Technical Details and Construction

This CSF radiator (part number 3938) features a cross flow core type, which allows coolant to flow horizontally across the radiator core. The aluminum core material enhances thermal conductivity, helping maintain engine temperatures within optimal ranges. With a core thickness of 5/8 inch and a width of 3 inches, the radiator balances cooling capacity and compact size. The single-row core design is tailored for the cooling demands of heavy-duty Chevrolet and GMC trucks, including the Sierra 2500 HD and Silverado 3500 HD models.

This radiator is compatible with the following vehicles:

• Chevrolet Sierra 2500 HD
• Chevrolet Sierra 3500 HD
• GMC Sierra 2500 HD
• GMC Sierra 3500 HD
• Chevrolet Silverado 2500 HD
• Chevrolet Silverado 3500 HD

It is designed to replace factory radiators that require a cross flow, single-row aluminum core radiator with similar dimensions.

Common Issues Addressed by This Radiator

• Overheating due to radiator core damage or clogging
• Coolant leaks from cracked or corroded radiator cores
• Reduced cooling efficiency from worn or bent fins
• Engine temperature fluctuations impacting performance
• Replacement of failed or underperforming factory radiators

Installation Notes and Tips

When installing the CSF radiator 3938, ensure the radiator cap from the original unit is reused, as this product does not include a cap. Verify all hose connections and mounting points align with the vehicle’s specifications. It is recommended to flush the cooling system before installation to remove debris and contaminants. Proper bleeding of the cooling system after installation will help prevent air pockets and ensure optimal performance.
