In most Ranger models, the proper coolant is a Ford OEM long-life ethylene glycol-based coolant that meets Ford specification WSS-M97B44-D (and newer WSS-M97B44-D2). It is typically sold as Motorcraft Premium Engine Coolant in premixed 50/50 form or as concentrate, depending on region and engine. Always verify the exact specification for your year and market.
Understanding the Ranger's coolant specification
The coolant used in a Ford Ranger is defined by a Ford-approved specification rather than a single universal color or brand. While Motorcraft-brand coolants that meet WSS-M97B44-D (and D2) are commonly recommended, exact formulations can vary by engine type and regional availability. Always consult the owner's manual or a Ford dealer to confirm which product is compatible with your specific Ranger.
Key points about choosing the right coolant
Before considering options, keep these guidelines in mind:
- Use a coolant that meets Ford specification WSS-M97B44-D (and WSS-M97B44-D2 where applicable).
- Choose a long-life ethylene glycol-based coolant, preferably OEM-approved (e.g., Motorcraft Premium Engine Coolant) or an equivalent that explicitly states compatibility with Ford's spec.
- Decide between premixed 50/50 coolant and concentrate as directed by the product and your manual.
- Avoid mixing incompatible coolants or those not rated for Ford specifications to prevent cooling-system issues.
Concluding: For Ranger models, the correct coolant is defined by Ford’s WSS-M97B44-D standard, with Motorcraft Premium Engine Coolant or an OEM-approved equivalent as a typical option. Always verify the exact specification for your particular vehicle.
Practical steps to verify or replace the coolant
When checking or replacing the Ranger’s coolant, follow these steps to ensure you use the right product and maintain proper cooling-system performance:
- Consult the owner’s manual or contact a Ford dealer to confirm the exact coolant specification for your model year and market.
- Look for a coolant product that explicitly meets WSS-M97B44-D (and D2, if listed for your vehicle).
- Decide between premixed 50/50 coolant or concentrate per the product instructions and regional guidelines.
- Do not mix incompatible coolant types; if you’re unsure about what’s currently in the system, consider a full drain and refill with the correct specification.
- Follow the recommended service intervals for coolant replacement and system flushes as outlined in the manual.
Concluding: Verifying the Ford specification and using an approved product helps ensure reliable cooling system performance across Ranger generations.
Summary
The Ford Ranger typically uses a long-life ethylene glycol-based coolant that meets Ford specification WSS-M97B44-D (and WSS-M97B44-D2 in some cases), commonly available as Motorcraft Premium Engine Coolant. Since exact requirements can vary by engine, year, and market, always check the owner’s manual or with a dealer for the precise coolant type and mixing guidelines.
