There is something particularly satisfying about seeing a well kept Holden Commodore ute still doing exactly what it was designed to do. While Holden may no longer manufacture vehicles in Australia, there are still plenty of Commodores travelling around Nambour and the wider Sunshine Coast every day, and many of them have years of useful life ahead of them when they are maintained properly.
This bright red 2010 Holden Commodore is a great example. It came into Power Curve Automotive for a general service, and rather than treating the appointment as simply an oil and filter change, we worked through our normal service and inspection process to get a much broader picture of the vehicle’s condition.
Overall, the Commodore presented well. There were plenty of areas that passed inspection and didn’t require unnecessary work, but we also identified a couple of fluids that needed attention, tyre pressures that required correcting and some future maintenance that should be planned.
That distinction is important to us.
A good vehicle service shouldn’t be about finding as many things as possible to sell to the customer. It should establish what is in good condition, what needs attention now and what is likely to need attention in the future. That gives the owner useful information and allows maintenance to be planned rather than waiting until something becomes a breakdown or a much larger repair.
For older vehicles such as this Commodore, that approach can make a significant difference to how confidently and economically they can be kept on the road.
Holden Servicing Is More Than an Oil Change
When people talk about having their car serviced, the first thing that usually comes to mind is replacing the engine oil and oil filter. Those are certainly important parts of routine maintenance, but they are only a small part of what we want to achieve when a vehicle comes into Power Curve Automotive.
We want to understand how the vehicle is actually travelling.
Where appropriate and safe to do so, that process starts with a test drive. A technician can learn a considerable amount about a vehicle before it even enters the workshop. Steering feel, braking behaviour, unusual vibrations, suspension noises, transmission operation and general engine performance can all provide information that isn’t necessarily visible when a vehicle is sitting stationary on a hoist.
Once back in the workshop, we work systematically through the vehicle. Under the bonnet, underneath the vehicle, through the braking and suspension systems and across the tyres, fluids and other serviceable components, we’re looking at the vehicle as a complete package.
On this 2010 Commodore, the inspection showed a vehicle that had quite a few positives. The aim then became maintaining those good areas while addressing the items that were beginning to require attention.
Starting Under the Bonnet
The engine bay inspection involves considerably more than removing the old oil filter.
We checked the vehicle’s fluids, lights, horn and wipers and used our diagnostic equipment to check the electronic systems for relevant fault information. Depending on the vehicle and the work approved, our servicing process can also include cleaning components such as the throttle body and mass airflow sensor, lubricating doors and hinges, adding an injection cleaner and checking the washer system.
These small checks individually may not sound particularly significant, but together they contribute to maintaining a vehicle properly.
The condition and levels of fluids can tell us a lot about what has been happening between services. A fluid that has unexpectedly dropped in level, changed condition or become contaminated may be an early indication that something needs further investigation. Catching that information during routine servicing gives us an opportunity to investigate before a customer is dealing with a more serious problem.
In this case, the engine bay fluids were checked and the coolant passed our inspection.
Cooling System Checked and Coolant Passed
Cooling system condition is particularly important on an ageing vehicle, and Queensland conditions don’t make life particularly easy for cooling systems.
Our warm climate, highway driving and stop, start traffic can all place additional demand on the system. If a vehicle is allowed to overheat severely, the consequences can extend well beyond simply replacing a radiator or hose, which is why cooling system maintenance is something we take seriously.
During this Commodore’s service, the coolant quality and level were checked and passed inspection. That is good news, and it’s exactly the kind of result we want to be able to give a customer.
Not everything inspected during a service needs to result in a recommendation.
Recording that something has passed is valuable because it establishes its current condition and gives us something to compare against at future services. If the coolant level begins dropping, its condition changes or another issue develops later, there is already some service history behind the vehicle.
Engine Oil and Filter Replacement
The engine oil and oil filter were replaced as part of this service.
Engine oil has an enormous amount of work to do. It lubricates internal components, assists with temperature management, carries contaminants toward the filter and helps protect internal engine surfaces. As the oil accumulates kilometres and goes through repeated heating and cooling cycles, its ability to perform those jobs gradually deteriorates.
The filter has an equally important role because it captures contamination circulating with the oil. Replacing fresh oil while leaving an old filter in place would compromise the purpose of the service, which is why the two are replaced together at the appropriate service interval.
