2. ENGINE LUBRI CATION AND SERVICE
2.1 ENGINE OIL VISCOSITY RECOMMENDATIONS
The grade of crankcase oil should be selected to give the best performance under the climatic and driving
conditions in the territory in which the vehicle is operated. When the crankcase is drained and refilled, the
crankcase oil should be selected, not on the basis of the existing temperature at the time of the change, but on the
ambient temperature range anticipated for the period during which the oil will be used.
Techline
2.2 ENGINE OIL CLASSIFICATION RECOMMENDATIONS
WH Series Models use 10W/30 SJ GF2 engine oil for general use and high ambient temperatures in both 3.8 litre
V6 and 5.7 litre GEN III V8 engines. This oil is also to be used for vehicles which operate for prolonged periods of
time in snow areas, however, if this oil is unavailable, 20W/50 viscosity grade oil may be used.
NOTE:
1. Non-detergent and low quality oils are specifically not recommended.
2. Only low phosphorous engine oils mus t be used. Just as lead can contam inate the ce ramic m onolith inside the
catalytic converter, so c an phos phorous . Mos t leading br ands of engine oil now limit phos phor us levels to “ s af e”
limits.
3. ‘Break-in’ oils, ‘tune-up’ compounds, ‘friction reducing’ compounds and other additives should not be used
unless recommended by Holden.
Their use will only increase operating costs and may contaminate the ceramic monolith inside the catalytic
converter, rendering it useless.
2.3 CHECKING ENGINE OIL LEVEL
CHECK
1. Ensure engine is at normal operating
temperature (idle for 10 minutes or equivalent).
2. Park vehicle on level surf ace (as this will af fect
the accuracy indicated on dipstick:- this is a
critical requirement).
3. Do not check oil level for at least 10 minutes
after engine shut down to allow oil to drain back
into the oil pan.
4. Remove dipstick and wipe clean.
5. Reinstall dipstick, ensuring that it is fully
seated. Slowly rem ove to avoid smearing, then
hold horizontally or with the lower end slightly
down, to avoid oil running along dipstick.
NOTE: Reinstall V6 engine dipstick with the
FULL/ADD marks facing towards centre line of
engine. This aspect is very important due to the
angle that the dipstick enters the oil in the oil pan.
6. Observe the oil level where it passes over the
centre line of the dipstick.
If the engine oil level is below the ADD mark on
the dipstick, using the specified engine oil (refer
2.2 ENGINE OIL CLASSIFICATION
RECOMMENDATIONS in this Section), top up
oil level until the oil reaches the full mark;
FULL mark on V6 engines.
Line after the hatched section on GEN III V8
engines.
7. When topping up the engine oil, allow
approximately 10 minutes for the oil added to
fully drain into the oil pan.

2.6 ENGINE VENTILATION SYSTEM
All WH Series Model engine ventilation systems,
use a P.C.V. valve and utilise engine vacuum to
draw blow-by gasses into the combustion
chambers where they are recycled through the
combustion process.
The location of the P.C.V. valve on a V6 engine is
in the inlet manifold, V6 superc har ged engine in the
LH rear of the s upercharger as sem bly, and G EN III
engine it is externally mounted between the valve
cover and the throttle body.
For service instructions covering the testing, and
the removal and reinstallation procedures of the
P.C.V. valve, depending on the engine variant,
refer to Section 6E1 EMISSION CONTROL - V6
ENGINE (V6 and V6 supercharged engines) or

