Routine Fluid Checks and Changes
Engine Oil: Check your engine oil level regularly, especially before long trips or heavy towing. For the 6.7L Power Stroke, use only CJ-4 or CK-4 rated diesel engine oil.
Change oil and filter according to the intelligent oil-life monitor or every 7,500 to 10,000 miles, depending on usage. Always use a high-quality oil filter.
Coolant: Maintain proper coolant levels using the specified Motorcraft Orange Antifreeze/Coolant. Check for leaks around hoses and the radiator. Transmission Fluid: The TorqShift transmission requires specific Mercon LV fluid. Check the fluid level with the engine warm and running, following the dipstick instructions carefully. Differential Fluids: Front and rear differentials need periodic fluid changes, especially if you engage in heavy towing or off-roading. Consult your owner’s manual for specific intervals and fluid types.
Tire Care and Suspension Inspection
Tire Pressure: Proper tire pressure is critical for safety, fuel economy, and tire longevity. Check all tires, including the spare, at least once a month using a reliable tire pressure gauge.
Refer to the tire placard on your driver’s side door jamb for the correct cold inflation pressures. Rotate your tires every 5,000 to 7,500 miles to promote even wear. Suspension Components: Regularly inspect your suspension for worn ball joints, tie rod ends, and bushings. Look for signs of fluid leaks from shock absorbers.
Listen for unusual noises like clunks or squeaks over bumps, which can indicate worn components. Address these issues promptly to maintain ride quality and safety.
Brake System Maintenance
Brake Pad and Rotor Inspection: Visually inspect your brake pads for wear every oil change. Look for cracks or warping on the brake rotors.
Heavy-duty trucks like the F-350 put immense strain on brakes. Replace pads and rotors before they reach minimum thickness to prevent reduced stopping power and potential damage.
Brake Fluid: Check the brake fluid level and condition. Brake fluid should be clear; dark or cloudy fluid may indicate contamination and warrant a flush.
Bleed the brake lines if you notice a spongy pedal feel. Always use the specified DOT 4 brake fluid.
Troubleshooting Common Issues with Your Super Duty
Even the most robust vehicles can encounter problems. Knowing how to diagnose and address common issues can save you time and money.
This section provides practical steps for identifying and resolving typical challenges with your F-350. Remember to prioritize safety and consult a professional when in doubt.
Diesel Engine Specific Problems (6.7L Power Stroke)
DEF System Issues: The Diesel Exhaust Fluid (DEF) system is vital for emissions compliance. Common issues include clogged DEF injectors, faulty DEF pumps, or contaminated DEF.
If you get a “Low DEF” warning, refill immediately. If a “DEF System Malfunction” light appears, it often requires dealer diagnosis. Do not ignore these warnings, as they can lead to power derates.
Fuel Filter Replacement: The 6.7L Power Stroke has two fuel filters that require regular replacement. Neglecting this can lead to fuel system damage and reduced engine performance.
Replace both the frame-mounted and engine-mounted fuel filters every 15,000 to 20,000 miles, or as recommended by Ford. Keep a spare set if you travel to remote areas. Exhaust Regeneration: Diesel particulate filters (DPF) need to regenerate to burn off soot. If you primarily do short trips, the truck may not complete regeneration cycles, leading to DPF clogging.
If your truck indicates a “Drive to Clean Exhaust Filter” message, take it for a sustained drive at highway speeds until the message clears. This helps the DPF complete its regeneration cycle.
Electrical and Infotainment Glitches
SYNC 3 Freezing/Lagging: Modern infotainment systems can occasionally freeze or become unresponsive. Often, a soft reset can resolve these issues.
To perform a soft reset, hold the Power button (usually part of the volume knob) and the Seek Right button simultaneously for about 10 seconds. The system should restart.
Battery Drain: If your battery consistently dies, check for parasitic drains. Ensure all interior lights, accessories, and aftermarket devices are off when the truck is parked.
A weak battery or corroded battery terminals can also cause starting issues. Clean terminals and test battery voltage regularly, especially in extreme temperatures.
Suspension and Steering Noises
“Death Wobble”: While less common in newer F-Series trucks, the “death wobble” (violent shaking of the front end) can still occur, often due to worn steering components.
