We will dive deep into the three available engine platforms, explore the infamous “Giubo” flex disc issue, and look at how to prevent water from damaging your electrical components. Whether you are a seasoned DIY mechanic or a first-time owner, these insights will save you time and money at the repair shop. Let’s get under the hood and see what makes this van tick.
Understanding Your 2016 ford transit Engine Options
The 2016 ford transit was offered with three distinct engines, each requiring a different maintenance mindset. The 3.7L Ti-VCT V6 is the base naturally aspirated engine, known for its simplicity and long-term durability in fleet applications. It lacks the complexity of turbochargers, making it a favorite for those who prioritize low maintenance costs over raw towing power.
For those needing more “get-up-and-go,” the 3.5L EcoBoost V6 provides significant torque and horsepower, which is ideal for heavy builds or mountain driving. While powerful, this engine requires strict adherence to oil change intervals to protect the twin turbochargers from heat-related wear. Always use high-quality synthetic oil to prevent carbon buildup on the intake valves, a common trait of direct-injection engines.
The third option is the 3.2L Power Stroke I-5 Diesel, a specialized engine designed for high-mileage efficiency and heavy hauling. If you own the diesel variant, your primary focus should be on the Diesel Exhaust Fluid (DEF) system and the fuel filters. Neglecting the fuel-water separator on these units can lead to expensive high-pressure fuel pump failures that are difficult to repair at home.
Oil Change Intervals and Specifications
Regardless of your engine type, never follow the “extended” oil life monitors blindly if you operate in extreme conditions. For the 3.7L and 3.5L engines, a 5,000 to 7,500-mile interval is safer than the 10,000-mile limit often suggested by manufacturers. Use 5W-20 for the 3.7L and 5W-30 for the EcoBoost to ensure proper lubrication of the variable valve timing components.
The diesel 3.2L requires a specific low-ash oil to protect the Diesel Particulate Filter (DPF). Using the wrong oil can clog the emissions system, leading to a “limp mode” scenario that requires a forced regeneration at the dealership. Always double-check the Ford specification listed in your owner’s manual before pouring.
Common Mechanical Issues and DIY Fixes
Every vehicle has its “Achilles heel,” and the 2016 ford transit is no exception. One of the most documented issues involves the driveshaft flex disc, also known as the Giubo. This rubber coupling connects the transmission to the driveshaft and is designed to reduce vibrations, but it is prone to cracking and catastrophic failure over time.
Inspect your flex disc every time you perform an oil change. Look for small cracks or “threads” pulling away from the rubber; if you see these signs, replace the unit immediately. Ford issued several recalls for this part, so check your VIN with a local dealer to see if you are eligible for a free replacement of the updated u-joint style driveshaft.
Another unique problem for this model year is the “water shed” issue. The design of the cowl under the windshield allows rainwater to leak directly onto the engine cover and, in some cases, into the air filter box or onto the fuel injectors. This can cause engine misfires or even hydrolock if enough water enters the intake during a heavy downpour.
Solving the Water Ingress Problem
To fix the water leak, many DIYers use high-quality silicone sealant along the cowl seams where the two plastic pieces meet. You can also install a modified “gutter” or diverter to ensure water flows toward the drain holes rather than onto the engine. Periodically clear leaves and debris from the cowl drains to prevent backup.
Check your air filter regularly for signs of moisture or mold. If the filter paper looks wavy or damp, water is getting into the intake tract. Replacing the factory air box seal with a thicker weatherstripping can provide an extra layer of protection against the elements, especially if you live in a rainy climate.
Routine Maintenance for Long-Distance Reliability
The 6R80 six-speed automatic transmission in the 2016 ford transit is generally robust, but it is not “maintenance-free” as some marketing materials suggest. For a van that is frequently loaded to its Gross Vehicle Weight Rating (GVWR), the transmission fluid undergoes significant heat stress. I recommend a fluid and filter change every 60,000 miles to keep shifts crisp.
The 6R80 does not have a traditional dipstick under the hood; instead, it has a small “stubby” dipstick located on the side of the transmission case. Checking the level requires getting under the vehicle while the engine is running and the fluid is at operating temperature. Be extremely careful of the hot exhaust pipes located nearby during this process.
Your cooling system is another area that requires attention, especially the coolant expansion tank. These plastic tanks can develop hairline cracks over time, leading to slow leaks that are hard to spot. If you smell a sweet aroma after a long drive, inspect the tank and the quick-connect hose fittings for crusty orange residue.
- Serpentine Belt: Inspect for glazing or fraying every 50,000 miles.
- Spark Plugs: Replace every 60,000 miles on EcoBoost models to prevent misfires under boost.
- Brake Fluid: Flush the system every two years to remove moisture and prevent internal corrosion.
- Battery: The battery is located under the driver’s seat, making it a bit of a chore to replace—test it annually.
