The Caterpillar Modular Radiator (often referred to as the Next Generation Modular Radiator or NGMR) is a patented cooling technology designed by Caterpillar to maximize machine uptime. Unlike a single-piece radiator core, the modular system consists of multiple smaller radiator "segments" or "cores" stacked together to form a large cooling matrix.

This design is a staple in CAT 777, 785, 789, and 793 Mining Trucks, as well as D8 through D11 dozers.

The Caterpillar 345 series excavators utilize integrated radiator and cooler assemblies to manage engine and hydraulic system temperatures. These assemblies are crucial for maintaining optimal performance and preventing overheating during heavy-duty operations.
