Radiator GM C & K Series Truck 33.25in x 18.62in

The Radiator GM C & K Series Truck 33.25in x 18.62in is a direct-fit cooling solution engineered for Chevrolet and GMC light-duty trucks spanning multiple generations. Built by Griffin, a manufacturer with decades of radiator expertise, this unit replaces factory cooling systems that have degraded over time or cannot handle modern driving demands, modified engine outputs, or heavy-duty towing applications. Whether you're restoring a classic pickup, upgrading a work truck's thermal capacity, or rebuilding an engine bay after performance modifications, this radiator delivers the core-to-core dimensions and mounting geometry your C & K platform requires.

Griffin's construction prioritizes efficient heat rejection through optimized fin density and internal tube design, ensuring coolant flows smoothly while maximizing surface area contact with ambient air. The 28.03-pound assembly integrates seamlessly with your truck's OEM fan shroud and water pump, maintaining proper coolant velocity to prevent hot spots and vapor lock—especially critical when running higher thermostat settings or pushing engine RPMs during acceleration or uphill grades. Brass and copper core construction, paired with modern epoxy-sealed tanks, resists corrosion from glycol-based coolants and mineral deposits, extending service intervals compared to aging factory units that lose efficiency after 100,000+ miles.

This radiator suits truck owners tackling everything from daily commutes to full towing loads, and those upgrading cooling after cam swaps, carburetor tuning, or boosted engine work. Installation requires standard socket and wrench tools; most experienced mechanics complete the job in under two hours once the front grille and shroud are removed. Verify your truck's year and engine displacement against GM C & K specifications before ordering to ensure proper hose connections and mounting bracket alignment with your specific model.