Regular oil servicing becomes particularly important as vehicles get older. An older engine doesn’t necessarily mean an unreliable engine, but maintaining lubrication and monitoring for leaks or changes in oil consumption becomes increasingly important as kilometres and years accumulate.
This is also why we generally recommend maintaining a regular service routine rather than stretching intervals simply because the vehicle appears to be running well. Preventative maintenance is designed to help keep it running well.
The Air Filter and Air Box
The engine air filter was inspected and passed, and the air box was cleaned.
Again, because the filter passed, it didn’t need to be unnecessarily replaced.
The air filter’s job is to allow the engine to receive the airflow it needs while preventing dirt and debris from entering the intake system. Sunshine Coast driving can expose vehicles to everything from ordinary road dust to significantly dirtier conditions depending on where and how they’re used.
An excessively contaminated filter can restrict airflow, while problems within the intake system can potentially allow contamination where it shouldn’t be.
Checking the filter during servicing gives us the opportunity to assess its actual condition. In this Commodore it remained serviceable, so it could stay in the vehicle.
That might seem like a small point, but it represents an important part of how we approach maintenance at Power Curve Automotive: test and inspect first, then replace what actually requires replacement.
Battery Tested — Pass
The Commodore’s battery was also tested and passed.
A vehicle can start normally today while the battery is already deteriorating internally, which is why we prefer testing over simply looking at a battery and assuming everything is fine.
Battery testing gives us much more useful information about its current ability to perform. When a battery passes, as this one did, we can report that back to the owner rather than recommending replacement based purely on age or guesswork.
It also gives us a baseline for future servicing.
If the battery’s performance starts declining at a later service, the owner has an opportunity to plan a replacement before reaching the frustrating stage where the vehicle suddenly won’t start one morning.
For this visit, however, the battery received a pass and no replacement was required.
Brake Fluid Failed Our Test
One area that did require attention was the brake fluid.
Brake fluid is often overlooked because there may be no obvious visual sign from outside the vehicle that its condition has deteriorated. The reservoir can be full and the brakes can still appear to operate normally, but that doesn’t necessarily tell us whether the fluid itself remains in suitable condition.
Brake fluid is hygroscopic, meaning it absorbs moisture over time. As its moisture content increases, its performance characteristics deteriorate and its boiling point is reduced. Under demanding braking conditions, maintaining the correct fluid condition becomes particularly important.
Rather than relying solely on time or appearance, we tested the brake fluid during the service. The reading showed 3.3%, which failed our inspection criteria and indicated that the fluid was due for replacement.
With the customer’s approval, we carried out a brake fluid flush.
This removes the aged fluid and replaces it with fresh brake fluid through the system, restoring an important maintenance item rather than simply topping up what is already there.
It is a good example of why we test fluids during servicing. Without the test, the reservoir could simply have been looked at and marked as full. Testing gives us more meaningful information.
Inspecting the Brakes Themselves
While the brake fluid required attention, the physical brake components still had usable life remaining.
The front brakes passed inspection at approximately 50% worn, while the rear brakes passed at approximately 40% worn. The rear brakes were also cleaned and the handbrake was adjusted as part of the service.
This is another area where reporting percentages can help owners plan future maintenance.
If we simply say “brakes are okay”, that doesn’t provide much information. Knowing approximately how much wear is present gives the customer a better understanding of where things currently stand. It also allows us to monitor the rate of wear at future services.
Driving style, vehicle use and kilometres travelled can all affect how quickly brakes wear, so we don’t automatically turn a wear percentage into an exact replacement date. Instead, it becomes part of the vehicle’s ongoing maintenance picture.
At this stage, the Commodore’s brakes passed.
Rear Differential Oil Required Replacement
Further underneath the vehicle, the transmission and drivetrain fluids were inspected.
The transmission fluid passed the inspection at this service, although an automatic transmission flush and filter service is due according to the vehicle’s logbook and has been noted for rebooking.
The rear differential oil, however, failed our inspection and was replaced during this visit.
Differential oil works in a harsh environment. Inside the differential, gears and bearings operate under considerable load, and the lubricant must protect those components while dealing with heat and contamination over a long service period.
