Hayden 1046 Swirl-Cool Heavy Duty Engine Oil Cooler for Chevrolet V8 Engines

Protect your Chevrolet V8 engine from the destructive effects of overheating oil with the Hayden Swirl-Cool 1046 Heavy Duty Engine Oil Cooler. Excessive engine oil temperatures accelerate oil breakdown, reduce lubrication effectiveness, and can lead to costly internal engine damage — issues this cooler is purpose-built to address. The 1046 features a robust copper header and tube core construction measuring 1-1/2" thick x 6-1/2" high x 18" long, delivering a large 14-1/4" cooling surface area. Turbulators inside every tube maximize heat dissipation by increasing fluid contact with the cooler surfaces, while the headered crossflow design keeps pressure drop to a minimum — so your oil keeps moving where it needs to go. Specifically engineered for Chevrolet V8 engines, this kit includes a metal line kit designed to route oil lines safely past the exhaust manifold — a critical detail for Chevy V8 installations that generic coolers don't account for. The thermostatic controlled sandwich adapter installs between the engine block and oil filter, and the vibration-absorbing rubber block mounting system protects the cooler from road vibration and engine movement. Each 20°F reduction in oil temperature can effectively double oil life, helping extend engine longevity and reduce maintenance costs over time. Whether you're running a classic Chevy, a work truck, or a performance build, the Hayden 1046 is a direct upgrade for any Chevrolet V8 application that runs hard.

• Engineered For Chevrolet V8 Engines — Specially designed for Chevrolet small block and big block V8 applications; includes a metal line kit to properly route oil lines past the exhaust manifold for a clean, reliable installation. For vehicles requiring an M22 x 1.5 fitting, use P/N 271.
• Heavy Duty Copper Header And Tube Construction — Built with copper headers and tubes for superior thermal transfer and long-lasting durability, even in high-heat, high-demand operating conditions such as towing, hauling, and performance driving.
• Turbulators In Every Tube For Maximum Cooling Efficiency — Internal turbulators in every tube actively increase fluid agitation and contact time with the cooler core, significantly improving heat dissipation without restricting flow.
• 1-1/2" Thick Headered Design With Minimal Pressure Loss — The 1-1/2" thick headered core design increases cooling capacity and efficiency while the crossflow round tube layout maintains minimal pressure drop across the system, preserving engine oil circulation.
• Complete Kit With Mounting Hardware Included — Kit includes the oil cooler (1-1/2" x 6-1/2" x 18", 14-1/4" core, 1/2" FPT fittings), metal line kit, thermostatic controlled sandwich adapter, and vibration-absorbing rubber block mounting hardware for a straightforward installation. Universal fit — not a direct OE replacement; verify fitment before installation.
