WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Fit the lower pipe using a new O-ring.
Fit the upper pipe (return line) with mounting in the control system cover.
Fit the connection loosely. The bearing cap of the pipe will be tightened later.
Assemble the clamp and tighten the screw.
