1. Remove the spare wheel, jack, and tools from storage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. For 2500/3500 4x2 series trucks, when changing a
front wheel, place the bottle jack under the frame rail
behind the wheel. Locate the jack as far forward as
possible on the straight part of the frame.
For 2500/3500 4x4 series trucks, when changing the front
wheel, assemble the jack drive tube to the jack and
connect the drive tube to the extension tube. Place the
jack under the axle as close to the tire as possible with the
drive tubes extending to the front. Connect the jack tube
extension and wheel wrench.When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle between the
spring and the shock absorber with the drive tubes
extending to the rear. Connect the jack tube extension and
wheel wrench.
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.

4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on 2500/3500 single rear
wheel (SRW) models. On 3500 dual rear wheel models
(DRW) the lug nuts are a two piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until the
vehicle has been lowered.

Drain a small amount from the fuel/water separator
filter monthly or when the WATER IN FUEL indicator
lamp is on. Turn the drain valve, located on the bottom of
the filter, counterclockwise and allow any accumulated
water to drain into an approved container. 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.