Because the differential is generally quiet and hidden underneath the vehicle, its oil can be easy to forget. There isn’t a dashboard warning appearing every time the fluid ages.
That doesn’t make it unimportant.
Replacing the differential oil when required is relatively straightforward preventative maintenance compared with repairing internal differential damage caused by inadequate lubrication or severely deteriorated oil.
For this Commodore, replacing the rear differential oil meant another overdue maintenance item could be brought back up to date.
Tyres: From 24 PSI to 32 PSI
The tyres also gave us something worth correcting.
When the Commodore arrived, the tyres were sitting at approximately 24psi. They were adjusted to 32psi as part of the service.
Tyre pressure affects much more than whether a tyre looks flat. Incorrect pressures can influence tyre wear, steering response, braking, fuel consumption and how the vehicle behaves on the road.
Because pressure naturally changes over time, it shouldn’t be something that is checked only when a tyre visibly appears low.
We also assessed tyre wear. The front tyres passed inspection at approximately 55% worn, while the rear tyres passed at approximately 40% worn.
Again, neither required immediate replacement, but recording the wear gives the owner useful information and allows it to be monitored.
But There Was One Tyre We Wouldn’t Ignore
The spare tyre presented a different concern.
It is 16 years old.
Even if an old spare still has plenty of tread and hasn’t spent its life rolling along the road, tyre age still matters. Rubber compounds deteriorate with time and exposure, and a spare tyre spends years subjected to temperature changes and environmental conditions even while it isn’t being used.
The problem with an ageing spare is often discovered at exactly the wrong moment.
If you get a puncture on the side of the road, the spare suddenly goes from being something that has sat unnoticed for years to something you’re relying on to safely carry the vehicle.
For that reason, we have recommended replacing the 16 year old spare.
It doesn’t mean replacing all of the tyres unnecessarily. The tyres currently fitted to the vehicle passed their inspection. The recommendation relates specifically to the condition and age of the spare.
Suspension Inspection — Pass
With the Commodore on the hoist, the suspension components were inspected and greased where applicable.
The suspension passed.
Suspension inspections become increasingly valuable as a vehicle ages because bushes, ball joints, shock absorbers and other moving components gradually wear. That wear doesn’t always happen suddenly. In many cases it develops slowly enough that the driver becomes accustomed to a change in handling or a new noise without realising how different the vehicle feels compared with when everything was in better condition.
Putting the vehicle on a hoist gives our technicians an opportunity to physically inspect those components and look for movement, deterioration, leaks and other signs of wear.
In this case, there wasn’t a suspension repair we needed to sell the customer. It passed, so we recorded it as such.
Automatic Transmission Service to Plan Next
While the transmission fluid passed its current inspection, the automatic transmission flush and filter is due according to the logbook.
We’ve therefore recorded this as a rebooking item.
This is where we believe good communication can make vehicle ownership considerably easier.
Not every maintenance item needs to be completed on the same day. If something isn’t currently unsafe or requiring immediate attention, giving the owner advance notice allows them to plan the work around their schedule and budget.
Transmission maintenance is something we don’t recommend forgetting simply because the transmission currently feels normal. Automatic transmissions rely heavily on their fluid for lubrication, hydraulic operation, cooling and internal component protection.
Waiting for a transmission to start displaying symptoms before considering maintenance can mean waiting too long.
By identifying the upcoming service requirement now, it can be booked and dealt with as planned maintenance.
What We Completed on This Holden Commodore
By the time this 2010 Commodore left Power Curve Automotive, the service had included the vehicle inspection, adjustments, lubrication and report, along with replacement of the engine oil and oil filter.
The failed brake-fluid test had been acted upon with a brake fluid flush, and the rear differential oil had been replaced after its condition failed our inspection.
The tyre pressures had been corrected, the rear brakes cleaned and handbrake adjusted, and the air box had been cleaned while the air filter itself passed inspection.
Just as importantly, we had established that a considerable number of areas didn’t require repairs.
The battery passed, coolant passed, engine air filter passed, suspension passed, brakes retained usable life, transmission and transfer case fluid passed their current inspection.
That information matters.
Keeping Older Holdens Rather Than Automatically Replacing Them
There can be a tendency to assume that once a vehicle reaches a certain age, spending money on maintenance no longer makes sense.
