2017 Ford Transit 350 Passenger Van – Essential Maintenance
The 2017 Ford Transit 350 remains a powerhouse for large families and commercial fleets, offering unmatched seating versatility and robust engine options. To keep this vehicle running efficiently, owners must prioritize drivetrain inspections, water drainage management, and specific suspension care tailored to its high-capacity design.
Owning a 2017 ford transit 350 passenger van means you have one of the most capable haulers on the road. Whether you are using it for a cross-country family road trip or a professional shuttle service, its utility is undeniable.
However, maintaining a vehicle of this size requires a different mindset than a standard sedan. I will guide you through the technical nuances of this model, helping you identify potential issues before they leave you stranded on the shoulder.
In this guide, we will explore the best engine choices, tackle the common “Giubo” coupling problem, and provide a DIY maintenance schedule. My goal is to ensure your van stays reliable for many miles to come.
Key Performance Specs of the 2017 ford transit 350 passenger van
The 2017 ford transit 350 passenger van was designed to replace the aging E-Series, bringing better fuel economy and handling to the full-size segment. It features a unibody construction, which makes it much more agile than the body-on-frame vans of the past.
The “350” designation indicates a one-ton rating, which is essential for carrying up to 15 passengers safely. This model typically comes with a Gross Vehicle Weight Rating (GVWR) of 9,000 to 9,500 pounds, depending on the specific configuration and wheelbase.
Under the hood, you will most likely find the 3.7L Ti-VCT V6 or the more powerful 3.5L EcoBoost V6. Both engines are mated to a 6-speed SelectShift automatic transmission, known for its smooth shifting under heavy loads.
Choosing Between the 3.7L V6 and 3.5L EcoBoost
The 3.7L V6 is the “workhorse” engine, favored by fleet owners for its simplicity and long-term durability. It produces 275 horsepower and is relatively easy to service because it lacks the complexity of turbochargers.
If you frequently drive in mountainous terrain or tow a trailer, the 3.5L EcoBoost is the better choice. It delivers 400 lb-ft of torque, providing the low-end grunt needed to move a fully loaded passenger van up steep grades without breaking a sweat.
DIY mechanics should note that the EcoBoost requires more frequent oil changes. Turbocharged engines are sensitive to oil breakdown, so I recommend a high-quality synthetic oil every 5,000 miles to protect the twin turbochargers.
Common Mechanical Issues and DIY Solutions
Every vehicle has its quirks, and the 2017 ford transit 350 passenger van is no exception. Being aware of these common failure points can save you thousands of dollars in shop labor costs.
One of the most documented issues is the “airbox water leak.” The design of the windshield cowl can allow rainwater to drip directly onto the engine’s air intake box and even the fuel injectors.
Over time, this moisture leads to corrosion on the spark plugs or ignition coils, causing a rough idle or misfire. Many owners fix this by applying automotive-grade silicone sealant to the cowl seams or installing a diverted rubber flap to redirect water.
The Flexible Driveshaft Coupling (Giubo)
A critical safety item to check is the flexible driveshaft coupling, often called the Giubo. Ford issued several recalls for this part because the rubber can crack and eventually disintegrate under high torque loads.
If you feel a vibration coming from under the floorboards during acceleration, stop immediately and inspect the coupling. Replacing it is a straightforward DIY job involving a few Grade 8 bolts and a replacement kit from a reputable parts supplier.
I recommend inspecting this coupling every time you change your oil. Look for small “spiderweb” cracks in the rubber; if you see them, the part is reaching the end of its service life.
Suspension and Braking for Heavy Payloads
Stopping a 2017 ford transit 350 passenger van when it is full of passengers requires immense friction and heat management. The factory braking system is robust, but it wears down quickly if you drive aggressively.
When replacing brakes, always opt for heavy-duty ceramic pads. These pads handle high temperatures better than organic alternatives and produce less dust, which keeps your wheels looking cleaner for longer.
Don’t forget to flush your brake fluid every two years. Brake fluid is hygroscopic, meaning it absorbs moisture from the air, which can lower its boiling point and lead to brake fade during long descents.