2.7 FUEL FILTER
The fuel filter (1) is located on the pressure side of the high pressure fuel pump and is attached to the floor
pan of the vehicle, to the rear of the final drive assembly.
Refer to Fig. 0B-12 for filter locations.
The fuel filter must be replaced at the time or distance intervals specified in the Owner’s Handbook.
For service instructions covering the removal and installation of the fuel filter, refer to
Section 6C1 POWERTRAIN MANAGEMENT - V6 ENGINE
or
Section 6C3 POWERTRAIN MANAGEMENT - V8 ENGINE.
Figure 0B-12
2.8 AIR FILTER
The air filter may be partially cleaned of dust by
lightly tapping the elem ent. It should not be washed
or oiled. The tim e or dis tance intervals at which the
element requires servicing depend on vehicle
operating conditions. Under dusty conditions, the
element should be checked for restriction more
often than for normal city operation. Fig. 0B-13
shows a typical air cleaner assembly.
For service instructions covering the removal and
installation of the air cleaner element, refer to
Section 6C1 POWERTRAIN MANAGEMENT - V6

Figure 0B-14
2.10 COOLING SYSTEM
V6 AND V6 SUPERCHARGED ENGINE
The cooling system is filled initially with a coolant
mixture comprising 50% water and 50% inhibited
ethylene Glycol to Holden Specification HN 2043.
CAUTION: Do not remove the radiator cap
when the engine and radiator are hot. Scalding
fluid and steam can be blown out under
pressure if the cap is removed.
The cooling system is designed to use formulated
coolant (a mixture of inhibited ethylene glycol and
water), rather than plain water. The coolant solution
must be used year round.
Inhibited ethylene glycol conforming to Holden
Specification HN 2043 is named ‘New Formula
Long Life All Seasons Coolant’, and is available in
the following quantities:
1 Litre, P/N 92140054*
5 Litre, P/N 92140057*
20 Litre, P/N 92140055*
* Always check with the latest Holden spare parts
information for the correct part number before
ordering parts.
NOTE: Do not mix different types of anti-freeze or
corros ion inhibitors as they may be incom patible. If
a different type has been used in the cooling
system, flush the system with clean water.
The water used for mixing with inhibited glycol
concentrate must be of low dissolved salt content,
preferably tank water or demineralised water.
Check
Turn the coolant dipstick cap one eighth of a turn
anti-clockwise and slowly pull out the dipstick.
There are two triangles on the dipstick repres enting
the Minimum ▲ and Maximum ▼ levels.
When the coolant is cold, the coolant level should
be at or above the Minim um ▲ triangle m ark on the
dipstick. After the engine has been driven and the
engine is at the normal operating temperature, the
level should be somewhere between the Minimum
▲ and Maximum ▼ triangles.
If the coolant level is correct, replace the dipstick
and turn the cap one eighth of a turn clockwise to
secure.
If the coolant level is low, add enough of a pre-
mixed coolant solution of water and a good quality
inhibited ethylene glycol (meeting Holden
specification HN 2043) to bring the level up to the
proper mark.
When the level is correct, replace the dipstick and
turn the cap one eighth of a turn clockwise to
secure.
It is of the utmost importance to maintain the
correct concentration level of glycol in the cooling
system.
To ensure the specified glycol concentration is
maintained in the engine coolant, the coolant
concentration must be checked at the time or
distance intervals outlined in 7.2 MAINTENANCE
SCHEDULE in this Section or in the Owner’s
Handbook.
Check coolant concentration as outlined in
Section 6B1 ENGINE COOLING - V6 ENGINE or
Section 6B1-1 ENGINE COOLING - V6
SUPERCHARGED.
It is recommended that the coolant be drained, the
system flushed and refilled with clean water and
radiator coolant at the time or dist ance intervals set
out in 7.2 MAINTENANCE SCHEDULE in this
Section or as in the Owner’s Handbook.
T20B013
Figure 0B-15
Aluminium radiators should be protected at all
times by a coolant that is specifically recommended
for use with aluminium. Aluminium radiators may
be destroyed by the caustic solutions found in
some cleaners or the chemicals used in some
antifreeze’s and inhibitors.
For cooling system filling instructions, refer to
Section 6B1 ENGINE COOLING - V6 ENGINE or
Section 6B1-1 ENGINE COOLING - V6
SUPERCHARGED.
GEN III V8 ENGINE
CAUTION: Do not remove coolant surg tank
cap when the engine and radiator are hot.
Scalding fluid and steam can be blown out
under pressure if the cap is removed.
The cooling system is designed to use a specific
coolant (a mixture of DEX-COOL® coolant to GM
Specification 6277M coolant additive and water),
rather than plain water.
IMPORTANT: Do not use coolant other than DEX-
COOL®.
The use of this orange coloured coolant additive
also raises the boiling point and increases the
cooling system efficiency. For this reason, it is of
the utmost importance that the correct
concentration level of DEX-COOL® is maintained in
the cooling system.
Addition of plain water into the cooling system
when 'topping-up' may dilute the coolant m ixture to
a point where the specific properties of DEX-
COOL® become ineffective.
The coolant should comprise of a mixture 50%
DEX-COOL® (GM Specification 6277M) with 50%
clean, good quality water.
NOTE: Do not mix different types of antifreeze or
corros ion inhibitors as they may be incom patible. If
a different type has been used in the cooling
system, flush the system with clean water, refer to
Section 6B3 ENGINE COOLING - GEN III V8
ENGINE.
The water used for mixing with DEX-COOL®
coolant must be of low dissolved salt content,
preferably tank water or demineralised water.
Check
The coolant level can be externally checked at the
coolant recovery reservoir. With the engine cold,
the coolant level should be at the FULL COLD
mark on the front of the coolant reservoir.
Pre-mixed coolant (50% DEX-COOL® to GM
Specification 6277M with 50% clean, good quality
water) may be added as necessary to bring the
level shown on the coolant surg tank but only
when the engine is cold.
It is of the utmost importance to maintain the
correct concentration level of glycol in the cooling
system.
To ensure the specified glycol concentration is
maintained in the engine coolant, the coolant
concentration must be checked at the time or
distance intervals outlined in 7.2 MAINTENANCE
SCHEDULE in this Section or in the Owner’s
Handbook.
Check coolant concentration as outlined in Section
6B3 ENGINE COOLING - GEN III V8 ENGINE.
It is recommended that the coolant be drained, the
system flushed and refilled with clean water and
radiator coolant at the time or dist ance intervals set
out in 7.2 MAINTENANCE SCHEDULE in this
Section or the WH Series Owner’s Handbook.

