FUEL LEVEL SENDERS

REFILLING
To prevent air from being trapped in engine block, engine
should be running when refilling cooling system. After system is full,
continue running engine until thermostat is open, then recheck fill
level. Do not overfill system.
TESTING
THERMOSTAT
1) Visually inspect thermostat for corrosion and proper
sealing of valve and seat. If okay, suspend thermostat and thermometer
in a 50/50 mixture of coolant and water. See Fig. 1. Do not allow
thermostat or thermometer to touch bottom of container. Heat water
until thermostat just begins to open.
2) Read temperature on thermometer. This is the initial
opening temperature and should be within specification. Continue
heating water until thermostat is fully open and note temperature.
This is the fully opened temperature. If either reading is not to
specification, replace thermostat.

CAUTION: If turbocharger failure exists, intercooler must be cleaned.
See INTERCOOLER under AIR INDUCTION SYSTEMS.
Removal
1) Disconnect negative battery cables. Disconnect air inlet
tube and exhaust pipe from turbocharger. Disconnect intercooler inlet
duct from turbocharger. See Fig. 2.
2) Disconnect and plug turbocharger oil supply line and
turbocharger oil drain line at turbocharger. Remove turbocharger
retaining nuts, turbocharger and gasket from exhaust manifold. Plug
all air intake openings.
Installation
1) Apply anti-seize compound on turbocharger mounting studs.
Using NEW gasket, install turbocharger. Install and tighten
turbocharger retaining nuts to specification. See TORQUE
SPECIFICATIONS.
2) Using NEW gasket, install turbocharger oil drain line on
turbocharger. Install and tighten turbocharger oil drain line bolts to
specification. See TORQUE SPECIFICATIONS.
CAUTION: Turbocharger must be pre-lubricated by pouring clean engine
oil in turbocharger oil supply line fitting on turbocharger
before starting the engine.
WARNING: DO NOT rotate turbine wheel in turbocharger with your finger,
as sharp edges may exist.
3) Pour 3 ozs. (60 cc) of clean engine oil into turbocharger\
oil supply line fitting on turbocharger while using soft object to
rotate turbine wheel in turbocharger. This must be done to pre-
lubricate the turbocharger.
4) Install turbocharger oil supply line on turbocharger and
tighten nut to specification. See TORQUE SPECIFICATIONS. To install
remaining components, reverse removal procedure. Tighten bolts/nuts to
specification. See TORQUE SPECIFICATIONS.
TURBOCHARGER WASTEGATE ADJUSTMENT
NOTE: For turbocharger wastegate adjustment, see CONTROL ROD
ADJUSTMENT under TURBOCHARGER WASTEGATE in ON-VEHICLE
ADJUSTMENTS - DIESEL article.
ENGINE SENSORS & SWITCHES
ENGINE COOLANT TEMPERATURE SENSOR
Removal & Installation
1) Engine coolant temperature sensor is located at front of
cylinder head near thermostat. See Fig. 3.
2) Partially drain cooling system until coolant level is
below the cylinder head. Disconnect ECT sensor electrical connector.
Remove ECT sensor from cylinder head. Discard "O" ring. To install,
reverse removal procedure. Use new "O" ring.
CRANKSHAFT POSITION SENSOR (CKP)
NOTE: Crankshaft Position (CKP) sensor may be referred to as engine\
speed sensor.
Removal & Installation
1) CKP sensor is located on left rear side of engine block

1) Partially drain cooling system. Engine coolant temperature
sensor is located on front of intake manifold, near inside of
generator and contains a Tan/Black wire and a Black/Light Blue wire in
the electrical connector.
2) On 3.9L, remove engine cover and air cleaner housing from
inside of vehicle for access to engine coolant temperature sensor. On
5.2L and 5.9L, engine coolant temperature sensor may be serviced from
front of vehicle without removing engine cover and air cleaner
housing.
3) On all models, disconnect electrical connector at engine
coolant temperature sensor. It may be necessary to use a coat hanger
and fabricate an "L" shaped tool about 8" (203 mm) long to disconnect
electrical connector by placing hook part of tool under electrical
connector and pulling electrical connector upward from engine coolant
temperature sensor. Remove engine coolant temperature sensor.
Installation
To install, reverse removal procedure. Tighten engine coolant
temperature sensor to specification. See TORQUE SPECIFICATIONS. Fill
cooling system.
FUEL LEVEL SENSOR
Removal & Installation
See FUEL LEVEL SENSOR under FUEL SYSTEM.
INTAKE AIR TEMPERATURE (IAT) SENSOR
NOTE: Intake air temperature sensor may also be referred to as
intake manifold air temperature sensor.
Removal & Installation (Dakota, Durango & Ram Pickup)
1) IAT sensor is screwed into the intake manifold. See Fig. 4
, 5 or 6. Remove air inlet duct or air cleaner assembly for access to
IAT sensor if necessary. Disconnect electrical connector at IAT
sensor. Remove IAT sensor from intake manifold.
2) To install, reverse removal procedure. Tighten IAT sensor
to specification. See TORQUE SPECIFICATIONS.
Removal & Installation (Ram Van & Ram Wagon)
1) IAT sensor is screwed into the intake manifold. See Fig. 5
. On 3.9L, remove engine cover and air cleaner housing from inside of
vehicle for access to IAT sensor. On 5.2L and 5.9L, IAT sensor may be
serviced from front of vehicle without removing engine cover and air
cleaner housing.
2) On all models, disconnect electrical connector at IAT
sensor. Remove IAT sensor from intake manifold. To install, reverse
removal procedure. Tighten IAT sensor to specification. See TORQUE
SPECIFICATIONS.

* READ THIS FIRST *
Before preforming maintenance on vehicle, ensure that all
cautions and warnings have been observed to prevent vehicle damage or
personal injury. See CAUTIONS & WARNINGS in MAINTENANCE INFORMATION
article in this section.
Introduction
The frequency of scheduled inspection and maintenance
services in this article are based on normal vehicle usage ONLY. The
following Severe conditions are NOT taken into account:
* Frequent short driving less than 5 Miles (8 Km).
* Frequent driving in dusty conditions.
* Frequent trailer towing.
* Extensive idling.
* More than 50% of your driving is at sustained high speeds
during hot weather, above 90
F (32C).
If the vehicle is operated mainly under any of these
conditions, this Normal service schedule article is inadequate. DO NOT
USE. Instead, use the Severe service schedule: See
