DODGE RAM 1500 GAS 2006 3.G Owners Manual

Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership. 
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
4 x 2 Models
The ball joints and seals should be inspected whenever
the vehicle is serviced for other reasons.
MAINTAINING YOUR VEHICLE 441
7

The ball joints originally supplied with the vehicle are
permanently lubricated at the factory and do not require
service. However, if the seals on the ball joints are
damaged, the joints should be replaced. Serviceable
replacement ball joints are available.
Front suspension ball joints should be replaced only by a
qualified service technician using tools specially de-
signed for this purpose. Damage to the joints and/or
suspension components may result if improper replace-
ment procedures are used.
If seals are damaged the ball joints should be replaced to
prevent leakage or contamination of the grease.
Steering Linkage — Inspection
Whenever the vehicle is hoisted, all steering linkage
joints should be inspected for evidence of damage. If
seals are damaged, parts should be replaced to prevent leakage or contamination of the grease. Lubricate the
steering linkage regularly according to the “Maintenance
Schedule” in this manual.
Half-shaft Constant Velocity Joints
All four- wheel- drive 1500 models are equipped with
four constant velocity joints. Periodic lubrication of these
joints is not required. However, the joint boots should be
inspected for external leakage or damage periodically. If
external leakage or damage is evident, the joint boot and
grease should be replaced immediately. Continued op-
eration could result in failure of the joint due to water
and dirt contamination of the grease. This would require
complete replacement of the joint assembly. Refer to the
Service Manual for the detailed replacement procedure.

Front Prop Shaft Lubrication — 2500/3500 (4X4)
Models
Lubricate the front driveshaft grease fitting at each oil
change listed in the appropriate Maintenance Schedule
for your vehicle (Schedule “A” and “B”). Use Mopar 
type MS-6560 (lithium based grease), or equivalent.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, tailgate and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.

Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers
The fluid reservoir is located under the hood and should
be checked for fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not ra-
diator antifreeze). When refilling the washer fluid reser-
voir, take some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will help
blade performance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
444 MAINTAINING YOUR VEHICLE

After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Mopar All
Weather Windshield Washer Solution, used with water as
directed on the container, aids cleaning action, reduces
the freezing point to avoid line clogging, and is not
harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to Exhaust Gas in the Safety Tips section of this
manual.
Exhaust System Rubber Isolator and Loop-Type
Hanger — If Equipped
Inspect surfaces whenever the vehicle is hoisted for
rubber to metal separation or deep cracks. SLIGHT
MAINTAINING YOUR VEHICLE 445

CRACKING DUE TO WEATHERING DOES NOT AD-
VERSELY AFFECT PERFORMANCE. If, however, exces-
sively deep localized cracks are present, or any part of the
exhaust system abnormally contacts the underbody hard-
ware, the isolator and/or hanger should be replaced.
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
Check engine coolant (antifreeze) protection every 12
months (before 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.
For 3.7L, 4.7L, and 5.7L engines, check the coolant bottle
hoses for condition and tightness of the connections at
both the coolant bottle and radiator.
Coolant Level ( 3.7L, 4.7L, 5.7L Engines)
The coolant reserve system provides a quick visual
method of determining that the coolant level is adequate.
With the engine idling, and warmed to the normal
operating temperature, the level of the coolant in the
coolant bottle should be between the fluid level marks.
Check the coolant level whenever the hood is raised.
446 MAINTAINING YOUR VEHICLE

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.
MAINTAINING YOUR VEHICLE 447
7

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. If a non-
HOAT coolant is introduced into the cooling sys-
tem in an emergency, it should be replaced with
the specified 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.
448 MAINTAINING YOUR VEHICLE

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.
WARNING!
The warning words “DO NOT OPEN HOT” on the
radiator pressure cap are a safety precaution. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
MAINTAINING YOUR VEHICLE 449
7

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
Brake System
Power Disc Brakes (front and rear)
Disc brakes do not require periodic adjustment.
Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure. 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.