Inspect track bar bushings, tie rod ends, ball joints, and steering damper. Any play in these components needs immediate attention from a qualified mechanic. Squeaks and Groans: Lubricate suspension bushings and leaf springs if you hear squeaks. Dry universal joints (U-joints) in the driveshaft can also cause groaning noises.
Use a grease gun to apply appropriate grease to all accessible zerks. This simple step can eliminate many common noises and extend component life.
Performance Upgrades: Unleashing More Power
The 2019 F-350 is powerful, but there’s always room for improvement. Performance modifications can enhance towing, off-road capability, or simply make your truck more enjoyable to drive.
Approach modifications thoughtfully, considering your primary use case and potential impact on warranty or emissions. Always choose reputable brands and professional installation when necessary.
Engine Tuning and Air Intake Systems
Engine Tuners/Programmers: A performance tuner can optimize your engine’s fuel delivery, timing, and turbo boost. This can significantly increase horsepower and torque, especially for the 6.7L Power Stroke.
Choose tuners that offer multiple power levels, including options for towing and fuel economy. Be aware that some tuners may void your warranty or affect emissions compliance. Cold Air Intakes: A high-flow cold air intake system can improve engine breathing by allowing more cool, dense air into the engine. This can result in modest gains in horsepower and torque.
Look for systems that are fully sealed to prevent hot engine bay air from being ingested. Regular filter cleaning or replacement is essential for maintaining performance.
Exhaust System Upgrades
Aftermarket Exhaust: Upgrading to a less restrictive exhaust system can improve exhaust gas flow, potentially leading to slight power gains and a more aggressive exhaust note.
For diesel trucks, be mindful of emissions regulations. “Delete” kits that remove emissions components are illegal for street use in most areas and will void your warranty.
Consider a cat-back or DPF-back system for a legal and noticeable improvement in sound and flow. These systems typically replace only the components downstream of the DPF.
Off-Road Preparation and Safety for Your F-350
The 2019 ford f 350 super duty lariat crew cab 4wd is a formidable machine for off-road adventures, especially with its robust 4×4 system. Proper preparation is key to a safe and enjoyable experience.
Never venture off-road unprepared. Knowing your truck’s limits and having the right gear can prevent dangerous situations. Always tell someone your route and expected return time.
Suspension Lifts and Larger Tires
Lift Kits: A quality lift kit increases ground clearance, allowing you to clear larger obstacles. It also enables the fitment of larger, more aggressive off-road tires.
Choose a lift kit that maintains proper suspension geometry and ride quality. Consult with experienced off-road shops for recommendations and professional installation. Off-Road Tires: Aggressive all-terrain (A/T) or mud-terrain (M/T) tires provide superior traction on dirt, mud, and rocks. They are essential for serious off-roading.
Ensure your chosen tires are load-rated for your F-350’s weight. Consider beadlock wheels for extreme low-pressure crawling, but be aware of their street legality.
Recovery Gear and Safety Essentials
Recovery Kit: A basic recovery kit should include a heavy-duty recovery strap (not a tow strap), D-ring shackles, a shovel, and work gloves. A winch is a valuable addition for solo adventures.
Learn proper recovery techniques. Improper use of recovery gear can be extremely dangerous. Always stand clear of tensioned lines.
First Aid and Communication: Carry a well-stocked first-aid kit and know how to use it. A satellite messenger or two-way radio is crucial for communication in areas without cell service.
Pack extra water, food, and warm clothing. Conditions can change rapidly, especially in remote wilderness areas.
Off-Road Driving Techniques and Etiquette
Engage 4WD Correctly: Know when to use 4-High for moderate trails and 4-Low for steep inclines, deep mud, or technical crawling. Engage the rear differential lock for maximum traction when needed.
Never engage 4WD on dry pavement, as it can damage the drivetrain. Disengage 4WD once you return to improved surfaces.
Trail Etiquette: “Tread Lightly!” means staying on designated trails, packing out everything you pack in, and respecting wildlife. Drive slowly and be mindful of other trail users.
Assess obstacles before attempting them. If you’re unsure, scout the path on foot. When in doubt, turn around; it’s always better to be safe than sorry.
