1999 V70 XC EVAP j-hose location

Dmaxx25 · Post by **Dmaxx25** » 02 Mar 2014, 12:28

I have searched multiple forums endlessly trying to find the definitive location of the EVAP canister on my 99 V70 XC only to find locations for other years of XC's. I even purchased a VADIS dvd but it only works on windows xp and was of no help. So please help me with the actual location of the EVAP canister so I can replace the j-hose and the charcoal canister filter. The P0442 code used to come on and I did everything else I could on the list with this being the last thing. I've had the parts for over a year now and recently moved back to Washington from Hawaii, so im gonna have to pass emissions to register the car. Does anyone know the location for sure? any help wou;ld be amazingly appreciated!

Well, find the purge valve under the radiator plastic lip, and just follow the vacuum hoses!

On my 99, it behind the right rear wheel, just forward of the gas tank

Did you find it Dmaxx25? I can't locate the j-hose on my 99 v70XC either! It's definitely not where the tutorials show it to be (behind the right rear wheel).

I have not needed to work on mine but this may be it?

98V70 AWD. The canister in my car is located under the battery at the driver's side. You can see it as a squarish box from underneath the car. Don't remove battery, no access from that side. In my case access to the top of the charcoal canister was achieved by removing the plastic housing where the blinker light is. Flashlight and little hands needed. The "big" hose on top was my problem, it sort of fell apart. I'm guessing the 99 XC is more like that rather than having the canister near the rear.

Thanks, I'll check that out this weekend. Someone knocked that blinker off my car when it was parked, and I started to get the EVAP errors, so you might be onto something!

I just recently replaced my J-hose on a 1999 V70xc. It is located above the gas tank in the rear. The easiest way to get at it is to remove the bolt on the fuel filter and either move it out of the way or remove it all together. Then you will be able to look in and see the back of the charcoal canister. The clamps weren't easy to remove but some patience and a small flat head screwdriver will do the trick. I did a smoke test first with a homemade smoke tester and this revealed all the leaks in the system. Good luck!

Very interesting. I've been rained out every weekend lately, so I haven't had a chance to look. How did you make/set up your homemade smoke tester?

aquamann: I've been needing a smoke machine. Can you share how you made the homemade tester? Thanks!

I made my smoke tested out of a plastic bucket that has a rubber o-ring inside the cover. I got it from the grocery store. It had pickled meat in it but any bucket with a gasket in the lid will work. I drilled two 2 inch holes in the lid. I used 4 quick connects that are used on pneumatic tools, 2 male and 2 females. Applied a bit of Teflon tape to the male ends first and screwed them down tight. On one of the fittings i connected a 5 foot piece of clear tubing with a plastic fitting that comes with tire pumps used to fill air mattresses. On the inside of the same fitting i put a 2 inch piece of clear tubing. In the short piece of tubing I stuck a Colt cigar( I nipped off a bit of the filter so it would fit inside the bucket) and lit it with a blowtorch. I snapped the lid on tight and used my aid compressor to blow a small amount of pressure into the other fitting, making the cigar smoke backwards, blowing a steady stream of smoke out through the air mattress filling nozzle. Turn your regulator on your compressor down to a bare minimum. I could stop the air flow by putting my finger over the air fill nozzle. From there I connected to the evap line up by the radiator and had someone blow shot puffs into it as I followed the line all the way back to the gas tank. I found a leak at the j-hose and at the line on the filler neck that allows air into the charcoal canister. I had a crack in the j-hose and the purge valve was stuck in the open position allowing gas to evaporate through the 2 spots even when the car sat over night. After fixing both things I smoke tested again and everything was tight and the top of the bucket swelled a bit from pressure and some leaked out around the lid of the bucket which was good because you should only be using low pressure anyway. It worked so well I geared up a large rubber plug that fits in the filler neck and used this to test the gas tank for leaks. Found one at one of the sending units. I got about 2 minutes of burn time out of each cigar, which was plenty long enough to find the leaks. I hope you find this as useful as I did. And all for under ten bucks! Happy hunting.
