2004 DODGE RAM 2500 DIESEL tire pressure

If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL, or
diagonally across the hill.
When driving over sand, mud, and other soft terrain,
shift to low gear and drive steadily. Apply the accelerator
slowly to avoid spinning the wheels.
DO NOT REDUCE the tire pressures for this type of
driving.
NOTE:After off-road usage, particularly in sand or
mud, inspect the underside of the vehicle for accumu-
lated dirt at the propeller shaft, axles, U-joints, brake
rotors and calipers.
Use a hose to clean off any accumulation of dirt or mud.
Check the exhaust system and all exposed components
for any sign of damage.If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for im-
pacted material. Impacted foreign material can cause a
wheel imbalance. Removing the foreign material from
the wheels will correct the situation.
TRACTION
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.

hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
Hub Caps
The hub caps must be removed before raising the vehicle
off the ground.
For 2500/3500 single rear wheel (SRW) models, use the
blade on the end of the lug wrench to pry the cap off.
On 3500 models with dual rear wheels (DRW), you must
first remove the hub caps. The jack handle driver has a
hook at one end that will fit in the pry off notch of the
rear hub caps. Position the hook and pull out on the
ratchet firmly. The cap should pop off. The wheel skins
can now be removed. For the front hub cap on 3500models use the blade on the end of the lug wrench to pry
the caps off. The wheel skin can now be removed.
You must use the flat end of the lug wrench to pry off the
wheel skins. Insert the flat tip completely and using a
back and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off.
Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the
lugnut bolt circle and strike the high side down with a
rubber mallet. Be sure that the hub caps and wheel skins
are firmly seated around the wheel.
8-Stud Ð Dual Rear Wheels
Dual wheels are flat mounted, center piloted. The lug
nuts are a two piece assembly. When the tires are being
rotated or replaced, clean these lug nuts and add 2 drops
of oil at the interface between the hex and the washer.
306 WHAT TO DO IN EMERGENCIES

Cooling System
Cooling System Maintenance
At the intervals shown in the Maintenance Schedules
Section of the manual, the system should be drained,
flushed and filled.
Inspection
Coolant protection checks should be made every 12
months (prior to the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant as specified.
Inspect the entire cooling system for leaks. Check the face
of the radiator for any accumulation of bugs, leaves, or
other foreign matter. If dirty, clean the radiator core with
a garden hose. With the engine OFF, gently spray water
from the back of the radiator core. Check coolant bottle
tube for condition and tightness of connections at coolant
bottle and radiator.Check the coolant pressure cap and coolant bottle for
proper vacuum sealing. With the engine at normal oper-
ating temperature, note the level of the coolant in the
coolant bottle. Without removing the pressure cap (with
the engine off), drain a small amount of coolant from the
radiator drain cock. If the coolant level in the coolant
bottle drops, the system is sealing properly.
Extremely cold ambient temperature may require the
addition of a ªwinter frontº for effective operation of the
cab heating/cooling system. Make certain that a percent-
age of the radiator is exposed for adequate air flow
through the charge air cooler and automatic transmission
oil cooler. The percentage of opening must be increased
with the increasing ambient air temperature and/or
engine load. If the cooling fan can be heard cycling
frequently, increase the size of the opening in the winter
front.
MAINTAINING YOUR VEHICLE 343

²Off-road or desert operation.
²Extensive operation at high engine speeds (greater
than 2900 rpm) and loads (greater than 70% throttle).
NOTE:Most vehicles are operated under the conditions
listed for Schedule9B9.
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule9B9.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 15 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
²Drain water from the fuel filter.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the batteries and clean and tighten the termi-
nals as required.
