Compatible Models
Common Case backhoe loader models requiring reliable radiator replacements include:
Replacement radiators for these models come primarily in two configurations: with or without oil coolers. Key specifications include:
Most replacement radiators utilize heavy-duty aluminum cores and tanks for efficient heat dissipation and corrosion resistance. High-quality welds and durable end tanks help ensure long service life, critical when operating heavy-duty equipment in demanding environments.
OEM and Aftermarket Options
Supporting components are often replaced in radiator service, including:
In a heavy construction operation in the Midwest, frequent overheating of a Case 580CK backhoe threatened project delays. Replacing the aging radiator with a high-quality aftermarket unit of matched specifications restored optimal engine temperatures and hydraulic performance, demonstrating the importance of reliable cooling system components in heavy equipment uptime.
Conclusion
Selecting the proper replacement radiator for Case backhoe loaders is critical to maintaining engine and hydraulic system temperatures, preventing downtime and costly repairs. While OEM radiators guarantee perfect fit and reliability, aftermarket options provide economical alternatives. Attention to cooling system maintenance and compatibility of associated components like hoses and fan shrouds enhances equipment longevity and performance on challenging job sites.
Common Case backhoe loader models requiring reliable radiator replacements include:
- 430CK
- 480CK and 480B
- 530CK
- 580CK and 580B
Replacement radiators for these models come primarily in two configurations: with or without oil coolers. Key specifications include:
- Core dimensions: Approximately 18-1/2” height by 19” width, with a depth near 3-1/2”
- Overall radiator size: Around 24” height by 21-1/8” width
- Core rows: Typically 5 rows with 10 fins per inch, usually flat fin design
- Inlet size: 1-3/4” diameter
- Outlet size: 2-1/4” diameter
- Fill neck height commonly 3/4” from base

OEM and Aftermarket Options
- OEM Radiators, identifiable by part numbers such as 239739A2 and 234876A1, offer exact fit and finish for Case backhoes but carry premium pricing, generally ranging around $900 or more.
- Aftermarket radiators provide cost-effective alternatives often priced between $400 and $700, with compatibility spanning multiple Case models.
- Industrial suppliers offer both new and rebuilt radiators to suit budget and availability constraints.
Supporting components are often replaced in radiator service, including:
- Upper and lower radiator hoses tailored to fit specific backhoe models
- Radiator fan shrouds and mounts ensuring proper airflow
- Radiator steel isolators and vibration dampers to reduce stress on radiator mounts during machine operation
- Regularly inspect radiators for damage, leaks, and core blockages due to dirt or debris
- Clean cooling fins periodically with compressed air or low-pressure water to maintain airflow efficiency
- Monitor coolant levels and quality, using manufacturer-recommended antifreeze mixtures
- Check all hoses and connections for tightness and wear to avoid undercooling or leaks
- Core Rows: Layers of cooling tubes within the radiator core through which coolant flows
- Fins per Inch: Density measure showing cooling surface area efficiency
- Oil Cooler: A heat exchanger cooling transmission or hydraulic oil, often integrated with radiators
- End Tanks: Made of aluminum or plastic, enclose coolant flow through the radiator
- OEM (Original Equipment Manufacturer): Parts made by the original equipment builder ensuring exact specifications
