2016 Ford Explorer Police Car – The Ultimate Buyer And Maintenance
The 2016 Ford Explorer Police Interceptor Utility is a heavy-duty version of the standard SUV, featuring reinforced components designed for high-speed pursuits and long idling hours. This guide explores how to maintain, troubleshoot, and optimize these retired fleet vehicles for civilian use, off-roading, or DIY projects. Whether you are looking at a 3.7L Ti-VCT or a 3.5L EcoBoost model, understanding the unique police-spec upgrades is key to long-term reliability.
Buying a retired fleet vehicle can feel like a gamble, especially when that vehicle spent its first life chasing suspects and idling in parking lots. You might be wondering if the rugged upgrades are worth the potential for high-wear engine components and a stripped-out interior.
The good news is that a 2016 ford explorer police car, officially known as the Police Interceptor Utility (PIU), is built on a significantly stronger foundation than the base Explorer. From heavy-duty suspension to upgraded cooling systems, these machines are designed to take a beating that would sideline a standard family hauler.
In this guide, we will dive deep into the mechanical specifics that set these vehicles apart. We will also cover the critical maintenance steps you need to take to ensure your retired cruiser remains a dependable daily driver or a capable off-road rig.
What Makes the 2016 Ford Explorer Police Car Different from Civilian Models?
At first glance, the PIU looks like a standard Explorer with a beefy push bar and steel wheels. However, the differences under the skin are substantial, starting with the heavy-duty cooling system. These vehicles use larger radiators and high-output fans to manage heat during prolonged idling and high-speed driving.
The braking system is another major upgrade. The PIU features larger brake rotors and specialized calipers designed for repeated high-energy stops without fading. This makes them excellent candidates for towing or heavy-duty hauling where standard brakes might struggle.
Structurally, the 2016 ford explorer police car includes reinforced subframes and heavy-duty suspension components. The springs, struts, and sway bars are tuned for better handling and weight distribution, which helps the vehicle stay planted during aggressive maneuvers. This stiffness is a benefit for those who want a more “connected” feel on the road.
Reinforced Wheels and Tires
Unlike the alloy wheels found on civilian trims, the Interceptor Utility comes standard with heavy-duty steel wheels. These 18-inch wheels are designed to withstand curb strikes and rough terrain without cracking or shattering like aluminum might.
The tires are typically pursuit-rated, meaning they have stiffer sidewalls for better cornering. If you are converting your PIU for off-road use, these steelies provide a perfect platform for aggressive all-terrain tires without worrying about cosmetic damage to expensive rims.
Interior and Electrical Differences
Inside, you will notice the absence of a center console, as this space was originally reserved for police radios and equipment. The shifter is moved to the steering column to clear floor space. This layout is a dream for DIYers who want to install custom storage or specialized electronics.
The electrical system is also significantly beefier. A high-output alternator (usually 220 amps) is standard to power light bars, computers, and sirens. This extra juice is incredibly useful if you plan on adding winches, off-road lighting, or high-end audio systems later on.
Powertrain Options: Choosing the 3.7L Ti-VCT vs. the 3.5L EcoBoost
When shopping for a 2016 ford explorer police car, you will primarily find two engine options. The most common is the 3.7L Ti-VCT V6, which is a naturally aspirated workhorse known for its longevity. It produces a respectable 304 horsepower and is generally easier to maintain for the average DIYer.
For those seeking more performance, the 3.5L EcoBoost twin-turbo V6 is the powerhouse of the lineup. Delivering 365 horsepower and 350 lb-ft of torque, this engine turns the Explorer into a surprisingly fast machine. However, turbochargers introduce more complexity and potential leak points in the vacuum and cooling lines.
Both engines are paired with a 6-speed SelectShift automatic transmission that is calibrated for “Pursuit Mode.” This software profile allows for more aggressive downshifts and holds gears longer during spirited driving. Both models also feature a heavy-duty All-Wheel Drive (AWD) system as standard equipment.
The Importance of Idle Hours
When evaluating these engines, ignore the odometer for a moment. You must check the engine idle hours. One hour of idling is roughly equivalent to 33 miles of driving. A car with 100,000 miles but 5,000 idle hours has significantly more wear than one with the same mileage and low idle time.
High idle hours can lead to carbon buildup on the valves and premature wear on the internal water pump. This is a critical point for the 3.5L and 3.7L Cyclone engines, as the water pump is driven by the timing chain. If it fails, it can leak coolant directly into the oil pan, potentially destroying the engine.
Critical Maintenance for the Power Transfer Unit (PTU)
The AWD system in the 2016 ford explorer police car relies on a Power Transfer Unit (PTU) to send torque to the rear wheels. In the civilian world, Ford often claimed these units were “lubed for life.” In the police world, we know better. The PTU sits very close to the exhaust, causing the gear oil to cook and turn into a thick, sludge-like consistency.
To prevent PTU failure, you should change the 75W-140 gear oil every 20,000 to 30,000 miles. Many Interceptors do not have a drain plug, requiring you to vacuum the old fluid out through the fill hole. It is a messy job, but it is much cheaper than replacing the entire unit.
If you notice a “propane” or “burnt” smell after driving, or if you see a milky residue near the PTU vent, your fluid is likely compromised. Addressing this early is the difference between a reliable rig and a costly repair bill that requires dropping the subframe.
Servicing the Rear Differential
While the PTU gets all the attention, don’t forget the Rear Drive Unit (RDU). The rear differential also works hard in pursuit-rated vehicles. Changing the fluid here is much easier than the PTU and should be done on the same schedule to ensure the AWD system operates smoothly.
Use a high-quality synthetic gear lubricant and check for metal shavings on the magnetic drain plug. A small amount of “fuzz” is normal, but large chunks indicate internal wear that may lead to humming or vibrations at highway speeds.
