TORQUE
CHARTS
A torque chart for fasteners is provided at the end
of each group (of service information). Refer to the Standard Torque Specifications chart to determine
torque values not listed in the group (Figs. 1 and 2).
It is important to be aware that the torque values
listed in the chart are based on clean and dry bolt

THREAD
IDENTIFICATION
SAE and metric bolt/nut threads are not the same.
The difference is described in the Thread Notation chart.
GRADE/CLASS
IDENTIFICATION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the line marks on the top of each bolt head (Fig. 1). The
actual bolt strength grade corresponds to the number
of line marks plus 2.
• A grade 2 bolt has no line marks on top of the bolt
head
• A grade 5 bolt has 3 line marks on top of the bolt
head • A grade 7 bolt has 5 line marks on top of the bolt

TOWING
RECOMMENDATIONS
When it is necessary to tow a Ram Truck, the rec
ommended method is either:
• the sling-type, rear-end raised towing method; or
• the wheel-lift towing method with a tow dolly lo
cated under the front wheels. A vehicle with flat-bed hauling equipment can also
be used to transport a disabled vehicle.

LUBRICATION
AND
MAINTENANCE
• A vehicle equipped with SAE approved sling-type
towing equipment can be used (Fig. 10). However,
many vehicles are equipped with air dams, spoilers, and/or ground effect panels. In this case a wheel-lift
towing vehicle or a flat-bed hauling vehicle is recom mended (Fig. 10). If a flat bed device is used, the ap
proach angle should not exceed 15 degrees.
GROUND CLEARANCE The lifted wheels of the disabled vehicle should be
a minimum of 10 cm (4 in.) off the ground. Make
sure there is enough clearance at the opposite end.
This is critical when towing over rough terrain. If necessary, the rear ground clearance can be increased by removing the wheels from the lifted end
and then towing with the lifted end closer to the
ground. If the rear wheels are removed, secure the
brake drums. A 20 cm (8 in.) ground clearance must
be maintained between brake drums or rotors and the ground.
SAFETY PRECAUTIONS The following safety precautions must be consid
ered when preparing for and during a vehicle towing operation:
• Remove exhaust pipe tips that interfere with the
tow sling and crossbar • Padding should be placed between the tow sling/
crossbar and any painted surfaces
• If the vehicle is damaged, secure the loose and pro
truding parts
• Always use a safety chain system that is indepen dent of the lifting and towing equipment
• When placing tow hooks on the rear axle, position them so they do not damage the brake tubing or
hoses
• Do not allow any of the towing equipment to con
tact the fuel tank
• Do not tow the vehicle by connecting to the front
or rear shock absorbers
• The operator should not go under a vehicle while
it is lifted by the towing equipment. The vehicle
should first be supported by safety stands
• Do not allow passengers in a vehicle being towed
• Observe all state and local laws involving warning signals, night illumination, speed, etc.
• Do not exceed a towing speed of 48 km/h (30 mph)
• Avoid towing distances of more than 24 km (15
miles) whenever possible • Do not attach tow chains or a tow sling to a
bumper, the steering linkage, the universal joints, or a drive shaft
REAR-END RAISED TOWING It is recommended that the rear-end raised towing
method be used. Vehicles can be towed with the front
wheels on the ground for extended distances at speeds not exceeding 48 km/h (30 mph) (Fig. 11). (1) Attach the J-hooks around the axle shaft tubes
outboard of the rear springs. (2) Position and center the sling under and for
ward of the rear bumper. (3) Attach safety chains (with pads) at each end of
the rear bumper.
(4) Turn the ignition switch to the OFF position to
unlock the steering wheel. (5) Clamp the steering wheel with the front wheels
in the straight ahead position.
CAUTION:
Do not use the steering
column

ACCEPTABLE
OIL
LEVEL
To maintain proper lubrication of an engine, the
engine oil must be maintained at an acceptable level.
For gasoline engines, the acceptable levels are indi cated between the ADD and
FULL
marks on oil
dip
stick. For Diesel engines, the acceptable levels are
indicated between the L (low) and H
(high) marks
on
oil dipstick. The oil level should be checked periodically. The
vehicle should be on a level surface. Wait for
five
minutes after stopping the engine. For gasoline en
gines,
add oil only when the level indicated on the
dipstick is at or below the ADD mark. For Diesel en
gines,
add oil only when the level indicated on the
dipstick is between the L and H marks.
Never oper

(1) With the engine idling, accelerate momen
tarily. The valve shaft counterweight should move CLOCKWISE.
(2) If no movement is observed, either the shaft is
binding or the thermostat spring is weak or broken. (3) If the thermostat spring is weak or broken, re
place the spring.
(4) Verify the manifold is COOL. Apply
MOPAR®Rust Penetrant (or an equivalent product)
to each end of the valve shaft at the bearings (Fig.
6).
(5) Allow the solvent to penetrate for a few min
utes.
Then, rotate the valve shaft back and forth un
til it turns without restriction.
AIR INJECTION SYSTEMS/AIR PUMP
Air injection system/air pump valves and switches
should be periodically tested for proper operation. In
spect the check valve tubing for corrosion. Replace it
if excessive corrosion exists.
CRANKCASE
VENTILATION
SYSTEM
All gasoline engines are equipped with a positive
crankcase ventilation (PCV) system. The PCV sys
tem prevents emission of residual engine oil vapor
from the crankcase (Fig. 7).

LUBRICATION
AND
MAINTENANCE
• SERVICE INFORMATION
All vehicles are equipped with a maintenance-free
(MF) battery when shipped from the factory (Fig. 10).
A maintenance-free battery does not have removable
cell caps and does not require additional water. Each MF battery has a visual battery condition in
dicator (Fig. 11). When an adequate battery charge
exists,
the indicator will have a GREEN dot. When
battery charging is necessary, the indicator will be dark. When the indicator is light brown colored or
yellow, the battery should be replaced.

tion procedure. (1) Disconnect the battery negative cable and then
the positive cable.
(2) Clean the battery cables and terminal posts
with a wire brush and a battery terminal cleaner. (3) Remove the battery holddown strap. Clean the
battery tray with a solution of baking soda and wa
ter. Rinse and dry the battery tray.
(4) Position the battery in the tray and install the
holddown strap. Do not over-tighten the nuts.
(5) Connect the battery positive cable and then the
negative cable to the battery.
(6) Apply a small amount of chassis lubricant (or
an equivalent protective coating) to the cable termi
nals.
RUBBER/PLASTIC
COMPONENTS
INSPECTION Components should be inspected at the same time
as scheduled underhood maintenance is conducted.
Rubber/plastic components should be replaced imme diately if there is any evidence of wear. Inspect the exterior surface of rubber hoses and ny
lon tubing for evidence of heat damage. The rubber
hose and nylon tubing located close to an exhaust
manifold should be given special attention. Verify
the nylon tubing located at these areas has not col lapsed.
