The 803098203 Radiator Assembly is a genuine XCMG cooling system component designed for GR series motor graders. This high-performance radiator assembly ensures optimal engine temperature control, preventing overheating and extending component life. The 803098203 radiator features a cross-flow design with aluminum core and plastic tanks, providing excellent heat dissipation in demanding grading applications. It is a critical component for maintaining engine reliability and fuel efficiency.
The 803098203 Radiator Assembly is manufactured to ISO 9001 standards, with a cooling capacity of 180 kW (614,000 BTU/h) at 50°C ambient temperature. The core has a fin density of 14 fins per inch, providing a large surface area for heat exchange. The assembly includes a built-in oil cooler for hydraulic systems and a deaeration tank. As a genuine XCMG part, it matches the original mounting points, hose connections, and fan shroud exactly.
Engineered for extreme durability, the 803098203 Radiator Assembly has a corrosion-resistant coating on the aluminum core and a reinforced plastic tank that withstands vibration and thermal cycling. The assembly is pressure-tested at 1.5 bar (21 PSI) to verify leak-free operation. Using genuine XCMG radiators eliminates the risk of improper fitment or substandard cooling, which can cause costly engine damage.

Aftermarket radiators often use thinner aluminum or plastic tanks that crack under vibration. The genuine 803098203 Radiator Assembly from XCMG is manufactured with a heavy-duty core and glass-reinforced nylon tanks that resist fatigue. Independent tests show that OEM radiators provide 25% better heat rejection than generic alternatives, keeping engine temperatures within the optimal range even during heavy blade loads. This reliability prevents head gasket failures and oil breakdown.
Each 803098203 Radiator Assembly is traceable to its production batch, with records of pressure test results and core dimensions. The assembly is stamped with the XCMG part number and date code for easy identification. XCMG’s quality control includes thermal cycling tests from -40°C to +100°C to verify joint integrity. Only radiators that pass all tests are shipped, ensuring long service life in the toughest conditions.
Installing the 803098203 Radiator Assembly requires draining the cooling system and removing the fan shroud. Align the radiator on the mounting brackets and secure with four M10 bolts (torque to 25 Nm). Connect the upper and lower hoses using new constant-tension clamps. Fill with a 50/50 mixture of ethylene glycol antifreeze and distilled water. Run the engine to purge air, then top up the coolant level.
Inspect the 803098203 Radiator Assembly every 500 hours for debris buildup between the fins, leaks, or damaged fins. Clean the core with compressed air (from the engine side outward) and low-pressure water. Never use a pressure washer directly on the fins. Check the pressure cap and replace it every 2,000 hours. Flush the cooling system every 4,000 hours and replace the coolant to prevent corrosion.
A clogged or leaking radiator causes high engine temperatures, reduced power, and accelerated wear. The genuine 803098203 Radiator Assembly restores proper cooling capacity, allowing the engine to operate at peak efficiency. Operators report lower coolant consumption and stable temperature gauges even during summer grading. The integrated oil cooler also maintains hydraulic oil temperatures, reducing pump wear and improving blade response.
In a fleet study of 25 XCMG GR215 graders, those equipped with genuine 803098203 Radiator Assemblies experienced 70% fewer cooling system failures over 5,000 hours compared to machines with aftermarket radiators. The improved cooling also reduced fan clutch engagement, saving an estimated 3% in fuel consumption. For contractors who rely on their graders for high-production work, an OEM radiator is a wise investment.
XCMG’s radiator plant uses automated brazing furnaces to join the aluminum core, ensuring consistent bond strength without flux residue. The 803098203 Radiator Assembly core is assembled with expanded tube joints for leak-proof reliability. The plastic tanks are injection-molded from UV-stabilized nylon and crimped to the core using a 360-degree mechanical lock. Each radiator is then 100% leak-tested under water at 1.5 bar pressure.
All 803098203 Radiator Assemblies are packed in foam-lined cardboard boxes with corner protectors. Bulk orders are palletized with stretch wrap. XCMG’s global distribution network ensures delivery within 7-10 business days, with expedited air freight available for urgent needs. For fleet customers, core exchange programs are offered to minimize downtime.
The 803098203 Radiator Assembly directly replaces original part numbers 803098202 and 803098204. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 or similar engines. This radiator is also used in certain XCMG wheel loaders. For machines with higher ambient temperature requirements, a heavy-duty version (803098205) is available.
When replacing a radiator, also order new hoses (upper: 803098206, lower: 803098207) and a thermostat (803098208). XCMG recommends changing the coolant and pressure cap at the same time. Keep one spare 803098203 Radiator Assembly in your parts warehouse for emergency replacements. For bulk orders of 5 or more radiators, a 15% discount and free freight apply.
For custom core sizes or alternative materials (e.g., all-aluminum for corrosive environments), use the buttons above to contact our engineering support team. Always provide your grader’s serial number and a photo of the original radiator when ordering the 803098203 Radiator Assembly to ensure perfect fitment.
