Can anyone tell me the pros and cons of bypassing the Air pump. It's making awful noises and my mechanic said there wouldn't be any problems since my thermactor system was eliminated long time ago.
I've already bought the correct belt at the right length. Will the computer know of this? Any side effects? (emissions isn't a problem where I live just in case it has anything to do with it)

 

the computer will detect the TAB & TAD solenoinds as not working properly.
I'm sure a search will yeild more info.
How did you make out with the cooling problem?
Happy New Year

And Will it give me a check engine light? (remember mine is a 6 inline 300)
No other side effects you could think of?
My cooling problem was a clogged radiator. I will install a thermostat tomorrow also. Will replace my fan clutch next week too.

 

oops - yes I beleive codes 81 & 82 set the check engine light.
No other (negative) effects that I can thing of as long as you are sure to plug everything up.

 

I think that depends on the year.

My 93 F350 hasn't had an airpump in a very long time, and I've never had the check engine light indicate the air pump is missing.

When I download codes occasionally, I've never had one flag the air pump, EGR, or any of the other emissions stuff.

Maybe I'm just lucky

 

naw, You're too smart to have luck.
You probably built your own bypass curcuits out of parts from a old pong console...LOL

Happy New Year Frederic!

As long as you keep the solenoids hooked up the computer won't know the difference.

 

I removed my air pump on my '94 f150 w/302 and haven't had any problems. The check engine light came on once and then i turned the truck off and restarted it and it went away. So I don't think its affecting anything.

 

Happy New Year to you also!

No, the air pump fell off years ago (the bracket is still there, loose and rattling... been meaning to remove that for a few years now... LOL).

While everything is capped and plugged, the solenoids/valves are still there. I got rid of most of that functionality because I was tired of vacuum leaks.

 

So which are these solenoids and what do I do with the hose that plugs to the air pump from above? the one that comes from the thing on top of the alternator, quite some hoses plug to this thing and a vacumm line too.

 

Happy new year everyone! I wish you all the best!

Can anyone tell me what a smog pump does? what's its job? I already bypassed it and have gotten no check engine light whatsoever.

 

The smog pump (air pump) pumps fresh air through a tube into the catalytic converter, to help burn "stuff" that would normally pollute the environment.

If you remove the pump, plug the hose, and enjoy life.

 

It must be nice to live in your part of the country that doesnt have emissions I/M240 tests and visual under hood examinations! In my part of the country--your truck would fail if it didnt have an air pump if equipped with one from the factory. And without the air pump--we couldnt enjoy life!! The "Clear Air Staffel" wouldnt let us.

 

I live in NJ, and we have dyno-based emissions testing here. Fairly stringent testing too.

But, if you pass, they don't open the hood.
If you fail, they do. Well, they're supposed to.

I have my crewcab over-registered in weight, so for an extra $7 a year in registration costs I have the truck as a 10,500lb pickup, which in NJ means I only have to pass an idle test, which is extremely easy.

And to be honest, the air pump system even though it's OEM isn't necessary anymore. The new aftermarket cats are very efficient, much better by themselves than the crap in 1993 when my crewcab was made, WITH the air pump going. So based on the emissions testing I've done, I pollute noticably less across the board without the airpump, and a nice shiny new cat converter.

But as long as there isn't a visual inspection, I can get almost anything through emissions here with proper tuning. My FWD, 1993 550 horse Continental breeze right through. Though the first time the local DMV testing facility romped the throttle he flew off the rollers.

 

THIS A TRUE STATEMENT; As well plug the vacuum actuation lines from the Solenoids, A print of the vacuum lines is under the hood some where, on My 250 its on the air filter box, on the Bronco its on the hood, refer to it to make sure you are getting the right/all lines.

Good luck
