V70 P0455, P0440, P0442 Fix with Photos

Finally got fed up with the host of evap codes on my 1998 V70 AWD and went ahead and replaced the canister hoses, rollover valve hoses, purge valve (and surrounding hoses), and the three inches of rubber line connecting the small vent filler tube to the hard plastic line coming from top of fuel tank. I didn’t order any special hoses, rather went to Autozone and bought a variety of molded J and U hoses (they were kind enough to let me go the back and pick out what I needed).

MVS Contributor Eric aka deepsouth has had it. He can’t take it anymore. So he got out his tools and got to work.

rollover valve - P0455, P0440, P0442 Fix

Finally got fed up with the host of evap codes on my 1998 V70 AWD and went ahead and replaced the canister hoses, rollover valve hoses, purge valve (and surrounding hoses), and the three inches of rubber line connecting the small vent filler tube to the hard plastic line coming from top of fuel tank. I didn’t order any special hoses, rather went to Autozone and bought a variety of molded J and U hoses (they were kind enough to let me go the back and pick out what I needed).

  1. I started with the Evap Canister (to the left of the front driver’s wheel when looking at the car head on). Use a 10mm wrench to remove the small bolt at the bottom of the canister and drop the canister down. Some folks have talked about removing the fender skirt to gain access, but I didn’t find that necessary.
  2. I eliminated the large air hose #21 by using small piece of power steering line (gotta use what you have on hand) and a plastic inline connector from AZ (see photo).
  3. I used two molded molded U hoses and hose clamps to connect the lines coming from the tank and the purge valve (hoses #16 and #4).
  4. Next, I followed the purge line up to the purge valve (checking the integrity of the hard plastic line) and swapped it out as well ($39 part number 911-800 from AZ). The purge valve (#11) is directly behind radiator under air duct (see photos).
  5. Next, I removed the carpeted rear doors (10mm bolts) that hide the spare tire, removed the carpet, and gained access to the fuel line/filter access panels. One of the panels is underneath the wiring harness (held on by two plastic retaining clips). Remove the retaining clips and flip wiring harness out of the way.
  6. It is necessary to remove both access panels in order to gain access to the small piece of rubber tubing that connects the small metal vent filler tube to the plastic vent line from the top of the fuel tank (This 3″ hose was a PITA to replace).
  7. Finally I removed the hoses from the rollover valve, doubled checked the integrity of the plastic valve, and replaced lines with generic 1/4 inch AZ fuel line and hose clamps. (Again, see photos).

Total cost of job was around $55. Over 1500 miles and no more evap codes. I’ve tried to label the individual photos below. Good luck!

My Evap Setup.  I used generic parts from AZ to replace most hoses.

Bonus! More About The Volvo v70


Late in 1996, Volvo introduced a new estate car to the market, the V70.

The Volvo V70 was developed from the concept of the successful 850 Estate which had then been on the market since February 1993.

The exterior of the new V70 showed softer styling than its predecessor, but still carried a strong Volvo identity including the typical almost vertical rear end. Inside the car, the dashboard was new, as was most of the interior. As regards safety, a number of important improvements were also made.

An interesting and successful addition to the V70 models was the all-wheel drive XC 70 models.

The Volvo V70 was produced until 2000, when it was replaced by the second-generation V70.
