Volvo L-4 Installation Guidelines
Install the grill from the inside of the duct with the
vanes pointing upward. Use two cable ties to secure
the vanes so they will not turn.
Drill holes in the duct transition, and pop rivet into
place using the supplied rivets and brass washers
Push the duct and grill back into the hole in the
Volvo duct. Attach the 4" duct with a hose clamp.
Push the duct over the grill until it is tight against the
transition, and then tighten the clamp (Fig. 16).
