| I would like to install ac in my truck. But to do so I must remove the
smog pump do I need the smog pump to pass smog? And what doe's the

The smog pump (air pump) injects fresh air into the exhaust stream so there
is a combustable mixture that enters the CAT, which heats up and burns the
remaining fuel so that result is cleaner exhaust.
The exhaust stream contains unburnt fuel. The CAT burns this fuel through a
combustion process, but combustion requires three things, air, fuel, and
heat. The fuel is the remaining unburnt gas. The heat is the CAT itself. The
air is injected by the smog pump.
So, yes, the smog pump is required.
As I recall, you are in California. CA smog rules *require* all of the
factory emissions components, and if any of the ocmponents is missing, you
automatically fail the smog insepection. It is entirely possible to have a
vehicle that is modified and emits clean air, but if the smog equipment is
missing, the car will fail. In order to remove smog equipment, you have to
replace the system with a CARB (Calif. Air Resources Board) approved system.
We also talked the other day about your R12 air conditioning system. You
will not be able to install a new R12 system, or rebild the missing parts of
the R12 system you already have. You are forced to install an R134a system,
and this can turn out to be an expensive proposition. |

No combustion takes place in the catalytic converter. It is a
chemical reaction. It is an exothermic reaction which is why the cat
gets hotter - especially with an over rich mixture - but there's no
fire.
http://en.wikipedia.org/wiki/Catalytic_converter
Supposedly the air injected into the exhaust stream in the upper
exhaust manifold or exhaust port is to allow combustion to continue
into the manifolds. Since emissions tests measure the ratio of
pollutants to air rather than the total amount of pollution, I figure
all air injection really does is put clean air in the exhaust - which
makes it register cleaner on a sniffer test. >> Stay informed about: Smog pump / air pump |

Will it pass a sniffer test with the pump removed? If the engine is
in good condition and the catalytic converter is nice and hot,
probably.
Will it be legal? Technically, no. Depends on your state whether you
can get away with it. In my area, there's no sniffer tests but
functioning emission control equipment is part of our yearly state
safety inspection. In a neighboring state, cars have to pass a
sniffer test but that's all. You'd probably be okay there.
In California, forget it.
But why? Wasn't a truck like yours made with both smog pump and AC
compressor? Go raid a junk yard and get the right parts.
You didn't mention the year or model - if it's OBD2 then who knows
what will happen. >> Stay informed about: Smog pump / air pump |

Does is not a contraction, you do not need the apostrophy.
Yes, $150 sounds reasonable for charging a system.
It does not really matter how much it costs to charge the system though, if
you take the smog pump off. Without the smog pump, you can not drive the
truck, and the AC won't help much when it is parked in the driveway. Allow
me to restatet that, you can drive the truck okay, but you can not get the
license tags renewed so that you can drive it on the street. >> Stay informed about: Smog pump / air pump |

I had to read the Wiki on that. In an ideal condition the NOx
reaction would release enough O2 to feed the CO reaction. But it's
not always idea conditions. Thus the air pipe. >> Stay informed about: Smog pump / air pump |

How about if I make it look like it never had the smog pump to start
with? And my truck is 25 years old this year. That means to what I
understand It doe's not need to be smoged anymore if the car is 25
years old or older.

It's different in every state. >> Stay informed about: Smog pump / air pump |

Can I just say I bought the truck from out of state if they ask where
is the smog pump? The truck doe's have new plates. If I did not hate
California's smog laws so munch I would not get so munch joy out of
fighting there smog laws LOL.

Hey!
If you really want the AC then have it smogged with the air pump and
immediately take out the pump and install the AC. Here in California
you would be good for two years till the next inspection.

Yea I was thinking that to.But It says on DMV that if a car is over 25
years or older it doe's not need to be smoged. But and then it says A
car made before 1976 doe's not need to be smoged. I do not know what
that means. DMV's web site It is telling me 2 thing that are 7 years a
part. Can someone please tell me why there is 2 different things they
are telling me.

If you're in California then you will need all the emission controls
installed and functioning. Get the right parts. >> Stay informed about: Smog pump / air pump |

I have an 86 PU with a 22R and it does not seem to have a Smog Pump. I've
seen some CATs with a fitting on the side, but rarely used.
