Parts for your 2023 Mitsubishi Triton-Radiator

2023 Mitsubishi Triton radiator — what it does and how to look after it

Based on technical sources including the 2023 Mitsubishi Triton Owner’s Manual, Mitsubishi Motors Service/Workshop Manual (Cooling System section), and the MMC parts catalogue for the MR-series Triton, this model is fitted with a liquid-cooled engine using an aluminium crossflow radiator. The radiator is therefore relevant to the 2023 Mitsubishi Triton and forms a core part of its cooling system.

The radiator’s job is simple but critical: it sheds the engine’s heat to keep temperatures in the sweet spot, whether the ute is commuting, towing a boat, or crawling along a rutted track in summer. Coolant circulates from the engine to the radiator, where airflow and the cooling fans pull heat out before sending it back through the block and head. On some variants, ancillary coolers (such as for the transmission or intercooler/condenser stacks nearby) are packaged around the radiator, so good airflow and clean fins matter.

As part of regular servicing, the radiator and cooling system deserve a once-over. Mitsubishi specifies using the correct long‑life coolant that meets its factory specification
