A radiator has one job: keep the engine at a safe operating temperature. On a mine site, heat, mud fouling and corrosion gang up to make that job far harder than it is on the open road, and once a cooling system loses that fight, you’re not looking at a radiator repair. You’re looking at a full engine rebuild.
TAKEO’s heavy-duty alloy radiator is built specifically to win that fight. A reinforced core, factory-applied corrosion protection and a design that copes with mud and heat instead of clogging under it, lasting up to 65% longer underground than a standard radiator.
Material choice matters for exactly this reason: aluminium is now the industry-standard radiator core material because it’s typically 25–60% lighter than the older copper/brass design, offers better corrosion resistance through single-piece brazed construction, and modern wide-tube aluminium cores can match or beat copper/brass on real-world cooling performance despite copper’s higher raw thermal conductivity.

Underground, TAKEO’s heavy-duty alloy radiator lasts up to 65% longer than a standard radiator before it needs replacing — the direct result of the reinforced core and corrosion protection built into it.
PREMIUM is a high-quality alloy alternative to the genuine radiator, built for surface mining, exploration crews and applications with less mud exposure. PREMIUM+ adds a special hourglass-welded tube design, a pressure-washable core and an anti-corrosion coating, making it the right choice for underground mining where heat, fouling and corrosion are constant threats.
Only the PREMIUM+ core is rated for pressure washing thanks to its reinforced hourglass tube construction. Pressure washing the standard PREMIUM core isn’t recommended, as it can damage the fins on a conventional tube design.
Yes, both PREMIUM and PREMIUM+ radiators are direct-fit replacements for the HZJ (16400-17400) and VDJ (16400-51030) LandCruiser.
Underground mines combine high ambient heat, low airflow from slow speeds and frequent stopping, heavy mud and dust fouling, and constant exposure to corrosive moisture — a combination genuine radiators simply aren’t engineered to handle long-term.
Aluminum radiators are typically 25–60% lighter than copper/brass units, resist corrosion better thanks to single-piece brazed construction, and modern wide-tube aluminum cores can match or exceed copper/brass on real-world cooling performance, even though copper has higher raw thermal conductivity.
