Spectra 2001-4704P Radiator

Spectra Heavy Duty Radiator 2001-4704P

The Spectra 2001-4704P is a heavy duty radiator built for applications that need dependable engine cooling and integrated transmission fluid cooling. It uses an aluminum core with plastic tanks and a downflow design to match OE-style packaging and thermal performance requirements.

Compatible With select vehicle applications that use an upper-right inlet, lower-left outlet layout, this radiator is a direct replacement option for service work on heavy duty cooling systems. The Spectra 2001-4704P also includes a plated transmission oil cooler and mounting hardware for a more complete radiator assembly.

• Downflow flow orientation
• 2-row core construction
• Transmission oil cooler included, fan side location
• Plated transmission cooler design with 5 plates
• Core dimensions: 39 in. height, 41.25 in. width, 2.1875 in. thickness
• 2.5 in. inlet and 2.5 in. outlet diameters
• Upper right inlet and lower left outlet locations
• Mounting hardware included

Detailed Description

Built under Spectra Premium heavy duty radiator standards, the 2001-4704P is engineered to meet or exceed the performance of the original equipment radiator it replaces. The aluminum core supports efficient heat transfer, while the plastic tank construction helps maintain OE-style fit and function. The integrated transmission oil cooler adds fluid temperature control for vehicles that route transmission cooling through the radiator assembly. This part number, 2001-4704P, is a practical choice for service technicians and owners replacing a worn or leaking radiator in heavy duty cooling systems. It is also referenced by cross numbers such as HDC010843 and WES20 for the same application.

Common Problems This Radiator Can Address

• Engine overheating caused by a restricted or inefficient radiator core
• Coolant leaks from cracked tanks or aging radiator seams
• Transmission fluid temperature issues related to a failing cooler circuit
• Reduced cooling performance from damaged fins or internal blockage
• Fitment concerns when replacing an OE-style downflow radiator

Installation Notes and Tips

Verify inlet and outlet placement, core size, and transmission cooler routing before installation. This radiator uses an upper-right inlet and lower-left outlet, with the transmission oil cooler located on the fan side. Confirm that the mounting points, hose diameters, and cooler line connections match the vehicle before final assembly. The included mounting hardware supports installation, but all connections should be inspected for proper sealing and alignment during service.

Quality Assurance

Spectra Premium states that its heavy duty radiators are produced with engineering, manufacturing, and quality control processes intended to meet or exceed OE performance. The 2001-4704P is built to support reliable cooling performance in demanding applications, including engine and transmission cooling circuits.
