Is the 2000 7.3 power stroke a good engine?
Yes. The 2000 Ford 7.3 Power Stroke is widely regarded as a durable, reliable diesel engine that delivers strong torque and longevity when properly maintained.
In this article, we explore why this engine remains highly regarded, what maintenance it requires, common issues to watch for, and practical guidance for buyers considering a used 2000 model.
Why the 7.3 Power Stroke is considered durable
Below are the core strengths of the 7.3 Power Stroke that explain its enduring reputation.
- Exceptional low-end torque and proven durability: The 7.3 Power Stroke is celebrated for pulling power and a robust, time-tested design.
- Robust mechanical architecture: A heavy-duty iron block and reliable bottom end, paired with Ford’s reliable HEUI fuel system, contribute to long life with proper care.
- Strong aftermarket support: Parts, knowledge, and rebuild options are plentiful, making repairs easier and often more affordable than many modern diesels.
- Long service life with maintenance: When owners follow recommended service intervals, engines frequently reach well into the hundreds of thousands of miles.
In practice, these attributes translate to a powertrain that can handle heavy towing and daily work duties for many years when maintained thoughtfully.
Maintenance considerations and common issues
While durable, the 7.3 Power Stroke requires attentive upkeep and awareness of aging components. Here are the main maintenance points and potential trouble spots to monitor.
- Fuel system and injection: The HEUI injectors, high-pressure oil system, and the Fuel Injection Control Module (FICM) are central to performance. Symptoms of trouble can include hard starting, rough idle, or reduced power; regular checks of oil quality, filtration, and sensor health are advised.
- Oil and cooling system: Consistent oil changes with quality oil are crucial. Watch for oil cooler leaks, gasket wear around valve covers and the oil pan, and monitor coolant levels and radiator condition to prevent overheating under load.
- Turbo and intercooler: Inspect for boost leaks, cracked pipes, and worn turbo components. Adequate oil supply to the turbo is essential for long life.
- EGR and emissions hardware: EGR valves and coolers can clog over time, potentially causing overheating or reduced performance. Some owners opt to upgrade or modify emissions components to reduce maintenance needs.
- Common failure points: The FICM and ICP (injection control pressure) sensor can fail and cause starting or performance issues; wiring harnesses can become brittle with age, so inspect connectors and insulation.
- Gasket and seal wear: Expect possible oil leaks around valve covers, oil pan, and related gaskets as miles accumulate; timely attention minimizes further engine stress.
With diligent maintenance and timely part replacements, the 7.3 Power Stroke remains a dependable option. Neglect, however, can lead to expensive and harder-to-diagnose failures.
Buying a used 2000 model: what to look for
For buyers considering a used 2000 7.3 Power Stroke, a careful inspection and comprehensive service history matter more than ever. Use these guidelines to evaluate a prospective purchase.
- Service history and maintenance records: Look for regular oil changes, filter changes, and documented attention to known weak points (FICM-related repairs, oil cooler work, and sensor replacements).
- Compression and leaks: Check cylinder compression and inspect for coolant/oil leaks, head gasket integrity, and signs of overheating.
- Component wear: Inspect the fuel system components, especially the high-pressure oil system, injectors, and related sensors; verify there are no interlocks or limp-mode situations.
- Overall condition and mileage: A well-kept example with reasonable miles and up-to-date maintenance plans tends to outperform a lower-mileage truck with spotty service history.
- Cost of ownership: Be prepared for premium fuel costs, strategic maintenance, and potential expensive-but-not-uncommon repairs on aging ignition, fuel, and cooling components.
In short, a 2000 7.3 Power Stroke can be a reliable long-term workhorse if you buy with records in hand and are prepared for ongoing diesel maintenance.
Summary
The 2000 Ford 7.3 Power Stroke remains one of the most respected diesel engines Ford ever produced for pickups. Its blend of strong torque, proven durability, and broad parts support makes it a compelling choice for buyers who value reliability and the ability to tow and work hard. The trade-off is that older hardware carries maintenance needs—attention to the fuel system, oil cooler, cooling system, and emissions-related components is essential. With a thorough pre-purchase inspection and a solid maintenance history, a well-kept 2000 7.3 Power Stroke can continue to deliver dependable service for years to come.
What year to avoid a 7.3 Power Stroke?
The 7.3L Power Stroke years to avoid are generally late 2002 through 2003 because they used weaker, powdered metal rods (PMRs) instead of the stronger, forged rods found in earlier models. These PMRs are a point of concern for anyone planning to modify the engine for higher horsepower. Otherwise, all 7.3L Power Strokes are considered reliable, though the older 1994-1998 models produced less power and may have more age-related issues.

Years to be cautious about
- 2002-2003 (specifically, late 2002-2003): These years are often mentioned for their use of powdered metal rods (PMRs), which are less durable for high-performance applications. However, they are still reliable for stock use and are not necessarily a "bad" year if you don't plan on heavy modifications.
- 1994-1998: These are the oldest models and have less horsepower than later versions, which might be a drawback for some users. They are still considered reliable but are more likely to have age-related wear and tear.
Why these years?
- Powdered Metal Rods (PMRs): The main reason to avoid the late 2002-2003 model years is the switch from forged connecting rods to powdered metal rods. Forged rods are stronger and can handle more power, making PMRs a potential failure point if you plan to significantly increase horsepower.
- Lower Horsepower (1994-1998): The earliest models had less horsepower, which may not be ideal for daily driving or heavy towing compared to later models.
General considerations
- Reliability: Despite these specific concerns, the 7.3L Power Stroke is widely regarded as a very reliable engine.
- Age: All 7.3L engines are now quite old, so any model you consider will likely require maintenance and part replacements due to age, regardless of the specific year.
- Modifications: If you're planning modifications like performance tuning, staying away from PMR engines (late 2002-2003) is the most critical guideline.
What is the main problem with the 7.3 Power Stroke?
Overheating. Overheating is thought to be a common concern with the 7.3 Powerstroke engine. Numerous causes can contribute to overheating, including problems with the radiator, thermostat, water pump, cooling fan, or insufficient coolant.
Is the 2000 7.3 Power Stroke reliable?
Despite its highly-vaunted reliability, coming in only second to the 5.9-liter Cummins, the 7.3 Powerstroke did have some problems. Some of these problems were also fairly common, and they occurred in all of the production years since the overall engine was the same.
What is the life expectancy of a 2000 7.3 diesel?
Powerstroke Engine Average Life Expectancy:
7.3L400,000-500,000 miles.
