We will explore everything from engine options and fluid specifications to common sliding door fixes and off-road suspension setups. Follow these expert tips to ensure your van remains a dependable workhorse or the ultimate adventure rig.
Understanding the 2020 Powertrain Options
The 2020 model year brought major changes to the Transit lineup, most notably the retirement of the 3.7L V6 and the 3.2L Diesel. In their place, Ford introduced two distinct 3.5L engines designed for better efficiency and torque.
The base engine is the 3.5L PFDI (Port Fuel and Direct Injection) V6, which offers a balance of reliability and fuel economy. It produces 275 horsepower and is ideal for standard shuttle duties or light-duty hauling.
For those needing more muscle, the 3.5L EcoBoost V6 provides 310 horsepower and a massive 400 lb-ft of torque. This twin-turbocharged engine is the preferred choice for heavy towing and high-altitude mountain climbs.
The 10-Speed SelectShift Transmission
Both engines pair with Ford’s 10-speed automatic transmission, which replaced the older 6-speed unit. This gearbox keeps the engine in its power band more effectively, improving both acceleration and highway cruising.
Check your transmission fluid levels regularly, though be aware that many 2020 models lack a traditional dipstick. You may need to use the specialized level-check plug located on the side of the transmission case.
Intelligent All-Wheel Drive (AWD)
One of the most exciting features of the 2020 model is the optional AWD system. Unlike traditional 4WD, this system constantly monitors traction and can send up to 100% of available torque to the front wheels.
If you plan on taking your van off-road, ensure the AWD software is up to date. Ford occasionally releases updates to refine how the system handles deep sand or icy conditions.
Critical Maintenance for the 2020 ford transit 350 passenger van
Routine service is the most effective way to prevent costly repairs down the road. Because these vans often operate under “severe duty” conditions, following a strict schedule is paramount.
Change your engine oil every 5,000 to 7,500 miles, depending on your driving habits. Use a high-quality full synthetic 5W-30 oil to protect the turbochargers on EcoBoost models and ensure cold-start lubrication.
Inspect your cooling system frequently, as the Transit engine bay can get quite hot during long hauls. Ensure the coolant level in the degas bottle stays between the “Min” and “Max” marks when the engine is cold.
Brake System Care
A 2020 ford transit 350 passenger van carries significant weight, which puts immense stress on the braking system. Inspect your brake pads every time you rotate your tires to check for uneven wear.
Use heavy-duty ceramic brake pads to reduce fade during long descents. If you notice a pulsating feeling in the pedal, your rotors may be warped and will require machining or replacement.
Air Filter Maintenance
Do not overlook the engine air filter, especially if you drive on dusty trails. A clogged filter starves the engine of air, reducing fuel economy and increasing wear on the internal components.
The cabin air filter is equally important for passenger comfort. It is located behind the glovebox and should be replaced every 15,000 miles to keep the HVAC system smelling fresh and working efficiently.
Common DIY Fixes and Troubleshooting
Even the most reliable vans encounter issues over time, but many common Transit problems are easy to fix with basic tools. Identifying these early can save you a trip to the dealership.
One frequent complaint involves the power sliding door, which may fail to close properly or feel “sticky.” This is often caused by dirt buildup in the lower door track or a misaligned latch.
Clean the tracks with a damp cloth and apply a small amount of dry silicone lubricant to the rollers. Avoid using heavy grease, as it attracts dirt and will eventually make the problem worse.
Addressing Water Ingress
Some owners report water leaking into the cabin from the roof area or the front cowl. Check the plastic cowl drains at the base of the windshield to ensure they are not blocked by leaves or debris.
If water is entering from the roof, inspect the plastic plugs that cover the roof rack mounting points. Applying a small bead of automotive-grade sealant around these plugs can prevent interior damage.
Electrical and Battery Health
Modern Transits are packed with electronics, which can put a heavy load on the battery. If you notice sluggish cranking or flickering interior lights, test your battery’s cold cranking amps (CCA).
The battery is located under the driver’s seat, which makes it slightly more difficult to access than a standard engine-bay battery. You will need to slide the seat forward and remove the protective cover to reach the terminals.
Optimizing for Off-Road and Adventure
The 2020 Transit has become a favorite for “van life” builders and off-roaders thanks to the AWD option. However, the factory ground clearance is somewhat limited for serious trail work.
Consider installing a 2-inch suspension lift kit to provide better approach and departure angles. Companies like Van Compass offer specialized kits that maintain factory ride quality while adding much-needed height.
Upgrading your shocks to heavy-duty units, such as those from Falcon or Bilstein, will significantly improve handling on washboard roads. These shocks are designed to dissipate heat better than the stock components.
Tire Selection for Versatility
The stock tires are designed for highway efficiency and low noise, but they struggle in mud or snow. Switching to an All-Terrain (A/T) tire will transform the capability of your van.
Look for tires with the Three-Peak Mountain Snowflake (3PMSF) symbol if you plan on driving in winter conditions. This ensures the rubber compound remains flexible and grippy in freezing temperatures.
Protecting the Underside
The undercarriage of the Transit has several vulnerable components, including the oil pan and the fuel tank. Installing aluminum skid plates is a smart investment for any off-roader.
Skid plates provide a smooth surface to slide over obstacles and prevent sharp rocks from puncturing vital systems. Focus on protecting the transfer case if your van is equipped with AWD.
Safety Systems and Driver Assistance
Ford equipped the 2020 Transit with a suite of safety technologies known as Co-Pilot360. This includes Pre-Collision Assist, Automatic Emergency Braking, and Lane-Keeping System.
These systems rely on a camera mounted behind the rearview mirror and radar sensors in the front bumper. Keep your windshield clean and ensure the sensors are free of snow or mud to maintain functionality.
If you install a large brush guard or a winch bumper, make sure it does not obstruct the radar sensor. Many aftermarket manufacturers offer relocation kits to keep your safety systems active.
Towing with Confidence
When towing a trailer with your 2020 ford transit 350 passenger van, always stay within the Gross Combined Weight Rating (GCWR). Overloading the van can lead to transmission overheating and brake failure.
Utilize the “Tow/Haul” mode on your gear selector to alter the transmission shift points. This provides better engine braking when heading downhill and prevents the transmission from “hunting” for gears on inclines.
Ensure your trailer is equipped with functioning electric brakes. The Transit often comes pre-wired for a brake controller, which allows you to adjust the trailer’s braking force from the driver’s seat.
Frequently Asked Questions About the 2020 ford transit 350 passenger van
