Maintenance

To remove a spark plug:

(1)Remove the hood. (See page 27 for hood removal and installation procedures.)

(2)Remove the spark plug cap.

(3)Remove the spark plug, and then check the condition of the spark plug and the spark plug gap. If the electrode portion is significantly discolored, if electrode ero- sion becomes excessive, if carbon and other deposits are excessive, or if the spark plug gap is not within the specified range, replace the spark plug.

TIP:

When the engine is operating normally, the color of the spark plug electrode portion will be a medium-to-light tan.

Specified spark plug: B7HS

Spark plug gap:

0.6–0.7 mm (0.024–0.028 in)

To install a spark plug:

(1)Wipe off any dirt from the threads, insula- tor, and gasket surface of the spark plug.

(2)Install the spark plug, and then tighten it to the specified torque.

Tightening torque: Spark plug:

25.0 Nm (2.55 kgf-m, 18.4 ft-lb)

TIP:

If a torque wrench is not available when you are installing a spark plug, a good estimate of the correct torque is 1/4 turn to 1/2 turn past finger tight using the spark plug wrench included in the tool kit. Have the spark plug adjusted to the correct torque with a torque wrench as soon as possible.

(3)Wipe off any water or dirt inside the spark plug cap.

(4)Install the spark plug cap by pushing it down until it is securely installed in its original position.

(5)Install the hood in its original position.
