If your Commodore or Falcon has started running hot every time you’re stuck in traffic on the Kwinana Freeway or crawling through peak hour on Great Eastern Highway, you’re not alone. These two models were on Perth roads in huge numbers for two decades, and a lot of them are now well past 200,000 kilometres. Overheating is often one of the first serious problems to show up as they age – and it’s also one of the clearest signals that it might be time to weigh up what another repair will cost against what the car is actually worth.
Why Commodores and Falcons Start Overheating as They Age
There’s rarely just one cause. In older Commodores and Falcons, overheating usually comes down to a handful of wear-and-tear issues that tend to compound each other:
- Radiator core corrosion – internal build-up restricts coolant flow, especially in cars that have never had a coolant flush.
- Water pump wear – a common failure point on high-km six-cylinder and V8 engines alike.
- Head gasket failure – more common on older six-cylinder Commodores and Falcons that have overheated once already, since a gasket that’s been cooked once rarely seals properly again.
- Sticking thermostats and perished hoses – cheap parts individually, but they add up when several fail around the same time.
- Blocked airflow through the radiator or A/C condenser – road grime and insect debris reduce cooling efficiency, which shows up more in Perth’s summer heat than anywhere else.
On their own, most of these are straightforward repairs. The problem is that on an older car they rarely happen in isolation.
When Repairs Stop Making Sense
There’s no fixed rule for when to stop fixing an old car, but there are a few patterns worth paying attention to.
Signs it might be time to stop repairing
- The overheating keeps coming back after a repair, suggesting the underlying cause hasn’t actually been fixed.
- The repair quote is getting close to, or higher than, what the car would sell for.
- Several ageing systems are failing around the same time – cooling, transmission, suspension – rather than one isolated fault.
- You’ve stopped trusting the car on longer drives and it’s mostly sitting in the driveway.
A head gasket job or radiator replacement on a Commodore or Falcon that’s otherwise tired isn’t always a bad decision, but it’s worth getting an honest quote and an honest look at the car’s overall condition before committing to it.
What Actually Affects What an Old Commodore or Falcon Is Worth
A car doesn’t need to be roadworthy to have value. What it’s worth as a sale to a wrecker or removal service depends more on these factors than most people expect:
- Whether it runs or not – a non-runner still has value in its engine, transmission, panels, and other reusable parts.
- Variant and engine – V6 vs V8, sedan vs wagon vs ute, and how in-demand those parts still are.
- Completeness – a car that’s missing an engine, gearbox, or major panels is worth less than one that’s intact, even if neither runs.
- Damage type – overheating damage, accident damage, and rust are all assessed differently.
- Registration status – the car doesn’t need to be currently registered to be sold.
Selling a Damaged or Non-Running Car in WA – What to Know
There are a few WA-specific things worth knowing before you sell an old Commodore or Falcon, whether it’s running, overheating, or written off:
- Number plates stay with you, not the car. They don’t transfer to the buyer.
- After the sale, you’ll need to lodge a Notification of Disposal with the WA Department of Transport to formally take the car off your name.
- You’ll need valid photo ID to sell the car – you don’t have to be the registered owner, but you do need to be able to identify yourself.
- Vehicles that are stolen, still under finance, or are simply a body without a chassis generally can’t be bought or sold this way.
Deregistered vehicles, written-offs, and cars with accident, flood, or fire damage can all still be sold – overheating damage included.
How the Process Works with Cash For Cars Perth
Cash For Cars Perth buys Commodores, Falcons, and most other cars, utes, trucks, vans, and 4WDs across the Perth metro area, in any condition, running or not – up to $9,999 depending on the vehicle. The yard is based at 5 Hantke Place, Welshpool, a licensed facility that dismantles and recycles vehicles rather than sending them straight to landfill.
The process is generally quick: a quote over the phone, free same-day towing (often within two to three hours if you call before midday), and payment in cash or instant OSKO transfer before the car leaves your property. Note that the service covers Perth metro only – it doesn’t extend to Bunbury or further south.
Deciding What’s Right for Your Car
If your Commodore or Falcon is overheating for the second or third time, it’s worth being honest about whether you’re fixing the car or just delaying the next breakdown. Sometimes another repair genuinely makes sense. Other times, selling it as-is – overheating, non-running, or otherwise – saves you the cost, the hassle, and the uncertainty of the next repair bill.
If you’d like an idea of what your car is worth in its current condition, call Cash For Cars Perth on 0420 262 651 (open Monday to Saturday, 7:30 AM to 6:00 PM) or get a quote online. There’s no obligation to sell, and no need to fix anything first.
