The distributor ignition system operates at very high voltages. Special safety precautions must be followed to
prevent injury. Always turn the ignition off when:
Replacing distributor ignition components e.g. plugs, coil, etc.
Do not touch any part of the distributor ignition system while the engine is running. This may result in
unintended movements and body injury.
Replacing spark plugs
The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving
may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right
type and use correct torque, see "Specifications". When changing the plugs, check that the suppressor connectors are in
good condition. Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the
terminals and the rubber seals.
