Mechanic in Smithfield
The junction the whole northern corridor passes through. Highway kilometres are kind to a car in most ways, and there are two where they are not.
Highway kilometres are the good kind, mostly
Smithfield sits where the Captain Cook Highway meets the road up the range, and it is the junction almost every northern beaches vehicle passes through. It is also a university suburb, which puts a lot of older, cheaper cars into the mix alongside the family vehicles.
Cars here do more highway running than cars in the inner suburbs, and that is genuinely good for them. Sustained speed means the engine reaches and holds operating temperature, oil circulates properly, moisture gets driven out of the exhaust and the crankcase, and a diesel’s particulate filter gets the heat it needs to clear itself. Almost every problem the short-trip suburbs have, this one does not.
There are two places where highway kilometres are harder, and both are worth knowing.
The first is that the odometer climbs
Time-based intervals catch out low-kilometre cars. Kilometre-based intervals catch out this lot. A Smithfield car can reach a major service interval in half the time an inner-city car takes, and the items that fall due at those bigger intervals are the ones people are least prepared for: transmission services, coolant, spark plugs, and on a belt-driven engine, the timing belt.
None of that is a problem if it is expected. It becomes one when a car quietly passes an interval nobody was tracking. If you are doing serious kilometres, the useful thing is knowing what is coming at the next two services rather than only the next one, so it can be budgeted rather than absorbed.
The other consequence is tyres and suspension. Highway kilometres wear tyres evenly and steadily, and they work shock absorbers continuously. Shock absorbers rarely fail suddenly; they fade, and because it happens gradually the driver adapts without noticing. On a high-kilometre car it is worth having them assessed deliberately rather than waiting for an inspection to fail one.
The second is heat with the air conditioning working
Highway running in this climate means the air conditioning is on, at full load, for the whole trip, every day.
Car air conditioning here does more work than almost anywhere in the country, and the condenser, which is the radiator-looking part right at the front of the car, is directly in the path of everything the highway throws at it: insects, grit, road film and salt off the coast road. It corrodes from the front and it blocks.
The pattern that produces is recognisable. The system is cold when moving and less cold in traffic, because at speed there is enough airflow to work despite the blockage, and in a queue there is not. If that describes yours, the fault is usually the condenser or a cooling fan rather than the gas. There is more on that on the car air conditioning page.
Student cars
Worth a mention because there are a lot of them here: cheap, older, often bought quickly and sold again in a year or two.
For a car like that the sensible spend is on the things that will strand you or fail an inspection, and not much else. Cooling system, battery and charging, brakes, tyres, and any structural rust. If you are buying one, an hour on a hoist beforehand is the best money in this whole business, because the difference between a tidy old car and a money pit is almost entirely invisible from the outside.
Book a car in from Smithfield
Make, model, year and roughly the kilometres, plus what the car is doing and when it does it. That is enough to give you a real number and a slot rather than a range.
- Workshop hours
- Monday to Friday, 7:30am to 5pm
- We cover
- Cairns, the southern corridor to Gordonvale, and north to Trinity Beach
- Vehicles
- All makes, petrol and diesel, including 4WDs and work utes
- Send the make, model, year and roughly what the odometer reads. Half of what decides a price is which service interval the car is up to, and none of that is guessable from the model alone.
- Say what the car is doing and when it does it. A noise that only turns up cold is a different fault from one that only turns up hot, and that single detail regularly saves an hour on the hoist.
- The number you approve is the number you pay. If the job turns out bigger once it is apart, the work stops and you get a call, rather than a larger invoice at the end.
