Detailed Description

One Stop Solutions 1553 is a premium new automotive radiator engineered to match original equipment style cooling performance for Dodge Ram diesel trucks. Core dimensions measure 36 inches high by 19 7/16 inches wide, with a 2-3/16 inch core thickness, 1 3/4 inch inlet diameter, and 1 15/16 inch outlet diameter. The unit uses a two-row core, crossflow layout, and no engine oil cooler or transmission oil cooler.

This radiator is built with premium aluminum tubes and fins, plastic tanks, and factory-spec component fitment. The design includes enhancements aimed at improving durability and cooling efficiency in higher-mileage trucks. Part number 1553 is a direct replacement choice for Ram 2500 and Ram 3500 diesel models where OE-style radiator dimensions and cooling performance are required.

This part cross-references APDI 8011553 and Spectra Premium CU1553 for the same application.

Common Cooling Problems It Can Address

• Leaking radiator tanks or seams
• Reduced cooling efficiency from an aging core
• Overheating caused by restricted or weakened radiator flow
• Heat-related stress in high-mileage diesel trucks
• Fitment issues from non-OE-style replacement radiators

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and cooler configuration before installation. This radiator is a crossflow unit and does not include a cap, engine oil cooler, or transmission oil cooler. Confirm that the vehicle is a diesel Ram 2500 or Ram 3500 from the listed model years before ordering.

For best results, inspect hoses, clamps, and mounting points during replacement so the new radiator seats correctly and seals properly.

Quality Assurance

OSC radiators are individually pressure tested during production, with testing performed before tank installation and again after final assembly. The design uses engineering updates to address common failure points and improve service life in demanding diesel truck applications.
