Engine System - General Information - Leakage Test Using Smoke Test Equipment
General Procedures
CAUTION: The compressed air line supply pressure must be between 3.5 and 12 bar (50 and 175 psi) for the smoke test
equipment to function correctly. Do not exceed this pressure. Failure to follow this instruction may result in damage to the
smoke test equipment.
NOTES:
The vehicle battery must be in good condition and fully charged before carrying out this procedure.
On vehicles with 3.0L TDV6, it will be necessary to insert smoke at both air cleaner outlet pipes independently if the right
hand turbocharger and associated hoses are to be tested.
In some cases it may be necessary to remove undertrays, trim or engine covers to obtain access to all potential leak
locations.
Some variation in the illustrations may occur, but the essential information is always correct.
For further information regarding operation of the test equipment refer to the manufacturers operators manual supplied
with the kit.
1. WARNING: Use an additional support to prevent the hood
from falling if the smoke test equipment is secured to the
hood. Failure to follow this instruction may result in
personal injury.
Install the smoke test equipment to a suitable location
under the hood.
2. Connect a suitable compressed air line to the smoke test equipment.
3. Connect the smoke test equipment positive power cable to the battery
positive terminal.
4. WARNING: Do not connect the smoke test equipment negative
cable to the battery negative terminal.
Connect the smoke test equipment negative cable to a suitable body
ground point.

Engine Cooling - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Engine Cooling - Overview
Description and Operation
OVERVIEW
The engine cooling system maintains the engine within an optimum temperature range under changing ambient and engine
operating conditions. The system is a pressurized expansion tank system with continuous bleeds to separate air from the
coolant and prevent the formation of air locks. The engine cooling system also provides:
Heating for:
- The passenger compartment. For additional information, refer to 412-01 Climate Control.
- The throttle body.
Cooling for:
- The engine oil cooler. For additional information, refer to 303-01F Engine - 5.0L, Vehicles With: Supercharger or
303-01E Engine - 5.0L, Vehicles Without: Supercharger.
- The transmission fluid cooler. For additional information, refer to 307-02B Transmission/Transaxle Cooling -
5.0L/3.0L Diesel.
The primary components of the engine cooling system are the:
Coolant pump.
Thermostat.
Radiator.
Auxiliary radiator (SC (supercharger) vehicles only).
Cooling fan.
Expansion tank.
Engine oil cooler.
Outlet tube and heater manifold.
Connecting hoses and pipes.

System Operation
When the engine is running, the coolant is circulated around the engine cooling system by the coolant pump. From the coolant
pump, coolant flows through the cylinder heads and the engine oil cooler into the cylinder block and the heater manifold.
In the cylinder block, the coolant flows forwards to the outlet tube. When the coolant is cold, the thermostat is closed and the
coolant flows direct from the outlet tube back to the coolant pump. Once the coolant reaches operating temperature the
thermostat begins to open, to control system temperature, and coolant flows from the outlet tube to the coolant pump via the
radiator and, on SC (supercharger) vehicles, the auxiliary radiator. When the thermostat is open, the coolant flow through the
radiator(s) also generates a coolant flow through the transmission fluid cooler.
From the heater manifold the coolant flows through the electronic throttle and the heater core, in parallel circuits that are
unaffected by the position of the thermostat. From the electronic throttle, the coolant merges with bleed coolant from the
coolant pump and the outlet tube and flows to the expansion tank. From the heater core, the coolant flows back to the inlet of
the coolant pump.
Expansion and contraction of the coolant is accommodated by an air space in the expansion tank and the compliance of the
flexible hoses.
If the coolant level in the expansion tank decreases below a predetermined value, the level sensor connects a ground to the
instrument cluster, which activates the appropriate warning. For additional information, refer to 413-01 Instrument Cluster.
The cooling fan is operated by a fan control module integrated into the cooling fan motor. The fan control module regulates the
voltage, and thus speed, of the cooling fan motor in response to a PWM (pulse width modulation) signal from the ECM (engine
control module).
The cooling fan receives a battery feed and an ignition feed from the EJB (engine junction box). The ignition feed is supplied
from the main relay in the EJB, which is controlled by the ECM.
The ECM calculates the required fan speed from the engine temperature, A/C (air conditioning) system pressure and transmission fluid temperature. Under hot operating conditions, the fan may continue to operate for 4 minutes after the engine
has been switched off.
