Spark Plug Service
Recommended Spark Plug:
BPR6ES (NGK)
W20EPR-U (DENSO)
To insure proper engine operation, the spark plug
must be properly gapped and free of deposits.
WARNING
If the engine has been running, the muf-
fler will be very hot. Care must be taken
not to touch the muffler when removing
the spark plug.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug
base.
3. Use the wrench supplied with the water pump
to remove the spark plug.
4. Visually inspect the spark plug and discard if
the insulator is cracked or chipped.
3. Clean with a wire brush if the spark plug is to
be reused.
4. Measure the plug gap with a feeler gauge.
5. Correct as necessary by carefully bending the
side electrode.
The gap should be: 0.70—0.80mm (0.028-
0.031 in.)
8. Check to make sure the spark plug washer is in
good condition.
9. Thread the spark plug in by hand to prevent
cross-threading.
10. After the spark plug is seated, tighten with the
spark plug wrench to compress the washer.
If installing a new spark plug, tighten 1/2 turn
after the spark plug seats to compress the
washer. If reinstalling a used spark plug, tight-
en 1/8-1/4 turn after the spark plug seats to
compress the washer.
CAUTION
The spark plug must be securely tightened. An
improperly tightened spark plug can become
very hot and could damage the engine.
Never use spark plugs which have an improper
heat range. Use only the recommended spark
plugs or equivalent.

off or stop position.
2. Disconnect suction and discharge hoses to pre-
vent damage during transport.
3. Let the engine cool before transporting.
4. Keep the water pump level to prevent fuel
spillage.
5. Take care not to drop or strike the water pump
when transporting.
