What are the core specifications and cooling capacity of the CU2136 Radiator?

The Spectra Premium CU2136 Radiator provides cooling capacity that meets or exceeds original equipment performance for specific Ford applications. This unit serves as a direct replacement for the factory cooling system, designed to maintain optimal operating temperatures by managing the heat generated by both the engine and transmission components. We included the CU2136 Radiator in our review because it provides a high-efficiency cooling solution for owners seeking to maintain factory specifications without aftermarket modifications.

The CU2136 Radiator features an inlet header measuring 17-3/16 inches by 3-1/16 inches and an outlet header of 17-1/2 inches by 3-1/16 inches. Because this is a complete cooling assembly—a metal heat exchanger that circulates fluid to keep an engine from overheating—the core material and flow path are engineered for maximum cooling efficiency. Since the radiator includes both engine and transmission components, it is a direct replacement for the OEM part and does not require custom modifications to the transmission cooler lines. For a complete radiator buyer, verifying these internal component integrations is vital because a mismatch in the cooling circuit can lead to localized hotspots or transmission fluid degradation. While the unit requires no modifications for fit, you must confirm the specific coolant type and capacity required by your vehicle’s service manual to ensure the core reaches its rated performance.

What to Check Before Buying the CU2136 Radiator

Before purchasing this unit, verify these specific details to ensure a proper fit and functional performance:

• Confirm that the included mounting brackets match your specific Ford trim level to prevent vibrations or leaks.
• Verify that the hose connection diameters match your existing upper and lower factory cooling lines.
• Check the engine bay to ensure the radiator height does not interfere with the cooling fan shroud or AC compressor.
• Consult the manufacturer’s compatibility page to confirm the exact coolant volume needed for this specific core.
• Confirm that the transmission cooling lines align with the included integrated components.

Comparing the CU2136 Radiator to Other Options

The CU2136 Radiator is designed for buyers who prioritize maintaining the original equipment’s cooling profile and fitment. It is a standard replacement option where the goal is to restore factory performance rather than achieve extreme gains. If you require a high-performance racing radiator for heavy-duty towing or high-output modifications, you may need to look at aftermarket units with higher core row counts or specialized materials like copper. However, for most drivers who want a reliable, direct-fit part that matches the original flow rates and pressure ratings, this unit provides the necessary specifications.
