Spark Arrestor
WARNING
Failure to heed the following warnings while servicing the spark
arrestor could result in serious injury or death.
Do not perform service on the spark arrestor while the system is
hot. Exhaust system temperatures can reach 1000° F. Allow
components to cool sufficiently before proceeding.
Remove any combustible materials from the area.
Wear eye protection and leather work gloves.
Do not stand behind or in front of the vehicle while purging.
Never run the engine in an enclosed area. Exhaust contains
poisonous carbon monoxide gas.
Never go under the vehicle while it’s inclined.
1. Remove the arrestor clean-out
plug (1) from the bottom of the
muffler.
2. Place the transmission in neutral
and start the engine.
3. Purge carbon from the system by
momentarily revving the engine
several times.
4. If carbon is expelled, cover or plug the
exhaust outlet (2) and rap on the pipe around
the cleanout plug while revving the engine several more times.
5. If particles are still suspected to be in the muffler, elevate the rear
of the vehicle one foot higher than the front. Set the parking brake
and block the wheels. Make sure the vehicle is in neutral and
repeat steps 3 and 4 until no more particles are expelled when the
engine is revved.
6. Stop the engine and allow the arrestor to cool. Reinstall the
arrestor plug and remove the outlet cover or plug.
