Natrad
Natrad Radiators, Heavy-Duty Cooling & Air Conditioning Specialists – Gladstone, Calliope & Central Queensland
Total Mobile Mechanical Services is an authorised Natrad Dealer for Gladstone, Calliope and Central Queensland, supplying and installing premium radiators, heavy-duty cooling systems, intercoolers, oil coolers and automotive air-conditioning components for cars, 4WDs, trucks, fleets and machinery.
Natrad is trusted across Australia for cooling and vehicle climate control engineered for harsh conditions. For Central Queensland heat, humidity, towing loads, dust, stop-start operation and off-road use, the right cooling system matters — not just for comfort, but for reliability and engine protection.
All Natrad components are supplied, diagnosed and installed from our fully equipped workshop at 6 Wright Road, Calliope, with professional fitting, system testing and warranty-backed support.
Why Choose a Natrad Dealer?
Choosing an authorised Natrad dealer is not the same as buying a generic radiator online or fitting low-cost components without proper testing.

- Correct radiator and condenser fitment
- Cooling system flushing and correct bleeding
- Correct coolant selection (OAT, HOAT and modern formulations)
