MAINTENANCE
Muffler
WARNING
:
Failure to heed the following warnings while servicing the muffler could result in serious
injury or death.
• Do not perform service on the muffler 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 gloves.
• Do not stand behind or in front of the vehicle while purging.
• Never run the engine in an enclosed area. Exhaust can cause loss of consciousness or death in a very
short time.
• Never operate without the muffler.
• Never go under the vehicle while it's inclined.
Use the following procedure to periodically purge accumulated carbon from the exhaust pipe.
1. Place the transmission in neutral. Engage the park brake. Start the engine.
2. Purge accumulated carbon from the system by momentarily revving the engine several times.
3. If carbon is expelled,
partially
cover the exhaust outlet and rap on the pipe around the clean-out plug while
revving the engine several more times.
4. If particles are still suspected to be in the muffler, elevate the rear of the vehicle one foot higher than the front.
Block the wheels.
5. Repeat steps 3 and 4 until no more particles are expelled when the engine is revved.
6. Stop the engine. Allow the muffler to cool.
7. Reinstall the muffler plug and remove the partial outlet cover.