destroyed by the caustic solutions found in some
cleaners or the chemicals used in some antifreeze’s
and inhibitors.
For cooling sy stem filling instructions, refer to Section
6B3 ENGINE COOLING – GEN III V8 ENGINE.
3. AUTOMATIC TRANSMISSION LUBRICATION AND SERVICE
3.1 RECOMMENDED FLUID
The automatic transmission for WH Series Models requires fluid qualified to Dexron® III (to Holden specification HN
2126).
3.2 CHECKING TRANSMISSION FLUID LEVEL
The transmission fluid level dipstick (1) is located
on the right hand side of the engine, refer to
Fig.0B-17.
1. Bring transmission to normal operating
temperature (82 - 94°C) (or drive vehicle for a
distance of 24km).
NOTE: As temperature affects transmission fluid
levels, this operation must be carried out with the
transmission at normal operating temperature. If
the vehicle is not at normal operating temperature,
and the proper checking procedures are not
followed, the result could be a false reading of the
fluid level on the dipstick.
2. Park vehicle on level ground.
3. Place selector lever in ‘P’ (PARK) position.
4. Apply park brake.
5. Let engine idle for three minutes with
accessories (i.e. air conditioning) turned off.
6. Lift the coloured dipstick locking lever, remove
dipstick and check fluid level.
The fluid level should be within the HOT
(hatched) area of the dipstick. If the level is
below this area, add only enough Dexron® III
fluid to bring the level into the HOT (hatched)
area of the dipstick.
NOTE 1: Inaccurate readings will result if the fluid
level is checked immediately after the vehicle has
been operating under an of the following conditions:
• In high ambient temperatures above 32°C.
• At sustained high speeds.
• In heavy city traffic during hot weather.
• Towing
• In commercial use (i.e. taxi).
If the vehicle has been operating under any of the
above conditions, switch of the engine and allow
the vehicle to cool for approximately 30 minutes,
then restart the vehicle and continue from step 2.
NOTE 2: The cold m arkings on the dipstick should
only be used as an indicator when initially filling the
transmission after the fluid has been completely
drained. The fluid should be rechecked when the
transmission is hot.
NOTE 3: Due to the shape of the filler tube, level
readings may be misleading. Look carefully for full
fluid ring on both sides of the dipstick. Recheck if
any doubt of fluid level occurs.
NOTE 4: Also check the fluid for contamination,
discolouration or if it smells burnt. This gives an
indication that frictional materials within the
transmission may need replacement. Refer to
Section 7C3 AUTOMATIC TRANSMISSION for
additional information.

