Brisbane's heavy equipment operators, from logistics hubs in Acacia Ridge and Rocklea to fleets across the South East Queensland corridor, need a repair partner with the engineering depth to fix cooling problems right the first time.

What Does Heavy Duty Radiator Repair Actually Include?
Heavy duty radiator repair covers far more than patching a leak. A thorough assessment may include core re-coring, pressure testing, charge-air cooler inspection, oil cooler service, and full system cleaning. L&M Radiator's MESABI® flexible core design means individual cooling tubes can often be replaced without condemning the entire unit, reducing both cost and turnaround time.
Services that may be part of a repair assessment include:
1. Initial inspection and pressure testing to locate leaks, blockages, and structural fatigue.
2. Individual tube replacement or full core re-coring using genuine MESABI® components.
3. Oil cooler and charge-air cooler inspection, cleaning, and repair where required.
4. Full system flush to remove debris, scale, and contaminated coolant.
5. Post-repair pressure test and sign-off to confirm restored cooling performance.
The MESABI® flexible core system is engineered so that tubes are individually replaceable without soldering or specialised welding, meaning repairs can often be completed faster and with less disruption to your schedule.
What Types of Equipment Can Be Repaired?
L&M Radiator has engineered MESABI® products for OEM partners including Caterpillar, Komatsu, Liebherr, Sandvik, and Atlas Copco, with experience spanning the full breadth of heavy equipment found on Queensland mine sites, construction projects, and port operations. Equipment types that may be serviced include large mining haul trucks and excavators, road transport prime movers and heavy haulage vehicles, stationary and portable generators, industrial fixed-plant machinery, and construction equipment including graders, dozers, and loaders.
Whether your equipment runs in the Port of Brisbane precinct, along the Ipswich Motorway freight corridor, or on projects stretching toward the Sunshine Coast, MESABI® solutions are engineered to match Queensland's climate and terrain.
Why the MESABI® Flexible Core Design Matters for Repair
The MESABI® flexible core uses individual copper tubes secured with flexible rubber seals rather than soldered or brazed joints. A damaged tube can be replaced without removing the entire core, which may allow repairs to be completed at the worksite or with faster workshop turnaround. It is a practical advantage for Brisbane operators who cannot afford extended equipment downtime.

Frequently Asked Questions
Can a Heavy Duty Radiator Be Repaired Instead of Replaced?
In many cases, yes. MESABI® flexible core radiators are specifically designed to be field repairable, allowing individual tubes to be swapped out rather than replacing the entire unit. Whether repair or replacement is appropriate depends on the extent of damage, which a qualified technician can assess after inspection.
How Long Does a Heavy Duty Radiator Repair Take?
Turnaround time depends on the scope of work and parts availability. MESABI® products use genuine replacement tubes and seals that L&M Radiator may have on hand, which can help speed up the process. Contact the team directly to discuss your equipment and expected lead times.

What Is Included in a Pressure Test for a Heavy Duty Radiator?
A pressure test checks the cooling system for leaks, weak points, and structural integrity under operating conditions. It is typically one of the first diagnostic steps in any heavy duty radiator repair assessment and helps determine whether targeted repair or a full re-core is the appropriate course of action.
