By the end of this article, you will know which configuration suits your lifestyle and how to keep it running for another hundred thousand miles. Whether you are a weekend warrior or a daily commuter, understanding these powertrains is the first step toward automotive peace of mind.
Understanding the ford explorer engine options 2017
The 2017 model year was a pivotal time for the Explorer, as Ford refined its “EcoBoost” strategy while keeping a traditional naturally aspirated option for the purists. Each of the ford explorer engine options 2017 provides a different driving character and mechanical footprint.
For the average owner, the choice usually boils down to three specific needs: efficiency, simplicity, or raw power. The 2.3L I-4 EcoBoost replaced the older 2.0L, offering a significant bump in capability. Meanwhile, the 3.5L “Cyclone” V6 remained the workhorse for fleet vehicles and base trims.
At the top of the food chain sits the 3.5L Twin-Turbo EcoBoost, an engine that turned the Explorer into a sleeper performance SUV. Understanding these choices requires looking past the window sticker and into the mechanical architecture of the blocks themselves.
The 2.3L EcoBoost Inline-4: The Efficient All-Rounder
The 2.3L EcoBoost is a marvel of modern engineering, utilizing a twin-scroll turbocharger to provide quick throttle response. It produces 280 horsepower and 310 lb-ft of torque, which is impressive for an engine of this displacement. This engine is commonly found in the Base, XLT, and Limited trims.
One of the primary benefits of this engine is its balance. It offers better fuel economy than the larger V6 while providing more low-end torque. This makes it ideal for highway cruising and light-duty family hauling where fuel efficiency is a top priority.
However, DIYers should be aware that this is a direct-injection engine. Over time, these engines can suffer from carbon buildup on the intake valves. Because fuel does not wash over the valves, oil vapor can bake onto them, potentially causing a rough idle or loss of power as the miles climb.
The 3.5L Ti-VCT V6: The Naturally Aspirated Workhorse
If you prefer simplicity and long-term durability, the 3.5L Ti-VCT (Twin Independent Variable Camshaft Timing) V6 is likely your best bet. It delivers 290 horsepower and 255 lb-ft of torque. Unlike its EcoBoost siblings, it lacks a turbocharger, meaning there are fewer components to fail under the hood.
This engine is a favorite among those who plan to keep their vehicles for over 200,000 miles. The power delivery is linear and predictable, which is great for daily driving. It is the standard engine for many ford explorer engine options 2017 configurations, particularly in the lower trim levels.
The biggest trade-off here is the torque. You have to rev this engine higher to get it moving, especially when the vehicle is fully loaded. It also lacks the “punchy” feel of the turbocharged variants, which might feel a bit sluggish during high-speed passing maneuvers on the interstate.
The 3.5L Twin-Turbo EcoBoost: The Performance King
Reserved for the Sport and Platinum trims, the 3.5L Twin-Turbo EcoBoost V6 is a beast. With 365 horsepower and 350 lb-ft of torque, it transforms the Explorer into a much faster machine. This engine is essentially a detuned version of what you might find in a Ford F-150 or even the Taurus SHO.
This engine utilizes two small turbochargers to virtually eliminate turbo lag. It provides effortless acceleration, making it the clear choice for anyone who frequently tows trailers or lives in mountainous regions. When you put your foot down, the response is immediate and authoritative.
The downside is, of course, fuel consumption and complexity. With two turbos, more vacuum lines, and a more complex cooling system, maintenance costs can be higher. It is a “pay to play” scenario where you trade operating costs for superior performance and towing capability.
Mechanical Deep Dive: Maintenance and Common Issues
Every engine has its quirks, and the ford explorer engine options 2017 are no exception. Knowing what to look for can save you thousands in “preventative” versus “reactive” repairs. As a DIYer, your best tool is a high-quality OBD-II scanner and a keen ear for unusual noises.
One of the most discussed issues with the 3.5L naturally aspirated V6 is the internal water pump. Unlike most engines where the water pump is driven by an external belt, this one is driven by the timing chain. If the pump seal fails, it can leak coolant directly into the oil pan.
If you notice your oil looking like “chocolate milk” on the dipstick, stop driving immediately. This design makes the water pump a labor-intensive repair, often requiring the engine to be partially disassembled or even removed. It is a critical check-point for any high-mileage 2017 Explorer.
Turbocharger Care for EcoBoost Engines
For those opting for the 2.3L or 3.5L EcoBoost, turbocharger health is paramount. Turbos rely on clean oil for cooling and lubrication. Using a high-quality full synthetic oil and sticking to a strict 5,000-mile change interval is the best way to prevent premature turbo failure.
Listen for a high-pitched “dentist drill” whine or look for blue smoke from the exhaust. These are signs that the turbo bearings or seals are failing. Additionally, always let the engine idle for 30-60 seconds after a long highway run to allow the turbos to cool down before shutting off the oil flow.
The Importance of PTU Fluid Changes
While not strictly an engine component, the Power Transfer Unit (PTU) is bolted to the transmission and is vital for AWD models. In the 2017 Explorer, the PTU holds a very small amount of gear oil that gets extremely hot. Ford often labeled this as a “lifetime fluid,” but many enthusiasts disagree.
Experienced mechanics recommend changing the PTU fluid every 30,000 miles. If the fluid breaks down, it turns into a thick sludge, eventually causing the unit to seize. This is a common failure point that can be avoided with a relatively simple fluid extraction and refill process.
Towing and Real-World Capability
When comparing ford explorer engine options 2017, towing capacity is often the deciding factor for outdoor enthusiasts. Not all engines are created equal when there is a boat or a camper hooked to the back. Your choice here determines how much “headroom” you have on the road.
The 3.5L Ti-VCT V6 and the 3.5L EcoBoost are both rated for a maximum towing capacity of 5,000 lbs when properly equipped with the Class III Towing Package. However, the driving experience between the two is vastly different. The EcoBoost’s torque makes pulling a trailer up a grade much less stressful.
The 2.3L EcoBoost is generally rated lower, usually around 3,000 lbs. While it has the torque to move a load, the cooling capacity and frame integration for this specific powertrain are optimized for lighter duty. If you plan on regular towing, always aim for the V6 options to ensure longevity.
- 3.5L EcoBoost: Best for heavy towing and mountain passes.
- 3.5L Ti-VCT: Reliable for occasional towing of light trailers or jet skis.
- 2.3L EcoBoost: Perfect for bike racks, small utility trailers, or hitch-mounted cargo carriers.
Safety and Decision Points for the DIY Buyer
If you are inspecting a 2017 Explorer on the used market, there are several “red flags” to watch for. Start the engine from a cold state and listen for timing chain rattle. A momentary rattle on startup could indicate a stretched chain or a failing tensioner, which is a common issue on high-mileage EcoBoost units.
Check the “weep hole” on the side of the engine block for the 3.5L V6. If you see traces of dried coolant (usually orange or pink), the internal water pump is starting to fail. This is a major negotiating point or a reason to walk away from the deal entirely.
Always verify the service history. Engines that have seen frequent oil changes are far less likely to have issues with variable valve timing solenoids or turbocharger oil feed lines. A well-documented maintenance log is worth its weight in gold when dealing with modern, high-tech powertrains.
