Re: Where does this vacuum line go?

Is that accumulator required? Or can you just plug the line?

S10DUDE is correct.

The vacum acumulator allows the cooling vents--vacum activated--to work properly by supply a reserve supply of vacuum when the engine has a "low" vacum state.

Older S10 vacuum reserves were like a "ball" and hung from the underside of the hood.


TO RE-ATTACH:
It's realy simple, the vacum accumulator is bolted to the drivers side (left) fender just behind the ABS--like S10DUDE said--and, it is bolted flush with the fender on the inside. SO, just feel around for the "nipple"
and push the vacum hose back on......

Mine is very exposed

The collision center just left it there after they repaired my fender.
Just thought I'd throw in a pic of what it looks like...

Re: Where does this vacuum line go?

If it didn't do something worthwhile why would they put it on there?

Mine became disconnected and my air controls wouldn't work, I was happy to just put it back!

Re: Where does this vacuum line go?

I bought my 99 s10 5 days ago and it has a few problems so while nosing around i found that where this pipe connects to the throttle body it had broken so i have replaced the whole pipe and the two from the T valve.

I now know the connector on the inner wing is for the vacum accumulator but what does the other pipe that goes in to cab with the wiring loom do?

Thanks, Dan.

It is the supply line for the Heating/cooling system inside of the cab.
