Just brought my new-to-me 2002 SE home, and noticed this while under the hood. It appears there is a vacuum line disconnected, but I cannot see anything that it is supposed to connect to. Does anyone recognize this and where does it go?.....Thanks in advance for any help.

P.S. yeah I know the engine bay is filthy.......I'm working on that...

 

It's a breather ...

 

So it does not need to be connected to anything right?.....

 

Nope, I have 2 of them on in my 95 and 03.

 

it leads to the transmission....its open at all times to let the transmission breathe....yup yup

 

Thanks everyone......I'll have a few more questions later today after I search the Stickies some more.......

 

I wish more people were like you....

 

I wish i was

 

Congrats on the purchase....

 

my favorite newbie of all time!!

 

but it's another freaking jason....

 

well jasons are always smarter

 

Oh great...

 

Why does the tranny need to breathe?

 

Because it is a living breathing thing....jk

It needs air to keep cool under hard acceleration and heavy loads....(going up hills)

 

As the tranny gets hot, the air inside expands and needs to go somewhere. If the tranny housing was completely sealed, the heated air, along with tranny oil, would probably be forced out the seals, causing them to leak. Then as it cools, the air would get dense, creating a vacuum and possibly pull dirt back in around the seals and bearings.

 

preach on brutha!
