Who makes the 3.0 Duratec engine?
The 3.0 Duratec engine is produced by Ford Motor Company, developed in collaboration with Mazda as part of the Duratec/MZR family.
Origins and development
The Duratec family replaced Ford's Zetec line in the early 2000s. The 3.0-liter version, often referred to as Duratec 30, is a 60-degree V6 designed for mid-size cars and SUVs. It was developed by Ford with Mazda cooperation; the MZR designation was used by Mazda for the same family of engines. This collaboration helped standardize the 3.0-liter V6 across multiple platforms and markets.
Key players and collaboration involved in making the 3.0 Duratec and the nature of the partnership:
- Ford Motor Company: primary developer and manufacturer of the Duratec 30 V6.
- Mazda Motor Corporation: co-developer and contributor to the Duratec/MZR family as part of the Ford-Mazda collaboration.
- Duratec/MZR lineage: the engine sits within a family designed for lightweight, efficient V6 performance across Ford and Mazda models.
The Ford-Mazda partnership led to shared engineering, components, and manufacturing networks that extended to several markets, helping standardize the 3.0-liter V6 across different platforms.
Design, specifications, and performance
As with many engine families, variations exist by model year and application. The 3.0 Duratec is a 3.0-liter V6 with a DOHC, 24-valve layout and aluminum construction, designed to balance power and efficiency for mid-size vehicles.
- Displacement: 3.0 liters (approximately 2967–2970 cc).
- Configuration: 60-degree V6.
- Valvetrain: DOHC with 24 valves (4 per cylinder).
- Materials: Aluminum block and heads to reduce weight.
- Fuel system: Sequential multipoint fuel injection.
- Power output: Typically around 200–240 horsepower, depending on application and tuning; torque generally in the 200–230 lb-ft range.
- Fuel economy and emissions: Aimed at a balance of performance with efficiency and emissions compliance across markets.
These design traits made the Duratec 30 a common choice for mid-size Ford products in the 2000s, though later models shifted toward EcoBoost or other powertrains.
Applications and current status
Where the 3.0 Duratec appeared and whether it remains in production vary by market. The engine powered a range of Ford and Mazda vehicles during its peak years and has since been phased out in most new designs in favor of newer powertrains.
- Ford models across Europe and North America during the 2000s, using the 3.0 Duratec V6 in various mid-size cars and crossovers.
- Mazda models in the corresponding MZR Duratec lineup, utilizing the 3.0 V6 variant as part of the shared engine family.
- Current status: largely discontinued in new cars; existing vehicles with the 3.0 Duratec remain on the road and in used markets. Ford has continued to shift toward EcoBoost engines for most recent models.
In short, the Duratec 30 represented a Ford-Mazda collaborative effort to provide a capable V6 for mid-size vehicles, with production and deployment largely retired from new-vehicle lineups, though legacy examples persist in the market.
Summary
The 3.0 Duratec engine is a joint Ford-Mazda design, part of the Duratec/MZR family, produced by Ford with Mazda involvement. It served as a versatile V6 option in 2000s-era Ford and Mazda models and has since been largely replaced in new designs by newer powertrains, though it remains present in older vehicles and used markets. For enthusiasts and owners, it stands as a hallmark of the Ford-Mazda collaboration during that era.

Is the Ford Duratec a good engine?
Yes, Duratec engines are generally considered good and very reliable, especially the older, naturally aspirated versions, known for their durability and longevity. However, certain models have specific issues, such as potential coolant consumption in the 2.5L or oil leaks in the 3.0L, so regular maintenance like checking coolant and oil levels is crucial.

Strengths
- Reliability and durability: Many versions of the Duratec engine are praised for being "bulletproof" and can last over 250,000 miles with proper care.
- Efficiency: The 2.5L in particular was noted for its efficiency, with the hybrid version achieving up to 38 mpg.
- Simple design: They are often considered a more straightforward and dependable alternative to more complex engines like the EcoBoost.

Potential weaknesses
- Coolant consumption: Some versions, especially the 2.5L, may consume coolant at a higher rate due to a porous engine block. This requires periodic top-offs to prevent overheating.
- Oil leaks: The 3.0L V6 is prone to oil leaks from the T-joints and bed plate, which are generally considered an easy fix.
- Water pump failure: The water pump on the 3.5L V6 can fail prematurely, sometimes between 70,000 and 140,000 miles.
Conclusion
If you are considering a vehicle with a Duratec engine, it is a good choice for reliability, but be aware of potential issues. Keeping up with maintenance, such as checking your coolant and oil levels regularly, is the best way to ensure a long life for these engines.
Which Ford engine to stay away from?
Ford engines to avoid include the 6.0L and 6.4L Power Stroke diesels, which had numerous issues like EGR cooler failures and injector problems, and the 5.4L Triton V8 known for spark plug and timing chain problems. Other engines to be cautious of are the 3.8L V6 due to head gasket failures and certain EcoBoost engines, especially early 1.0L and 1.6L models, which have faced issues like premature timing belt wear and overheating.
