HSV Gen-F2 Maloo (2015-17)

Overview

Commencing production in early October 2015, the HSV Gen-F2 Maloo was available with GM’s 6.2-litre supercharged LSA V8 engine. While priority was initially given to LSA-powered production, supply of the LS3-powered Gen-F2 Maloo commenced in the first quarter of 2016.

Identification

From the front, the Maloo R8 LSA could be identified by its redesigned front fascia with subtle ‘splitter’ and pitch black bonnet vents. In profile, the Maloo R8 LSA had new five-spoke alloy wheels, pitch black door mirror scalps and fender vents, and new contoured side skirts. A new ‘vibrant ocean blue’ paint finish named Slipstream was also introduced.

Features

For the Gen-F2 Maloo R8, the auxiliary gauges at the base of the centre stack were discontinued to improve storage space, while HSV’s ‘Enhanced Driver Interface’ (EDI) was available as an extra-cost option.

2016 Maloo R8 SV Black

In June 2016, HSV commenced production of its final run of LS3-powered vehicles. The HSV Maloo R8 SV Black was released as part of this run and could be identified by its 20-inch ‘Satin Black’ alloy wheels, black AP Racing four-piston brake calipers, pitch black fender vents and mirror scalps, black door surrounds and lower door accents, shadow-chrome exhaust tips and black badging. Inside, the HSV Maloo R8 SV Black featured leather-clad sports bucket seats and unique sill and ID plates.

Production of the Maloo R8 SV Black was limited to 102 vehicles: 100 for Australia and two for New Zealand.

2017 HSV Gen-F2 Maloo R8 30 Years Anniversary

Production of the HSV Gen-F2 Maloo R8 30 Years Anniversary commenced in January 2017. Changes for the 30 Years Anniversary models included:

• A more powerful LSA engine (outputs increased to 410 kW and 691 Nm) with unique engine build plate; and,
• A modified bi-modal exhaust system in which the exhaust valve control was recalibrated to open earlier in the rev range.

Visually, the HSV Gen-F2 Maloo R8 30 Years Anniversary could be identified by its ’30 Years’ fender badges, ’30 Years’ rear window and ’30 Years’ floor mats. Furthermore, the HSV Gen-F2 Maloo R8 30 Years Anniversary had matte black accenting on its alloy wheels; as an option, 20 x 9.0J front and 20 x 10.0J rear ‘SV Rimfire’ five-spoke forged alloy wheels were also available.

As standard, the HSV Gen-F2 Maloo 30 Years Anniversary was equipped with a torque vectoring system. Previously introduced on the HSV Gen-F GTS, HSV’s brake torque vectoring reduced understeer by generating a ‘rotational moment’ in the rear axle during acceleration. Specifically, the ESC system detected understeer and applied the brake to the inner rear wheel to transfer torque to the outer rear wheel.

As an extra-cost option, the HSV Gen-F2 Maloo R8 30 Years Anniversary could also be specified with an AP Racing braking package (previously limited to HSV Gen-F GTS) which consisted of 390 mm by 36 mm floating two-piece front brake discs with forged six-piston callipers and 372 mm by 28 mm rear discs with four-piston callipers.

2017 HSV Gen-F2 GTSR Maloo

Production of the HSV Gen-F2 GTSR Maloo commenced in April 2017. Compared to the HSV Gen-F2 Maloo GTS, outputs for the HSV GTSR’s engine increased to 435 kW at 6150 rpm and 740 Nm at 3850 rpm, in part due to the fitment of a hi-flow K&N performance air filter. Like the HSV Gen-F2 30 Years range, the bi-modal exhaust system for the GTSR had a recalibrated exhaust valve control that opened earlier in the rev range.

Visually, the HSV Gen-F2 GTSR Maloo could be identified by its new front fascia with matte black accents and graphics, front splitter which extended around the lower edges, new daytime running lamps and wider front fenders (by 12 mm on each side) which featured horizontal fender vents. At the rear, the GTSR Maloo had a wider and lower rear diffuser, and quad exhaust outlets.

The HSV Gen-F2 GTSR Maloo had wider fenders to house the 20 x 9.0J front and 20 x 10.0J rear ‘SV Panorama’ five-spoke forged alloy wheels which had waisted spoke sides to reduce mass and a ‘Hyper Dark Stainless’ finish. Furthermore, the HSV GTSR Maloo had 410 mm fully-floating front brake discs with Ferodo 4488 brake pads and six-piston monoblock AP Racing calipers.

Inside, the HSV GTSR Maloo featured ‘HSV Podium’ seats that were finished in Alcantara and had diamond-quilted stitching and leather bolsters.