We don’t believe vehicle ownership is quite that simple.
A well maintained older vehicle that suits its owner’s needs can still be an extremely useful vehicle. The owner knows its history, knows how it has been treated and, with regular inspection, can make informed decisions about what is worth maintaining and what needs to be planned for.
That doesn’t mean every old vehicle should be repaired indefinitely regardless of cost. There will always be situations where the overall condition of a vehicle means a customer needs to consider whether further repairs make financial sense.
The important thing is having enough information to make that decision properly.
A 2010 Commodore that has been maintained, presents well and continues to pass its major inspections is very different from a neglected vehicle of exactly the same age.
Age is only one part of the story.
Why Preventative Maintenance Matters
One of the biggest advantages of routine servicing is the opportunity to identify changes while they are still manageable.
The brake fluid in this vehicle is a perfect example. There was no need to wait until the owner complained about braking performance. We tested the fluid, identified that its condition had deteriorated and replaced it.
The same principle applies to differential oil, tyres, batteries, suspension components, cooling systems and many other parts of a vehicle.
Preventative maintenance isn’t about replacing everything early.
It is about inspecting properly, measuring where possible and using that information to make sensible maintenance decisions.
Sometimes that means replacing something today. Sometimes it means noting something for the next service. And sometimes it means telling the customer that a component has passed and doesn’t need anything.
All three outcomes are part of proper vehicle servicing.
A Service Report Should Help You Understand Your Car
Transparency is a major part of how we approach servicing at Power Curve Automotive.
We want customers to understand what we’ve looked at and why we’re making a recommendation.
If a fluid fails a condition test, we can show that. If a filter is still serviceable, we can report that it passed. If a component is beginning to wear but doesn’t require immediate replacement, we can explain what we’ve found and continue monitoring it.
That creates a maintenance history rather than a series of disconnected workshop visits. Over time, it also makes it easier to spot changes.
If brake wear has progressed considerably between services, we know it needs closer attention. If a battery that previously tested strongly begins declining, we can discuss replacement before it leaves the customer stranded. If a fluid condition changes unexpectedly, we can investigate why.
Good servicing is as much about gathering information as it is about replacing parts.
Holden Mechanic on the Sunshine Coast
Although Holden is no longer manufacturing new vehicles in Australia, that certainly doesn’t mean existing Holdens have disappeared from our roads.
Commodores, Colorado utes, Captivas, Astras, Cruzes and other Holden models remain part of the everyday vehicle population around Nambour, Maroochydore and the wider Sunshine Coast.
As these vehicles age, the quality of ongoing maintenance becomes increasingly important.
At Power Curve Automotive, our servicing approach isn’t based on rushing a vehicle through for an oil change. We inspect the vehicle, test what can be tested, communicate what we find and help the owner distinguish between maintenance that is required now and maintenance that can be planned.
For this particular 2010 Holden Commodore ute, the result was reassuring.
It wasn’t a service that uncovered a huge list of repairs. Instead, it showed us a vehicle with a number of systems in good condition, two fluids that required attention, tyre pressures that needed correcting, an ageing spare tyre and an upcoming transmission service to plan.
That’s useful information for the owner.
And with the engine oil and filter replaced, brake fluid flushed, differential oil replaced and the rest of the vehicle inspected, the ute can head back onto Sunshine Coast roads with its maintenance brought another step forward.
Holden Servicing in Nambour
If you own a Holden, the fact that the badge is no longer attached to new Australian built vehicles doesn’t mean your current vehicle suddenly needs to be retired. For many owners, maintaining the vehicle they already know and enjoy can make a lot of sense. The key is knowing what condition it is actually in.
At Power Curve Automotive in Nambour, we service and repair Holden vehicles from across the Sunshine Coast, with an emphasis on thorough inspections, preventative maintenance and clear communication.
Our aim is simple: inspect the vehicle properly, show you what we find, explain what it means and help you make an informed decision about what your vehicle needs.
For this bright red Commodore ute, that meant replacing what was due, leaving alone what was still in good condition and planning ahead for the next maintenance items. Because keeping an older Holden on the road isn’t about replacing parts for the sake of it.
It’s about looking after the right things at the right time.
