Understanding the 2017 ford explorer xlt awd
The XLT trim with All-Wheel Drive (AWD) is perhaps the most popular configuration for this model year. It typically features the 3.5L Ti-VCT V6 engine, though some may have the 2.3L EcoBoost. Understanding how these components interact is the first step in effective preventative maintenance.
The Intelligent 4WD and Terrain Management System
Unlike old-school 4×4 systems, the AWD in this Explorer is proactive. It monitors wheel speed, throttle position, and steering angle to distribute torque before slip even occurs. The center console dial allows you to select modes like Mud, Rut, Sand, or Grass/Gravel/Snow.
Each mode changes how the Powertrain Control Module (PCM) manages engine torque and braking pressure. For example, in Sand mode, the system stays in lower gears longer to maintain momentum. Understanding these settings can prevent unnecessary strain on the transmission when you are off-road.
The Power Transfer Unit (PTU) Explained
The PTU is a small gearbox that sends power from the front-mounted transaxle to the rear wheels. In the 2017 Ford Explorer, the PTU is a known “hot spot” because it sits very close to the exhaust manifold. This heat causes the gear oil to break down and turn into a thick, sludge-like consistency.
Ford often marketed the PTU fluid as “filled for life,” but experienced technicians disagree. To ensure your AWD system doesn’t seize, you should inspect this fluid regularly. If your PTU doesn’t have a drain plug, you may need to use a suction pump to extract the old oil through the fill hole.
Essential Maintenance for the 3.5L V6 Engine
The 3.5L Duratec (Cyclone) V6 is a workhorse, but it has one major design flaw that every owner must know. This engine uses an internal water pump driven by the timing chain. If the pump fails, it can leak coolant directly into the engine oil, leading to catastrophic engine failure.
Monitoring the Water Pump “Weep Hole”
Ford designed a weep hole behind the alternator that allows leaking coolant to exit the engine block before it mixes with the oil. As a DIYer, you should check this area every time you change your oil. Look for crusty orange or green residue, which indicates the pump’s internal seals are starting to fail.
If you see a leak, do not wait. Replacing the water pump is a labor-intensive job because the timing cover must be removed. However, it is significantly cheaper than replacing the entire engine. Always use a high-quality Motorcraft replacement pump to ensure longevity.
Oil Changes and Filter Selection
Stick to a 5,000-mile oil change interval rather than following the Intelligent Oil-Life Monitor to its limit. Use a full synthetic 5W-20 oil to keep the variable valve timing (VCT) solenoids clean. These solenoids have tiny screens that can clog with sludge, causing rough idles and check engine lights.
I recommend using the Motorcraft FL-820S filter. It features a silicone anti-drainback valve that prevents dry starts. For those living in dusty environments or doing light off-roading, changing your engine air filter every 15,000 miles is a cheap way to maintain fuel economy.
Transmission and Drivetrain Care
The 6F50 6-speed automatic transmission in the 2017 Ford Explorer is generally reliable, but it generates significant heat when towing or climbing. Keeping the fluid fresh is the best way to avoid shuddering or delayed shifts. This is especially true if you frequently use the AWD capabilities.
Transmission Fluid Service (Drain and Fill)
Instead of a high-pressure flush, which can dislodge debris, perform a simple “drain and fill.” You will typically get about 5 to 6 quarts of Mercon V fluid out of the pan. Doing this every 30,000 to 45,000 miles will keep the clutch packs healthy and the shifts crisp.
When checking the fluid level, ensure the engine is running and the transmission is at operating temperature. The dipstick on the 2017 model is located low in the engine bay, often requiring a long funnel to reach. Always use a lint-free rag to wipe the dipstick to avoid contaminating the system.
Rear Differential Service
The rear differential is often overlooked. It houses the clutch pack that engages the rear wheels. Use a high-quality 75W-85 or 75W-90 synthetic gear oil. If you submerge the rear axle during a boat launch or deep puddle crossing, check the fluid immediately for a milky appearance, which indicates water contamination.
