Spectra 2001-1778P Radiator

Spectra 2001-1778P Heavy Duty Radiator

The Spectra 2001-1778P radiator is built for heavy-duty cooling performance with an aluminum core, plastic tanks, and an integrated plated transmission oil cooler. It is engineered to meet or exceed original equipment performance for engine and transmission cooling in demanding applications.

Compatible With select vehicle applications that use a downflow radiator layout, upper right inlet, lower left outlet, and engine-side transmission cooler routing. This part number, 2001-1778P, is a direct-fit style replacement for service work where OE-style dimensions and hose connections matter.

Key Features

• Aluminum core with plastic tank construction
• Downflow design for OE-style cooling system layout
• Integrated transmission oil cooler with plated cooler section
• Core dimensions: 27.5 in. height, 25.5 in. width, 1.875 in. thickness
• 2-row core design for efficient heat transfer
• 2 in. inlet and 2 in. outlet diameters
• Upper right inlet and lower left outlet locations
• Mounting hardware included
• Pin attachment method

Detailed Description

Spectra Premium heavy duty radiators are manufactured with engineering, production controls, and quality checks aimed at matching OE cooling performance. The 2001-1778P radiator includes an engine-side transmission oil cooler, making it a practical replacement when the original radiator also handles automatic transmission fluid cooling. Its 7-plate cooler design and 18 in. fitting spacing support proper fluid routing in the cooling system.

With a 698 mm x 648 mm core size and 48 mm thickness, this radiator is built around common OE-style packaging requirements. The Spectra 2001-1778P is a strong fitment-focused choice for radiator replacement jobs where the original unit uses the same inlet, outlet, and downflow configuration. If you are servicing a vehicle application such as a Ford F-Series or similar heavy-duty truck platform, verify the radiator dimensions and cooler layout against the original unit before installation.

This part cross-references Perfection 800133 for the same application.

What It Helps Address

• Engine overheating caused by a failing radiator core
• Transmission fluid temperature issues tied to a damaged cooler circuit
• Coolant leaks from cracked plastic tanks or worn seams
• Restricted coolant flow from internal radiator deterioration
• Cooling system service needs on OE-style downflow radiator setups

Installation Notes and Tips

Confirm core height, width, thickness, inlet and outlet locations, and transmission cooler routing before installation. This radiator uses a pin attachment method and includes M6 Uclips for the listed mounting setup. Transfer or inspect related cooling system components, flush the system, and verify hose fitment and cooler line alignment during installation. The Spectra 2001-1778P is intended for applications that match the original radiator configuration, including compatible Ford F-Series and other heavy-duty truck fitments where specified.

Quality Assurance

Spectra Premium states that its heavy duty radiators are built to meet or exceed the performance of the original equipment they replace, including engine and transmission cooling components. The 2001-1778P reflects that OE-focused manufacturing approach for service replacement use.
