The door that locks to secure the gas cap on the passenger side of the vehicle should have a spring in it to keep it closed, or open. The spring rate is zero on my car. Thus the door does not always shut far enough for the lock to secure it closed. I have the replacement spring from drivewire, but lack the knowledge of how to replace the spring that is there. I need more help. Thanks! Richard

 

You need to replace the Gas door Hinge to get it working properly.

 

is it a simple un bolt and replace, rebolt process for the hinge?

 

Is there a site I can buy that from?

 

I too, have to do this, while my gas cap will currently close the plastice hinge is cracked and it's only a matter of time before it will not work.

 

The hinge is locked in by plastic pins. You will have to knock the center out then the hinge will fall off.
Then you will have to install the new one.
Not to sure about a site. I think we might have covered this before.
Do a search for Gas door hinge and see what returns. I think they might have posted a site to buy as well.

 

Is there a hinge from any other model that is interchangable with the S80 hinge I need? I can not locate it for this model. Thanks again Tech.

 

The S80/S60/V70 2001 and newer all use the same hinge.
Best bet might be the Dealer.

 

Hinge was $13.08 from the dealer and spring another 4. A few minutes of labor on my part and the door is now secure. For future help, you push the pins outside the fender into the fender right? There was no need to dig behind the carpet to get to the hinge. With the fender sheet metal, you could not get to it if you had to. I removed the rubber gasket around the filler hose for the gas tank for no need. It really is simple. Thanks tech for the help again.

 

Yes you just knock the pins in and not worry about them.
Then new one comes with them.

Glad you got it fixed.
