Owning a 2019 ford transit 150 means you have one of the most flexible platforms in the automotive world. Whether you are hauling tools to a job site or building a custom camper for weekend getaways, this van offers the reliability you need. However, keeping it in top shape requires more than just occasional oil changes.
Many owners feel overwhelmed by the modern technology and tight engine bays found in these vehicles. This article breaks down the complex systems into manageable DIY tasks that any motivated owner can handle. We will focus on the specific needs of the 2019 model year to keep your engine humming and your cargo safe.
Our goal is to empower you with the knowledge to diagnose problems before they become expensive repairs. From understanding your engine options to optimizing your suspension, we cover the essentials of preventative maintenance and performance. Let’s get under the hood and see what makes your Transit tick.
Understanding Your Engine: 3.5L EcoBoost vs. 3.7L Ti-VCT
The 2019 model year offered two primary gasoline engines, each with its own maintenance profile. Knowing which one sits under your hood is the first step in proper care. The 3.7L V6 is a naturally aspirated workhorse known for its longevity and simplicity.
If you have the 3.5L EcoBoost, you are dealing with a twin-turbocharged engine that provides significant torque. While powerful, the EcoBoost is more sensitive to oil quality and spark plug gaps. Turbocharged engines generate more heat, which can break down conventional oil faster than standard engines.
Regardless of the engine, regular inspections are vital for the 2019 ford transit 150. Check your air filter every 15,000 miles, especially if you drive in dusty environments or on gravel roads. A clogged filter starves the engine of oxygen, reducing your fuel economy and power output.
Turbocharger Care for the 3.5L EcoBoost
If your van has the EcoBoost engine, you must be diligent about your cooling system. The turbos are water-cooled, meaning any drop in coolant levels can lead to catastrophic failure. Always use the Orange OAT coolant specified by Ford to prevent internal corrosion.
Avoid “hot shutdowns” after a long highway haul or a steep mountain climb. Let the engine idle for 60 seconds before turning it off. This allows oil to circulate and cool the turbo bearings, preventing oil coking which can ruin the assembly.
Common Issues to Watch in the 2019 ford transit 150
Every vehicle has its quirks, and the Transit is no exception. One of the most discussed components among high-mileage owners is the driveshaft flex disc, often called the “guibo.” This rubber coupling can crack over time, leading to vibrations felt through the floorboards.
Inspect the flex disc during every oil change for signs of tearing or dry rot. If you feel a shudder during acceleration, this is the first place to look. Replacing it early prevents damage to the transmission output shaft or the rear differential.
Another area of concern is the “water shedding” issue from the windshield cowl. In heavy rain, water can sometimes leak onto the engine cover and seep into the spark plug wells. This often causes a persistent misfire that is difficult to diagnose without removing the intake manifold.
Brake System Longevity and Pulsation
The Transit 150 is a heavy vehicle, and the brakes work hard to bring it to a stop. Many owners report brake pulsation, which usually indicates warped front rotors. This often happens if the lug nuts are over-torqued or if the brakes overheat during heavy hauling.
When replacing pads, always use a high-quality ceramic compound to reduce dust and noise. Ensure you clean the caliper slide pins and lubricate them with high-temp silicone grease. This ensures the pads wear evenly and prevents the calipers from sticking.
Electrical Gremlins and Battery Health
The 2019 model features a complex electrical system that can be sensitive to low voltage. If you notice strange dashboard warnings or flickering lights, check your battery terminals for corrosion. A weak battery can cause the computer modules to behave erratically.
If you have added aftermarket accessories like a 12V fridge or extra lighting, consider upgrading to an AGM battery. These handle deep cycles better than standard lead-acid batteries. Always use a battery maintainer if the van sits for more than a week.
Essential Fluids and Filters for Longevity
Maintaining your 2019 ford transit 150 starts with using the correct fluids. Ford recommends 5W-20 for the 3.7L engine and 5W-30 for the 3.5L EcoBoost. Using a full synthetic oil is highly recommended to protect the internal timing chains.
Do not ignore the transmission fluid in the 6R80 six-speed automatic. While Ford claims it is “filled for life,” most mechanics suggest a drain and fill every 60,000 miles. This removes metal shavings and restores the detergent package in the fluid.
- Engine Oil: Change every 5,000 to 7,500 miles depending on load.
- Engine Coolant: Flush and replace every 100,000 miles or 6 years.
- Brake Fluid: Test for moisture content every 2 years; flush if necessary.
- Differential Fluid: Inspect for leaks; change every 150,000 miles for normal use.
The Importance of the Fuel Filter
The fuel filter on these vans is integrated into the fuel pump assembly inside the tank. While it isn’t a “serviceable” part in the traditional sense, using Top Tier gasoline helps. Low-quality fuel can clog the fine mesh screen, leading to lean codes and poor performance.
