Excellent video, I can add one trick to save you from removing the muffler bracket and the 3 bolts. Slide a 1/4 drive extension in between the 2 spokes of the muffler bracket and then place your 10mm socket on the nut, connect the two tools and remove your nut. A 1/4 drive fits perfectly between the 2 spokes of the muffler bracket a 3/8 drive extension will be too thick.

Great tip! Honestly I'm not sure why a 1/4" drive never crossed my mind. If I ever half to tackle the EVAP canister again I'll make sure to try that!

Appreciate you, and bummer about all the rust. East coast? I'm in Colorado they don't use salt, just wondering. I feel like I stole this one. 3 mechanic shops couldn't figure out why a different mechanic screwed something, but a year of trying to figure it out with misfires allowing it to pump raw fuel out the exhaust, thus melting down the cats. 119k mile on a '08, great body, new tires. I just bought it $700. Gutted the old melted cat to let exhaust out and reinstalled, bought Amazon coils and plug for $80. still had weird misfire, then looked for coils that could have room to have to have accidentally been crossed. Sure enough, cyl. 1 & 3 had enough length that if not careful, they could be mixed up. Swapped the coil pug connectors, fired it up and misfire gone. Found cats 2 each side connected as one 1 unit each side, dirt cheep like $120 for all, easy swap. My girlfriend just scored bigtime. My health is shot from 45 years of fixing cars. can't breathe enough to walk 5 feet. 64 years at over 100 mph, going out just like when I came into this world screaming, but this time yelling "wow, what a ride."

Thank you! These are great vehicles, but are prone to rust especially when expedited by salt on the road, but these drivetrain are bulletproof with regular maintenance. I hope you guys enjoy your EX35 and also for better health for you also.

I’m trying to figure out what hose connects to that control valve. I recently got a car from auction with that missing valve and hose.

[@AwkhuardVQ]

The part number for the hose is 18791-CD010. Follow the other EVAP lines and until it brings you above the subframe and there's a little black spout sticking out of the body. That's where it'll plug into.

JUST GOT THE CODE AND NOW I KNOW WHAT TO DO, DO YOU NEED TO GET OEM PART FOR IT OR AFTER MARKET SHOULD SUFFICE?

[@AwkhuardVQ]

I always recommend getting an OEM over aftermarket even if its used. This part shares with most Nissans and INFINITIs before 2010. If there is a local picknpull or salvage yard near you can I'd say check there first, if not, then online is your best case. You could get an aftermarket one, but YMMV on those.
