Technical Specification of Radiator 1851016 for Caterpillar 928G, 928H Loader

The radiator with OE number 1851016 (also marked as 185-1016) is a high-performance, heavy-duty water cooling component specifically designed for Caterpillar 928G and 928H wheel loaders, and it is also compatible with Caterpillar 924G, 924H, 930G, 930H, and IT28G loaders. It is perfectly matched with Caterpillar 3056E and C6.6 ACERT diesel engines, engineered to meet the rigorous heat dissipation needs of heavy construction and loading operations, ensuring stable engine performance under continuous high-load conditions.

This radiator features precise dimensional parameters that fully conform to the original equipment standards, enabling direct replacement without any modifications. In terms of overall dimensions, the total height including mounting brackets is approximately 48 inches (1219 mm), and the total width is also about 48 inches (1219 mm), which is consistent with the installation space of the target loader models, ensuring a seamless fit with the engine compartment.

The core part of the radiator — the key to heat dissipation efficiency — has detailed and standardized dimensions. In the industry, it is commonly marked as 820 × 770 × 125 mm, which is a standard size for heavy-duty loader radiators, facilitating the replacement and matching of spare parts.

For the connection dimensions, the inlet and outlet diameters are both 2-1/2 inches (63.5 mm), which perfectly matches the engine’s water inlet and outlet interfaces, ensuring smooth water flow and efficient heat transfer. The mounting brackets are designed in strict accordance with the original OEM standards, with accurate hole positions and spacing, allowing for quick and easy installation without drilling or adjusting the mounting points.

Made of full aluminum material, including aluminum tanks and a plate-fin core, the radiator weighs approximately 175 lbs (79.4 kg) and has a working pressure of 2.0 MPa (20 bar). Its precise dimensional design, combined with a 5-row tube structure and 9–10 fins per inch, ensures excellent heat dissipation performance, making it suitable for harsh construction environments with dust, vibration, and high temperatures.
