Detailed Description

This OSC radiator is designed for direct replacement in Chevrolet Astro and GMC Safari vans, with fitment coverage for 1985-1986 models using a 20 3/4 inch core and 1987-1990 applications as listed. Part Number 94 uses premium tubes, fins, headers, tanks, and related components to support durability and consistent cooling performance. It is built to match original equipment cooler design where originally equipped, while incorporating engineering updates aimed at addressing common failure points in higher-mileage vehicles.

This part cross-references Four Seasons 20181 for the same application.

What It Helps Address

• Coolant leaks from worn radiator tanks, seams, or gasket surfaces
• Overheating caused by reduced heat transfer in an aging radiator core
• Transmission heat management concerns in vehicles equipped with a plated cooler
• Cooling system wear related to corrosion or internal tube deterioration
• Fitment issues from non-OE-style replacement radiators
