Change spark plugs
The spark plugs should be changed every 30,000 miles (50,000 km).
However, city driving or fast highway driving may require changing after 7,500 miles of driving.
When fitting new plugs, be sure to fit the right type:
Engine B21F : Volvo Part No. 273594-2 (Bosch WR7DS) or equivalent. Engine B21A: Volvo Part No.
273592-6 (Bosch W7DC) or equivalent. Engine B 21 FT : Volvo Part No. 273594-2 (Bosch WR7DS) or
equivalent. Engine B23E: Volvo Part No. 273591-8 (Bosch W6DC) or equivalent. Torque to 7-10 ft. lbs.
When changing the spark plugs, check that the suppressor connectors are in good condition. Cracked or
damaged connectors should be replaced.
When changing spark plugs, clean the cables and cable terminals, also the rubber seals. If the car is
driven on roads where salt is used during the winter, coat the cables with silicone.
