Comprehensive Overview of the ford explorer 2016
The 2016 model year marked a significant “refresh” for the fifth-generation Explorer, introducing updated styling and the 2.3L EcoBoost engine. It was designed to offer better fuel efficiency without sacrificing the towing capacity or the interior room that owners expect from the nameplate.
Structurally, this vehicle utilizes a unibody construction, which provides a more car-like handling experience compared to older body-on-frame models. This makes it an excellent candidate for long-distance road trips, though it requires specific attention to its independent suspension components to maintain ride quality.
Whether you have the Base, XLT, Limited, Sport, or Platinum trim, the core architecture remains similar. Understanding the layout of your engine bay and the location of critical service points is the first step for any DIY mechanic or enthusiast.
Engine Options and Performance Specs
The standard 3.5L Ti-VCT V6 is a workhorse known for its linear power delivery and relative simplicity. It produces 290 horsepower and is often favored by those who prefer naturally aspirated engines for their long-term predictability and ease of maintenance.
The 2.3L EcoBoost four-cylinder replaced the older 2.0L version, offering 280 horsepower and significantly more torque. This engine uses gasoline direct injection and turbocharging, which requires high-quality fuel and frequent oil changes to prevent carbon buildup on the intake valves.
For those seeking maximum performance, the 3.5L Twin-Turbo EcoBoost V6 in the Sport and Platinum trims delivers 365 horsepower. This powerhouse turns the SUV into a formidable highway cruiser but demands strict adherence to cooling system maintenance due to the extra heat generated by the turbos.
Essential Maintenance Schedule and DIY Fluid Changes
Regular fluid changes are the cheapest insurance policy you can buy for your vehicle. While the owner’s manual suggests long intervals, experienced technicians recommend more frequent services, especially if you engage in heavy towing or stop-and-go city driving.
Engine oil should be changed every 5,000 to 7,500 miles using a high-quality full synthetic oil. This is particularly critical for EcoBoost engines, where the oil also serves to lubricate and cool the turbocharger bearings at high RPMs.
Don’t forget the transmission fluid; the 6F55 and 6F50 6-speed automatics benefit greatly from a “drain and fill” every 30,000 to 50,000 miles. Avoid a high-pressure flush if the fluid is already dark, as this can sometimes dislodge clutch debris and cause shifting issues.
Step-by-Step Oil Change Guide
- Warm up the engine slightly to help the oil flow, then secure the vehicle on jack stands or ramps.
- Locate the oil drain plug on the bottom of the oil pan and place a catch basin underneath.
- Remove the plug with a 15mm wrench and let the old oil drain completely into the pan.
- Replace the oil filter, making sure to lubricate the new rubber gasket with a drop of fresh oil.
- Reinstall the drain plug with a new crush washer and refill the engine with the recommended volume of 5W-30 or 5W-20 oil.
The Power Transfer Unit (PTU) Service
If you have an Intelligent 4WD model, the PTU is a critical component that transfers power to the rear wheels. It holds a very small amount of gear lube and is positioned near the hot exhaust, which can cause the fluid to “cook” and turn into a thick sludge.
Many ford explorer 2016 owners choose to replace this fluid every 30,000 miles to prevent internal gear failure. Since many units lack a drain plug, you may need a suction pump to extract the old fluid through the fill hole before pumping in fresh 75W-140 synthetic gear oil.
Troubleshooting Common Mechanical Issues and Fault Codes
Every vehicle has its “Achilles’ heel,” and for this era of Explorer, there are a few well-documented areas that require vigilance. Being proactive about these issues can prevent a breakdown on the side of the road or a costly repair bill at the dealership.
One of the most discussed issues is the internal water pump on the 3.5L V6 engines. Because the pump is driven by the timing chain inside the engine, a leak can allow coolant to mix with the engine oil, which can lead to catastrophic engine failure if not caught early.
Watch for signs of “milky” oil on the dipstick or a disappearing coolant level without visible external leaks. If you notice these symptoms, stop driving immediately and consult a certified master technician, as this repair requires extensive engine teardown.
Suspension and Steering Concerns
The rear suspension toe links have been a subject of several recalls due to their tendency to fracture under stress. A broken toe link can cause a sudden loss of steering control, which is a major safety risk, especially at highway speeds.
Listen for unusual clunking or rattling sounds coming from the rear when driving over bumps. If your vehicle feels “loose” or wanders in the lane, have a shop inspect the bushings and links immediately to ensure your chassis is stable.
