Proper torque for sparkplugs S70 2000

What's the proper torque for changing plugs on a '00 S70 (2.4L)?

Also, I read several previous posts regarding the aluminum oil plug rings. My local Volvo dealership charges $1.25 each for those and I'm sure they can be purchased cheaper. Does anyone have any recommendations? I checked www.volvoparts.com but didn't find anything.

Thanks in advance.

Steve

    I just did the same job this past weekend. Surprisingly, this torque spec. is stated in the standard glovebox Owner's Manual.

    [From memory, for my '00 C70 LPT - I believe it was 18.7 ft. lbs. +/- 3 ft. lbs. and a 75mm gap on the plugs themselves - BUT PLEASE CHECK ME OUT ON BOTH]
    I haven't checked the link that used to give us access to the identical glovebox manuals online - but that's always an option if you don't have one.

    As always, I used a tad of anti-seize compound on the new threads as even the o.e. Volvo plugs were a tad difficult to remove at 28,094 miles and I don't want metal-to-metal adhesion or a broken plug later. What delayed me a few WEEKS was that I had to buy a 30T Torx drive SOCKET as I couldn't remove the 8 screws holding down the cover w/ a 30T Torx screwdriver.

      Your manual is available if you register at the Owner's Circle site at
      www.owners.volvocars.com
      in the 'Your Glovebox' section of the 'caring' dropdown

      From the manual
      Spark plugs: Champion RC8PYP (or equivalent)
      Spark plug gap: 0.03" (0.75 mm)
      Tightening torque: 18.4 ft. lbs. +/ 3.7 ft. lbs. (25 Nm +/ 5 Nm)
      Firing order: 12453
      Distributor ignition setting: Not adjustable

      Replacing spark plugs
      The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right type and use correct torque, see "Specifications". When changing the plugs, check that the suppressor connectors are in good condition. Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the terminals and the rubber seals.
