hello all! i recently picked up a nice 1995 940 wagon with only 249,000 miles. i'm giving it a tune up- changing fluids, pcv system, old lines, etc. Can anyone identify this valve that is attached to the intake manifold? it was broken and had a little oil in it when i got the car. also, is there a vacuum line diagram anywhere on the site? a few vacuum lines are disconnected and i don't really know what i'm doing with them. thank you!

okay, here are the vacuum lines i need help with:

^this one looks it was cut for some reason? it is attached to the wiring harness.

^this one labeled C. it hooked up to the intake manifold at the labeled nipple but was not attached to anything at the other end.

^this is a long plastic vacuum line that i think was originally purple and half turned green from heat. or maybe it's the other way round? it seems to be long enough to connect to the pulsair system but i wanted to be sure. I plan to delete/cap off the pulsair system anyway.

finally, this yellow plastic line terminates at the same apparatus the above line does. i found it disconnected with no indication of where it goes.

thanks in advance for everyone's help.

The vaccuum diagram in the 93 940 is in the engine bay pasted on the inner fender over the passenger side tire, near the coolant bottle.

Good luck, Bill

Hi *,

You should find a sticker under the hood with your vaccuum diagram.
It's wise to change out geriatric vaccuum lines to save a lot of random headaches.

Someone else can chime in on that valve.
How do you know it's broken?

Good luck, Bill

I don't see that sticker anywhere. is it under the hood insulation somewhere? Also I'm sure it's broken because it has a nipple for a vacuum line that isn't connected and the rubber it's made of seems to be torn up implying another half that came off somehow. From looking at parts diagrams i think it's part of the cruise control system?

Cruise control servo. I've never seen one cut open. It must have been like that for some time as it looks rather oily/grungy inside. The missing piece is a rubber cup with a cable attached to the end that goes around the throttle spindle. The other end is connected with a vacuum tube to the cruise control motor and an instant release valve in a brake pedal switch. You can live without it if you don't care about cruising.
