Where the CU2136 Radiator Fits
The Spectra Premium CU2136 Radiator is for Ford owners who need a direct replacement that meets or exceeds original equipment performance as a complete radiator kit.

The Spectra Premium CU2136 Radiator addresses these fitment concerns by requiring no modifications for fit. It features an inlet header of 17-3/16 Inch x 3-1/16 Inch and an outlet header of 17-1/2 Inch x 3-1/16 Inch to ensure a proper seal.

- Pro: Features a 17-3/16 inch x 3-1/16 inch inlet header.
- Con: The 17-1/2 inch x 3-1/16 inch outlet header requires specific clearance that may not fit custom high-performance fan shrouds.

Performance: What the Specs Deliver
Dual Component Cooling
The CU2136 Radiator includes both engine and transmission components to manage heat across the entire powertrain. This dual-component design allows you to maintain consistent operating temperatures when the vehicle is under heavy loads, such as high-heat towing or heavy-duty hauling. Because it addresses both heat sources simultaneously, the unit prevents the transmission from overheating during sustained high-torque tasks.
Direct Fitment Design
The CU2136 Radiator features an inlet header of 17-3/16 inches by 3-1/16 inches and an outlet header of 17-1/2 inches by 3-1/16 inches. These specific dimensions ensure the unit fits without modifications, meaning you can replace the original unit without having to re-route lines or adjust mounting points. Before ordering, you must confirm your vehicle’s hose connection diameters match these header specifications to ensure a proper seal.
OEM Performance Standards
The Spectra Premium CU2136 Radiator meets or exceeds original equipment performance. For a buyer, this means the cooling capacity matches or exceeds the factory baseline for standard driving and load conditions. Since it is designed to meet these standards, you can rely on the unit to provide the same flow rates and pressure ratings as the factory equipment while offering maximum cooling efficiency.
