acteristics than ethylene glycol. This can increase
cylinder head temperatures under certain conditions.
Propylene-glycol/Ethylene-glycol MixturesÐShould Not Be
Used in Chrysler Vehicles
Propylene-glycol/ethylene-glycol Mixtures can
cause the destabilization of various corrosion inhibi-
tors, causing damage to the various cooling system
components. Also, once ethylene-glycol and propy-
lene-glycol based coolants are mixed in the vehicle,
conventional methods of determining freeze point will
not be accurate. Both the refractive index and spe-
cific gravity differ between ethylene glycol and propy-
lene glycol.
CAUTION: Richer antifreeze mixtures cannot be
measured with normal field equipment and can
cause problems associated with 100 percent ethyl-
ene-glycol.
DIAGNOSIS AND TESTING - COOLING SYSTEM
LEAKS
ULTRAVIOLET LIGHT METHOD
A leak detection additive is available through the
parts department that can be added to cooling sys-
tem. The additive is highly visible under ultraviolet
light (black light). Pour one ounce of additive into
cooling system. Place heater control unit in HEAT
position. Start and operate engine until radiator
upper hose is warm to touch. Aim the commercially
available black light tool at components to be
checked. If leaks are present, black light will cause
additive to glow a bright green color.
The black light can be used in conjunction with a
pressure tester to determine if any external leaks
exist (Fig. 1).
PRESSURE TESTER METHOD
The engine should be at normal operating temper-
ature. Recheck the system cold if cause of coolant
loss is not located during the warm engine examina-
tion.
WARNING: HOT, PRESSURIZED COOLANT CAN
CAUSE INJURY BY SCALDING.
Carefully remove coolant recovery pressure con-
tainer cap and check coolant level. Push down on cap
to disengage it from stop tabs. Wipe inside of con-
tainer and examine lower inside sealing seat for
nicks, cracks, paint, dirt and solder residue. Inspect
radiator-to- pressure container hose for internal
obstructions. Insert a wire through the hose to be
sure it is not obstructed.Inspect cams on outside of pressure container. If
cams are damaged, seating of pressure cap valve and
tester seal will be affected.
Attach pressure tester (7700 or an equivalent) to
coolant pressure container (Fig. 2).

the wait-to-start indicator will be illuminated. The
indicator remains illuminated until the cluster
receives a wait-to-start lamp-off message indicating
that the pre-heat mode of the glow plugs has been
completed, until the ECM detects that the engine is
running, or until the ignition switch is turned to the
Off position, whichever occurs first.
The ECM continually monitors the engine coolant
temperature sensor to determine when the glow
plugs need to be energized in their pre-heat operat-
ing mode. The ECM then sends the proper wait-to-
start lamp-on and lamp-off messages to the
instrument cluster. If the instrument cluster turns on
the indicator after the engine is started, it may indi-
cate that a malfunction has occurred and that the
engine glow control system requires service. The
ECM will store a Diagnostic Trouble Code (DTC) for
any malfunction it detects. For proper diagnosis of
the engine coolant temperature sensor, the engine
glow control system and circuits, the ECM, the CAN
data bus, or the electronic message inputs to the
instrument cluster that control the wait-to-start indi-
cator, a DRBIIItscan tool is required. Refer to the
appropriate diagnostic information.
WASHER FLUID INDICATOR
DESCRIPTION
A washer fluid indicator is standard equipment on
all instrument clusters. However, this indicator is
only functional on vehicles equipped with an optional
washer fluid level switch integral to the washer
pump/motor unit on the washer reservoir. The
washer fluid indicator is located near the lower edge
of the instrument cluster, to the right of the multi-
function indicator display. The washer fluid indicator
consists of the International Control and Display
Symbol icon for ªWindshield Washer Fluidº imprinted
within a rectangular cutout in the opaque layer of
the instrument cluster overlay. The dark outer layer
of the overlay prevents the indicator from being
clearly visible when it is not illuminated. An amber
Light Emitting Diode (LED) behind the cutout in the
opaque layer of the overlay causes the icon to appear
silhouetted against an amber field through the trans-
lucent outer layer of the overlay when the indicator
is illuminated from behind by the LED, which is sol-
dered onto the instrument cluster electronic circuit
board. The washer fluid indicator is serviced as a
unit with the instrument cluster.
OPERATION
The washer fluid indicator gives an indication to
the vehicle operator that the fluid level in the washer
reservoir is low. This indicator is controlled by theinstrument cluster circuit board based upon cluster
programming and a hard wired input from the
optional washer fluid level switch that is integral to
the washer pump/motor unit. The washer fluid indi-
cator is completely controlled by the instrument clus-
ter logic circuit, and that logic will only allow this
indicator to operate when the instrument cluster
detects that the ignition switch is in the On position.
Therefore, the indicator will always be off when the
ignition switch is in any position except On. The indi-
cator only illuminates when it is switched to ground
by the instrument cluster circuitry. The instrument
cluster will turn on the washer fluid indicator for the
following reasons:
²Bulb Test- Each time the ignition switch is
turned to the On position the brake wear indicator is
illuminated by the instrument cluster for about two
seconds as a bulb test.
²Washer Fluid Level Switch Input- Each time
the cluster detects ground on the washer fluid switch
sense circuit (washer fluid level switch closed =
washer fluid level low) while the ignition switch is in
the On position, the washer fluid indicator is illumi-
nated. The indicator remains illuminated until the
washer fluid level switch input to the cluster is an
open circuit (washer fluid level switch open = washer
fluid level acceptable), or until the ignition switch is
turned to the Off position, whichever occurs first.
The instrument cluster continually monitors the
washer fluid level switch to determine the level of
the washer fluid. The instrument cluster logic applies
a delay strategy to this input to reduce the negative
effect that fluid sloshing within the reservoir can
have on reliable indicator operation. The washer
fluid level switch and circuit can be diagnosed using
conventional diagnostic tools and methods. For
proper diagnosis of the instrument cluster circuitry
that controls the washer fluid indicator, a DRBIIIt
scan tool is required. Refer to the appropriate diag-
nostic information.
WATER-IN-FUEL INDICATOR
DESCRIPTION
A water-in-fuel indicator is standard equipment in
all instrument clusters. The water-in-fuel indicator is
located near the lower edge of the instrument cluster,
to the left of the multi-function indicator display. The
water-in-fuel indicator consists of the International
Control and Display Symbol icon for ªWater In Fuelº
imprinted within a rectangular cutout in the opaque
layer of the instrument cluster overlay. The dark
outer layer of the overlay prevents the indicator from
being clearly visible when it is not illuminated. An
amber Light Emitting Diode (LED) behind the cutout

CYLINDER PRESSURE LOSS
If an increased pressure loss was found with the
cylinder leak test, inspect the engine by listening at
the cylinder head gasket, air intake area, exhaust, oil
fill opening and where injectors and glow plugs enter
the cylinder head. Also check the engine coolant in
the radiator or expansion reservoir for the formation
of bubbles.

It is possible to pin point the pressure loss of the
relevant cylinder by spraying with clean engine oil.
Engine oil seals off the gap between the piston and
cylinder wall briefly. If a reduced pressure loss now
occurs for a short time, the cause is very likely to be
the pistons, piston rings or cylinder contact surfaces
of the relevant cylinder.
Determining the cause can be falsified by the posi-
tion of the piston ring joints. If suspicion exists that
the loss of pressure is caused by the piston ring
joints being positioned directly one above the other,
fit the parts to the engine and repeat this test after
running the engine for a short time.
