The Ultimate Guide to Choosing the Right Coolant Type for Your Ford Transit
Updated:
Your Ford Transit's cooling system is crucial for maintaining the engine's temperature. For the 3.2L Power Stroke Diesel engine, the capacity of the engine cooling system varies depending on whether your vehicle has an auxiliary heater or not: 15.3 qt (14.5 L) with an auxiliary heater and 13.9 qt (13.2 L) without.
Why the Right Coolant Matters
Choosing the right coolant is not just about filling up the system. The wrong type can cause corrosion, overheating, or even engine failure. And trust me, you don’t want to deal with these issues.
The Right Coolant for Your Transit
According to the service guide, the specified engine coolant for both the U.S. and Mexico is the Motorcraft Orange Antifreeze/Coolant Prediluted (VC-3DIL-B, WSS-M97B44-D2). In Canada, it’s a similar specification (CVC-3DIL-B, WSS-M97B44-D2).
Why Motorcraft Orange?
This particular coolant is designed to meet the specific requirements of your Ford Transit. It helps in preventing corrosion, maintaining optimal engine temperature, and ensuring the longevity of the engine components.

Warnings and Recommendations
- AC Refrigerant Caution: It's important to note that the air conditioning refrigerant system contains R-134a under high pressure, and it's dangerous to handle it without proper training.
- Transmission Fluid: Only use Motorcraft MERCON LV Automatic Transmission Fluid for automatic transmissions. Using the wrong fluid can damage your transmission.
- Oil Specifications: For engine oil, the Motorcraft SAE 5W-40 Full Synthetic Diesel Motor Oil is recommended. Remember, using the correct oil viscosity is crucial for your engine's performance.
Maintenance and Service Intervals
It's vital to change your coolant and other fluids at the right intervals. Regular checks will help you identify when it's time for a change. Refer to your Ford Transit's maintenance schedule for detailed guidance.
DIY or Professional Service?
As a beginner enthusiast, I lean towards recommending professional servicing for tasks like changing coolant. However, if you're well-versed in vehicle maintenance, you can consider a DIY approach. Just ensure you have the right tools and follow safety procedures.
