Remove it cuz its a dead weight of 7-10lbs. Not necessary period. Remove it, put the little sticker on the front radiator support, Remove the fuse/relay. 3step process

No, IIRC, the air pump kicks on for all of 30 seconds on start up. Most air pumps on the cars are shot anyway.

Just take it off and be done with it.

You do not need to remove it. Removing the relay just makes it stop working. We have procedures from the factory we follow regarding the AIR pump, we connect to the car with our computer,use our GM software to update the car computer and eliminate the program from the computer then attach a required decal stating we did a federal emissions update to delete the AIR pump device.


Removing the air pump,bracket,tubing,check valves,hoses and capping off the manifolds are all things done for cosmetics and slight weight reduction of unused and unneeded parts.

It's also done so you don't have to remove the damn thing every time you want work on your car. Seems like step 1 of just about everything is "remove air pump."

It is legal to DISABLE the air pump per the TSB. It is technically not legal to remove all the disabled hardware. It is a fine point but you may fail an emissions visual check in some areas if the hardware is removed. (This is not a problem in Ohio.)

You can get an official looking sticker from an online vendor that says all the hardware removed was disabled per the TSB. That has allowed some owners to slip through those checks. (Legally it means nothing, but some inspectors have accepted it in the past.) Otherwise, you will have to reinstall all the hardware.
