2 General Description
2.1 Radiator Assembly
The radiator has an aluminium core and is of the cross-flow design. Plastic side tanks are attached to the core by clinch
tabs. The clinch tabs are formed as part of the core assembly.
The lower frame of the radiator assembly is attached to the vehicle frame by two bolts supported in rubber mounts, pegs
are attached to the upper area of each side tank. These pegs are used to support the radiator with two rubber insert
mounting brackets.
A high temperature rubber seal is used to seal the mating surface between the core and each side tank. The seal(s)
must be replaced any time the side tank is removed from the core.
NOTE
The radiator core side tanks or transmission oil
cooler cannot be replaced separately. If there is a
fault with any of these components, the radiator
assembly must be replaced. Small core repairs
may be made using an aluminised silicon based
liquid repair agent. Refer to 3.15 Radiator in
this Section.
For vehicles with automatic transmission, a transmission oil cooler is located in the right-hand side radiator tank. The
cooler pipes from and to the transmission are connected to the oil cooler flexible hoses by means of quick connect
fittings.
The cooling fan motor is attached by three screws to the one-piece plastic fan shroud. In turn, the fan shroud is mounted
to the rear of the radiator and is located and supported by two bolts and two locating tabs. The upper clips lock the fan
shroud in place and can be released by hand to facilitate fan shroud removal. The shroud must be removed to allow fan
motor and blade assembly removal.
One harness connector is mounted to the upper section of the fan shroud allowing the fan motor and blade assemblies
to be removed individually from the shroud. The fan motor and blade is balanced as an assembly. These two
components are serviced only as a unit and are not to be separated.
The shroud, fan assembly and transmission cooler hoses can be removed and installed individually from the vehicle. For
removal and installation procedures, refer to 3.13Cooling Fan and Shroud Assembly, 3.14 Flexible Transmission
Cooler Hose and 3.15 Radiator in this Section.

COOLANT CONCENTRATION
Litres Of Coolant To Be Added
Concentration Reading % Automatic Transmission Manual Transmission
0 4.95 5.15
5 4.46 4.62
10 3.96 4.12
15 3.47 3.61

NOTE
If the reading is not clear, then properly clean
and dry the measuring surface, then conduct
another test. Also ensure that there is
sufficient fluid on the measuring prism.
9 If the reading shows that the concentration level of the coolant is inadequate, refer to the Coolant
Concentration table to determine the amount of
coolant that needs to be added to the coolant
recovery reservoir.
10 Start and run the engine until normal operating temperature is reached, to allow the added coolant
to be distributed throughout the engine cooling
system.

1 W ith the engine off, remove the coolant filler cap on
the coolant outlet housing, located at the front left-
hand side of the engine.

Figure 6B1 – 19
2 If filling a completely empty cooling system for automatic transmission models, mix 5 litres of clean
water with 5 litres of the recommended coolant or
5.2 litres of each for manual transmission models.
3 Add coolant via the engine coolant filler neck on the coolant outlet housing.
NOTE
Do not replace the coolant filler cap before
starting the engine (in step 6). Leaving the filler
cap off allows the engine to warm up without
pressurising.
4 Reconnect battery ground lead. Refer to 6D1 – 3 Battery – V6.
5 Start the engine and set the HVAC controls to: • Full hot
• Low fan
Figure 6B1 – 20
6 Run the engine at approximately 2,000 rpm to warm up the engine.
7 W ait until the radiator fan switches on.
8 W hen the radiator fan has switched on, let the engine rpm drop back to idle.
9 Turn the engine off when the radiator fan switches off.
10 Top up the coolant until full.
11 Replace the coolant filler cap.

Do not loosen or remove the radiator filler cap
when the coolant temperature is high. Steam
or boiling coolant will gush out and you may
be burnt. To open the radiator filler cap, cover
the filler cap with a thick cloth when the
coolant has cooled, release the pressure by
slowly turning the filler cap, and remove the
cap.
