Evaporative System Components

Are you getting P0442 Small Evap Leak, Well then 90% chance that this hose is causing it. This is also called a J hose because of the design. It fails because the rubber cracks where it fits over the connection on the Charcoal canister ( Left side of canister connection. To replace it you have to drop the exhaust pipe, take the left rear tire off and remove /drill a rivet that holds the aluminum heat deflector ( 2 rivets there) and 2 speed nuts. Once you have that removed then you have to disconnect the front connector on the canister, if you have a set of picks that helps. I tried to get the canister off the rear axle but didn't have success. Also I dremel with a cut of wheel to cut the old clamps off. Be careful when you cut the clamps off that you don't go to deep. If you do then you ruin the canister. It is a fun job on your back in the driveway. This job at Volvo would cost almost $300- $400 between diagnoses, smoke test and at least 2 hours of labor. After you finished and put everything back, the light will go off after 4 or 5 trips. Good luck.
