Routing the pressure hose
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.
NOTE:
Ensure that the hose follows the rubber trim on the plenum chamber. Ensure that it is then routed out of the engine compartment at the rear corner of the bonnet. The adapter hose joint at the T-valve must be outside the engine compartment. This is to ensure that neither the bonnet or the hose are damaged when the bonnet is closed.
