Engine Oil Cooler 2.75in x 11in x 1.5in

The TRU-COOL Engine Oil Cooler 2.75in x 11in x 1.5in is purpose-built for serious automotive enthusiasts and mechanics who demand engine temperature control during high-performance driving, towing, or extreme conditions. This plate-type fluid cooler serves as a critical cooling circuit component, preventing oil degradation and viscosity breakdown that can occur under sustained load. Whether you're upgrading a street performance engine, preparing a track vehicle, or enhancing a heavy-duty tow setup, this cooler maintains optimal oil temperatures by circulating fluid through aluminum core passages.

Constructed from lightweight aluminum with durable black paint finish, the Engine Oil Cooler features a compact plate-type core design that maximizes heat rejection in a space-efficient footprint measuring 11.3 x 2.5 x 13.65 inches. The unit incorporates 1/2-inch NPT female inlet and outlet ports, providing universal compatibility with standard hose adapters and fittings common to automotive cooling systems. This aluminum construction delivers superior thermal conductivity compared to alternative materials, enabling rapid heat dissipation while maintaining structural integrity under pressure. The design is specifically engineered for automatic transmission fluid cooling applications, though experienced builders often adapt it for engine oil circuits where compact mounting and reliable performance are priorities.

Installation works best in applications where engine bay space is limited or where factory cooling is insufficient—high-horsepower builds, supercharged/turbocharged platforms, and vehicles operating in desert or trailer-towing scenarios see the greatest benefit. The lightweight 1.55-pound package integrates easily into custom plumbing systems and mounts securely using standard bracket hardware. Before installation, verify inlet and outlet port orientation relative to your system's flow direction to maximize thermal efficiency. Ensure all NPT connections are sealed with quality thread sealant or tape to prevent leaks under operating pressure, and consider a thermostat or bypass valve to maintain minimum oil temperature during cold starts.
