21T-03-31711
The 21T-03-31711 radiator core serves as a critical heat exchanger. It enables efficient heat transfer, facilitating the dissipation of thermal energy from the engine coolant to the ambient air. This component is specifically engineered for the Komatsu PC2000-8 Excavator.
Features
It stands up to the high pressure and temperature changes inside the cooling system—so you won’t have to deal with costly leaks or unexpected downtime.
By increasing the surface area for heat exchange, it cools your system quicker and more effectively, keeping your equipment running smoothly.
