Spectra 2001-3508P Radiator

Spectra 2001-3508P Heavy Duty Radiator

The Spectra 2001-3508P is a heavy duty radiator built for demanding cooling-system service in compatible medium- and heavy-duty applications. It combines an aluminum core with plastic tanks, a downflow layout, and an integrated transmission oil cooler to support engine and transmission temperature control.

Key Features

• Aluminum core with plastic tanks for a durable OE-style construction
• Downflow radiator design with upper left inlet and lower right outlet
• Core dimensions: 38.1875 in. height, 24.75 in. width, 2.1875 in. thickness
• 2-row core design for efficient heat transfer
• Transmission oil cooler included with plated cooler design
• Transmission oil cooler location: fan side
• Mounting hardware included
• Inlet and outlet diameter: 2.5625 in. (65 mm)

Detailed Description

Spectra Premium engineered the 2001-3508P to meet or exceed the performance of the original equipment radiator it replaces. The radiator uses welded attachment construction, a 7-plate transmission oil cooler, and a frame hardware package to support a direct replacement installation in applications that use this cooling configuration. This part cross-references Monroe Shocks & Struts (e.g., 5600) for the same application. For buyers searching for a Spectra radiator for Navistar, International, or related truck applications, the 2001-3508P is a direct-fit cooling component to verify against the original unit.

What It Helps Address

• Engine overheating caused by reduced radiator efficiency
• Transmission fluid temperature concerns in cooler-equipped systems
• Leaks or tank damage in aging radiator assemblies
• Restricted cooling performance from worn internal passages
• Replacement needs after corrosion, impact, or fatigue

Installation Notes and Tips

Confirm core dimensions, inlet and outlet location, and transmission cooler connection spacing before installation. This radiator uses a downflow configuration with the inlet at the upper left and the outlet at the lower right, so matching the original layout is important for proper fitment. Verify compatibility against the original radiator for Navistar and International truck applications before ordering. The part number 2001-3508P should be matched to the vehicle’s existing cooling-system specifications during service.

Quality Assurance

Spectra Premium states that its heavy duty radiators are manufactured with engineering, production, and quality-control processes intended to meet or exceed OE performance. The 2001-3508P is built as a replacement radiator for demanding cooling-system service and is backed by that product-level quality approach.
