Detailed Product Description

The Delphi GN10139 ignition coil is engineered for vehicles that require a triple coil pack with a 6-blade male terminal layout. It is listed for 1985-1992 Buick, Oldsmobile, and Pontiac models, including Type I - Magnavox and Type II - Delco/Remy configurations where noted in the fitment data. This part number, GN10139, is a practical choice when replacing a worn ignition coil on older GM platforms that rely on module-connected coil packs.

Delphi builds aftermarket parts using OE experience and knowledge developed through long-term supplier relationships with major automakers. That background is reflected in the coil’s terminal design, interface layout, and application coverage for specific Buick LeSabre, Oldsmobile 98, and Pontiac Bonneville-era vehicles.

Common Issues This Part Can Address

• Misfire caused by weak or inconsistent spark output
• Hard starting related to ignition coil failure
• Rough idle from degraded coil performance
• Intermittent ignition breakdown in module-based systems
• Loss of spark on compatible GM ignition applications

Installation Notes and Tips

Verify the module style and connector layout before installation. This coil uses 6 male blades and is specified for systems where the blades interface with the module. Review the vehicle’s original coil and module markings, including any Type I - Magnavox or Type II - Delco/Remy notes shown in the fitment data, to confirm the correct application before replacement.

Package contents include the ignition coil and instruction sheet. For best results, inspect related ignition components and confirm all terminals are clean and properly seated during installation.
