vacuum line on s70
 

where can i find i the vaccum line for a 98 volvo s70 n/a?
i was trying to seafoam the car, but i could not find where the vacuum line from the brake boost was.
anyone know?
thanks

Under the black cover ove the throttle body is a vacuum tree that you can connect a line to use for the seafoam.

which line do i use from vacuum tree and does anyone have a diagram of it so i can see which line to use?
And is it better to seafoam the car through the brake boost?
thanks,

There should be an empty port on the vacuum tree that you can connect a hose to and go.
