Replacing Petrol Engine Spark Plugs

Model: Volvo S70 MK 1 - Years 1996-2000
Part: Spark plugs

Disconnect the negative terminal of the battery. Remove the first spark plug cap. At the bottom of the well is the spark plug. Before proceeding with removal, clean the housing thoroughly with compressed air. Using a 16mm spark plug socket, gently insert it onto the spark plug head and unscrew it. Be careful not to drop any foreign objects into the well. Replace the spark plug with one of the same model, carefully inserting it into the well and gently turning it to ensure it screws in correctly. If you feel resistance, remove it and try again. Spark plugs should be tightened with a torque wrench; if you do not have one, tighten without overdoing it. Repeat the same procedure for the other spark plugs.
