2018 Ford Explorer Engine Options – A Performance And Reliability
The 2018 Ford Explorer offers three distinct powertrains tailored to different driving needs, ranging from fuel-efficient commuting to high-performance towing. This guide breaks down the capabilities, maintenance requirements, and real-world reliability of each engine choice to help you make an informed decision.
Understanding Your 2018 Ford Explorer Engine Options
Choosing the right powerplant for your SUV depends heavily on how you use your vehicle. Whether you are navigating tight city streets, hauling gear for a weekend camping trip, or looking for a bit of extra kick on the highway, Ford designed these three engines to cover a broad spectrum of driver requirements.
In this article, we will explore the technical specifications and practical trade-offs of the 2018 Ford Explorer engine options. We’ll look at everything from the base naturally aspirated unit to the high-output twin-turbocharged variant, ensuring you have the knowledge to maintain your vehicle for the long haul.
The Base Engine: 3.5L Ti-VCT V6
The entry-level choice for the 2018 model year is the tried-and-true 3.5-liter Ti-VCT V6. This engine is a workhorse, designed for simplicity and longevity rather than raw speed.
Performance and Daily Use
Producing 290 horsepower and 255 lb-ft of torque, this engine is more than capable for daily commuting and school runs. It uses Twin Independent Variable Camshaft Timing (Ti-VCT) to optimize performance across the rev range.
Because it lacks forced induction—like a turbocharger—it is generally less complex to maintain for the DIY mechanic. You will find that standard oil changes and air filter replacements are straightforward, making it an excellent choice for owners who prefer doing their own routine maintenance.
When to Choose the Base V6
- You prioritize lower long-term maintenance costs.
- Your driving is primarily urban or suburban.
- You do not need to tow heavy trailers frequently.
The Efficient Alternative: 2.3L EcoBoost I-4
For those looking to balance power with better fuel economy, the 2.3-liter EcoBoost inline-four cylinder is a compelling choice. While it is smaller than the base V6, the turbocharger allows it to punch well above its weight class.
Turbocharging Dynamics
The EcoBoost technology forces more air into the engine, allowing it to produce 280 horsepower and an impressive 310 lb-ft of torque. That extra torque is particularly helpful when merging onto the highway or passing slow-moving traffic.
However, keep in mind that turbocharged engines require strict adherence to oil change intervals. Using high-quality full synthetic oil is non-negotiable to prevent heat-related breakdown and to keep the turbocharger bearings in good health.
The Performance Choice: 3.5L EcoBoost V6
If you have an appetite for power or need to pull a heavy boat or camper, the 3.5-liter EcoBoost V6 is the engine of choice. It transforms the Explorer into a surprisingly quick machine.
Power and Towing Capability
With 365 horsepower and 350 lb-ft of torque, this engine provides a massive surge of power. It is standard on the Sport and Platinum trims, turning the SUV into a capable hauler that handles steep mountain grades with ease.
When towing, ensure your cooling system is in top shape. Regularly check your coolant levels and inspect your radiator hoses for signs of cracking or fatigue. If you plan to tow often, consider upgrading to a larger transmission cooler if you find the gearbox running consistently hot during long hauls.
Maintenance Tips for All Engine Types
Regardless of which engine you choose, consistent upkeep is the secret to a long vehicle life. Modern engines are sensitive to even minor neglect.
The Importance of Clean Air
Your engine needs to breathe. A clogged engine air filter restricts airflow, which directly impacts fuel economy and throttle response. Check your filter every 10,000 miles, especially if you live in dusty or off-road environments.
Monitoring Your Fluids
Your transmission fluid and coolant are just as important as your motor oil. If you notice your transmission shifting erratically, it is often a sign that the fluid is degraded or the level is low. Always use the manufacturer-recommended fluid specifications found in your owner’s manual to avoid internal damage.
Common Pitfalls and How to Avoid Them
Even the best engines can run into trouble if ignored. Being proactive is the best way to avoid a trip to the dealership.
- Carbon Buildup: Direct-injection engines, like the EcoBoost variants, can experience carbon deposits on intake valves over time. Using high-quality top-tier fuel helps mitigate this.
- Ignition Issues: If you feel a “stumble” or misfire under load, check your spark plugs. A failing ignition coil is a common and easy-to-fix issue for the weekend mechanic.
- Vacuum Leaks: Listen for hissing sounds under the hood. A cracked vacuum line can throw a Check Engine light and ruin your fuel efficiency.
Frequently Asked Questions About 2018 Ford Explorer Engine Options
Which engine is the most reliable for high-mileage driving?
The naturally aspirated 3.5L Ti-VCT V6 is generally considered the most reliable long-term. Its simpler design means there are fewer components—like turbos or complex intercooling systems—that can fail as the vehicle ages.
Can I use regular gas in the EcoBoost engines?
While the manual may state that regular unleaded is acceptable, these engines are designed to perform best with premium fuel. Using high-octane fuel helps prevent engine knock and allows the computer to optimize timing for better performance.
Is the 2.3L EcoBoost enough for towing?
It is capable of light-duty towing, such as a small utility trailer or a jet ski. However, if you plan on towing a travel trailer or a boat, the 3.5L EcoBoost V6 is the far superior choice due to its higher torque and robust cooling capacity.
How do I know if my turbo is failing?
Watch for signs like excessive blue smoke from the exhaust, a noticeable loss of power, or a high-pitched whining noise under acceleration. If you suspect turbo trouble, have it inspected by a professional immediately to prevent debris from damaging the rest of the engine.
Choosing your vehicle is just the first step in the journey. Whether you end up with the base V6 or the high-output EcoBoost, keeping up with your scheduled maintenance will ensure your SUV stays on the road for years to come. Stay safe, keep your tools organized, and enjoy the drive!
