What It Helps Fix

• Coolant loss from cracked tanks or weakened seams
• Reduced heat transfer from clogged or aged radiator cores
• Fitment problems from non-OE replacement radiators

Installation Notes and Tips

Verify the vehicle’s radiator dimensions, inlet and outlet sizes, and transmission cooler layout before installation. This radiator is specified for 1987-1990 Chevrolet Caprice models with a 26 1/4-inch core and standard transmission oil cooler setup. Confirm hose routing, mounting points, and cooler line connection spacing match the original system before final assembly.

Quality Assurance

OSC tests the transmission and engine oil cooler circuits before tank installation, checks the core prior to assembly, and tests the completed radiator again after assembly. The result is a production process focused on leak control, cooling performance, and OE-style fitment consistency.
