engine coolant DODGE RAM SRT-10 2006 Service Repair Manual

COOLER & LINES-OIL
DESCRIPTION
An engine oil cooler is used on all models. The cooler is a coolant-to-oil type and mounted on the right front inner
fender.
OPERATION
Engine oil travels from the oil pump and filter to the oil cooler via an oil supply line. The oil is cooled and returned
to the engine via an oil return line. Engine oil is then pumped into the main oil gallery. Engine coolant flows into the
cooler from the heater return hose and exits into the water pump inlet nipple.
STANDARD PROCEDURE - OIL COOLER LINE QUICK CONNECT FITTING
DISASSEMBLY/ASSEMBLY
DISASSEMBLY
1. Remove dust cap by pulling it straight back off of
quick connect fitting (1).
2. Place disconnect tool (4) onto oil cooler line with
the fingers of the tool facing the quick connect fit-
ting (1).
3. Slide disconnect tool down the line and engage the
fingers of the tool into the retaining clip. When
properly engaged in the clip, the tool will fit flush
against the quick connect fitting.
4. Rotate the disconnect tool 60° to expand the
retaining clip.
5. While holding the disconnect tool against the quick
connect fitting, pull back on the oil cooler line to
remove.

ASSEMBLY
1. Align oil cooler line (3) with quick connect fitting (1)
while pushing straight into the fitting.
2. Push in on oil cooler line (3) until a “click” is heard
or felt.
3. Slide dust cap (4) down the oil cooler line (3) and
snap it over the quick connect fitting (1) until it is
fully seated and rotates freely. Dust cap (4) will
only snap over quick connect fitting (1) when the
cooler line (3) is properly installed.
NOTE: If dust cap will not snap into place, repeat
assembly step #2.
REMOVAL
1. Disconnect oil cooler coolant hoses (3).
2. Disconnect throttle body air inlet hose, remove air
cleaner housing assembly (Refer to 9 - ENGINE/
AIR INTAKE SYSTEM/AIR CLEANER HOUSING -
REMOVAL).

in. lbs.).
3. Connect oil supply (1) and return lines (2) to oil
cooler and.
4. Connect oil cooler coolant hoses (3).
5. Install air cleaner housing assembly, connect throt-
tle body air inlet hose (Refer to 9 - ENGINE/AIR
INTAKE SYSTEM/AIR CLEANER HOUSING -
INSTALLATION).
6. Fill cooling system (Refer to 7 - COOLING/ENGINE

8.3L - SRT-10
1. Disconnect the electrical connector to the MAP
sensor (2) and Coolant Temperature sensor (3).
2. Release fuel system pressure. Refer to Fuel Pres-
sure Release Procedure in this section.
3. Disconnect negative battery cable.
4. Remove the air cleaner assembly, refer to the
Engine/Air Intake System/Air Cleaner Housing for
more information.
5. Disconnect the electrical connector to the TPS (1)
and Idle Air Control.

6. Connect the electrical connector to the MAP sensor and Coolant Temperature sensor.
7. Connect the electrical connector to the TPS and Idle Air Control.
8. Install the wiring harness to the wiring clips under the throttle body.
9. Connect fuel supply tube to fuel rail. Refer to Quick Connect Fittings inthe Fuel Delivery section.
10. Install the negative battery cable.
11. Install the air cleaner assembly, refer to the Engine/Air Intake System/Air Cleaner Housing for more information.
12. Use the DRBIII
scan tool ASD Fuel System Test to pressurize the fuel system. Check for leaks.

Battery voltage (12 volts +) is supplied to the injectors through the ASD relay. The ASD relay will shut-down the 12
volt power source to the fuel injectors if the PCM senses the ignition is on,but the engine is not running. This
occurs after the engine has not been running for approximately 1.8 seconds.
The PCM determines injector on-time (pulse width) based on various inputs.

5.7L V-8
The 2-wire Intake Manifold Air Temperature (IAT) sen-
sor is installed in the intake manifold (2) with the sen-
sor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coef-
ficient (NTC) sensor. Meaning, as intake manifold tem-
perature increases, resistance (voltage) in the sensor
decreases. As temperature decreases, resistance
(voltage) in the sensor increases.
OPERATION
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the density of the air
entering the intake manifold based upon intake manifold temperature. At key-on, a 5–volt power circuit is supplied
to the sensor from the PCM. The sensor is grounded at the PCM through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
Injector pulse-width
Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge temperatures)
The resistance values of the IAT sensor is the same as for the Engine CoolantTemperature (ECT) sensor.

WARNING: The fuel injection pump supplies extremely high fuel pressure toeach individual injector
through the high-pressure lines. Fuel under this amount of pressure can penetrate the skin and cause per-
sonal injury. Wear safety goggles and adequate protective clothing. Do not loosen fuel fittings while engine
is running.
WARNING: Engine may start while cranking starter motor.
DRAINING FUEL TANK - DIESEL
Due to a one-way check valve installed into the fuel fill opening fitting atthe tank, the tank cannot be drained con-
ventionally at the fill cap.
1. Raise vehicle.
2. If vehicle is equipped with 4 doors and a 6 foot (short) box, remove left-rear tire/wheel.
3. Thoroughly clean area at top of fuel tank around fuel tank module.
4. Loosen clamp and disconnect rubber fuel fill hose at tank.
5. Drain fuel tank by attaching drain hose from an approved diesel fuel draining station to the fuel fill fitting of tank.
