Auto Electrical

Smithfield Car Diagnostics is equipped with scan tools and diagnostic machines to quickly identify any auto electrical faults. Our skilled technicians can then resolve the problem for you promptly and efficiently. Our auto electrical servicing includes repairs or replacements for alternators, starter motors and ignitions.

We can also maintain:

  • Electronic fuel pumps
  • Automatic transmissions

  • Electric mirrors
  • Audio and camera systems

We provide auto electrical servicing for all car makes and models, including 4WDs.


All-wheel drive and 4WD vehicles rely on computer-controlled driveline systems to ensure safe and smooth handling of all wheels. At Smithfield Car Diagnostics, we provide servicing and repairs of the drive line systems for most makes and models. We specialise in the repair and maintenance of CV joints, transfer cases, differentials and fluid components.

When necessary, we will drain and replace the fluids with the highest quality lubricants available. Our technicians can also fit replacement parts should this be required.

Cooling Systems

An efficient cooling system not only draws the heat away from the engine, it also reduces wear and tear on its components. If you are experiencing leaking coolant or a rapidly climbing temperature gauge, visit the team at Smithfield Car Diagnostics. Our technicians can perform a visual inspection and a radiator flush to identify any leaks or blockages.

We will check the hoses and water pump for leaks, inspect the seals and coolant levels then pressure test the radiator. Should there be any signs of leaking or damage, we can swiftly repair this for you.

Engine Repairs

At Smithfield Car Diagnostics, we work on cars of all ages, makes and models. This includes engine repairs and restorations for older vehicles. Our qualified Smithfield mechanics can provide minor and major engine repairs, supply and fit exchange engines or completely rebuild an existing engine.

A reconditioned engine can provide premium engine performance and improved fuel economy for your vehicle. Of course, all exchange engines and reconditioned engines are guaranteed for quality and performance.

Speak to our qualified mechanical staff about your engine repairs or requirements for more information.

Fuel System - EFI

A build-up of carbon, dirt and general grime in the fuel system can reduce the performance of your vehicle.

Our fuel system servicing includes:

  • Full engine tune-up
  • Fuel injector cleaning
  • Inspection of fuel lines and air intake system
  • Electronic fuel pump inspection

Suspension & Steering

At Smithfield Car Diagnostics, our technicians are experts in the maintenance and repair of car suspension and steering systems, including those for 4WDs. Our workshop is equipped with a range of shock absorbers, struts, springs and suspension replacements to allow us to quickly fit new parts and get you back on the road safely.

Regular inspections and servicing of a car's steering and suspension systems ensure a more comfortable and safe drive. Steering wheel vibration, veering under braking pressure and excessive bouncing over uneven surfaces are all indicators there could be a problem. If this is the case, book a suspension and steering system inspection with Smithfield Car Diagnostics.


Your air-conditioning system requires regular servicing to ensure there are no leaks, cracked seals, worn hoses or other faults. Smithfield Car Diagnostics has state-of-the-art equipment to test car air-conditioners for performance. As an authorised Repco Service Centre, we also have the spare parts necessary for repairs and replacements.

Our air-conditioning services include:

  • Operating pressure checks
  • Inspection for leaks
  • Valve and thermostat check
  • Check for hose and seal damage, including cracks or breaks
  • Condenser temperature check
  • Drive belt tension check and tighten if necessary
  • Refrigerant recharge if necessary

An air-conditioner that is not sufficiently cooling the car can be a sign there is a gas leak. Arrange a service with Smithfield Car Diagnostics if you are concerned your car's airconditioner is not performing correctly.


The safe operation of your car or 4WD relies on an efficient braking system. Being able to stop in a hurry or even drive comfortably in traffic requires that your brakes be in good condition. At Smithfield Car Diagnostics, we can inspect and maintain your car's brakes to ensure they are safe and effective.

Our brake servicing and repairs include:

  • Inspection of brake pads
  • Brake fluid replacement or top-up
  • Brake disc machining

Pre-Purchase Inspections

If you are considering buying a second-hand car, it is advisable to have it inspected by a qualified mechanic. At Smithfield Car Diagnostics we can perform a thorough check of the vehicle's condition and advise you of any areas of concern. We can also advise you on the scheduled servicing requirements relating to that model. This ensures you don't get hit with an unexpected large bill after the first service.

150 Point Checklist

If you need to be sure about a vehicle, our comprehensive 150-point vehicle condition checklist can help you with the purchase decision. Our report offers you the most thorough understanding you'll ever need. As you can see from the following list of items checked it will ensure that you're actually getting what you have paid for.

Safety (Roadworthy) Certificates

Ensuring your vehicle is in safe and roadworthy condition is important for all drivers. At Smithfield Car Diagnostics, we perform thorough inspections in line with the standards set by the Department of Transport and Main Roads. Our workshop is an accredited vehicle inspection station, which means we can also issue roadworthy/safety certificates.

You will require a safety certificate when transferring the registration of your car from another owner, or when converting from interstate registration.

General Servicing

Even when your vehicle is no longer within the manufacturer's warranty period, it still requires regular servicing. Our Smithfield mechanics perform comprehensive checks and maintenance on your vehicle to ensure it is safe to drive and operating efficiently. We will also advise you of any upcoming maintenance that may be required as well.

Logbook Servicing

At Smithfield Car Diagnostics, we can perform logbook servicing in line with the manufacturer's standards. This means having your vehicle serviced with us will not void the warranty provided by the car's manufacturer. All servicing is carried out using recommended parts and fluids as well.

Once the servicing is complete, we will record and check-off the servicing in your logbook to certify the maintenance and repairs have been carried out. You can be confident in the quality of our workmanship.

To book your car in for scheduled servicing, please phone our office.

Fleet Car Servicing

At Smithfield Car Diagnostics, we understand fleet car needs can be different from those of the private road user. We can tailor our repair and servicing options to meet the requirements of many different fleet companies, ensuring efficient and affordable servicing.

We make it easy to maintain your fleet's mechanical needs, as well as keeping accurate reports on all servicing provided. We understand the constraints of fleet servicing and offer a convenient and cost-effective solution.

Speak to Zdenko or his mechanical team to discuss your specific servicing requirements.