HSV E-Series I Maloo (2007-09)

Overview

Released in October 2007, the HSV E-Series I (E-I) Maloo R8 was a rear-wheel drive, performance utility. Manufactured in Elizabeth, South Australia, and finished by HSV in Clayton, Victoria, the E-Series Maloo range initially consisted of the Maloo R8 models which were powered by 6.0-litre LS2 V8 petrol engines. Transmission options consisted of the six-speed Tremec T56 manual and six-speed 6L80E automatic units. In April 2008, however, the 6.0-litre LS2 V8 engine was replaced by the more powerful 6.2-litre LS3 V8. Furthermore, the Tremec T56 six-speed manual transmission was replaced by the TR6060 unit in October 2008.

LS2 and LS3 V8 engines

The all-aluminium, Generation IV 6.0-litre LS2 pushrod V8 engine had a 101.6 mm bore, 92.0 mm stroke, flat-topped pistons, cast-steel roller rocker arms, roller cam followers, coil pack ignition, two valves per cylinder and a compression ratio of 10.9:1; maximum engine speed was 6500 mm. Although calibrated to run on 95 RON premium unleaded petrol (PULP), the LS2 engine could also run on 91 RON unleaded petrol with a small loss in power. For the E-Series, the LS2 engine introduced a recalibrated engine control module (with a ‘limp home’ mode) and new tubular extractors which fed into a twin-exhaust system with four outlet pipes.

Compared to the LS2 engine , the 6.2-litre LS3 V8 engine had a 103.25 mm bore (stroke was unchanged at 92.0 mm), a stronger block, higher-flow cylinder heads and injectors, hollow-stem intake valves, new pistons, a more aggressive camshaft with 14.0 mm lift, a new intake manifold and a lower compression ratio of 10.7:1. As a result of the LS3’s introduction, the six-speed automatic transmission was also recalibrated for faster gearshifts.

Dimensions and suspension

Compared to the Z-Series Maloo , the E-Series Maloo was 150 mm longer (at 5040 mm), 57 mm wider (1899 mm), 30 mm taller (1480 mm) and had a 71 mm longer wheelbase (3009 mm). Furthermore, the E-Series Maloo had MacPherson strut front suspension and four-link, independent rear suspension.

HSV E-Series III Maloo (2010-13)

Overview

Released in September 2010, the E-Series III (E-III) Maloo introduced an updated interior with additional features. The 6.2-litre V8 engine was also available with a dual-fuel liquid propane injection (LPI) system which provided identical performance to the petrol-only V8. The LPI engine would start on petrol but switch to LPG for low and mid-range driving; from approximately 5300 rpm – depending on conditions – the engine would revert to petrol for full power.

Inside, the E-III Maloo R8 was fitted with a new ‘Oracle’ dashboard with binnacle gauges and piano black trim on the centre console and steering wheel; there was also an ‘Enhanced Driver Interface’ with a touch-screen display that could provide performance data.

August 2012 update (‘MY12.5’)

In August 2012, the range was expanded with the introduction of an entry-level Maloo and peak power for the Maloo R8 was increased to 325 kW.

Features: Maloo R8

Standard features for the E-III Maloo were extended to include satellite navigation (with touchscreen), iPod connectivity and a reversing camera.

From August 2012, the Maloo R8 was fitted with 20-inch ‘SV Performance’ forged alloy wheels (finished in Blade Silver) and leather seats as standard.

Features: Maloo

Compared to the pre-August 2012 Maloo R8, the standard Maloo was similarly equipped, but fitted with 20-inch ‘Pentagon’ alloy wheels and omitted the Enhanced Driver Interface.

20 Years of Maloo

To coincide with the E-III Maloo, a limited run ’20 Years of Maloo’ edition was released; these models were distinguished by their 20-inch GTS alloy wheels, bonnet scoops, bi-modal exhaust system and blind spot alert.

Recalls: HSV Z-Series Maloo

Overview

Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

Recalls: HSV Z-Series Maloo

• In September 2005, a recall was issued for HSV Z-Series Maloo due to a potential wiring harness routing and retention condition that could interfere with the driver’s foot when applying the brake pedal. The recall applied to a specific range of base/level 1 VZ models (PRA 2005/8059).
• In March 2006, a recall was issued for HSV Z-Series Maloo models manufactured from 1 April 2003 to 2 December 2005 that were fitted with front seat-mounted side airbags. The electrical earth wire fitted underneath either front seat could become detached, potentially causing an electrostatic charge to transfer through the seat and causing unintended deployment of the front side airbag when the vehicle was stationary and while an occupant was exiting one of the front seats (PRA 2006/8380).
• In March 2006, a recall was issued for HSV Z-Series Maloo models built from 1 May 2004 to 30 July 2004 due to the incorrect fitment of a plastic clip to the plenum panel. If fitted, the circular clip could contact the engine fuel feed hose, potentially causing a fuel leak and fire hazard (PRA 2006/8407).

