2017 Ford Explorer Life Expectancy – Pro Tips For A 200,000-Mile Suv
A well-maintained 2017 Ford Explorer typically lasts between 200,000 and 250,000 miles. To reach this milestone, owners must proactively manage specific issues like the internal water pump on the 3.5L engine and the Power Transfer Unit (PTU) fluid.
You want a vehicle that can handle the school run, the daily commute, and the occasional weekend trail ride without breaking a sweat. When you research the 2017 ford explorer life expectancy, you likely see a range of numbers that leave you wondering where your specific SUV fits in.
I promise that by the end of this guide, you will know exactly which mechanical “ticking time bombs” to defuse and how to structure your maintenance for maximum longevity. We will dive deep into the specific engine choices, drivetrain quirks, and the DIY checks that separate a 100,000-mile trade-in from a 250,000-mile legend.
We are going to look at everything from the EcoBoost turbo health to the often-ignored PTU fluid changes. Whether you are a weekend mechanic or a dedicated owner, these insights will help you keep your Explorer on the road for years to come.
What is the Realistic 2017 Ford Explorer Life Expectancy?
For most owners, the 2017 ford explorer life expectancy sits comfortably at the 200,000-mile mark. If you drive the average 15,000 miles per year, this translates to roughly 13 to 17 years of service.
However, hitting these high numbers is not an accident; it is the result of preventative maintenance. Some high-mileage heroes have even pushed these vehicles past 300,000 miles with original engines, though this usually involves highway-heavy driving.
The 2017 model year is generally considered more reliable than the earlier years of the fifth generation. Ford addressed several electronic gremlins and transmission software issues by this time, making it a solid platform for long-term ownership.
Factors That Influence the Lifespan
Your driving environment plays a massive role in how long your Ford Explorer lasts. Vehicles in the “Rust Belt” face chassis corrosion, while those in hot climates deal with thermal stress on plastic cooling components.
Towing also changes the math significantly. If you frequently haul a boat or a camper, you are putting extra strain on the transmission and rear suspension, which can shorten the lifespan of those specific components.
The “Silent Killer”: The 3.5L Ti-VCT Internal Water Pump
The most critical factor in the 2017 ford explorer life expectancy for models equipped with the 3.5L Cyclone V6 is the water pump. Unlike most cars, this water pump is located inside the engine and driven by the timing chain.
When this pump fails, it often leaks coolant directly into the oil pan. This creates a “milkshake” consistency that destroys engine bearings in a matter of minutes. If you don’t catch it immediately, the engine is usually a total loss.
To prevent this, you must inspect your oil frequently. Look for a milky appearance on the dipstick or a rising oil level. Many experts recommend replacing the water pump and timing chain as a preventative measure around 120,000 to 150,000 miles.
Warning Signs of Water Pump Failure
- A low coolant warning without any visible puddles on the ground.
- A slight sweet smell coming from the engine bay after a long drive.
- Cloudy or “frothy” oil on the dipstick during your monthly check.
If you see any of these signs, do not drive the vehicle. Tow it to a shop to have the cooling system pressure tested. Catching a weep early can save you the $5,000 to $7,000 cost of a replacement engine.
Drivetrain Durability: The PTU and Transmission
Maximizing the 2017 ford explorer life expectancy requires more than just engine care; you have to look at the Power Transfer Unit (PTU). This component sends power to the rear wheels in All-Wheel Drive (AWD) models.
Ford originally claimed the PTU fluid was “lifetime,” but many enthusiasts and mechanics disagree. The PTU holds a very small amount of gear oil (about 18 ounces) and sits very close to the exhaust manifold, causing the oil to cook and turn into sludge.
To reach 200,000 miles, you should change your PTU fluid every 30,000 miles. Since the 2017 model doesn’t always have a drain plug, you may need to use a fluid extractor to suck the old oil out through the fill hole.
