XC70 2001 Evap J hose RR

[vtl]

On second scroll through photos: canister really just magically slides out towards you? I find it hard to believe the rear access of that assembly is that easy.

With the rear subframe permanently lowered 5/8" (via spacers) I still was unable to disconnect rear hoses from the canister. My hand barely fit there and I can't sufficiently grab the connectors. So when the time comes, I'll be lowering the subframe to get to the canister. Heck, I'll drop it and replace all the bushings

Thanks. So all XC70s have this system? I should take a look under there. Is this a common problem? Is it a high mileage thing?

Yes; a general consensus is that the J hose life is 100,000 miles.

Would you mind adding a caption to each picture so that I can follow what you are doing? Thank you

Also add arrow to what I should focus on in each picture so I can follow. Thanks

A REBUTTAL To The Purported "CORRECT WAY..."

I had the same annoying problem, and yep - Volvo hides that evap canister and J-Hose in the WORST possible place on v70s, atop the rear axle, which COULD mean removing exhaust. But fear not, fellow Volvo caregiver - you are FAR SMARTER than to be so bold as to pull apart the exhaust, as you know that it will only end in tears, writing checks in large amounts, and so on.

Leave the exhaust alone! Yes, you'll need a lift, but loosen the bolts that hold that SUBFRAME (see photo below, outlined in red), drop it down a bit, and get the guy with the smallest hands (perhaps enlist a small child in the effort) to reach in and do the surgery to remove and replace the hose. Before he reaches in there, you need the two BIGGEST guys prying down with big fat pry-bars so you can slide in some nice fat scrap steel to keep the subframe jammed "open". Angle iron, inserted in the orientation of the letter "V" worked very well here. We used 4 pieces. "Safety First!"

(This is properly called "Laparoscopic surgery", as that's for gastrointestinal issues. "Arthroscopic surgery" is for joints, and an evap hose is clearly gastrointestinal".)

That's it! In and out in less than one hour total, The evap canister stayed where it was, and no exhaust components were harmed in the making of this film.

Can this hose be inspected fairly easily beforehand?

Can this hose be inspected fairly easily beforehand?

It is hard to see without one of those cameras on a cable that connect to phones and PCs you can buy from China for $15, but the TEST is actually easy - VIDA has a whole test sequence to check the EVAP system, and if the evap system is leaking, you'll have a check engine light and a "major leak in EVAP" code thrown.

You or a mechanic can also "smoke test" the evap system (lots of videos about this, and lots of homebrew smoke test machines to make), but I am not sure you will be able to see the smoke coming from the J-hose place where it typically fails (right at the evap canister) unless you first pull down the sub-frame as a I mention above or start removing exhaust components.

If it ain't leaking don't fix it, but if you are replacing exhaust components on a high-miles car (250K an up) I'd replace that J-Hose on general principals while it is easy and cheap to do so. Old rubber is not a good bet.

I’ve probably gone through three J hoses on my p80s but my one
P2 is still on the factory original from Ghent in 11.2004

I don’t think these die as often as the p80

Well presented, Mr packetfire.

The enlistment of s small child is a trick I hadn’t thought of!

I’m at 140k on an ‘04 XC70.

Why aren't exhaust made with exhaust grade PVC such as Schedule E?
