2019 Ford Transit — Fluid Type Specs

Quick reference

Engine Oil

The 2019 Ford Transit offers a range of engine options, each with specific oil requirements. It's crucial to check your owner's manual for the exact capacity and specification for your particular engine. All capacities are approximate and should be verified with the dipstick.

Gasoline Engines (3.7L Ti-VCT V6, 3.5L EcoBoost V6)

• Type: SAE 5W-30 Premium Synthetic Blend Motor Oil
• Specification: Ford WSS-M2C946-B1 (API SN or higher, with resource conserving designation)
• Capacity:
  • 3.7L Ti-VCT V6: Approximately 6.0 quarts (5.7 liters)
  • 3.5L EcoBoost V6: Approximately 6.0 quarts (5.7 liters)

Diesel Engine (3.2L Power Stroke I5)

• Type: SAE 5W-30 Premium Diesel Motor Oil
• Specification: Ford WSS-M2C934-B (API CJ-4 or FA-4 compatible)
• Capacity: Approximately 11.5 quarts (10.9 liters)

Notes on Intervals and Pitfalls: Ford generally recommends oil change intervals of 7,500 to 10,000 miles or every 6-12 months, whichever comes first. However, severe duty cycles (heavy towing, extreme temperatures, extensive idling) may necessitate more frequent changes. Always refer to your owner's manual for the Intelligent Oil-Life Monitor (IOLM) recommendations. Using an oil that does not meet the specified Ford WSS-M2C946-B1 or WSS-M2C934-B can lead to premature wear, reduced fuel economy, and potential engine damage. Never mix gasoline and diesel engine oils, as their additive packages are significantly different.

Engine Coolant

• Type: Ford/Motorcraft Orange Antifreeze/Coolant (Pre-diluted or Concentrate)
• Specification: Ford WSS-M97B44-D. This is an Organic Acid Technology (OAT) coolant.
• Color: Orange
• Capacity:
  • Gasoline Engines: Approximately 13.5 - 14.5 quarts (12.8 - 13.7 liters)
  • Diesel Engine: Approximately 14.6 - 15.6 quarts (13.8 - 14.8 liters)

Notes on Intervals and Pitfalls: Ford recommends inspecting coolant levels and condition through every service interval. The manufacturer-recommended service interval for this coolant is typically 10 years or 200,000 miles, whichever comes first. The most critical pitfall with Ford's orange OAT coolant is mixing it with incompatible coolants, especially older green (inorganic additive technology, IAT) or yellow/gold (hybrid organic additive technology, HOAT) types. Mixing can lead to silicate dropout, gel formation, and corrosion, severely compromising the cooling system's efficiency and potentially causing major engine damage. Always use Motorcraft Orange or an equivalent coolant that explicitly meets Ford WSS-M97B44-D.

Transmission Fluid

The 2019 Ford Transit utilizes the Mercon LV specification for its automatic transmissions.

• Type: Mercon LV Automatic Transmission Fluid
• Specification: Ford Mercon LV
• Capacity: Varies significantly based on transmission model and whether it’s a drain and fill or a complete overhaul/flush. Typically ranges from 6-8 quarts for a drain and fill, but can be 13-17 quarts for a full system flush. Always refer to the owner's manual or OEM service information.
