Hello all, since I am new here I wanted to post some questions. I have just bought a 1990 Ford Bronco and the Smog Pump is disconnected and squels like a champ. Is this pump necessary? Should I replace it or just remove the pump and get a smaller serpentine belt. This is my first in a long line of questions with this new project. Thanks for everyones help!

Ok if you have emisions to pass then you will need to replace or reattch the pump the only thing its used for is to cool your cats down to help keep you from burning them out.. If you don't have emisions then you can take it off and the cats also.. :goodfinge

They brought in emissions checks here

30 years after most American states and in view of the fact many states are ditching their checks (A-holes !).

This left me scrambling to find a new pump. Happily Cardone sells them remanufactured for only $45.00 American (keep your pulley).

Strangely, since my bronco turned 20 and is now emissions exempt, the pump seems to be missing from the truck again ????

I'd offer you my old one (if I knew where it went:toothless ) but I'm told they seize faster than a new 4.8 Chev engine dies after the warantee runs out.

Ok, I didn't mean to start an argument or anything I am just wondering what to do because 1) The pump hoses are not hooked up and 2) It is sqeuling like a champ. I just wnt to know if it is easier to replace the pump and rehook the hoses or take the pump off entirely and get a new serpentine belt that will make up for the removing the smog pump. Thanks in advance once again. I am looking for a tailgate that has no rust on it or the rust in not all the way through but i live in Michigan.

Sorry six but thats what i was told the reason for the pump was to keep them cool but i gess my uncle is wrong he only has been working on cars for 30 years..:drinkbud
tweren't me that replied to you Graydevil

That was Steve83 (he's been teste these days, all bored sittin' at home so don't take it personally, he's just setting things straight {and he'd know}).

I'm not sure how they all work together either. My pure joy (for losing my pump) was because I can now access the passenger side plugs so much mo' easily

Geezely Graydevil

I just re-read the first line in my response and realized it may not have reflected what I was saying.

I was calling my province the A-holes for instituting an emissions program, at all, 30 years late to the party(firmly bolting the gate after the horse escaped, lived a long life and died and was made into glue).

Most American states put some kinda enforcement in place shortly after the first catalytic converter attached itself to a Chevrolet in 1975.

My Province didn't in the 70s, didn't in the 80s, didn't in the 90s. The A-holes waited until 2002 to start a program that most states were ditching (because it was inneffective and just penalized personal vehicle owners needlessly).

I wouldn't blame you for pitching your air pump if'n you don't need one, but Steve is entirely correct in saying an EFI 5.0 litre, with everything working properly, will really deliver the goods mileage and performance-wise.

Too many of us with a dead or dying EVR or EGR, or rotted out AIR pipe start blaming the cat and pump on our troubles, when that just isn't the case.

If you're going to do nothing to the catalytic converters (leave them on there), then you need to replace it. End of story.

This has nothing to do with mileage in the short-term, but may eventually cause converter failure if you remove it.
