What engine did a 1998 Chevy 2500 have?
The 1998 Chevy 2500 could come with several engines depending on configuration: gasoline V8 options such as a 5.7-liter and a 7.4-liter, and a 6.5-liter Turbo-Diesel. The exact engine depended on trim, cab style, and bed length.
Engine options for the 1998 Chevy C/K 2500
Chevrolet’s 1998 C/K 2500 lineup offered a mix of gasoline V8s and a turbo-diesel to suit work, towing, and daily driving. Availability varied by cab configuration, bed size, and optional packages.
Gasoline engines
Gasoline-powered 2500 models used two primary V8 engines to balance power and payload, with different tuning and emissions equipment across trims:
- 5.7-liter V8 (5.7L) — a 350-cid V8 commonly used in GM trucks of the era, available across several 2500 configurations.
- 7.4-liter V8 (7.4L) — a larger 454-cid V8 offered for higher towing and payload capability.
Gasoline options provided robust power for work duties and everyday use, with the larger 7.4L delivering the strongest available performance among the gas engines.
Diesel engine
The diesel option for the 1998 2500 was the 6.5-liter Turbo-Diesel V8, a turbocharged gasoline-alternative designed for high torque and long-haul durability. This engine was a common choice for buyers prioritizing towing efficiency and longevity in demanding service.
- 6.5-liter Turbo-Diesel V8 (6.5L TD) — turbocharged diesel engine used in GM heavy-duty pickups in that era.
Diesel power appealed to customers with frequent and heavy towing needs, though maintenance and fuel costs could differ from the gasoline options.
Why engine choices vary on a 1998 model
Because the 1998 C/K 2500 line included multiple body configurations (Regular Cab, Extended Cab, different bed lengths) and trim levels, the exact engine could differ from truck to truck. Some markets and option packages also influenced which powertrain was installed. If you’re trying to identify the engine on a specific vehicle, a VIN decoding or window sticker examination will confirm the original powertrain.
Summary
For the 1998 Chevrolet C/K 2500 lineup, buyers could choose from three engine families: a 5.7-liter V8, a 7.4-liter V8, or a 6.5-liter Turbo-Diesel V8. The actual engine on a given truck depended on configuration and options, so checking the vehicle’s VIN or original window sticker is the surest way to confirm the exact powertrain.
