One Stop Solutions 1517 Radiator

Radiator for OE-Style Cooling Performance

The One Stop Solutions 1517 radiator is built for vehicles that need a direct-fit cooling replacement with OE form and function. It uses a crossflow design with a plastic tank and PA core material, plus integrated engine and transmission oil cooler provisions for applications that require both fluid circuits in one assembly.

Detailed Description

One Stop Solutions 1517 is a radiator assembly engineered for OE form and function in 1994-1996 Buick Roadmaster, Cadillac Commercial Chassis, Cadillac Fleetwood, Chevrolet Caprice, and Chevrolet Impala applications with engine oil cooler equipment. The radiator measures 30 1/2 inches in core height, 17 1/4 inches in core width, and 1-1/4 inches in core thickness, with 18 3/4-inch inlet and outlet header lengths. It also uses 2 7/16-inch header widths and 11 1/2-inch cooler fitting spacing.

This radiator includes both engine and transmission oil cooler provisions, with a concentric engine oil cooler and a plated transmission oil cooler. OSC-style engineering focuses on fit, leak resistance, and durability through premium-grade components, fitted and torqued assemblies, and repeated pressure testing. This part cross-references Spectra Premium CU1517 and APDI 8011517 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or fatigued radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature issues related to a failing cooler circuit
• Engine oil cooling concerns on vehicles equipped with an oil cooler
• Fitment problems from a damaged or incorrect replacement radiator

Installation Notes and Tips

Verify the core dimensions, inlet and outlet sizes, and cooler configuration before installation. This radiator is a drop-in style replacement for the listed applications, but the vehicle must match the w/EOC configuration shown in the fitment data. Inspect hoses, clamps, and mounting points for wear before transferring the new radiator into place.

Quality Assurance

One Stop Solutions states that each radiator is individually pressure tested, with cooler circuits checked before tank installation and again after final assembly. The design also follows OE-style cooler layouts where originally equipped, with engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
