6-Pass Econo-Cool Rplcmn t Core (1/2in)

The DERALE 6-Pass Econo-Cool Replacement Core with 1/2-inch hose barb connections is a heavy-duty fluid cooler engineered for vehicles requiring sustained thermal management under demanding conditions. This aluminum and copper construction unit delivers reliable cooling performance in compact form, making it an effective solution for engine cooling, transmission fluid regulation, and auxiliary hydraulic systems across light-duty to mid-range platforms.

The 6-pass tube design maximizes heat dissipation by routing fluid through multiple internal passages, increasing dwell time and cooling surface area. The 1/2-inch hose barb male inlet and outlet configuration integrates with standard SAE hose sizing common on aftermarket and OEM cooling systems. Black powder coat finish protects against corrosion and UV degradation. Measuring 8.05 x 2.15 x 18.7 inches and weighing 1.81 pounds, this replacement core fits the existing Econo-Cool housing or serves as a direct-fit upgrade where compatible mounting points are present.

This product addresses the need for efficient, cost-effective cooling in applications where stock systems prove marginal—particularly in vehicles with performance modifications, towing packages, or extended idling duty cycles. Off-road, patrol, and motorsport operators benefit from the improved thermal stability this core provides. The replacement core format allows field maintenance without complete system overhaul, reducing downtime and labor cost compared to full cooler replacement.

DERALE is recognized within the automotive thermal management industry for manufacturing OEM-quality cooling components at competitive pricing. The Econo-Cool series occupies the proven middle ground between budget and premium coolers—delivering measurable performance gains without premium-tier investment. This replacement core maintains that positioning, making it a practical choice for shops and operators who understand the value of deliberate thermal engineering.
