Heavy-Duty Radiators
Specialized radiators designed to handle high-performance cooling in demanding environments, such as heavy-duty vehicles, construction equipment, agricultural machinery, and industrial applications. These radiators are built to withstand harsh conditions, heavy usage, and high-temperature environments, ensuring optimal engine cooling and preventing overheating.
-
Engineered to meet or exceed OE manufacturer’s specifications
For Heavy Duty vehicles that are under extreme conditions or high mileage, you need to go beyond the OE specifications to have a product that will perform and go the distance.
-
Industry-Leading Technology
It is important to have the product of today but to also be looking forward to the new technologies of tomorrow. OSC knows the value of investing in the future.
-
Drop-in fit, form and function
OSC understands that it is very important that each part goes in as easily as the existing one comes out and that it looks and functions like the original unit. OSC focuses on this requirement.
Why OSC HEAVY-DUTY Radiators?

Heavy-Duty Radiators
- Many models have a welded double header design – reduces flexing
- All “Tabbed-Over” models have a second crimp strip
- Most applications come with mounting hardware
- Superior stainless steel coolers replaces OE aluminum
- More than 50 models available with frames
- Over 450 SKU’s covering class 8 trucks and forklifts
Resin Reinforced Headers Prevent Leaks
OSC heavy-duty radiators often feature resin-reinforced headers as part of their design, which helps prevent leaks and enhances the overall durability of the radiator. The resin used in these reinforced headers forms a strong bond between the core and the header tanks. This improves the overall seal integrity, reducing the chances of coolant leaks that can occur due to wear, corrosion, or poor fitting. In short, resin-reinforced headers in OSC heavy-duty radiators provide a high level of protection against leaks, ensuring better performance, longevity, and reliability in demanding environments.


Key Features of OSC Heavy-Duty Radiators:
Durability: Constructed with robust materials like aluminum or high-grade metals to endure tough conditions and resist wear and tear.
High-Performance Cooling: Engineered to provide efficient heat dissipation, keeping engines at optimal operating temperatures even under heavy loads.
Corrosion Resistance: Many models feature coatings or materials that resist corrosion from environmental factors such as road salt, dust, and moisture. Advanced Design: Designed with larger cores and fin structures to maximize airflow and cooling capacity.
Custom Fit: Often tailored to fit specific models of machinery, trucks, or industrial equipment for precise cooling performance.
