Detailed Description

OSC Premium New Automotive Radiator Part Number 1694 is designed for direct replacement use in select Chevrolet Suburban and GMC Suburban applications from 1994-1995. The radiator uses premium-grade materials and a multi-fit engineering approach while maintaining the original appearance and mounting layout. It includes plated engine and transmission oil cooler sections, and the cooler design follows the original equipment configuration where those features were factory equipped.

This radiator measures 18 1/2 in. across both the inlet and outlet header lengths, with 3 3/16 in. header widths, a 1 5/16 in. inlet diameter, and a 1 9/16 in. outlet diameter. The core uses PA material and a 2-row layout to support cooling performance in higher-mileage trucks and SUVs. This part cross-references Spectra Premium CU624 for the same application.

What It Helps Address

• Overheating caused by a worn or restricted radiator core
• Leaks from aging tanks, seams, or cooler interfaces
• Reduced cooling efficiency in high-mileage Chevrolet Suburban and GMC Suburban vehicles
• Transmission temperature concerns tied to a failing integrated cooler
• Engine oil cooler issues related to damaged or corroded cooler passages

Installation Notes and Tips

Verify radiator dimensions, cooler style, and hose connections before installation. This unit is built for 1994-1995 Chevrolet C1500 Suburban, C2500 Suburban, K1500 Suburban, K2500 Suburban, and the corresponding GMC Suburban applications listed above. The cap is not included, so reuse or replace the cap as needed based on the vehicle’s original setup.

For best results, flush the cooling system, inspect hoses and clamps, and confirm that the transmission and engine oil cooler lines are clean before connecting the new radiator. Part Number 1694 is intended to provide a drop-in style replacement when the vehicle matches the listed configuration.

Quality Assurance

OSC states that each radiator is pressure tested during production, with cooler testing performed before installation into the tank and again after final assembly. The design also incorporates engineering updates aimed at addressing common original-design failure points and improving durability in demanding service.
