Will a regular VZ Commodore REAR sway bar fit a VZ Adventra? What about a FRONT one?

SUMMARY: Can I reduce body roll by doubling the front sway bar? Since I raised the suspension on my VZ Adventra LX6, using Kings Springs, I have had one problem: in a tight corner, the outer front wheel dips down really noticeably. This would be body roll, except that the rear doesn't dip as...

I recently acquired 2nd hand a black coloured vanity plate (rear license plate surround) for my silver Adventra. These were standard on the CX models, but it looks great on my LX. Changes the whole look of the rear for the better. It's made of plastic, and the paint has been scratched off...

Last week, I noticed that the A/C cold air wasn't quite as cold as it should be. Then, the day after my 120,000 km service, the engine (or compressor - couldn't tell) would shudder every minute or so, but only when idling with the A/C on. A/C off = no shudder. A couple of days after that...

I just had the 120,000 km service done on my beloved Adventra. For such an important service, I took it to Holden; it was a little pricey but they were very thorough. They changed the spark plugs, of course. Since then, I've noticed: - less visible exhaust - more torque - poorer fuel...

VZ Adventra LX6 My rear passenger side power window has stopped working. I can't remember the last time it was used. Neither the centre console switch or the door switch will activate it. Is it worth trying to fix this myself? Where should I start looking?

My Adventra (Alloytec 190) is coming up to 120,000 km and I don't know if/when the spark plugs were changed, so it might be a good idea to do so. The engine runs well, but a little rich. (Long Term Fuel Trim is usually about -7% to -9%) When I replace the plugs, should I replace the coil...

***SORRY - title should be USEFUL VZ ADVENTRA UPGRADE - but I can't change it? I recently fitted a trans cooler to my VZ Adventra, and OZnick (who had done the same previously) raised the desirability of putting some mesh in the lower opening. There's no protection there, and other exposed...

Ever since my radiator blew up, I've never been happy with the cooling system on my VZ Adventra. The radiator fans are powerful enough, but I don't like the way the ECU controls them. Basically, it does *absolutely nothing* with the fans until everything is TOO BLOODY HOT - ****! (like 109...

Does anyone know what the Volumetric Efficiency of the Alloytec 190 is? (I want to put it into DashCommand)

I'm currently researching engine cooling systems, and I found this in Wikipedia: "On many automobile engines, including all Chrysler Group and General Motors products, the thermostat does not restrict flow to the heater core. The passenger side tank of the radiator is used as a bypass to the...

A while ago, I was talking to a bloke from Octane Alley in Geelong, where they modify Alloytecs for racing. He was very generous with his time & we had a long conversation about the extensively modified intake manifold he had developed. He had done a lot of flow-testing, and had made major...

For those who use DashCommand: The Version 7 series has some major upgrades from version 6, including Text Alerts/Advisories and an All-New ENGINE dashboard! Yes, it's a hobby now. It was designed for my own use in my 2005 VZ Holden Adventra LX6, but it will suit most Alloytec Holdens and...

After many delays, I finally fitted a transmission cooler to my VZ Adventra LX6. Wow! Big difference in engine temperature. It now runs cooler generally, heats up more slowly, and cools more rapidly. I know this because I monitor the temperature using DashCommand to interpret the OBD-II...

I've done a DashCommand setup for my VZ Adventra LX6. It's nearing the end of its development (currently up to v7.44), and it's getting a bit fancy. I haven't released any of the version 7 series yet, and I want to polish it before I do. I like some opinions on the short descriptions I have...

I'v mucked around with my beloved Adventra's suspension so much I've forgotten where I started! Could someone with standard suspension (preferably not sagged) and standard 225/55R17 tyres please measure: (a) height (mm) from ground to body, just forward of the rear wheel well (b) height...

When I was getting some suspension work done, I had them put in one of those Nolathane Diff Inserts. Sounded like a good idea. Unfortunately, the combination of this, the upgraded front bushes and my Adventra's self-levelling rear shocks (pneumatic) has made the rear very harsh under certain...

I know that information on Thermostats & Fan Temperatures has been posted before. What I don't know is if the V6 Adventra cooling system is any different to an ordinary VZ cooling system. The Adventra has the 190kW V6, but it's the version with two pulley belts and the alternator on the...

For those of you who like that sort of thing, I'll share my VZ V6 Adventra Dash for use with the DashCommand system. All you need is an Android tablet (it's probably too detailed for a phone), and OBD-II interface, and the DashCommand program. I've tried a lot of OBD-II software, and...

I seriously love my Adventra. It drives like you own the road, and feels like it can go anywhere (even though that's not quite true). It's amazingly rock solid on gravel, dirt & wet roads, and it's so roomy that sleeping in it is like being in a big capsule hotel. Still, it was a failure in...