Common Suspension and Chassis Issues
The Explorer is a heavy vehicle, and that weight takes a toll on the suspension components. If you notice a “clunking” sound over bumps or the car feels loose in corners, it is time to inspect the bushings and links. Safety is paramount here, as suspension failure can lead to loss of control.
The Rear Toe Link Recall
The 2017 Ford Explorer was part of a major recall regarding the rear suspension toe links. These links can fracture due to stress, causing a sudden change in steering handling. Check your VIN on the NHTSA website to ensure this recall has been performed on your vehicle.
Even if the recall was done, these parts can wear out. Look for excessive play in the rear wheels when the vehicle is on jack stands. Replacing these links is a straightforward DIY task, but you must get a four-wheel alignment immediately afterward to prevent rapid tire wear.
Front Struts and Lower Control Arms
Front-end “creaking” is often caused by worn lower control arm bushings. Because the bushings are pressed in, it is often easier for a DIYer to replace the entire control arm assembly. When installing new struts, consider a “quick-strut” assembly that includes the spring and mount to save time and avoid the dangers of a spring compressor.
Off-Road Setup and Performance Upgrades
While the XLT isn’t a dedicated rock crawler, it is surprisingly capable on forest service roads and beach sand. A few strategic upgrades can make your 2017 ford explorer xlt awd much more adventurous without ruining the daily drive quality.
Tire Selection for Traction
The best upgrade for any AWD vehicle is a set of All-Terrain (A/T) tires. Look for tires like the Falken Wildpeak A/T Trail or the Michelin LTX A/T2. These provide better puncture resistance and grip in the dirt while remaining quiet on the highway.
If you plan on driving in deep snow, ensure the tires have the Three-Peak Mountain Snowflake (3PMSF) symbol. This rating indicates the tire meets specific snow traction requirements. Proper tires allow the Intelligent 4WD system to work much more efficiently by providing the mechanical grip the computers expect.
Adding a Leveling Kit
A 1.5-inch to 2-inch front leveling kit can give the Explorer a more aggressive stance and improve the approach angle. This involves installing spacers on top of the front struts. It provides just enough clearance to avoid scraping the front air dam on moderate trails.
Keep in mind that lifting the vehicle changes the center of gravity. Always re-aim your headlights after a lift or level to avoid blinding oncoming traffic. Additionally, check your CV axle boots for stretching, as the increased angle can sometimes lead to premature boot failure.
Safety First: Braking and Electrical
A vehicle that goes must also stop. The Explorer’s braking system is robust, but the rotors are prone to warping if they get too hot during mountain descents. If you feel a vibration in the steering wheel when braking, your rotors are likely “out of true.”
Upgrading Brake Components
For those who tow trailers or carry heavy loads, consider upgrading to ceramic brake pads and slotted rotors. Ceramic pads produce less dust and handle heat better than standard semi-metallic pads. Always use a torque wrench on your lug nuts (100 lb-ft) to ensure even pressure on the rotor hat, which prevents warping.
Battery and Alternator Health
The 2017 Explorer is packed with electronics, from the SYNC 3 infotainment to the electric power steering. A weak battery can cause “ghost” electrical issues, such as random warning lights or sluggish screen response. Test your battery every fall, especially if you live in a cold climate.
If you add off-road lights or a winch, consider upgrading to an AGM (Absorbed Glass Mat) battery. These are more resistant to vibration and deep discharges. Ensure all ground wires are clean and tight, as a loose ground is the most common cause of electrical gremlins in modern Fords.
Frequently Asked Questions About the 2017 ford explorer xlt awd
How often should I change the PTU fluid?
While Ford doesn’t provide a specific interval for “normal” driving, most enthusiasts and mechanics recommend changing the PTU fluid every 30,000 miles. This is especially important if you live in a hot climate or use the AWD system frequently.
Can I tow a trailer with the XLT AWD?
Yes, when properly equipped with the Class III Trailer Tow Package, the 2017 Explorer XLT can tow up to 5,000 lbs. Without the factory package, the limit is significantly lower. Always use a weight-distribution hitch for larger loads to maintain steering stability.
