What brake fluid does a 2017 Ford Explorer use?
The 2017 Ford Explorer typically uses a glycol-based brake fluid that meets DOT 3 or DOT 4 specifications (SAE J1703/J1704). Do not use DOT 5 silicone-based fluid. For the exact requirement, always check the brake fluid reservoir cap or the owner's manual.
Official guidance and acceptable fluids
The Ford owner’s manual and the reservoir cap provide the definitive specification. The most common guidance for this model is that either DOT 3 or DOT 4 brake fluid that meets SAE standards is acceptable, with the exact grade shown on the cap. Understanding the difference between DOT grades helps in choosing the right product and avoiding compatibility issues.
- DOT 3: Glycol-based fluid with a lower boiling point; typically adequate for normal driving and cost-conscious replacements.
- DOT 4: Higher boiling point and better performance under heavy braking or hot conditions; widely recommended for newer vehicles and many Ford models.
- DOT 5: Silicone-based fluid that is not compatible with standard ABS systems and is generally not used in a Ford Explorer unless Ford specifies otherwise.
Conclusion: For most 2017 Explorers, either DOT 3 or DOT 4 meeting SAE J1703/J1704 is acceptable, but always verify the exact spec on the reservoir cap or in the manual. Avoid DOT 5 silicone-based fluids unless a vehicle manufacturer explicitly requires it.
Choosing and maintaining brake fluid
To ensure you select the correct fluid and maintain braking performance, follow these steps:
- Check the reservoir cap for the exact DOT specification (for example, DOT 3 or DOT 4) or refer to the owner's manual for the recommended grade.
- Choose a reputable brake fluid that meets the specified DOT rating and is labeled with SAE J1703 (DOT 3) and/or J1704 (DOT 4) compliance.
- Do not mix DOT 5 silicone-based fluid with glycol-based fluids; if your system currently contains glycol-based fluid, continue with glycol-based fluids only unless Ford directs otherwise.
- If the fluid looks dark, contaminated, or has moisture (a test may be advised), plan a brake fluid flush rather than merely topping up.
- Follow the vehicle’s maintenance schedule for brake fluid replacement, typically every 2–3 years, or as recommended by Ford or your technician.
In practice, sticking to the specified DOT grade and performing regular maintenance helps preserve braking performance and protect hydraulic components from moisture-related damage.
What to watch for
Signs that you may need attention include spongy brake feel, reduced braking efficiency, or visible moisture in the fluid. If you’re unsure about the exact specification or need a fluid change, consult a professional technician or a Ford dealership to confirm the correct DOT grade and to perform a proper flush if required.
Summary
For a 2017 Ford Explorer, use a glycol-based brake fluid that meets DOT 3 or DOT 4 standards (SAE J1703/J1704). Do not use DOT 5 silicone-based fluid. Always verify the exact specification on the reservoir cap or in the owner's manual, and follow routine maintenance to ensure optimal braking performance.
