2004 DODGE RAM 2500 DIESEL air filter

WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
CAUTION!
Diesel fuel will damage black top paving surfaces.
Drain the filter into an appropriate container.

or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts

procedures and specifications outlined in the appropriate
service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
cleaner for tightness. The air filter element must also be
clean and serviced according to the instructions outlined
in the Maintenance Schedule Section of this manual.Tampering With Noise Control System Prohibited