Suspension and Braking Care for Heavy Loads
The 2016 ford transit uses a MacPherson strut front suspension and a leaf-spring rear setup. Because these vans often carry heavy equipment or camper conversions, the factory shocks can wear out prematurely. If you notice the van “pogo-sticking” after a bump or leaning excessively in corners, it is time for an upgrade.
For those using their van for off-grid travel, consider installing heavy-duty shocks like Bilstein B6 or Fox Racing units. These provide better damping control and can handle the constant weight of a build-out. Additionally, adding “SumoSprings” or air helper springs can prevent rear-end sag and improve stability during high-wind highway driving.
Brake wear is highly dependent on how you drive and how much weight you carry. The Transit uses large disc brakes at all four corners, but the rear pads often wear faster than expected due to the Electronic Stability Control system’s frequent micro-adjustments. Always use high-quality ceramic pads to reduce dust and improve heat dissipation.
Brake Inspection Steps
- Loosen the lug nuts while the van is on the ground.
- Lift the vehicle using a heavy-duty floor jack and secure it with jack stands.
- Remove the wheel and inspect the brake rotor for grooves or “heat spots.”
- Check the thickness of the inner and outer pads; they should be replaced if they are below 3mm.
- Ensure the slider pins move freely; if they are stuck, the brakes will wear unevenly and lose efficiency.
Upgrading Your Transit for Off-Road or Van Life
If you plan on taking your 2016 ford transit off the beaten path, a few strategic upgrades will make a world of difference. While the Transit is primarily a rear-wheel-drive platform (unless you have an aftermarket 4×4 conversion), a good set of All-Terrain tires can significantly improve traction on gravel and dirt roads.
Size up slightly to a 245/75R16 for a bit more ground clearance, but be aware that this may require minor trimming of the plastic wheel well liners. A limited-slip differential (LSD) is another excellent upgrade for RWD owners. If your van came with an “open” differential, swapping in a Ford OEM LSD or an Eaton Truetrac will help prevent getting stuck in wet grass or light mud.
For interior comfort during camping, electrical upgrades are a must. Most owners install a “house” battery system charged via a DC-to-DC charger connected to the Transit’s high-output alternator. This allows you to run lights, fridges, and fans without draining the starter battery. Always use a fuse or circuit breaker close to the power source to prevent electrical fires.
Lighting and Visibility
The factory halogen headlights on the 2016 model are often described as “adequate” at best. For night driving in rural areas, consider upgrading to high-output LED bulbs or adding an auxiliary light bar behind the grille. This improves your reaction time by illuminating deer or obstacles well before you reach them.
Rear visibility is also a concern in cargo vans. If your van didn’t come with a backup camera, installing a rear-view camera system that integrates with a new head unit or a mirror-mounted monitor is a safety essential. It makes parking in tight city spots or maneuvering through campsites much less stressful.
Frequently Asked Questions About the 2016 Ford Transit
How do I know if my Giubo (flex disc) needs replacement?
Symptoms of a failing flex disc include a noticeable vibration through the floorboard, especially during acceleration, or a “clunking” sound when shifting from Park to Drive. Visually, you will see cracks in the rubber or frayed nylon cords. If you see any damage, do not delay replacement, as a failure can cause the driveshaft to detach and damage the transmission or fuel tank.
What is the best engine for a camper conversion?
The 3.5L EcoBoost is generally considered the best for heavy camper builds because its high torque output helps the van maintain highway speeds on steep grades. However, the 3.7L V6 is an excellent “budget” choice for lighter builds, offering lower maintenance complexity and high reliability. The 3.2L Diesel is great for those planning to drive 20,000+ miles per year, where fuel savings eventually offset the higher maintenance costs.
Why is my 2016 Ford Transit battery dying so quickly?
These vans have a complex electrical system that can have a “parasitic draw” if aftermarket accessories are installed incorrectly. Also, because the battery is tucked away under the seat, it often gets neglected. Ensure the terminals are tight and free of corrosion. If you frequently leave the doors open while working or camping, the interior lights and modules may stay awake, draining the battery; consider a “battery tender” if the van sits for long periods.
Can I lift my 2016 Ford Transit for more clearance?
Yes, there are several lift kits available, typically ranging from 2 to 3 inches. Companies like Van Compass and WeldTec Designs offer kits that include spacers or modified struts. A lift kit allows for larger tires and better approach angles, but keep in mind it will slightly change the van’s center of gravity and may affect fuel economy.
Final Thoughts on Maintaining Your Transit
The 2016 ford transit is a remarkably capable vehicle that can easily exceed 250,000 miles with the right care. By staying on top of the unique issues like the driveshaft flex disc and the cowl water leaks, you prevent small problems from turning into expensive roadside breakdowns. Remember that a van is more than just a car; it is a tool, a home, or a business, and it deserves a higher level of mechanical attention.
Always prioritize safety by checking your tires and brakes before any long trip. Use the right tools, follow torque specifications, and don’t be afraid to consult a professional for complex tasks like diesel timing or transmission internal work. With a consistent maintenance schedule, your Transit will continue to serve you faithfully for many years to come. Stay safe on the road and enjoy the drive!
