One Stop Solutions 951 Radiator

Radiator for Camaro and Firebird Applications

One Stop Solutions 951 is an OSC Premium New Automotive Radiator built for OE-style form and function. It uses premium-grade aluminum construction with plastic tanks, a crossflow design, and a concentric transmission oil cooler to support cooling performance in select Chevrolet Camaro, Pontiac Firebird, and Chevrolet P20/P30 applications.

Key Features

• Core dimensions: 26 1/4 in. height, 17 1/4 in. width, and 1-1/4 in. thickness
• Crossflow radiator design with one core row
• Transmission oil cooler included; engine oil cooler not included
• Inlet diameter: 1 5/16 in.; outlet diameter: 1 9/16 in.
• Concentric transmission cooler with 1 1/4 in. diameter and 11 1/2 in. fitting spacing
• Die-cut gasket design for leak resistance
• Individually pressure tested during production
• Factory-style fitment with necessary fittings or hardware included in each unit

Detailed Description

This radiator is engineered for OE performance and direct replacement fitment in vehicles such as the 1990-1992 Chevrolet Camaro, 1982-1992 Pontiac Firebird, and select Chevrolet P20/P30 models. Part number 951 is built with upgraded cooling components, including enhanced fins, tubes, headers, and tanks, to address heat load and durability concerns in higher-mileage vehicles. The design follows original cooler architecture where equipped, using a concentric transmission cooler rather than substituting a different cooler style.

This part cross-references Spectra Premium CU750 for the same application.

What It Helps Address

• Overheating caused by a worn or restricted radiator core
• Transmission temperature issues related to a failing integrated cooler
• Coolant leaks from aged tanks, headers, or gasket surfaces
• Reduced cooling efficiency from damaged fins or internal tube wear
• Fitment problems from non-OE-style replacement radiators

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler layout before installation. This radiator is a crossflow design and should be matched to the original cooling configuration for the vehicle. Confirm the transmission cooler connection spacing and hose routing on 1982-1992 Camaro and Firebird applications, as well as the listed P20 and P30 models, before final assembly.

Quality Assurance

OSC radiators are produced with pressure testing during manufacturing, including testing of the cooler circuits before tank installation, core testing before assembly, and a final assembled-unit test. Part number 951 is engineered to meet OE-style cooler design requirements where originally equipped.
