Need vacuum diagram/help for 2001

Need vacuum diagram/help for 2001

Postby jal [OP] » May 29th 2010, 3:11am

I am replacing some of the vacuum lines on my 2001 Astro since one was broken. While removing that one, another one broke, and I discovered a third one which was not attached anywhere. I don't know where this mystery hose should be connected. I looked around and could not find a diagram under the hood. I have a Haynes manual and it does not show a diagram.

I'll try to describe the mystery hose. First of all, there's a line that starts at the left valve cover, and is about 2' long and ends up at a T connection with a check valve in it. This connection is on the passenger side of the engine compartment and can easily be seen/reached from the front/top. The check valve is between this 2' hose and two other hoses, one short, and one long. The long hose was not connected to anything.

Thanks for the help.

Are all hoses connected to the vacuum ball? It's about in the area you describe. Jim

Yes, nice! Once I got the cowl off I could see the "ball" thingy, so I plugged it in there. Thanks for the help!
