In short, the Ford F-150 uses an ethylene glycol–based engine coolant. The official Ford option is Motorcraft Premium Gold Engine Coolant, or any coolant that is Ford-approved and meets the relevant Ford specification for your model year, typically labeled as compatible with WSS-M97B44-D or WSS-M97B51-A1. Coolant can be used in premixed 50/50 form or as a concentrate that’s diluted to the recommended ratio.
Official specification and recommended products
To ensure proper cooling and warranty coverage, you should use coolant that meets Ford’s specifications. The following options are commonly accepted when explicitly labeled as Ford-approved or meeting Ford’s coolant specification guidelines.
- Motorcraft Premium Gold Engine Coolant (Ford’s official coolant; available premixed or concentrate, diluted per label).
- Any ethylene glycol–based coolant that is explicitly labeled as meeting Ford specification WSS-M97B44-D or WSS-M97B51-A1 (check the product label and your owner's manual for the exact spec for your year).
Using a coolant that carries Ford’s approved specification helps ensure proper corrosion protection, freeze/boilover resistance, and compatibility with the F-150’s cooling system components.
Important guidelines for selecting and mixing coolant
Before you buy or mix coolant, keep these practical guidelines in mind to avoid damage or warranty issues.
- Avoid mixing incompatible coolant types (for example, don’t combine silicate-containing green coolants with Dex-Cool–style orange formulations).
- Prefer a 50/50 premixed coolant or mix a concentrate only according to the label’s dilution instructions.
- Always verify the exact Ford specification listed for your model year in the owner’s manual or with a Ford dealer, since requirements can change between generations.
Adhering to these guidelines helps prevent corrosion, sediment buildup, and cooling-system leaks, and it supports optimal engine temperature management.
Maintenance tips and practical considerations
Beyond choosing the right coolant, it’s smart to follow routine maintenance practices to keep the cooling system in good shape.
- Check the coolant level when the engine is cool and top up with the same specification if needed.
- Inspect hoses, clamps, and the radiator cap for signs of wear or leaks during regular service intervals.
- Flushing or replacing the coolant according to Ford’s recommended intervals (as specified in your manual) helps prevent deposits and corrosion.
Following these maintenance steps can extend the life of the cooling system and reduce the risk of overheating or costly repairs.
Frequently asked questions and quick tips
Here are concise answers to common questions about Ford F-150 coolant compatibility and usage.
- Do I have to use Motorcraft coolant? If you can confirm that an alternative coolant is Ford-approved and meets the correct specification (WSS-M97B44-D or WSS-M97B51-A1), it is acceptable.
- Can I use water to dilute concentrate? Yes, but use distilled water to avoid mineral deposits; follow the label for the exact dilution ratio.
- What color should the coolant be? Color varies by formulation and brand; do not rely on color alone to determine compatibility. Always check the specification on the label and your manual.
Summary
The Ford F-150 uses an ethylene glycol–based coolant that should be Ford-approved, with Motorcraft Premium Gold Engine Coolant as the primary official option. Other coolants that explicitly meet Ford’s specification (WSS-M97B44-D or WSS-M97B51-A1) are acceptable. Always follow the vehicle’s manual for the correct mixture, avoid mixing incompatible types, and perform regular maintenance to ensure the cooling system operates effectively.