4. BRAKE HYDRAULIC SYSTEM SERVICE
4.1 RECOMMENDED FLUID
The recommended fluid for the WH Series brake hydraulic system is heavy duty brake fluid to Holden’s
specification HN1796.
4.2 BRAKE FLUID LEVEL CHECK
Check that the fluid level is between the MIN and
MAX level markings on the translucent reservoir
housing.
NOTE: If the fluid is between the markings, do not
rem ove r eser voir c ap, as brake f luid expos ed to the
atmosphere will quickly absorb moisture.
Should the addition of fluid be required, wipe clean
the sides of the reservoir cover, then unclip and
rem ove the reservoir cap. T op up f luid using heavy
duty brake fluid to Holden’s Specification HN 1796.

6. POWER STEERING
6.1 RECOMMENDED FLUID
The recommended fluid for the WH Series power steering system is automatic transmission fluid, qualified to
Dexron ® III (to Holden specification HN 2126).
6.2 CHECKING POWER STEERING FLUID LEVEL
V6 AND V6 SUPERCHARGED ENGINE
The power steering fluid level is checked by
viewing the fluid through the transparent plastic
side of the reservoir (refer Fig.0B-22), which is
mounted to a bracket attached to the cooling fan
shroud.
If the fluid is cold, the level should be in the ‘COLD’
range. Sim ilar ly, if it is hot, the fluid s hould be in the
‘HOT’ range. If the fluid level is at the low side of
either range, f luid should be added to br ing the f luid
to the correct level.
Figure 0B-22
GEN III V8 ENGINE
With t he en gin e dress cov er remo v ed; the power
steering fluid level is checked in the same way as

steering pump.
With the en gine dress cover in stalled; chec k the
power steering fluid level by viewing the fluid
through the cut away in the engine dress cover at
the front of the engine.
The fluid level should be in the range of ‘Min cold’
and ‘max hot’ depending on the temper ature of the
fluid. If the fluid level is below the Min cold mark,
fluid should be added to bring the fluid to the
correct level.
T20B016
Figure 0B-23
6.3 PERIODIC SERVICING
Except under abnormal driving conditions (refer 7.1 ABNORMAL OPERATING CONDITIONS in this Section),
periodic draining of the power steering fluid is not necessary.
Check system for fluid leaks at every service. If there is evidence of leakage, repair leak and add fluid, if necessary,
to the correct level.
7. SERVICING
7.1 ABNORMAL OPERATING CONDITIONS
If the car is driven under any of the abnormal conditions listed below it is recommended that some items be
serviced more frequently than in the maintenance plan.
The extra services are only required while the car is driven under the abnormal conditions. If any of these conditions
are encountered on a one off basis, then any additional servicing should be for that time only. As a guide, if the car
is operated continually over a period of one month or 1000 km under the abnormal conditions, then additional
servicing may be required.
ABNORMA L CONDITIONS
A When driving less than 10,000 km in six months.
B Dust, dirt, loose road material.
C Muddy and wet areas.
D Cold weather (below 5°C) and when most trips are
less than 5km.