If you experience stalling or hard starts, have a technician perform a fuel pressure test. If the pressure is low, the entire pump assembly may need replacement. Keeping your tank above a quarter-full helps keep the pump cool and submerged.
Suspension and Handling Upgrades
The factory suspension on a 2019 ford transit 150 is designed for a compromise between comfort and load carrying. However, if you have converted your van into a camper, the weight is constant. This can lead to a “wallowy” feel or excessive swaying in crosswinds.
Upgrading to heavy-duty rear shocks, such as those from Bilstein or Fox, can transform the ride quality. These shocks offer better damping, which keeps the tires in contact with the road. This is especially important when navigating washboard dirt roads or technical terrain.
SumoSprings or Timbren SES kits are excellent “set it and forget it” upgrades for the rear axle. These act as progressive helper springs that engage when the van is loaded. They reduce sag and improve stability without the complexity of an air bag system.
Tire Selection for Off-Road and Highway
Your tires are the only thing connecting your van to the pavement. For the Transit 150, look for tires with an “E” load rating. These have stiffer sidewalls that can handle the high center of gravity and heavy payloads typical of these vans.
If you spend time off-pavement, consider an All-Terrain tire like the BFGoodrich KO2. These provide better traction in mud and snow while maintaining decent highway manners. Remember to rotate your tires every 5,000 miles to ensure even tread wear.
Safety Inspections for the DIY Mechanic
Safety is paramount when working on a vehicle as large as the Transit. Always use heavy-duty jack stands rated for at least 3 tons. Never rely solely on a floor jack when crawling underneath the chassis to inspect the fuel lines or exhaust.
Check your lighting system monthly, including the high-mount brake light. The 2019 model uses a mix of LED and halogen bulbs. Replacing a burnt-out headlight is straightforward, but accessing the rear tail light housings requires a T25 Torx driver.
- Park on a level surface and engage the parking brake.
- Inspect the serpentine belt for cracks or fraying.
- Check the tire pressure, including the spare tire tucked under the rear.
- Look for fluid leaks around the oil pan and transmission bell housing.
Checking the Serpentine Belt and Pulleys
A snapped belt will leave you stranded and can cause the engine to overheat instantly. Listen for squealing sounds during a cold start, which indicates a worn belt or a failing tensioner. If the belt looks glazed or shiny, it is time for a replacement.
While the belt is off, spin the idler pulleys by hand. They should spin smoothly without any grinding noise or lateral play. Replacing a $20 pulley now is much cheaper than a tow truck bill later.
Maximizing Interior Utility and Comfort
The cabin of the 2019 ford transit 150 is a functional space, but it can be improved. Adding sound deadening material to the door panels and wheel wells significantly reduces road noise. This makes long highway stints much less fatiguing for the driver.
For those using the van for work, installing a bulkhead partition is a critical safety move. In the event of a sudden stop, the bulkhead prevents tools and cargo from flying into the cab. It also helps the HVAC system heat or cool the smaller cabin area faster.
If your van serves as a mobile office, consider an inverter system. This allows you to charge laptops and power tools using the van’s alternator. Ensure you use a fused circuit and heavy-gauge wire to prevent electrical fires.
Frequently Asked Questions About 2019 ford transit 150
What is the towing capacity of the 2019 ford transit 150?
The towing capacity varies depending on the engine and axle ratio, but it generally ranges between 5,000 and 7,500 pounds. Always check the door jamb sticker for your specific vehicle’s Gross Combined Weight Rating (GCWR) before hitching up a trailer.
How often should I change the spark plugs?
For the 3.7L engine, Ford recommends 100,000 miles. However, for the 3.5L EcoBoost, many experts suggest changing them every 40,000 to 50,000 miles. The higher cylinder pressures in the turbo engine can wear down the electrode gap faster, leading to misfires.
Does the 2019 Ford Transit 150 have a timing belt or chain?
Both the 3.5L and 3.7L engines use a timing chain rather than a belt. These are designed to last the life of the engine. However, they rely on clean oil for lubrication, so skipping oil changes can lead to chain stretch and expensive timing issues.
Why is my “Change Oil Soon” light on before 7,500 miles?
The Transit uses an Intelligent Oil-Life Monitor. It calculates oil life based on idling time, ambient temperature, and load. If you do a lot of city driving or heavy hauling, the computer will trigger the light earlier to protect the engine internals.
Final Thoughts on Transit Ownership
Taking care of your 2019 ford transit 150 is an investment in your productivity and freedom. By following a strict maintenance schedule and addressing minor issues like the flex disc or brake rotors early, you can easily see 200,000 miles or more from this platform. Remember that safety always comes first; if a job feels beyond your skill level, do not hesitate to visit a certified technician.
Whether you are navigating tight city streets or exploring remote forest service roads, a well-maintained van is a joy to drive. Keep your fluids fresh, your tires rotated, and your eyes on the road. Stay safe and enjoy the journey in your Ford Transit!
