Holden Problems

By 'rides' I’ll assume you mean 'slips', which then slowly allows the car to build up to speed (as in, the rest of the car catches up with the engine). There are two major causes of this, the first is a clutch that is out of adjustment, and the second is a clutch that really needs replacement.

The problem you have, though, is that even if the clutch on the Barina is adjustable (and some clutches aren’t) the fact that you’ve been driving it with the clutch slipping suggests that you’ve already damaged the clutch to the point where it would need to be replaced anyway. Continuing to drive it can also put 'hot-spots' on the car’s flywheel (to which the clutch attaches) and that can mean the flywheel also needs to be resurfaced when you replace the clutch.

I reckon, at the minimum, you’re looking at a new clutch kit. Ignoring it will eventually wind up with the clutch expiring completely and you walking home.

The first response of most mechanics on this would be that you have a head gasket leak in the engine. Coolant in the oil and/or oil in the coolant are classic symptoms of this. It happens because the faulty head gasket allows the two fluids to mix but, depending on exactly where the gasket fails, you don’t necessary get both symptoms. A workshop can pressure test the engine’s cooling system and perform what’s called a TK test to show up any contaminants in the coolant that have found their way there via a blown head gasket.

But before you go tearing into the engine, check the service records to find out how old the coolant is. Coolant will discolour over time and kilometres and what you’re seeing as a `milky colour’ might simply be old coolant that has gone cloudy and needs changing.

Depending on what sounds the engine is making will determine whether the engine is a throwaway or can be fixed. But if the consensus is that the engine in your car is beyond redemption, then I reckon a second-hand engine from a wrecked Captiva would be the best bet. I don’t think the car itself would be worth enough money to justify a rebuilt engine which could run to $10,000 or more.

Nobody wants to tell you this, but fundamentally, the Captiva was a pretty ordinary car. Lots of owners had lots of transmission problems (which you already know about) and plenty of diesel engines destroyed their turbochargers and – in some cases – the rest of the engine in the process. The petrol V6 was no beacon of excellence either, with a terrifying propensity to consume timing chains.

Who at Holden has rejected your claim for help in repairing the car? If it was the dealer, I’d simply go around that business and talk directly to Holden’s customer service department. The fact that the car has a full Holden service history might sway opinion at head office, but I wouldn’t be going to the bank on it given the age of the vehicle.

It all depends on what engine is fitted to your car, Karen, as Holden used a range of gearboxes in this series of Commodores. If your car is the base-model version (the Omega) it will be fitted with a four-speed automatic (code-named the 4L60E). If your car is an SV6, it will have either a five-speed automatic (5L40E) or a six-speed manual (the Aisin D173/AY6 unit). If your car is a V8 Commodore, it will have either the six-speed automatic (6L80) or a six-speed manual (Tremec T56) fitted.

Of all those transmission options, the five-speed automatic was the odd one out as it was only used from the launch of the VE until the first facelift in 2008 when it was replaced by a six-speed automatic.

The prime suspect for this is a blocked vent that normally funnels condensation from the air-conditioning system to the outside of the car. If this vent becomes blocked or split, the condensation can enter the cabin. Other possibilities include a damaged heater matrix which can leak coolant into the cabin or a sunroof with blocked drainage channels that can also leak into the vehicle.

It’s quite possible for a car’s engine to lose a little performance over time as it wears internally. When that wear occurs, the compression ratio can fall a little, the valve timing may alter a fraction and the fuel injection system might get a bit slack. All these things can lead to a slight drop off in power. Because this dwindling power output happens gradually, most owners never notice it happening.

But since the Holden Combo was a fairly low-powered car to start with, there could be some external factors that are making it feel a little tardy at times. Again, since you’re not playing with a whole lot of power in the first place (a Combo had just 66kW when it was brand-new) even tyres that have deflated over time (perfectly normal) can make the car feel a bit slower from time to time. The same goes for a brake that is dragging slightly or even having a second occupant or a heavier than usual load in the car. Even a decent headwind can make a Combo feel like it’s struggling.

The best idea in the long term is to service the vehicle properly and make sure it’s in top condition. That will rule out some of those external factors and will keep the thing in good mechanical condition so that it can muster up the maximum number of kiloWatts when you need them. You could also try a bottle of injector cleaner in the fuel tank now and then, and don’t forget the basics like a blocked air-filter, and old, stale fuel which can also rob power.

Excess black smoke from a diesel engine is bad news as it can – among other things – cause the engine to run hot enough to cause internal damage. As for a cause, it could be anything from contaminated fuel to a block air-filter, a faulty sensor or a damaged intake system. Modern diesel engines like this one also have a habit of forming black deposits in their intake tract (a by-product of the engine’s own emission controls) and this can cause all sorts of problems including black smoke.

Another possibility is that the car’s diesel particulate filter (DPF) is blocked and the car is trying to regenerate it (clean it out) by dumping lots of fuel into the engine, and that’s causing the excess smoke. Either way, it needs to be fixed to avoid the potential for costly engine damage, not to mention the environmental havoc the car is causing in its current state. An electronic scan of the onboard computer would be a good starting point.

To connect your mobile phone to the Holden Cruze’s optional Bluetooth system for hands-free phone operation, the first step is to check your phone settings to ensure that Bluetooth is enabled and that the phone is `visible’ or `discoverable’.

From the info-screen in the car, select Add Device (Handsfree) at which point the car’s Bluetooth system will search for and find the signal from your mobile phone. When that happens, a four-digit code should be displayed on the screen which is then keyed into the phone’s keypad to make the connection. The car will then ask you if you want to pair your phone and you press `Yes’ to complete the pairing process.

As many as five mobile phones can be connected to the Holden Cruze Bluetooth system. You can then choose a different phone to pair by choosing one from the device list displayed on the info-screen. Once the connection is established, you can operate many of the phone’s functions through the car’s information screen including your address book and adjusting the volume of the phone call.

For more instructions on how to play music through the system, more setup options, and troubleshooting problems, refer to the vehicle’s owner’s manual.

The V6 engine in the Captiva is well known for its propensity to suffer from worn or stretched timing chains far too early in life. Early signs can be a rattling noise when the engine is first started (hot or cold) as well as a check-engine light on the dashboard. The check-engine light is a result of the stretched chain allowing the camshafts to move so far out of sync with the rest of the engine that the sensor that measures their position can longer 'find' them. At which point, the warning light is triggered.

You can also have the car electronically scanned to see what’s going on. If the computer throws up fault codes P0008, P0009, P0016, P0017, P0018 or P0019, then you almost certainly have a stretched timing chain. Replacement of the chain is the only proper fix.

On the lower-right corner of the dashboard, you’ll find the rotary switch that controls the headlights. On the same switch panel (just to the left of the main headlight switch) are a pair of sliding controls that control the headlight aiming (the right-hand slide) and the dashboard-light brightness (just to its left).

When the car’s headlights are turned on, the dashboard lights are automatically dimmed, and sometimes this provides insufficient light to see the gauges clearly in bright daylight. But by holding the adjustment slide in the up position, you can turn the dashboard lights to their brightest level of illumination.
