Let’s dive into the specifics of these high-performance machines and see what makes them tick. We will prioritize safety and practical mechanical advice every step of the way.
Understanding the Mechanical DNA of a Ford Police SUV
The ford police suv, officially known as the Police Interceptor Utility (PIU), is not just an Explorer with a push bar. Ford engineers redesigned several key systems to withstand the rigors of 24/7 duty cycles. This includes a reinforced subframe and heavy-duty suspension components designed for curb jumping.
One of the most significant upgrades is the cooling system. These vehicles feature a larger radiator, a high-volume oil cooler, and a specialized transmission cooler. These parts allow the engine to idle for hours in high heat without overheating, a common killer of civilian SUVs.
The braking system is also beefed up significantly. You will find larger rotors and specialized calipers that use heavy-duty brake pads. These are designed to resist brake fade during high-speed pursuits, making them excellent for towing or descending steep mountain grades while off-roading.
Suspension and Chassis Reinforcements
The springs and struts on a PIU are much stiffer than those on a civilian Explorer. This reduces body roll and increases the payload capacity. Ford also adds heavy-duty hubs and bearings to handle the increased unsprung weight of the steel wheels.
Underneath, you will often find additional skid plates and shielding. These protect the fuel tank and engine oil pan from debris. For an off-roader, this provides a fantastic baseline for a trail-ready build without needing expensive aftermarket armor immediately.
The Pursuit-Rated Drivetrain
Most 2013-2019 models come with either the 3.7L Ti-VCT V6 or the 3.5L EcoBoost twin-turbo V6. Unlike the civilian models, these do not have a speed limiter set at 110 mph. They are designed to stay stable at much higher speeds, which requires a balanced driveshaft and high-speed rated tires.
The All-Wheel Drive (AWD) system is also tuned differently. It provides a more aggressive torque split to the rear wheels. This helps the vehicle rotate through corners and provides better traction on loose surfaces like gravel or snow.
Evaluating Engine Hours vs. Total Mileage
When shopping for a ford police suv, the odometer is only half the story. Police vehicles spend a massive amount of time idling to keep electronics running and climate control active. This is why Ford included an idle hour meter in the instrument cluster.
To check this, toggle through the steering wheel menu to find “Engine Hours” and “Idle Hours.” Industry experts generally agree that one hour of idling is equivalent to approximately 33 miles of driving wear. A car with 100,000 miles but 5,000 idle hours has significantly more wear than one with 1,000 idle hours.
High idle hours specifically affect the valvetrain and the water pump. On the 3.5L and 3.7L Cyclone engines, the water pump is internal and driven by the timing chain. If it fails, it can leak coolant directly into the oil, leading to catastrophic engine failure. Always check the oil dipstick for a milky appearance during inspection.
Decoding the Service Records
Most departments follow strict maintenance schedules. Try to obtain the service logs from the municipality selling the vehicle. Look for frequent oil changes (every 3,000 to 5,000 miles) and records of transmission or PTU fluid swaps.
If the records show a recent transmission replacement, that is a huge win for a buyer. These transmissions take a beating during “J-turns” and rapid acceleration. A fresh unit saves you thousands of dollars in future repair costs.
Checking for “Hole” Issues
Police vehicles are covered in antennas, light bars, and spotlights. When these are removed, they leave holes in the roof, pillars, and trunk. Check how these were plugged. If they used simple rubber bungs, you might have moisture intrusion in the headliner or electrical shorts.
Inspect the A-pillar where the spotlight was mounted. Sometimes the hole is left open, allowing rain to drain into the dashboard. Use a high-quality silicone sealant or permanent metal plugs to seal these up as your first DIY project.
Maintenance Pitfalls for a Used Ford Police SUV
Maintaining a ford police suv requires a different mindset than a standard car. You are dealing with a vehicle that has likely been driven to its absolute limit. The first thing any new owner should do is a “baseline” service, which means changing every fluid in the vehicle.
The most critical component to service is the Power Transfer Unit (PTU). This is the small gearbox that sends power to the rear wheels. In the PIU, the PTU sits very close to the exhaust manifold, which causes the gear oil to cook and turn into a sludge-like consistency. If you don’t change this fluid, the PTU will eventually seize.
I recommend using a vacuum pump to suck out the old 75W-140 gear oil and replacing it with high-quality synthetic fluid. Do this every 20,000 miles to ensure the longevity of your AWD system. It is a messy job, but it is much cheaper than replacing the entire unit.
The Internal Water Pump Challenge
As mentioned earlier, the internal water pump is the “Achilles heel” of the Ford V6 engines. If you hear a faint grinding or see coolant weeping from a small hole behind the alternator (the weep hole), stop driving immediately. This is a sign the pump is about to fail.
Replacing the water pump is a labor-intensive job because it requires removing the timing chain. If you are doing this yourself, always replace the timing chain, tensioners, and guides at the same time. It is a “once-in-a-decade” repair that preserves the engine for another 150,000 miles.
Heavy-Duty Brake Service
When it comes time for a brake job, do not buy standard Explorer pads. Ensure you specify the “Police Package” or “Heavy Duty” options. These pads have a different friction material designed for higher heat ranges.
