A classic truck that runs hot is a truck that doesn't get driven. Whether you're doing a frame-off restoration, building a high-horsepower restomod, or simply refreshing a tired cooling system on a daily driver C10, keeping your engine at the right operating temperature starts with the right parts. H&H Classic Parts carries one of the most complete selections of cooling system and radiator restoration parts for 1955–1987 Chevy and GMC trucks, Suburbans, and classic Blazers — from factory-correct replacement components to high-performance aluminum radiators built for modern engines.
Aluminum Radiators for Classic Chevy & GMC Trucks: Cold Case Performance
For builders who demand more cooling capacity than a stock radiator can provide, Cold Case Radiators is the go-to choice in the classic truck market. Cold Case was founded on a straightforward mission: make high-quality aluminum performance radiators and accessories available and affordable to every builder, regardless of budget. Their products don't cut corners to hit a price point — every radiator is TIG-welded from aircraft-grade aluminum and engineered for direct-fit installation in specific classic vehicle applications.
Why Upgrade to an Aluminum Radiator?
Factory brass and copper radiators in 1955–1987 Chevy and GMC trucks were designed around the cooling demands of stock engines from that era. If you've added a crate engine, increased displacement, upgraded to a high-output carb, or simply want more reliable cooling in stop-and-go traffic or summer heat, an aluminum radiator delivers measurably better thermal performance. Aluminum transfers heat more efficiently than brass and copper, and Cold Case's multi-row core designs push that advantage even further.

Brass & Copper Radiators for Stock-Correct Restorations
For numbers-matching builds and show trucks where factory correctness matters, we also carry brass and copper radiators that restore your truck's cooling system to original spec. These are the right choice when authenticity is the priority and the engine build stays close to stock.

Electric Fan Kits, Fan Shrouds & Cooling System Accessories
A great radiator is only as effective as the airflow moving through it. H&H Classic Parts carries a full range of cooling system accessories to make sure your setup performs at its best under any conditions.
Electric Fan Kits for Classic Trucks
Swapping to an electric cooling fan is one of the most popular upgrades for classic truck builders. Eliminating the engine-driven mechanical fan frees up horsepower, improves airflow control, and makes room for other accessories. We carry electric fan kits from Spal USA, one of the most respected names in high-performance electric cooling fans, alongside kits from American Autowire designed for clean, reliable integration into classic truck electrical systems. Shop electric fan kits at hhclassic.com/c-755888-truck-radiator-parts-electric-fan-kits.html.
Radiator Fan Shrouds
A fan shroud is one of the most overlooked components in a classic truck cooling system — but it plays a critical role in directing airflow through the entire radiator core rather than just the area directly in front of the fan. We carry correct-style replacement shrouds for 1955–1987 Chevy and GMC trucks from trusted suppliers including OER Parts, Dynacorn, and Counterpart Automotive. Shop fan shrouds at hhclassic.com/c-755889-truck-radiator-parts-fan-shrouds.html.
Overflow Tanks, Radiator Caps, Mounting Brackets & Core Support Parts
We stock every supporting component needed for a complete cooling system restoration or upgrade, including overflow tanks, radiator caps, radiator mounting brackets and cushions, and radiator core support parts. Whether you need a concours-correct cap for your show truck or a clean overflow tank that tucks neatly into a restomod engine bay, you'll find the right part here.

FAQs: Classic Chevy & GMC Truck Cooling System Parts
What years of Chevy and GMC trucks do these cooling system parts fit?
This category covers 1955 through 1987 Chevy and GMC trucks, including C10, C20, C30, K10, and K20 pickups, full-size Suburbans, and classic Blazers. Cooling system parts are application-specific — fitment depends on your model year, engine size, and whether your truck was originally equipped with AC. Use the sidebar filters to narrow results by year and sub-category, or call our team at 479-787-5575 to confirm the right part for your specific application before ordering.
Should I upgrade to an aluminum radiator or restore my original brass and copper radiator?
It depends on your build goals. If you're doing a factory-correct restoration and your engine is close to stock spec, a brass and copper replacement radiator is the right call — it preserves the original appearance and provides adequate cooling for a stock or mildly modified engine. If you've added a crate engine, increased displacement, deleted the AC compressor, or plan to drive the truck in hot weather or stop-and-go traffic, a Cold Case aluminum radiator will give you significantly more cooling capacity and long-term reliability. Our team can help you evaluate which direction makes sense for your build.
What is the advantage of a Cold Case aluminum radiator over a stock replacement?
Cold Case aluminum radiators are engineered for maximum heat dissipation using aircraft-grade aluminum and TIG-welded construction. Compared to stock brass and copper units of the same size, aluminum transfers heat more efficiently, which translates to lower sustained operating temperatures — especially under load. Cold Case also designs their radiators for direct-fit installation in specific classic vehicle applications, so you get performance-level cooling without any custom fabrication. Every Cold Case unit is built to be affordable without sacrificing the quality that demanding builds require.
Do electric fan kits from Spal USA work with the stock wiring in my classic truck?
Spal USA electric fans are high-quality units, but classic truck wiring from the 1955–1987 era typically requires a relay harness or wiring upgrade to properly handle the electrical load of an electric cooling fan. American Autowire offers relay harness kits specifically designed to integrate electric fans into classic truck electrical systems cleanly and safely. H&H Classic Parts carries both Spal fans and American Autowire wiring components, and our team can help you spec the correct combination for your truck's setup. Call 479-787-5575 or submit an inquiry online.
