock stuff back on so he could test it again. WHY? It already passed smog, does he want it to be better than just "passing". Further I never took off a Thermostatic Air Cleaner. I took off the air filter box, but from what I can figure that was, well a box. Could someone indicate what a Thermostatic Air Cleaner is and where is might be located or tell me this guy was mistaken. It's a bizillion degrees outside and I don't want to bring the truck back to stock, and if push comes to shove does someone have an air box they could donate. I just need it to pass smog and if you want I would give it back. Thanks.

found this 1/2 that way down idk if it helps at all

Thermostatic Air Cleaner
The Thermostatic Air Cleaner System is an early emissions control device that was designed to deliver temperature-regulated air to the intake manifold such as warm air for cold engine conditions and cool air for engines at normal operating condition. Thermostatic Air Cleaner systems usually consist of an enclosed air filter housing, with an air intake snorkel containing a thermostatic control valve. This thermostatic control valve controls whether cool air or warmed air enters the intake manifold through a vacuum signal. Later models have used electrically activated thermostatic control valves. After the engine has reached normal operating temperature, the thermostatic air control valve returns to a position to allow cool air to enter the intake manifold for normal engine operation.

Hello!

Sounds like your definitely in a bind. I didn't even think of the fact that putting an "after market" air filter would fail my truck.. here in NY mine past fine.

If no one comes up with a better solution i have my stock air box that you can have ( just wasting space at this point here in my apparetment, haha )

I'll keep checking if anyone doesn't post a better idea, then it's all yours. PM me your address and i'll send it on out.

that's bs man if it passed the sniffer who gives a damn about what hardware is installed!

Frikin econuts thats who!

I was readin the other day and read a quote that I think was takin from nancy pilose(that could be wrong) she was talking about future legislation to "bring about an end to the automaker's horsepower war and shift to a war towards better economy."


Most disgusting words I've ever heard. A government official trying to order a private company what to do with its product direction.

That's socialism folks!

Californiafeind, your 92 Explorer doesn't have one of those beasties. My old Chevy did have one, it was an aluminum flex-tube, about 2 1/2 - 3" in diameter, about 12" long than funneled warmed or heated air from the exhaust manifold to the air intake. There was a vacuum line that opened or closed a butterfly valve in the air cleaner intake tube that would block or allow heated air to flow into the air-filter housing. In cold weather, this preheated air from the exhaust manifold would feed into the carb so that the engine would warm up a little faster. They were only used on cars with automatic chokes as far as I know. Not ever used on an electronic fuel injected vehicle. Someone correct me if I'm wrong though.

...What you just described is what needs to be disconnected to install an aftermarket cone filter,(Minus the heat tube of course)...The butterfly is just behind the pass headlight and the vacuum line runs from that to the stock air box......

 

[CDW6212R]

That stuff was pre-Explorer, these have idle air bypass(IAC) solenoids to correct idle issues as when cold. Likely they do mean the air cleaner, which receives the same air whether the engine is hot or cold. Good luck,

 

[Tbars4]

...There is a thermostatic intake air control on the 91-92 ford explorer with a vacuum line on it going to your stock air filter box...

 

[Californiafeind]

Those dinky little lines?

Are we talking about those little vacuum lines that came off the stock air box?

 

[Tbars4]

...Yes...One goes to the thermostatic intake air control and the other goes to the motor...Do you have an aftermarket air filter and are those vacuum lines disconnected??

 

[Californiafeind]

The lines are off. I have a cone filter.

**NEWS FLASH****

If you live in the Communist State of California, and you want your vehicle to pass a Smog Inspection, It must be bone stock, just the way it was born! Any changes will cause you to flunk your smog test. (even if the emissions are better)

Does your new configeration have a C.A.R.B. #???? If it does you pass go, if not see above!

 

[CDW6212R]

Agreed, that's the way the dumb rules are written for California. I'd swap the stock air cleaner on for the test each time.

 

[Blacksheep Josh]

that's why i love living where i do. no emissions, no smog, no nothing. as long as your tail lights and headlihgts and horn works, we're in business.

 

[zonianbrat]

Guess I'm not moving to California! Are there any other smog places you could go that might be cooler? I mean does every single person in Cali that has aftermarket intake have to put on the stock one to pass smog? If so that sucks! We used to have to do emmisions in Ft. Collins but this past year they did away with it. Denver on the other hand still makes you do it but they never say anything about the intake unless it fails smog

 

[Tbars4]

...Here is a pic of my setup...The KKM filter pretty much sits just above the bottom half of the stock airbox...It takes a whole 10 minutes for the swap to stock for the smog test..

 

[HahnsB2]

Bring your stock setup with you next time and shove it up that guys ass! It passed, plain and goddamn simple. They don't even lift your hood here, just pull in, plug in the wire to the cig lighter, exhaust probes, run test, pass, leave.

 

[Flip4ford]

No inspections here at all... as long as you have cash, you get your registration renewed

 

[briwayjones]

I thought the KKMs and other open air filters are certified 50 state legal? If they are than I would think whether they want to see stock or not and be jerks about it by the law you are legal and there is nothing they can do about it?

 

[Tbars4]

...As mentioned, they are not C.A.R.B. certified...This is from KKM...

Is the True-Rev Induction kit emissions legal in my area?

The True-Rev Induction Kit is designed for competition use and though it does not eliminate any required emissions devices, it does not carry any emissions exemption certificates. The bottom line is check with your state testing stations for guidelines on engine modifications. Our Kits are not C.A.R.B. certified.

...And here is a link for C.A.R.B...