Maintaining Ride Quality
The rear leaf springs on the Transit 350 are designed for weight, not necessarily for a cloud-like ride. If your van feels excessively bouncy, your rear shocks may be blown.
Upgrading to heavy-duty gas-charged shocks, such as those from Bilstein or Fox, can significantly improve stability. This is especially helpful if you have converted your van into a camper or frequently carry maximum passenger loads.
Check your tire pressures religiously. These vans require Load Range E tires, which often need 75-80 PSI in the rear. Running lower pressures can cause the sidewalls to overheat, leading to a dangerous blowout.
Interior Longevity and Sliding Door Care
The interior of a 2017 ford transit 350 passenger van is built to be durable, but the moving parts require occasional attention. The massive sliding door is the most common point of failure for interior hardware.
The door tracks can collect dirt, salt, and road grime, which increases friction on the rollers. This eventually burns out the door motor or snaps the release cable.
To prevent this, use a vacuum to clean the lower track once a month. Apply a dry silicone lubricant to the rollers and hinges; avoid heavy grease, as it attracts more dirt and creates a grinding paste that wears down the metal.
Managing the Seating Tracks
The Transit uses a rail system for its seats, allowing for various configurations. However, small items like coins or gravel can fall into these tracks and jam the locking mechanism.
If you need to remove seats for extra cargo space, ensure the floor tracks are clear before re-installing them. A seat that isn’t fully clicked into the “locked” position is a major safety hazard in the event of a sudden stop.
For those with the 15-passenger layout, check the rear-most seat bolts periodically. The vibrations from the road can occasionally loosen the mounting hardware on high-mileage units.
Safety Systems and Essential Recalls
Safety is paramount when you are responsible for over a dozen lives. The 2017 ford transit 350 passenger van comes equipped with AdvanceTrac with Roll Stability Control, which is vital for high-roof models.
Ensure that your van’s software is up to date. Ford occasionally releases updates for the Powertrain Control Module (PCM) that improve shifting logic and stability control intervention.
Aside from the driveshaft coupling, check if your van was affected by the fuel pump control module recall. A failing module can cause the engine to stall unexpectedly, which is a terrifying experience on a busy highway.
Tire Pressure Monitoring System (TPMS)
The TPMS in the Transit 350 is calibrated for high-pressure tires. If you swap to off-road tires or different wheels, you may need a specialized TPMS tool to “re-learn” the sensor positions.
Never ignore a TPMS light in this vehicle. Because of the high center of gravity, a low tire can drastically affect your ability to perform an emergency maneuver without tipping.
If you are a DIYer, investing in a basic OBD-II scanner is a great idea. It allows you to read specific codes for the ABS and stability systems that a standard “Check Engine” light might not fully explain.
Frequently Asked Questions About the 2017 Ford Transit 350
What is the towing capacity of a 2017 Ford Transit 350?
When properly equipped, the 2017 Transit 350 can tow up to 7,500 pounds. However, this number decreases as you add more passengers and cargo inside the van, so always check your combined weight ratings.
How often should I change the transmission fluid?
While Ford suggests a long interval, most expert mechanics recommend a “drain and fill” every 60,000 miles. This is especially true if the van is used for stop-and-go city shuttle work, which generates significant heat.
Is the 2017 Ford Transit 350 available in All-Wheel Drive (AWD)?
No, the AWD system was not introduced to the Transit lineup until the 2020 model year. The 2017 models are strictly Rear-Wheel Drive (RWD), though a good set of winter tires can make them quite capable in snow.
What is the most common reason for a “Check Engine” light in this model?
In the 3.5L EcoBoost models, it is often a fouled spark plug or a faulty pressure sensor. In the 3.7L models, an evaporative emissions (EVAP) leak from a loose gas cap or a purge valve is a frequent culprit.
Final Thoughts for the Careful DIYer
Maintaining a 2017 ford transit 350 passenger van is a rewarding experience if you stay ahead of the curve. By addressing the airbox water issues and keeping a close eye on the driveshaft coupling, you can avoid the most common headaches associated with this platform.
Remember that these vehicles are built for work. They thrive on regular use and consistent fluid changes. Whether you are hauling gear for a band or taking the kids to a soccer tournament, a well-maintained Transit is one of the most reliable partners you can have on the road.
