Logbook Servicing
Whenever you purchase a new vehicle, the manufacturer provides you with a warranty that covers the cost of parts failures. This warranty is only valid, however, if you have your vehicle regularly serviced by a certified mechanic, who records and stamps these services in your vehicle’s logbook.
Here at Gavan Johnson Mechanical, our mechanics are fully certified to provide logbook services for all:
- Petrol vehicles
- Diesel vehicles
- LPG vehicles
- Electric/hybrid vehicles
Vehicle Inspections
Whenever you’re planning on selling or otherwise transferring ownership of a vehicle, you are first legally required to obtain a Safety Certificate. Issued by a licensed tester after an exhaustive inspection, Safety Certificates ensure that your vehicle meets the minimum safety standards to be driven on Queensland roads.
We would recommend a pre-purchase inspection when you’re looking at buying a secondhand vehicle. The pre-purchase inspection is a thorough check of the entire vehicle, ensuring that you know exactly what you’re buying, and avoid any nasty surprises. Here at Gavan Johnson Mechanical, we can even provide you with an estimated cost of repairs for you to factor into your buying decision.
Brake Services
Your brakes are the most important safety feature your vehicle has. Unlike other safety systems, your brakes can act preventatively, and the condition of your brakes is often the deciding factor between an accident and an emergency stop.
Your brakes suffer a surprising amount of wear, after all, they routinely bring over a tonne of metal to a complete stop multiple times a day! For this reason, we agree with brake manufacturers that you should have your brakes checked at least once a year.
Gavan Johnson Mechanical’s expert mechanics are fully equipped to help you with:
- Brake component machining
- Brake component replacement
- Brake hose repairs
Steering & Suspension
Faults and flaws in your vehicle’s steering and suspension affect handling and ride comfort, causing play in the steering wheel and body lean through corners. Your suspension is also responsible for maximising the grip that your tyres exert on the road surface, so a poor suspension will increase your stopping distance.
Here at Gavan Johnson Mechanical we can help you with:
- Shock absorbers, springs and struts
- Bushing replacement
- Power steering repairs and replacement
- Lift kits and 4WD upgrades
Air Conditioning 
Nothing ruins a summer drive faster than broken air conditioning. Your air conditioning is interesting in that it degrades more from disuse than use, as the rubber tubing and seals dry up and crack, allowing the refrigerant gas to leak out and rob your aircon of its cooling power.
Here at Gavan Johnson Mechanical we can fully repair your air conditioning, replacing faulty compressors and condensers, swapping out cracked tubing, and finally re-gassing your system with refrigerant once we’re certain it’s airtight.
Clutch & Transmission
As part of the assemblage that transfers power from the engine to the wheels, your clutch and transmission are made up of some of the most sophisticated and intricate machinery in your vehicle. Due to their complex nature, even minor flaws can quickly proliferate into very costly repairs.
If you are having trouble changing gears, or you notice a grinding noise when you do so, or a burning smell coming from under the bonnet after a drive, you may have a problem with your clutch or transmission.
Gavan Johnson Mechanical can help you with:
- Clutch repairs
- Automatic and manual transmission repairs and servicing
Diagnostics & Auto Electrical
As modern vehicles have increased in complexity, more functionality is being governed by the auto electrical network. The network handles everything from playing music and monitoring fuel consumption to assisting with braking and gear changes, even monitoring your engine and putting your vehicle into limp mode if a serious flaw is detected, to prevent any permanent damage.
Here at Gavan Johnson Mechanical, our expert auto electricians can help you with:
- Full diagnostics
- Battery test and replacement
- Alternators and starter motors
- Component test and replacement
- Audio installations
- Lighting upgrades
- Accessory installation
- Solar/battery systems
Cooling systems
If your cooling system is malfunctioning, it can cause myriad problems, from reduced fuel efficiency and engine output, to reduced engine lifespan as overheating and leaking coolant damages the engine components. If these problems are ignored for long enough, they will render your vehicle immobile, with the cost of repairs being comparable to buying a secondhand car!
Gavan Johnson Mechanical’s skilled mechanics can provide the following cooling system repairs:
- Radiator/heater unit repairs and replacement
- Head gasket replacement
- Coolant flush and leak check
- Thermostat check and replacement
Tyres & Wheels
While they might seem simple at first, your tyres are actually complex pieces of equipment, and the condition of your tyres is the deciding factor in how much grip you exert on the road surface, especially during wet weather, where the treads of the tyres act as channels to divert the water away from where the contact patches meet the road.
Tyre manufacturers design their products with built-in redundancies which allow them to provide acceptable grip even as they wear. These designs are useless however, if your wheels are misaligned or unbalanced, as this causes uneven wear the manufacturers could not account for.
Gavan Johnson Mechanical’s expert staff can help you with:
- Wheel alignment
- Tyre balancing
- Tyres from major brands for all makes and models of
- Car
- 4WD