The electronic power assist steering (EPAS) can also experience glitches, often manifesting as a “Steering Assist Fault” message on the dash. Often, this is caused by a low-voltage battery or a faulty sensor, but it sometimes requires the replacement of the entire steering rack.
Addressing Carbon Buildup
Direct-injection engines like the EcoBoost are prone to carbon deposits on the intake valves because fuel no longer “washes” the valves clean. This can lead to a rough idle, decreased fuel economy, and a loss of top-end power over time.
Using an intake valve cleaner spray every 10,000 miles can help mitigate this buildup. Additionally, installing a catch can in the PCV system can trap oil vapors before they reach the intake, keeping your engine breathing clearly.
Performance Modifications and Off-Road Setup
While it is primarily a family hauler, the 2016 Explorer can be modified to handle light-to-moderate off-road trails. The Terrain Management System is quite capable, but it is often limited by the factory street tires and low ground clearance.
The first upgrade for any off-roader should be a set of all-terrain tires. Look for a tire with a reinforced sidewall and a tread pattern that can clear mud and grip loose gravel without creating excessive road noise on the highway.
If you plan on hitting technical trails, consider a 1.5-inch to 2-inch leveling kit. This provides a bit more clearance for the front air dam and allows for slightly larger tires, giving the vehicle a more aggressive stance and better approach angles.
Essential Off-Road Gear
- Portable Air Compressor: Vital for airing down your tires for traction and airing back up for the drive home.
- Recovery Straps: Never hit the trail without a high-quality kinetic recovery rope and rated D-rings.
- Skid Plates: If you find yourself in rocky terrain, aftermarket underbody protection can save your oil pan and transmission.
- LED Lighting: Upgrading the factory fog lights or adding a discreet light bar can significantly improve visibility during night-time trail runs.
Tuning for Power
For those with the EcoBoost engines, an aftermarket tune can unlock significant horsepower and torque. By optimizing the boost pressure and ignition timing, these tuners make the vehicle feel much lighter on its feet and improve throttle response.
Always pair a tune with a high-quality air intake and perhaps an upgraded intercooler to keep the charge air temperatures low. Be aware that aggressive tuning can put more stress on the drivetrain, so stay on top of your fluid changes.
Comparison of Engine Options: 2.3L EcoBoost vs. 3.5L V6
Choosing between the two primary engines in the ford explorer 2016 depends largely on your driving habits. The 2.3L EcoBoost is the choice for the tech-forward driver who wants torque-rich performance and better fuel economy during city driving.
The 3.5L V6 is the “old school” choice, offering a simpler mechanical design that many DIYers find easier to work on. It lacks the turbo lag of the EcoBoost and generally has a more predictable power band for towing small trailers or boats.
In terms of longevity, the 3.5L V6 has fewer components that can fail, such as turbo wastegates or intercooler piping. However, the 2.3L EcoBoost provides a more modern driving experience and better low-end grunt for merging onto busy highways.
| Feature | 2.3L EcoBoost | 3.5L Ti-VCT V6 |
|---|---|---|
| Horsepower | 280 hp | 290 hp |
| Torque | 310 lb-ft | 255 lb-ft |
| Best For | Fuel Efficiency/Daily Driving | Simplicity/Towing |
Frequently Asked Questions About the ford explorer 2016
How do I know if my water pump is failing?
Look for a low coolant warning or a sweet smell coming from the engine bay. Check your oil dipstick; if the oil looks like chocolate milk, the internal seal has failed, and coolant is entering the crankcase. This is a critical failure that requires immediate attention.
Can I upgrade the SYNC system in my 2016 model?
Most 2016 models came with SYNC 2 (MyFord Touch). You can upgrade to SYNC 3 by swapping the recessed screen and APIM module from a later model year. This allows for much faster performance and the use of Apple CarPlay and Android Auto.
What is the maximum towing capacity?
When properly equipped with the Class III trailer tow package, the V6 models can tow up to 5,000 pounds. The 2.3L EcoBoost is generally rated for 3,000 pounds. Always use a weight-distributing hitch for larger loads to maintain steering stability.
Why does my car smell like exhaust inside the cabin?
This was a common complaint for this generation. It is often caused by unsealed body seams in the rear cargo area or issues with the exhaust tips. Ford issued several technical service bulletins (TSBs) to address this, involving sealing the rear vents and reprogramming the HVAC system.
