Spark Plug Service

Recommended spark plugs:

NGK – C5HSB or CR5HSB

DENSO – U16FS-UB or U16FSR-UB

NOTICE

Incorrect spark plugs can cause engine damage.

1. Disconnect the spark plug cap, and remove any

dirt from around the spark plug area.

2. Remove the spark plug with a 5/8-inch spark

plug wrench.

3. Inspect the spark plug. Replaceit if the

electrodes are worn, or if the insulator is

cracked or chipped. Clean the spark plug with a

wire brush if you are going to reuse it.

4. Measure the spark plug electrode gap with a

suitable gauge.

Plug gap: 0.024 - 0.028 in (0.60 - 0.70 mm)

Correct the gap, if necessary, by carefully

bending the side electrode.

5. Make sure the sealing washer is attached and

install the spark plug carefully, by hand, to

avoid cross-threading.

6. After the spark plug seats, tighten witha

5/8-inch spark plug wrench to compress the

washer.

If reinstalling the used spark plug, tighten

1/8 - 1/4 turn after the spark plug seats.

If installing a new spark plug, tighten 1/2 turn

after the spark plug seats.

NOTICE

A loose spark plug can overheat and damage

the engine. Overtightening the spark plug can

damage the threads in the cylinder head.
