Component lifespans
This list can’t possibly be completely accurate due to environmental conditions of each cars life. Estimates are based on cross-referencing of various sources, and you should ALWAYS verify if a part needs to be replaced before replacing if at all possible.
This list complements the factory maintenance schedules table, which is more rooted in factory specification when the AU Falcon was new
please refer to the table below for expected lifespans of various components, along with notes regarding failure and lifespan:
| Part Name | lifespan | Notes |
|---|---|---|
| ABS Speed Sensors | 200,000km | check and replace if triggering when braking with slight steering at slow speed |
| Alternator | 250,000km | assuming no leaks from power steering, check for battery light on dash or running voltage less than 13v |
| Battery | 5 years | voltage should read 12.3-13v while car is off and 13.5-15v while car is running in idle |
| Ignition Coil Pack | 150,000km | Ignition Coil can be tested for resistance, known failures below 9KΩ secondary resistance |
| Intake Manifold Gaskets | 200,000kms | Vehicles prone to an increased amount of cold-starts appear to breakdown earlier |
| Oil filter | 20,000km | assuming still using rated 5w30. Thicker oils can be used as car ages if increased “lifter tick” is observed |
| Power Steering High Pressure Line | 100,000km | can be made significantly longer by getting redesigned aftermarket line without gap between nut and line |
| Spark plugs (copper) | 20,000km | more likely to start phantom misfiring at idle as they start to fail |
| Spark plugs (iridium) | 75,000km | generally worth extra cost vs. Copper |
| Steering Rack | 150,000km | look out for popping noise when nearing full lock |
| Thermostat | 100,000km | can fail open (temp. constantly on C using more fuel) or fail closed (quick to overheat). Can be easily extended by using coolant rather than water for the cooling system |