HSV Z-Series Maloo: LS2 V8 engine

Overview

With the exception of the early 5.7-litre LS1 V8 engines, General Motors’ LS V8 engines are regarded as being generally reliable. However, they may experience the problems described below.

Hydraulic lifter failure

For GM’s LS V8 engines, the hydraulic lifters may fail due to:

• A failed plunger within the lifter itself. When the plunger fails, it cannot maintain oil pressure and remains in a collapsed state – the lifter therefore cannot take up valve lash such that a tapping noise is heard that increases in volume and frequency with engine speed;
• The spring mechanism jamming – this is more common in older engines;
• Inadequate lubrication of the lifter roller wheel surface causing friction on the lobe (this generally results in a squeaking noise);
• Softened valve springs which also require replacement; or,
• Worn lifter buckets.

A failed hydraulic lifter can bend the pushrods which can then fall out of the space between the rocker arm and the top of the lifter. Once a pushrod falls out of that space, it may cause broken rocker arms, broken valves, cracked heads, a damaged cam or total engine failure.

It is recommended that the lifters be replaced every 100,000 kilometres, though failure of the hydraulic lifters is more common in engines with high-lift camshafts because higher spring pressure are required to prevent valve float, putting extra pressure on the lifter. Replacing the lifters requires that the cylinder heads be removed such that new head gaskets and head bolts are required.

Hydraulic lifter noise

From cold start-up, the hydraulic lifters may make a tapping noise. The most common cause of hydraulic lifter noise is particles in the engine oil becoming jammed between the lifter plunger and the lifter body, causing the plunger to become stuck down. The clearances between the plunger and body of a hydraulic lifter can be as little as 3 microns (0.003 mm) such that any particle larger than this in the oil can jam the lifter plunger in its body.

Lifter noise may also be caused by aeration of engine oil in the lifter’s pressure chamber since this increases valve closing velocity. Aeration of engine oil may be caused by:

• air in the higher pressure chamber of the lifter affecting valvetrain lash;
• air that is ingested into the lifter during a cold start due to a suction side leak at the oil pump or oil pump pick-up tube O-ring; or,
• low oil levels and high engine speeds.

Once air gets into the high pressure chamber, it will be slowly expelled through the narrow clearance of the plunger and body.

Rocker bearing failure

The rocker bearings – which sit on top of the valve train and transfer energy from the pushrod to the valve – can develop a sideways slop which can damage the valve tops, the rocker or valve springs. Furthermore, the rocker bearings can split such that the needle bearings fall out and end up in the oil pan.

Trunion bearing upgrade kits can be installed in the factory rockers which reduce sideways movement and provide a better range of vertical movement. Alternatively, after-market roller rockers can be installed which have better geometry than the standard rockers and control the valve more precisely via the centre of the valve tip.

Valve spring failure

The LS engine has ‘beehive’, single valve-type valve springs (as opposed to a dual valve spring which has a smaller spring inside the primary spring) and, in rare cases, the valve spring may break at its top where the coils are tightly wound. If a single valve-type valve spring breaks, it is common for the valve to be dropped, causing significant engine damage; sometimes, however, the valve may be held up by the valve locks when the spring is breaks. Symptoms of broken valve spring include:

• Engine vibrations;
• Loss of power beyond 4000 rpm;
• Misfire under load; and,
• Constant misfire.

If the vehicle is driven with a broken valve spring, a valve may come into contact with the piston, causing the valve to be bent. Furthermore, if the valve head breaks off, the engine will seize. To fix a failed valve spring, the cylinder heads need to be removed so that a new valve, head gasket and head bolts can be fitted.

For durability, it is recommended that high rpm are avoided when the engine is cold.

Problems and faults: HSV Z-Series Maloo

• The HSV Z-Series Maloo’s starter motor may work intermittently due to components in the Powertrain Interface Module (PIM) being susceptible to static; a revised PIM was subsequently released.
• For models with automatic transmissions, thudding noises during gear changes may be due to worn shift solenoids.
• A rattling noise from the steering column when driving at highway speeds or on coarse roads may be due to the steering column adjuster spring vibrating against the steering column housing – a cable tying the two sides of the spring together may alleviate the problem.
• The fuel gauge may provide inaccurate due to a bent fuel float or faulty sender unit.
