• Core size: 30.5 in. wide x 15 in. high x 0.63 in. thick
• Single-row core with 68 fins per 4 inches
• Inlet diameter: 1.31 in.; outlet diameter: 1.3 in.
• Outlet location: bottom right
• Internal transmission oil cooler included with adapter fittings
• Core material and dimensions support OE-style radiator replacement

Detailed Description

Global Parts 1889C radiator is engineered for vehicles that require both engine coolant heat rejection and integrated transmission cooling. The aluminum core helps dissipate heat efficiently, while the plastic tank design matches common OE-style construction used in late-1990s and early-2000s GM cooling systems. This radiator is listed for 1997-2003 Pontiac Grand Prix, 1997-2000 Oldsmobile Silhouette, 1999-2000 Pontiac Montana, 1997-1999 Buick Century, 1997-1999 Buick Regal, 1998-1999 Oldsmobile Intrigue, and 1997-1998 Cadillac Catera. The part number 1889C is also referenced in aftermarket cross listings for applications that use the same radiator configuration.

What This Radiator Helps Address

• Engine overheating caused by reduced coolant heat dissipation
• Transmission fluid temperature buildup in vehicles with an integrated cooler
• Leaks from aging radiator tanks or core seams
• Restricted cooling performance from a worn or clogged radiator core
• Replacement needs for GM vehicles with bottom-right outlet routing

Installation Notes and Tips

Verify core dimensions, inlet and outlet locations, and transmission cooler connection style before installation. This radiator uses a bottom-right outlet and adapter-style transmission oil cooler fittings, so line routing should be checked against the original unit. Confirm fitment for your specific Pontiac Grand Prix, Buick Regal, or other listed application by matching the radiator dimensions and hose connections to the OE part.

Quality Assurance

Global Parts 1889C is built as a radiator replacement for cooling-system service on the listed GM applications. It is intended to restore proper coolant flow and heat exchange performance when the original radiator is worn or damaged.
