What engine does a 1989 Ford F250 have?

The 1989 Ford F-250 did not have a single engine; it offered several choices, with popular gasoline options including the 4.9 L inline-six, the 5.8 L V8, and the 7.5 L V8, plus diesel options such as the 6.9 L IDI and the 7.3 L IDI.


The following sections summarize the main engine options by fuel type and explain how to identify the exact engine in your specific truck, since the lineup varied by configuration and market.


Gasoline engines


Here are the gasoline-powered engines most frequently found in 1989 F-250s, noting that availability varied by cab/bed configuration and market.



  • 4.9 L inline-six (300 CID) gasoline engine

  • 5.8 L V8 (351W) gasoline engine

  • 7.5 L V8 (460 CID) gasoline engine


Gasoline engines in the 1989 F-250 range gave buyers a balance of towing ability and reliability, with the big-block 7.5 L V8 offering substantial low-end torque for heavy jobs.


Diesel engines


For buyers seeking torque and long-haul efficiency, the 1989 F-250 offered two diesel inline-six options.



  • 6.9 L IDI V8 diesel

  • 7.3 L IDI V8 diesel


Diesel options were favored by fleets and buyers hauling heavy loads, though they typically carried higher initial cost and maintenance considerations.


How to identify your engine


To confirm the exact engine in a specific 1989 F-250, use these steps to read the engine code and cross-check against build data.



  • Inspect the radiator-core-support/engine-code sticker under the hood for the engine code and displacement.

  • Match the code to Ford’s engine options for the 1989 F-Series using a factory manual or trusted online VIN/engine code databases.

  • Verify via the VIN: A 17-digit VIN can be used with Ford’s database or a reputable decoding service to reveal the original engine code for that truck.


Knowing the exact engine helps with parts compatibility, maintenance intervals, and proper towing capacity calculations for a classic F-250.


Summary


The 1989 Ford F-250 offered a diverse engine lineup, with gasoline options including the 4.9 L inline-six, 5.8 L V8, and 7.5 L V8, and diesel options including the 6.9 L IDI and 7.3 L IDI. The precise engine depended on the vehicle’s configuration, and owners can confirm the exact powerplant by checking the engine code on the hood area or radiator support and cross-referencing the VIN.

Which F-250 to stay away from?


You should generally avoid the 2006, 2008, 2011, and 2017 Ford F-250 models due to common issues like the "death wobble," transmission problems, and other electrical and brake failures. Other models to approach with caution include the 2003-2007 F-250 with the 6.0L Power Stroke engine due to potential engine problems, and the 2008-2010 F-250 with the 6.4L engine, which has known EGR cooler issues. 
Model years to avoid

  • 2006: Known for stalling, power steering loss, and brake issues, along with the death wobble. 
  • 2008: Has serious brake problems and the death wobble. 
  • 2011: Often experiences transmission issues, rough shifting, and the death wobble. 
  • 2017: Plagued by the "death wobble" and other suspension/steering problems. 
  • 2017-2019: Specifically mentioned as being susceptible to the "death wobble". 
  • 2003-2007 (with 6.0L Power Stroke engine): Prone to head gasket and oil cooler failures in stock form. 
  • 2008-2010 (with 6.4L Power Stroke engine): Has common EGR cooler failures that can lead to coolant loss and overheating. 

General issues to be aware of
  • Death Wobble: This is a recurring problem in several model years, especially 2008, 2011, and 2017, and is related to suspension and steering components. 
  • Transmission Problems: Rough shifting and unexpected gear changes have been reported in certain years, notably 2011. 
  • Engine Issues: Specific diesel engines have known problems. The 6.0L and 6.4L engines are especially notorious for requiring significant maintenance or bulletproofing to be reliable. 
  • Brake Failures: Some models have reported brake problems, including sudden failure and issues with the brake booster.