Transmission Health Tips
The 6F55 and 6F50 6-speed transmissions in these vehicles are generally robust. However, they are sensitive to heat. If you use your Explorer for off-roading or heavy towing, consider installing an auxiliary transmission cooler.
Avoid “flushing” the transmission at high mileage if it hasn’t been done regularly. Instead, perform a simple “drain and fill” every 50,000 miles. This refreshes the detergent package in the fluid without dislodging debris that could clog internal valves.
EcoBoost Engine Specifics: Turbo and Carbon Care
If your 2017 Explorer has the 2.3L or 3.5L EcoBoost engine, you have a different set of priorities. These are gasoline direct injection (GDI) engines, which are prone to carbon buildup on the intake valves.
Since fuel doesn’t wash over the valves in a GDI engine, oil vapors can bake onto them. Over time, this causes rough idling and lost fuel economy. Using a high-quality full synthetic oil and an intake cleaning spray every 30,000 miles can mitigate this.
Turbocharger longevity is also key. Always let your engine idle for 30 to 60 seconds after a hard highway run. This allows oil to circulate and cool the turbo bearings, preventing the oil from “coking” inside the turbocharger lines.
The Importance of Spark Plugs
EcoBoost engines are very hard on spark plugs. A worn plug can cause a misfire, which puts immense stress on the ignition coils and can eventually damage the catalytic converters.
For the best results, change your spark plugs every 40,000 to 50,000 miles. Use the exact Motorcraft plugs recommended by the manual. This small investment keeps the combustion cycle clean and protects the engine’s long-term health.
Off-Road and Heavy-Duty Use Considerations
Driving habits play a massive role in the 2017 ford explorer life expectancy for those who tow frequently. While the Explorer is a capable “soft-roader,” it is a unibody vehicle, not a body-on-frame truck.
Repeatedly bottoming out the suspension on rocky trails will wear out your struts and control arm bushings prematurely. If you hear a “clunk” when going over speed bumps, your sway bar links or bushings likely need replacement.
After any off-road excursion, always wash the undercarriage. Mud and salt trap moisture against the steel components, leading to structural rust. Pay special attention to the rear suspension mounting points and the brake lines.
Braking and Suspension Upgrades
If you plan on keeping your Explorer for the long haul, consider upgrading to heavy-duty brake pads and rotors. The Explorer is a heavy vehicle, and the stock brakes can warp if they get too hot during mountain descents.
Check your CV boots regularly. A torn boot allows dirt into the constant velocity joint, which will cause it to fail. Replacing a $20 boot is much cheaper than replacing a $200 axle assembly later on.
Proactive Maintenance Schedule for 200k Miles
To beat the average 2017 ford explorer life expectancy, you cannot follow the “normal” service intervals in the manual. Those are often designed for the “first owner” experience, not the “forever car” experience.
- Engine Oil: Change every 5,000 miles using full synthetic. Do not wait for the “Oil Life Monitor” to hit 0%.
- Coolant Flush: Every 60,000 miles. Fresh coolant protects the internal water pump seals from abrasive debris.
- PTU Fluid: Every 30,000 miles. This is the single best thing you can do for AWD longevity.
- Transmission Fluid: Drain and fill every 50,000 miles.
- Brake Fluid: Flush every 2 years to prevent moisture from corroding the ABS module.
Keep a detailed log of every service. Not only does this help you stay organized, but it also significantly increases the resale value if you ever decide to part with the vehicle. A buyer will pay a premium for a car with a stack of receipts.
When to Fix It vs. When to Trade It In
Every vehicle eventually reaches a point of diminishing returns. However, with the current price of new SUVs, spending $3,000 on a major repair often makes more financial sense than taking on a $600 monthly car payment.
If your Explorer has a solid frame and the interior is in good shape, a transmission rebuild or a water pump replacement is usually worth the investment. These repairs effectively “reset” the clock on those major systems.
However, if you start seeing significant rust on the frame or the electrical system begins to fail in multiple areas (ghost in the machine), it might be time to move on. Structural integrity and safety should always be your top priorities.
