smog pump

[thankins93]

would it be smart or not smart to just take the belt off my smog pump? i really dont know to much about these smog pumps, the truck is still fairly new to me

You can.... Or eliminate the whole thing like I did. It doesn't affect the way the truck runs, but you have to swap manifolds

and what are the pros and cons of "de-smoging" the motor?

Clean up the engine compartment. Less parts to break. Easier access to other items, (plugs, wires, etc.)

I just disconnected my smog pumps (2), and due to a manifold leak, ended up hacking off the spider web of AIR tubing, and replacing with headers. Headers were cheaper than replacing the exhaust manifolds (other than going to a junkyard.)

I was able to eliminate a bunch of vacuum lines, and replaced the rest that were rotted off.

Basically this, as well as that little bit of engine drag will be gone. Also, smog pumps [mainly GM ones] tend to just randomly seize up over time. PA emissions/inspection is pretty strict if you go to the wrong place and if they don't see any evidence of a smogger being there, they don't question it.


Basically the best thing to do is eliminate and forget.

If I didn't live in California, My smog pump would have been in a landfill a long time ago. It wasn't just the GM ones that seized up...pretty much any 70s car i've ever had, the smog pump seized up on it.

what all would i have to take off to de-smog it correctly?
