What are the inlet and outlet dimensions for the RA-CCV889-3 Radiator?

The DNA Motoring RA-CCV889-3 Radiator features an inlet diameter of 1.50″ and an outlet diameter of 1.625″.

These specific port dimensions define the connection points for the cooling system. In our comparison of the radiator options we evaluated, these measurements are critical because standard hose sizes often differ from the raw port size of a high-performance unit. Because even a few millimeters of difference can prevent a leak-free seal or result in hoses that are too short, you must confirm these dimensions against your existing plumbing. The RA-CCV889-3 Radiator uses a 1/2-20UNF thread size for the transmission cooler. While the 3-row racing design provides increased heat dissipation, the port orientation and specific clearance for hose bends are not listed in the primary specifications. You should contact the manufacturer to confirm if the ports are measured to the internal thread or the external flange face to ensure a proper fit.

What to Check Before Buying the RA-CCV889-3 Radiator

Before purchasing this 3-row aluminum cooling unit, verify these technical details to ensure compatibility with your vehicle’s engine bay.

• Confirm the exact orientation of the inlet and outlet ports relative to the mounting points to ensure they are not mirrored for your specific engine layout.
• Verify if the radiator includes the necessary adapter plates or brackets for your specific hose connections.
• Measure the available clearance for hose bends once the unit is fully seated to ensure the hose geometry is not blocked by the frame.
• Check the required coolant flow direction (top-down vs. bottom-up) to avoid localized hotspots and rapid overheating.
• Confirm the transmission cooler thread size is compatible with your existing lines, as this unit uses 1/2-20UNF.

Comparing the RA-CCV889-3 Radiator to Other Options

The RA-CCV889-3 Radiator is a 3-row full aluminum radiator designed for high-performance heat dissipation. This type of heavy-duty cooling component is built for vehicles requiring more cooling capacity than stock units provide. If you have a standard cooling requirement or a very restricted engine bay, you might consider a smaller row count or a different material, as the 2.13-inch core thickness and 27.5-inch overall size require specific space. Buyers looking for a simple replacement without specialized transmission cooling may find other options that offer more standard port sizes or simpler mounting configurations.
