V70XC '99 Purge Valve Tools Required

RichSad · Post by **RichSad** » 31 Mar 2010, 09:46

Hi all, I am about to embark on my first self-repair on my Volvo. I've read here that the purge valve is an easy repair. I am wondering what tools I will need? If I need sockets or a wrench, I'll need to know what size. The part should arrive today and I'd like to get the tools and get this done!

I'd appreciate any special instructions I may need. I searched Google/YouTube and didn't find any Volvo-specific videos.

Which reminds me, is it worth investing in a Haynes or other manual for my car? Assuming I keep it I'd love to learn to do some repairs myself. I think I've heard that the manual for the 1999 doesn't cover the Turbo engine for some reason. Is that true? If so is it helpful anyway?

As always thanks for the help!
-Rich

From what I remember looking at the thing, you just pull off the 2 hoses and electrical connector and attach the new ones, no tools needed. If there are the retainer clips, you'll need a flathead screwdriver and a set of needlenose pliers.

Haynes? Yeah, probably worth it. There is only one for the old Volvo 850, but it's similar enough. In some ways, you might almost be better off with an S60 or 2001-x V70 manual. It was a lifesaver on my old Saab more than a couple times. I need to get one myself, it'd probably help with the "where the heck did that thing go?" moments.

The only Haynes manual I could find for my 98 V70 was a British version that doesn't cover the AWD. You might be as well off by locating and downloading the online 850 manual that is linked on this site somewhere.

Great suggestions on the manuals. Thanks. And you are correct, there appear to be no tools required to replace the purge valve beyond getting one of the tubes with a clip-thing on it off. How exciting for me... a repair I'm qualified to make myself! What's even more amazing is this may fix a very serious problem I've had since I bought the car (not starting after fillup).

Where is the purge valve located? I have a p0442 leak and I've changed out the gas cap and j hose at the evap canister. Thanks,

Radiator shroud near the battery. Follow the black hoses attached to the white one-way valves.

You can see it at the bottom left corner of this picture.

Thanks JBlackburn. Found it. Its in a little different place on a 99 V70. Would the purge valve cause a 442 error code? I find conflicting opinions. The hoses connecting the purge valve look like they could be replaced, lots of black carbon coming off when touched, but no visible cracks. I appreciate your help. Dan

It could be either. I would start by replacing the hoses back to the tank/canister - certainly cheaper than a new valve, and you may eliminate your problem.

Alternatively, you can have a shop do a smoke test on the EVAP system. That will help you see any leaks and what you actually need to replace rather than just guessing.

J, what do shops typically charge for a smoke test?

Post by **jblackburn** » 14 Sep 2011, 08:41

Probably whatever they charge for an hour of labor.