Always clean and grease the slide pins on the calipers. Because these vehicles often sit in salty or dusty environments, the pins tend to seize. This leads to uneven pad wear and reduced stopping power. Use a high-temp ceramic brake grease for the best results.
The “Civilianizing” Process: Interior and Electrical
Most retired units come with a “stripped” interior. You will likely find a vinyl rear seat (designed for easy cleaning), no center console, and a heavy-duty rubber floor mat instead of carpet. While utilitarian, this can be loud and uncomfortable for daily use.
One of the most popular mods is a “console swap.” You can source a center console from a wrecked civilian Explorer and bolt it directly into the PIU. You may need to fabricate small brackets, but it provides much-needed armrests and cupholders. This instantly makes the cabin feel more premium.
Be careful with the electrical system. Departments often “decommission” vehicles by simply cutting the wires for the sirens and lights. This leaves a spaghetti mess of live wires under the dash. Spend a weekend with a multimeter and some heat-shrink tubing to cap off or remove these redundant circuits.
Managing “Dark Mode” and Stealth Features
Police Fords often have “Dark Mode” enabled. This prevents the interior lights from turning on when you open the doors—a feature used for tactical approaches. If you want your dome lights back, you will need a tool called FORScan and an OBDII adapter.
FORScan allows you to access the vehicle’s computer (BCM) and toggle these features back to civilian settings. You can also use it to disable the “Chirp” when locking or to add an aftermarket remote start system. It is an essential tool for any Ford DIYer.
Upgrading the Seats
The front seats in a police SUV are designed with “bolt-out” sections to accommodate an officer’s utility belt. This can make them feel a bit wide or unsupportive for average drivers. If the foam is crushed, consider swapping in seats from a Limited or XLT trim Explorer for better lumbar support.
Keep in mind that police seats often have ballistic panels in the backrests. These are heavy steel plates designed to protect the officer from shots fired from behind. While they offer extra safety, they add significant weight to the vehicle.
Building a Ford Police SUV for Off-Road Use
The ford police suv is a fantastic platform for a budget overlander. Because it already has a heavy-duty cooling system and a reinforced chassis, it can handle trails that would make a standard crossover struggle. However, there are a few modifications you should consider to maximize its potential.
First, address the ground clearance. A 1.5-inch or 2-inch leveling kit is usually enough to fit larger All-Terrain tires. Look for tires with a stiff sidewall to complement the PIU’s heavy-duty suspension. This setup will allow you to navigate fire roads and moderate trails with ease.
Since the PIU lacks a traditional low-range transfer case, you rely on the traction control system. Ensure your ABS sensors are clean and functional. The computer uses these sensors to brake spinning wheels and send torque to the tires with grip.
Adding Recovery Points
Most police units come with a front push bar (like a Setina or GoRhino). While these look cool, they are often mounted to the bumper supports and are not suitable for heavy recovery. If you get stuck, do not pull from the push bar.
Install a Class III or IV hitch receiver in the rear for a solid recovery point. For the front, look for specialized tow hooks that bolt directly to the frame rails. Always use rated shackles and kinetic recovery ropes rather than chains for safety.
Lighting and Power for Camping
Since the vehicle already has heavy-duty wiring pass-throughs in the firewall, adding auxiliary lights is easy. You can repurpose the existing spotlight mounts for high-powered LED pods. These are perfect for illuminating a campsite or spotting obstacles on a night run.
The high-output alternator (usually 220 amps or more) is a massive advantage. It can easily charge a secondary “house” battery system to power a portable fridge or an inverter for your tools. This makes the PIU a superior choice for long-distance travel compared to vehicles with smaller alternators.
Frequently Asked Questions About Ford Police SUV
Is a Ford Police SUV reliable for a daily driver?
Yes, provided you account for the engine idle hours. If the cooling system and PTU are properly maintained, these vehicles can easily cross the 200,000-mile mark. They are built for durability, but they do require more frequent fluid changes than a standard car.
What is the difference between an Explorer and a Police Interceptor Utility?
The PIU has a reinforced frame, heavy-duty suspension, larger brakes, and an upgraded cooling system. It also lacks a roof rack and center console in the standard configuration. Most importantly, it is “pursuit-rated” for high-speed stability and rear-impact safety up to 75 mph.
How do I check the engine idle hours?
On the 2013-2019 models, use the directional pad on the left side of the steering wheel. Navigate to the “Information” or “Settings” menu in the gauge cluster. There you will find “Engine Hours” and “Idle Hours” displayed as numerical values.
Why do people buy these instead of civilian Explorers?
The primary reasons are cost and capability. You can often buy a ford police suv for half the price of a civilian model. Additionally, the mechanical upgrades make it a much better platform for towing, hauling, or off-roading.
Final Thoughts on the Interceptor Platform
Owning a ford police suv is a rewarding experience for those who appreciate heavy-duty engineering and a bit of “DIY” spirit. These vehicles offer a level of toughness that is hard to find in the modern crossover market. By focusing on the PTU maintenance and checking those engine hours, you can secure a high-performance machine for a bargain.
Remember to always prioritize safety when modifying your vehicle. Seal those roof holes, clean up the legacy wiring, and ensure your cooling system is in top shape before hitting the trails. These cruisers were built to serve, and with the right care, they will continue to serve you for years to come.
Stay safe, keep your wrenches ready, and enjoy the rugged capability of your Interceptor!
