Reliability Of 2016 Ford Explorer – A Real-World Owner’S Maintenance
The 2016 Ford Explorer offers a blend of comfort and utility, but its long-term dependability hinges on how well you manage known issues like the internal water pump and PTU service. This guide provides a deep dive into the mechanical health of this SUV, offering actionable DIY advice to help you reach the 200,000-mile mark safely.
Choosing a used mid-size SUV is a major decision that requires balancing features against potential repair bills. You likely want a vehicle that can handle the daily commute and the occasional off-road weekend without a surprise trip to the mechanic.
The reliability of 2016 Ford explorer models is a common topic among enthusiasts because this year marked a significant mid-cycle refresh. While Ford updated the styling and technology, several mechanical components remained that require a watchful eye and a proactive maintenance mindset.
In this guide, we will break down the common failure points, the best engine options, and the specific maintenance steps you can take in your own garage. Whether you are a seasoned DIYer or a first-time owner, these insights will help you navigate the ownership experience with confidence.
The Mechanical Heart: Reliability of 2016 Ford Explorer Engines
Ford offered three distinct engine options for the 2016 model year, each with its own set of pros and cons. Understanding which one sits under your hood is the first step in predicting your long-term maintenance costs and overall vehicle health.
The 3.5L Ti-VCT V6 – The Naturally Aspirated Workhorse
The base 3.5L Duratec V6 is generally considered the most reliable in terms of simple mechanical operation. It lacks the complexity of turbochargers, which means fewer vacuum lines and cooling components to fail over time.
However, this engine is famous for its internal water pump design, which we will cover in detail later. If you keep the cooling system pristine, this engine can easily surpass 200,000 miles with basic oil changes every 5,000 miles.
The 2.3L EcoBoost – Efficiency Meets Complexity
Replacing the older 2.0L EcoBoost, the 2.3L brought more power and better towing capacity to the four-cylinder lineup. It is a punchy engine, but it operates under high cylinder pressures and heat.
Owners should be diligent about using high-quality full synthetic oil to protect the turbocharger bearings. Watch for carbon buildup on the intake valves, a common trait of direct-injection engines that may require a walnut blasting service eventually.
The 3.5L EcoBoost – Performance and Power
Found in the Sport and Platinum trims, this twin-turbocharged V6 turns the Explorer into a powerhouse. While thrilling to drive, it adds two turbochargers and a more complex intercooler system to the mix.
Reliability here is good, provided you don’t skip maintenance. Heat is the enemy of these engines, so ensuring your radiator and cooling fans are functioning perfectly is non-negotiable for towing or off-road use.
The Internal Water Pump: A Critical Maintenance Check
The most significant concern regarding the reliability of 2016 Ford explorer 3.5L engines (both base and EcoBoost) is the water pump. Unlike most cars where the pump is driven by an external belt, Ford placed this one behind the timing cover.
When this pump fails, it doesn’t just leak on your driveway; it often leaks coolant into the oil pan. If this goes unnoticed, the resulting “milkshake” mixture will destroy your engine bearings in a matter of miles.
To stay safe, check your oil dipstick weekly for any signs of milky, tan-colored residue. If you see the coolant level dropping in the reservoir without a visible external leak, stop driving immediately and have the pump inspected by a professional.
Drivetrain and the “Lifetime Fluid” Myth
The 2016 Explorer uses the 6F55 six-speed automatic transmission, which is generally robust. However, the 4WD and AWD models feature a Power Transfer Unit (PTU) that is notorious for overheating and fluid breakdown.
Ford originally marketed the PTU fluid as “filled for life,” but many mechanics disagree. The PTU sits very close to the exhaust manifold, which cooks the small amount of gear oil inside until it turns into a thick, black sludge.
For better long-term reliability, I recommend changing the PTU fluid every 30,000 miles. You will need a fluid extraction pump to suck the old oil out of the fill plug, as most units do not have a dedicated drain plug.
- Tools Needed: Fluid transfer pump, 3/8-inch drive ratchet, 75W-140 synthetic gear oil.
- Safety Tip: Always perform this when the vehicle is cool to avoid burns from the nearby catalytic converter.
- Benefit: Prevents PTU bearing failure and expensive “all-wheel-drive off” warning lights.
Suspension and Steering: Keeping it Pointed Straight
A vehicle’s reliability isn’t just about the engine; it’s about staying on the road. The 2016 Explorer has faced several recalls and TSBs (Technical Service Bulletins) related to the rear suspension toe links.
If these links fracture, you can lose control of the rear steering geometry, leading to a dangerous situation. Always check your VIN on the NHTSA website to ensure all suspension-related recalls have been performed by a Ford dealer.
You should also listen for “clunking” or “popping” sounds when turning the steering wheel at low speeds. This can indicate issues with the Electronic Power Assist Steering (EPAS) rack, which is a costly component to replace if it fails completely.
Interior Tech and the Sync 3 Advantage
2016 was a transition year for Ford’s infotainment systems. Early build models may have the older Sync 2 (MyFord Touch) system, while later builds received the much-improved Sync 3 system.
Sync 3 is significantly more reliable, faster, and supports Apple CarPlay and Android Auto. If you are shopping for a 2016 model, look for the Sync 3 interface, as it suffers from far fewer software crashes and “black screen” issues.
If your screen does freeze, a common DIY fix is a “soft reset.” Hold the Power button and the Seek Up button simultaneously for about 10 seconds until the system reboots. This often clears minor glitches without a trip to the dealer.
Off-Road and Heavy Use Considerations
If you plan on taking your Explorer onto trails or using it for heavy camping trips, the Terrain Management System is your best friend. This system adjusts throttle response and braking to optimize traction in mud, sand, or snow.
However, heavy off-road use puts extra strain on the CV axles and wheel bearings. After a weekend in the dirt, always crawl underneath with a flashlight to check for torn CV boots.
A torn boot allows grease to escape and dirt to enter, which will ruin the joint quickly. Replacing a boot is a cheap DIY job; replacing an entire half-shaft axle is much more labor-intensive and expensive.
DIY Maintenance Schedule for 2016 Explorer Owners
To maximize the reliability of 2016 Ford explorer ownership, you must go beyond the “normal” service intervals suggested in the manual. High-heat environments and stop-and-go traffic qualify as “severe service.”
- Engine Oil: Every 5,000 miles using a high-quality 5W-20 or 5W-30 full synthetic and a Motorcraft filter.
- Transmission Fluid: Drain and fill every 45,000 miles. Do not do a high-pressure flush; a simple drain and fill is safer for older seals.
- PTU Gear Oil: Every 30,000 miles to prevent “sludging” and bearing failure.
- Coolant Flush: Every 60,000 miles. Fresh coolant is vital for protecting that internal water pump seal.
- Spark Plugs: Every 60,000 miles for EcoBoost engines, or 100,000 miles for the base V6.
