Spectra 2001-1720P Radiator

Spectra 2001-1720P Heavy Duty Radiator

The Spectra 2001-1720P radiator is a direct-fit cooling system replacement built with an aluminum core and plastic tanks. It is engineered to meet or exceed original equipment performance for heavy-duty cooling, with integrated transmission oil cooler support for vehicles that rely on radiator-based fluid cooling.

Compatible With applications that use a downflow radiator layout, upper-left inlet, lower-right outlet, and 2-inch inlet and outlet connections. This radiator is a practical OE-style replacement for select vehicle cooling systems where stable engine temperature and transmission fluid control are critical.

Key Features

• Aluminum core with plastic tank construction
• Downflow flow orientation for OE-style cooling layout
• Core dimensions: 27.3125 in. height, 25.125 in. width, 2.1875 in. thickness
• 2-row core design for heat transfer support
• Transmission oil cooler included with plated cooler design
• Transmission oil cooler location: fan side
• Upper-left inlet and lower-right outlet configuration
• 2-inch inlet and outlet diameters
• Pin attachment method

Detailed Description

Built under the Spectra Premium heavy-duty radiator program, the 2001-1720P is manufactured with controlled engineering and quality checks to match OE cooling performance. The radiator includes a transmission oil cooler with 7 plates and 18-inch fitting spacing, making it suitable for vehicles that route automatic transmission fluid through the radiator for temperature management. This part cross-references Monroe Shocks & Struts (e.g., 5779) for the same application.

For buyers searching for a radiator for heavy-duty truck cooling, an aluminum core radiator with plastic tanks, or a replacement radiator with integrated transmission cooler, the Spectra 2001-1720P offers the core dimensions and connection layout needed for a direct replacement. It is also a relevant choice for select BBB Industries 8254 interchange applications.

Common Problems This Radiator Can Address

• Engine overheating caused by a restricted or leaking radiator
• Transmission fluid temperature issues tied to a failing radiator cooler
• Coolant loss from cracked tanks or worn core seams
• Poor heat rejection from an aging 2-row radiator assembly
• Fitment issues when replacing a radiator with the same inlet and outlet layout

Installation Notes and Tips

Verify core height, width, thickness, inlet and outlet diameter, and inlet/outlet location before installation. Confirm that the vehicle uses a downflow radiator with an upper-left inlet and lower-right outlet, and check that the transmission oil cooler connection spacing matches the existing setup. Because the frame, cap, and fan are not included, reuse or source those components separately as needed.

Quality Assurance

Spectra Premium states that its heavy-duty radiators are engineered and quality-controlled to meet or exceed the performance of the original equipment they replace. The 2001-1720P follows that OE-replacement standard for cooling performance and transmission fluid cooling support.
