I'd really like to get rid of the smog pump on my car but there's no way I could get an emissions sticker without one. Is there anything wrong with removing the smog pump's belt, while still leaving the pump attached to the motor? When I need to get the car inspected, I could take 5 minutes and put the belt back on. Any thoughts?

 

you can do this, but don't be suprised if the pump is siezed when you go to put the belt back on. I did this last year and when i went through inspection i had to borrow someone elses pump, cause mine had siezed up...

Why does the pump seize up... just because it's sitting there for a while without moving?

 

i don't know why it does, something to do with the exhuast still going into it or something, but really, your not gonna notice much of a difference with it off anyway, maybe 2 hp...

Without the pump running, exhaust will get back into the pump and seize it up. There are supposed to be check valves in the system, but they aren't perfect.

You will not be able to tell any difference between power with and without the pump. I kept 1/4 time records a couple of years ago; except for the notation indicating which have and which don't have the pump running, you can't tell the difference between the runs.

 

The only reason to eliminate the pump is to get all that crap out of the engine compartment. Just pulling the belt accomplishes nothing worthwhile.

 

If you think a seized pump is bad, wait until the exhaust melts everything and you have a huge leak in the engine compartment. That really sucks.

 

Well, i fixed that problem by capping the air tubes on the headers.
