Natrad Radiators Gladstone | Cooling Systems & Heavy-Duty Parts
Total Mobile Mechanical Services is an authorised Natrad dealer supplying and installing radiators and cooling-system components for Gladstone, Calliope and Central Queensland. We support cars, 4WDs, utes, trucks, fleets and machinery with Natrad product access, proper diagnosis and workshop-based installation.
A replacement radiator needs to suit the vehicle, its workload and the cause of the original failure. Central Queensland heat, towing, heavy loads, dust and extended operating hours can place far more demand on a cooling system than ordinary short-distance driving.
As a Natrad dealer, we can source suitable radiator and cooling components and install them through a large, fully equipped mechanical workshop. The team also has advanced diagnostic capability and a qualified auto electrician, allowing mechanical cooling faults and electrical fan or control faults to be assessed together.
Natrad provides the backing of an Australia-wide cooling and vehicle climate-control network. Customers still receive local diagnosis and straightforward advice from Total Mobile Mechanical Services.
Correct diagnosis and fitment matter as much as choosing the radiator itself.
Gladstone Radiators Backed by the Natrad Network
Searches for Gladstone radiators can describe several different needs: a leaking car radiator, a heavy-duty truck core, an overheating 4WD, a damaged intercooler or a replacement cooling component for working machinery. This page covers the Natrad product and network side of the service, then directs each repair to the most relevant specialist team.
- Cars, 4WDs and utes: overheating diagnosis, coolant leaks, fans, thermostats, water pumps, hoses and radiator replacement are covered on our car cooling-system and radiator repair page.
- Trucks and heavy vehicles: higher-capacity systems, heavy-duty radiators and cooling faults under load are covered through truck cooling-system and radiator repairs.
- Vehicle air conditioning: condenser, evaporator and refrigerant-system diagnosis is handled under ARCtick authorisation AU62626. Visit vehicle air conditioning.
- General servicing and AutoCare: scheduled vehicle maintenance, brakes and related work can be coordinated through Natrad AutoCare Gladstone and Calliope.

Natrad Radiators and Cooling Components
The correct product depends on the vehicle identification, dimensions, configuration, workload and availability. Depending on the application, the Natrad range and associated supplier pathways can include:
- Passenger-car, SUV, 4WD and light-commercial radiators
- Truck, fleet and heavy-duty radiator assemblies
- Radiator cores and application-specific replacement options
- Intercoolers and charge-air cooling components
- Engine-oil, transmission and power-steering coolers
- Air-conditioning condensers, evaporators and heater cores
- Cooling fans, hoses, caps and connected components
- Heavy-duty or upgraded cooling options where available for the application
We confirm the application before recommending a part. If a standard replacement does not suit a modified, industrial or hard-working vehicle, we can investigate the available Natrad or specialist supply options rather than promising that an unsuitable generic component will solve the problem.
Radiator Cores for Gladstone Vehicles and Equipment
Heavy-duty cooling needs to be matched to load, operating conditions and the complete system.
A radiator core transfers heat from the coolant to the airflow passing through the radiator. Core size, construction, condition and airflow all affect cooling performance. A blocked, corroded or damaged core may contribute to overheating, but the rest of the system must also be assessed.
For customers searching for radiator cores in Gladstone, we can inspect the existing assembly, identify the application and investigate suitable replacement, upgraded or specialist options. Availability and the best repair pathway depend on the radiator design, equipment type and whether a complete assembly or core-based solution is appropriate.
We do not treat every hot-running vehicle as a radiator-only problem. Cooling-system pressure, fan operation, thermostat control, coolant circulation, hose condition and possible engine faults all need consideration.
Diagnosis Before Radiator Replacement
Replacing a radiator without finding the cause of overheating can waste money and damage the new part. The original failure may have been caused by poor coolant condition, a faulty pressure cap, failed fan, thermostat problem, water-pump issue, combustion-gas intrusion, blocked airflow or an electrical control fault.
Where practical, diagnosis can include:
- Visual inspection for coolant staining, damage and external leaks
- Cooling-system pressure testing and cap assessment
- Fan, relay, wiring and control checks
- Temperature and operating-behaviour checks
- Hose, thermostat and coolant-circulation assessment
- Scan-data review where electronic temperature control is involved
- Further engine testing when symptoms indicate a deeper fault
The confirmed cause and repair priorities are explained before material additional work is completed.
Cooling for Towing, Fleet and Heavy-Duty Work
Vehicles that tow, haul, idle for long periods or work in dust and heat can expose weaknesses that are not obvious during light driving. Extra load increases engine, transmission and charge-air temperatures, while restricted airflow or contaminated cooling surfaces reduce the system's ability to reject heat.
A suitable solution may involve restoring the original system, correcting an airflow or control fault, or sourcing a higher-capacity component where the application supports it. The team considers how the vehicle is actually used rather than recommending an upgrade simply because it sounds better.
Our fully equipped mobile workshop can assist with suitable breakdown assessment and field work. Repairs requiring controlled testing, lifting equipment or major removal are normally completed in the workshop, backed by the broader mechanical and auto-electrical team.

Natrad Radiator FAQs
Do you supply Natrad radiators in Gladstone?
Yes. Total Mobile Mechanical Services is an authorised Natrad dealer supporting customers across Gladstone, Calliope and Central Queensland. Supply and fitment depend on confirming the correct application and product availability.
Can you source radiator cores?
We can identify the existing radiator and investigate suitable core, complete-assembly, heavy-duty or specialist options. The right pathway depends on the design, condition and vehicle or equipment application.
Do you repair truck and machinery cooling systems?
Yes. The team works across trucks, fleets and machinery as well as passenger vehicles. Heavy vehicles should use the dedicated truck cooling page so the booking is matched to the correct workshop capability.
Can you diagnose an overheating vehicle?
Yes. Diagnosis may include pressure testing, fan and electrical checks, temperature assessment, cooling-component inspection and further engine testing where symptoms require it.
Is every overheating problem caused by the radiator?
No. Thermostats, fans, pumps, pressure caps, hoses, coolant condition, airflow, electrical controls and internal engine faults can all contribute. Testing should guide the repair.
