Detailed Description

This OSC radiator is built to match OE form and function for the Chevrolet S10, Blazer, Sonoma, and Isuzu Hombre platform. Part number 1825 uses a crossflow layout, plastic tanks, and a one-row core with an integrated plated engine oil cooler. The radiator is engineered with fitted components and factory-spec torque procedures, and the design includes a die-cut gasket to help maintain a secure seal. OSC also uses premium-grade tubes, fins, headers, tanks, and related components to improve durability and cooling performance in high-mileage service.

The unit is individually pressure tested and checked multiple times during production, including testing of the oil coolers before tank installation, core testing before assembly, and a final assembled test. This part cross-references Spectra Premium CU1825 and Four Seasons 56011 for the same application.

Common Replacement Reasons

• Leaking radiator tanks or seams
• Restricted cooling performance from age or internal wear
• Failed engine oil cooler section
• Cracked or deteriorated plastic end tanks
• Overheating concerns on high-mileage Chevrolet S10, Blazer, Sonoma, or Isuzu Hombre vehicles
