Detailed Description

Part number 888 is built for direct replacement service on Chevrolet S10 and S10 Blazer, GMC S15 and S15 Jimmy, and GMC Sonoma models listed in the fitment data. OSC-style engineering focuses on factory-style fit, cooling performance, and durability, with premium tubes, fins, headers, and tanks selected to support long-term use. The radiator is designed for applications that use an engine oil cooler and for versions originally equipped without an engine oil cooler, depending on the vehicle listing. This part cross-references APDI 8010741 and Four Seasons 20117 for the same application.

Common Problems This Radiator Addresses

• Coolant leaks from aged tanks, seams, or gasket surfaces
• Overheating caused by restricted or weakened radiator cores
• Reduced cooling efficiency in higher-mileage Chevrolet S10 and GMC S15 platforms
• Oil cooler-related heat management issues on equipped vehicles
• Fitment problems from worn or damaged original radiator assemblies

Installation Notes and Tips

Verify the vehicle’s original cooling configuration before installation, especially engine oil cooler and non-oil-cooler applications. Confirm inlet and outlet sizing, header dimensions, and core thickness against the removed unit. The radiator is engineered for multi-fit use, but the correct application should be matched to the exact year, make, model, and cooling setup listed below.

Quality Assurance

Each radiator is pressure tested during production, with cooler testing performed before tank installation and again after final assembly. The design also incorporates enhancements such as increased fin density and a thicker core to address common failure points seen in higher-mileage vehicles.
