2006 DODGE POWER WAGON engine

The radiator normally remains completely full, so there is
no longer a need to remove the coolant pressure cap
except for checking coolant freeze point or replacement
with new antifreeze coolant.
WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool an overheated engine! The coolant is under
pressure and severe scalding could result.
Drain, Flush And Refill
At intervals shown on the Maintenance Schedules, the
system should be drained, flushed and refilled. Refer to
your dealer or consult a service manual for proper
procedures.
Adding Coolant
When adding coolant, or refilling the system, a minimum
solution of 50% recommended HOAT ethylene glycol
engine coolant (antifreeze) and distilled water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below
34°F (
37°C) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
NOTE:It is the owner’s responsibility to maintain the
proper level of protection against freezing according to
the temperatures occurring in the area where the vehicle
is operated.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
386 MAINTAINING YOUR VEHICLE

When additional coolant is needed to maintain the
proper level, add the recommended concentration of
antifreeze and water to the coolant bottle. Do not overfill.
NOTE:Failure to follow the antifreeze concentration
and replacement recommendations, or failure to use
antifreeze formulated to prevent corrosion of all cooling
system metals, may result in radiator plugging, overheat-
ing, or cooling system leaks such as in core hole plugs.WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool an overheated engine. The coolant is under
pressure and severe scalding could result.
Recommended Engine Coolant
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.

CAUTION!
•Mixing of coolants other than specified engine
coolant, may result in engine damage, and de-
crease corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
•Do not use plain water alone or alcohol base
engine coolant (antifreeze) products. Do not use
additional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant and may plug the radiator.
•This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended.
Disposal Of Used Engine Coolant
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol-based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals and
children. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Pressure Cap
The coolant pressure cap must be fully tightened to
prevent the loss of coolant and to insure that the coolant
will return to the radiator from the coolant bottle. The
pressure cap should be inspected and cleaned if there is
any accumulation of foreign material on the sealing
surfaces.
388 MAINTAINING YOUR VEHICLE

The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” dot and an “MIN” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
MAX mark, because leakage may occur at the cap.
With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type.
WARNING!
Use of a brake fluid that may have a lower initial
boiling point, or is unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.

is on level ground, enough lubricant should be added to
bring the level to the bottom of the filler hole.
Lubricant Selection G56 (6 – Speed Manual
Transmission — If Equipped)
This transmission does not require periodic changing. If
it becomes necessary to add or change the fluid in this
transmission, refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
Automatic Transmission
Fluid Level Check
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. Operation of the trans-
mission with an improper fluid level will greatly reduce
the life of the transmission and of the fluid. Check the
fluid level whenever the vehicle is serviced.
Fluid Level Check – 545RFE
Check the fluid level while the transmission is at normal
operating temperature 82°C (180°F). This occurs after at
least 15 miles (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).

Required Maintenance for Noise Control Systems
The following maintenance services must be performed
every 6 months or 6,000 miles (9 600 km), whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed
or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and the cover is tight. Check all hoses leading to the
cleaner for tightness. The gasket between the air cleaner
housing and throttle body must be intact and in good
condition. The engine air cleaner filter must also be clean
and serviced according to the instructions outlined in the
appropriate maintenance schedule.
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.
Among those acts presumed to constitute tampering are
the acts listed below.
398 MAINTAINING YOUR VEHICLE

AIR CLEANER
•Removal of the air cleaner.
•Inverting the air cleaner lid.
•Removal of the air ducting.
EXHAUST SYSTEM
•Removal or rendering inoperative exhaust system
components including the muffler or tailpipe.

INTEGRATED POWER MODULE
An integrated Power Module is located in the engine
compartment near the battery. This center contains maxi
fuses and mini fuses. A label that identifies each compo-
nent is printed on the inside cover.
1. Disconnect the battery negative (-) cable before remov-
ing the cover.
2. Use specified fuses only.
3. Always properly reinstall the cover.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