Common Electrical Issues and “Dark Mode”
One of the most frequent questions regarding a 2016 ford explorer police car involves the “Dark Mode” or “Police Silent Mode.” This feature disables all interior lighting when the doors are opened, which is great for stealth but annoying for grocery runs at night. Fortunately, this can be toggled using FORScan software and a compatible OBDII adapter.
You may also encounter “ghost” wiring. When police equipment is removed, technicians often snip wires rather than unplugging them. This can leave live wires tucked under the dash or in the headliner. Always use a multimeter to check for voltage before tapping into any existing harness.
The 2016 model year also features the Sync system, though it is often the basic 4-inch screen version. Upgrading to a larger touchscreen or adding Apple CarPlay/Android Auto is a popular mod, but you may need to source a civilian dash bezel and wiring adapters to make everything look factory-correct.
Handling Roof and Body Holes
Most retired cruisers will have holes in the roof or trunk from antennas and light bars. If these aren’t sealed correctly, water will leak into the cabin, leading to mold and electrical corrosion. Don’t just slap duct tape over them.
The professional way to fix this is with threaded hole plugs and silicone sealant. For a more permanent solution, some owners choose to weld the holes shut and repaint the roof. At a minimum, ensure every hole is watertight before the first rainstorm hits your new purchase.
Suspension and Braking: Restoring Ride Quality
Because the 2016 ford explorer police car is tuned for performance, the ride can be quite stiff. If the vehicle has high mileage, the struts and shocks are likely tired. Replacing them with OEM Interceptor parts will maintain that sharp handling, while switching to civilian-spec struts will soften the ride for family use.
Pay close attention to the rear toe links. This is a known weak point on the Explorer platform, and Ford has issued several recalls for them. A snapped toe link can cause a loss of steering control in the rear, so ensure the recall work has been performed by a dealership.
When it comes to brakes, always stick with heavy-duty pads and rotors. The PIU uses a different part number than the base Explorer. Using civilian pads on an Interceptor can lead to poor fitment and reduced stopping power, especially if you are still using the original heavy-duty calipers.
Inspecting Bushings and Ball Joints
The aggressive driving these cars endure takes a toll on rubber components. Inspect the lower control arm bushings and ball joints for cracks or play. If you hear a clunking sound when going over bumps or turning the wheel, it is a sign that the front end needs some attention.
Replacing the entire control arm is often easier for the DIYer than trying to press out old bushings. This also gives you a fresh ball joint, ensuring your alignment stays true and your tires wear evenly over time.
DIY Inspection Checklist: What to Look for Before Buying
If you are standing in front of a 2016 ford explorer police car at an auction or a private sale, use this checklist to separate the gems from the junk:
- Check the Coolant: Look for a “milkshake” appearance in the oil or oil in the coolant. This indicates a failing internal water pump.
- Verify Idle Hours: Cycle through the dashboard menu to find “Engine Hours” and “Idle Hours.” Aim for the lowest ratio possible.
- Test the AWD: Find a patch of gravel and accelerate moderately. Ensure the rear wheels engage without clunking or “binding” sensations.
- Smell the PTU: If the area around the front passenger side smells like burnt gear oil, the PTU is overheating or leaking.
- Inspect the Roof: Check for poorly sealed holes that could lead to headliner damage and electrical shorts.
- Check Transmission Shifts: The “Pursuit” tune is firm, but it shouldn’t “slam” into gear or slip between shifts.
Don’t be afraid to walk away if the engine sounds like a “sewing machine” (indicating timing chain stretch) or if the idle hours are excessively high (above 8,000). There are plenty of these vehicles hitting the secondary market, so you can afford to be picky.
Frequently Asked Questions About the 2016 Ford Explorer Police Car
Is the 2016 Ford Explorer Police Car bulletproof?
While some Interceptors were fitted with ballistic door panels as an option, most are not “bulletproof.” You can check for the presence of these panels by looking for a heavy-duty sticker on the inside of the door jam or by the significant extra weight of the door itself.
Can I install a regular center console in a police Explorer?
Yes! Many owners source center consoles from wrecked civilian Explorers at junkyards. Since the shifter is on the column in the PIU, you actually get extra storage space where the civilian shifter would normally be. Some minor trimming of the floor carpet may be required.
What is the fuel economy like on a retired police car?
Expect around 16-18 MPG in the city and 21-23 MPG on the highway. The 3.5L EcoBoost will be on the lower end of that spectrum if you have a heavy foot. The AWD system and heavy-duty components add weight, which makes them slightly less efficient than a front-wheel-drive civilian model.
Why is my speedometer so accurate?
The 2016 ford explorer police car features a “certified calibration” speedometer, usually marked in 2-mph increments. It is designed to be extremely accurate for pacing other vehicles. This is a nice perk for drivers who want precise speed data without relying on GPS.
Conclusion: Is the Interceptor Utility Right for You?
Owning a 2016 ford explorer police car is a unique experience that offers a blend of utility, performance, and ruggedness. While they require more diligent maintenance—specifically regarding the PTU and cooling system—the rewards are a vehicle that can handle far more than your average crossover.
If you are a DIY mechanic, these cars are a fantastic canvas. They are designed to be serviced quickly, and the abundance of spare parts makes repairs relatively affordable. By staying ahead of the “big” issues like the internal water pump and gear oil degradation, you can enjoy a heavy-duty SUV for years to come.
Take your time during the inspection, prioritize fluid changes immediately after purchase, and don’t be afraid to customize the interior to fit your needs. Whether you’re building a budget overlander or a tough daily driver, the Interceptor Utility is a powerhouse waiting for its second act. Stay safe and enjoy the drive!
