XC70 Vacuum leak/ smoke test

Post by sjk5539 » Mon Oct 08, 2018 10:34 am

Hello,

My 2008 xc70 got a p0442 (small EVAP leak) code and I am trying to smoke test to see where the leak is.
However, I can't figure out which hoses are vacuum lines and where the purge solenoid is.
I think I can use this line (picture attached) that is connected to the coolant reservoir...

Does anyone know where to introduce smoke?

Cheers

The line you identified is full of coolant

The line that you are looking for is shown below