I always had the impression that my Adventra's rear window should pop right open (I mean wide open, to the max) when I press the remote open button (or the button bizarrely hidden inside the glovebox). Instead, what it's always done is to pop a little, and you have to encourage it a fair bit of...

I've usually run 95 or 98 RON in my Adventra LX6, to keep the engine clean, and to try to get better economy. I had an ECU tune (by the guy who is reputed to be the gun at this), and asked about whether it could be tuned to run optimally on 95 or 98. "It'll be tuned to whatever's in the...

Newbie question. I've seen a lot of after-market vented/fluted guards for sale. A lot of people install them for the look; I get that. But, installed in a standard Commodore or Adventra, would they actually DO anything useful? What is behind the vented panel? Would you need air ducts to the...

Browsing for Adventra parts, I found this: Holden VZ Adventra V6 24V Dohc 2005 09 Conversion Gasket SET EEH5130 10 | eBay It says it's a "conversion gasket set". Conversion to what?

When the Adventra first came out, there was a Holden By Design (HBD) option for off-road use; 16-inch wheels with suitable tyres. Does anyone know the specs (code) of the tyres? More of a legal question than a technical one.

The saga of my 2005 VZ Adventra continues. I became entranced with idea of under-drive pulleys, bought PBK-007 20% underdrive kit, supposedly the right one. But it won't fit, because some VZ Adventras, like mine, have a twin belt setup, with a 2-track harmonic balancer. Powerbond...

Geez, my Adventra is giving me a lot to deal with this month. Latest thing is a whining noise under the bonnet on start-up. It lasts for about 5 minutes if the car hasn't had a run for a day or so, otherwise, it disappears quickly. Today, after a quiet weekend at home cleaning out the...

Does anyone know of a mechanic in the Western Sydney / Blue Mountains area who is honest, and good with Alloytecs? I'm starting to lose faith in the local guy. He's honest and forthright, and good with simple stuff, but his young workers are a bit careless, and I'm starting to think that...

Bad news for me. My radiator split open last week, and I had to get towed home. The local mechanic fixed the radiator, but said it failed the pressure test & was leaking coolant from the back of the engine. Said it was probably the thermostat housing; come back next week. He looked at that...

OK, this one is a bit technical, but I'm curious to know if the information is out there. The Alloytec 190 intake manifold plenum has valves which close at 4000RPM to shorten the runner length, increasing induction by adjusting resonance (Helmholtz effect). For simplicity, let's call...

I recently obtained a VZ sump guard from 4Blok for my VZ Adventra. It's pretty thin (1mm) galvo, but it was cheap and I mainly wanted it to help clean up the under-body airflow, so no problem. I also figured I could use it as a template if I needed to get a heavier one made. Holden...

My beloved 2005 VZ Adventra LX6 has an Electronic Stability Program. This makes it heavy in the steering, and when driven it feels like it's on rails. I've recently tried driving with ESP turned off, and find that I prefer it! The car steers much more easily, is much easier to park, feels...

Can anyone tell me which wire is which on the VZ MAF connector plug? Yes, I have searched and searched...

I had my Adventra tuned today by a company that has been recommended by many on this forum. It runs great! Quieter, noticeably more acceleration, smoother etc. But then, on my third trip after the tune, the "Check Powertrain" alert came on! Any ideas? How do I proceed? (The auto...

This one was a mystery to me until I asked accentstencil, who clued me in. So I thought I'd share the wisdom. If you are blessed with self-levelling suspension, then every now and again - in my Adventra manual, it says every 45,000 km - you are supposed to replace the "Self-Levelling...

One of the air shocks used by my Adventra's self-levelling suspension has an oil (?) leak. It looks like it's been leaking for a while; not a huge amount, but noticeable. There's a little sludge built up on the outside. How serious is this? One of my friends who saw it said "Don't worry -...

Since it's coming up to 95,000 km, I'm about to take my beloved Adventra in for its first service since I took ownership a few months ago. I plan to get everything done that's listed for 95k, and to be on the safe side, I want to change all the fluids: oil, auto trans, coolant and maybe even...

I've been happily monitoring my Adventra with a cheapo Scantool adapter and the excellent Torque program, among others. However, my adapter does not do SW-CAN, the proprietary GM network protocol. Additionally, there are quite a few parameters that it can't read from the ECU. I'm wondering...

Just sharing an experience.... I fitted a Growler CAI, and the Mace Engineering 12mm Intake Manifold Insulator, and trying to get just a little more efficiency, I replaced the stock Alloytec 190 intake tube, which has 2 resonator tubes, with one from an Alloytec 175, which lacks them ($20...

Having done a few mods to my Alloytec 190, I'm getting interested in manifolds. I know there's : (a) the stock 190 manifold (b) the CPR6 performance manifold (c) the Octane Alley performance manifold But what about the American manifolds for the LY7? Would they fit? Would they be...
