Hyundai R220 R210 Excavator Radiator LiuGong 922 XCMG 215 Cooling System

Product Specification

Product Overview

This versatile cooling system assembly serves Hyundai R220 and R210 excavators as well as LiuGong 922 and XCMG 215 models. The unit provides a complete radiator replacement package with brazed aluminum core, aluminum tanks, and mounting hardware, designed for general construction and infrastructure project applications.

Cause

Hyundai and Chinese-brand excavators are widely deployed across developing markets in Africa, Southeast Asia, and South America, where operating conditions vary from tropical heat with high humidity to arid desert environments with extreme dust levels. In tropical conditions, high ambient humidity reduces the evaporative cooling effect that supplements convective heat transfer, effectively reducing radiator efficiency by 5-10 percent compared to dry conditions. In arid environments, fine dust particles between 1-20 microns embed deeply in the fin stack and cannot be removed by standard compressed air cleaning, requiring more aggressive maintenance or earlier replacement.

Solution

The 3-row brazed aluminum core provides adequate cooling capacity across a wide range of ambient conditions from 0°C to 45°C. The 6000 series aluminum alloy construction offers a favorable balance of weight, thermal conductivity at approximately 205 W/(m·K), and structural strength for the 20-22 ton excavator class. The assembly includes new rubber mounting isolators to restore vibration damping between the radiator and the excavator frame, reducing fatigue stress on the brazed joints during extended service.

Application

Suitable for Hyundai R220, R210, LiuGong 922, and XCMG 215 excavators in road construction, building foundation work, irrigation projects, and general earthmoving across diverse climate zones. The 3-row core supports operation in ambient temperatures up to 45°C, making it appropriate for tropical and desert deployment. This complete assembly is recommended for machines with over 6,000 operating hours.

How It Works

The cooling assembly functions as an integrated liquid-to-air heat exchanger. Hot coolant from the diesel engine enters the inlet tank and distributes across three rows of aluminum tubes. Heat transfers from the coolant through the tube walls to the brazed aluminum fins, and the cooling fan forces ambient air through the fin stack to carry heat away. The cooled fluid collects in the outlet tank and returns to the engine. The rubber mounting isolators absorb structural vibration from the excavator frame, protecting the brazed joints from fatigue cracking that occurs when rigid mounting transmits vibration directly to the core.

How To Choose

Verify your excavator brand and model, as mounting patterns differ between Hyundai, LiuGong, and XCMG despite similar core dimensions. Confirm the OEM part number on your existing unit and measure core width, height, and thickness. For machines operating in tropical humid climates, the 3-row configuration provides the necessary thermal margin to compensate for reduced evaporative cooling efficiency.

FAQ

Q: Are the mounting brackets the same for all four brands?
A: No. Each brand uses different mounting patterns. Please specify your brand when ordering to receive the correct bracket configuration.

Q: How do I know when the radiator needs replacement?
A: Signs include persistent high coolant temperature, visible external leaks, rust-colored coolant, or cracked aluminum tanks.

Q: Can I use this radiator with a hydraulic oil cooler?
A: This unit does not include an integrated hydraulic oil cooler. Contact us if your machine requires this configuration.
