air filter RAM CHASSIS CAB 2007 User Guide

• If the filter is not damaged, remove all snow/ice,
reinstall filter and reset the Filter Minder™.
A visual inspection of the air cleaner filter element is
never recommended under normal circumstances. A
badly restricted element may appear clean while a soiled
element may be quite effective in filtering particles
without restricting air flow. Rely on the Filter Minder™
to determine when a filter change is necessary.
After a new filter element is inserted, press the rubber
button on the top of the Filter Minder™. This action will
reset the yellow disc to the clean position.
CAUTION!When using an engine cleaner or a degreaser, be sure
to wrap and tape the Filter Minder™ to protect the
plastic housing from damage and discoloration. CAUTION!Many aftermarket performance air filter elements do
not adequately filter the air entering the engine. Use
of such filters can severely damage your engine. MAINTAINING YOUR VEHICLE 409

the filter, counterclockwise and allow any accumulated
water to drain. Leave the drain valve open until all water
and contaminants have been removed. Close the drain
valve, by turning it clockwise, when clean fuel is visible.
NOTE: The Fuel / Water separator drain valve is
located on the bottom of the fuel filter housing.
If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
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. MAINTAINING YOUR VEHICLE 411

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. WARNING!Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.
CAUTION!Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.
NOTE: A maximum blend of 5% biodiesel, meeting
ASTM specification D-6751 may be used with your
Cummins Diesel equipped vehicle. Use of bio-diesel412 MAINTAINING YOUR VEHICLE

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
should be tight and in good condition. Damaged compo-
nents, burned or blown out mufflers, burned or rusted
out exhaust pipes should be replaced according to the
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 air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions out-
lined in the Maintenance Schedule Section of this
manual.
Tampering With Noise Control System Prohibited
Federal law prohibits the following acts or the causing
thereof: (1) the removal or rendering inoperative by any
person, other than for purposes of maintenance, repair, or
replacement, of any device or element of design incorpo-
rated into any new vehicle for the purpose of noise
control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the vehicle
after such device or element of design has been removed
or rendered inoperative by any person.446 MAINTAINING YOUR VEHICLE

Among those acts presumed to constitute tampering are
the acts listed below.
• AIR CLEANER
Removal of the air cleaner.
Removal of the air cleaner filter element from the air
cleaner housing.
Removal of the air ducting.
• EXHAUST SYSTEM
Removal or rendering inoperative exhaust system
components including the muffler or tailpipe.
• ENGINE COOLING SYSTEM
Removal or rendering inoperative the fan clutch.
Removal of the fan shroud. Noise Emission Warranty

Once a Month
• Check tire pressure and look for unusual wear or
damage.
• Inspect the batteries and clean and tighten the termi-
nals as required.
• Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
• Check Filter Minder™. Replace air cleaner filter
element if necessary.
• Check all lights and all other electrical items for correct
operation.
• Drain water from the fuel filter. At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect the brake hoses.
• Inspect the U-Joints ( if equipped) and front suspen-
sion components.
• Check the automatic transmission fluid level.
• Check the manual transmission fluid level.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends (4X4) models only.
• Lubricate Front Drive Shaft Fitting ( 4X4).
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts. MAINTENANCE SCHEDULES 475
