What type of brake fluid for Dodge Journey?

The Dodge Journey typically uses DOT 4 brake fluid, but you should confirm the exact specification for your year and market by checking the owner's manual or the reservoir cap.

Understanding the brake fluid classifications for the Journey

The Journey’s braking system relies on glycol-based fluids. The common classifications you’ll encounter are DOT 3 and DOT 4; DOT 5 silicone-based fluid is generally not compatible with modern ABS-equipped Dodge/Chrysler systems. Using the wrong fluid or mixing grades can reduce braking performance and cause damage over time.

DOT 4 is typically the standard

DOT 4 provides a higher boiling point than DOT 3, which helps maintain braking performance under heavy use and heat. It is compatible with the Journey’s ABS and is the factory-fill for many model years and trims.

When DOT 3 or other fluids come into play

DOT 3 may be specified for certain markets or older inventories; however, most drivers will benefit from DOT 4. If you’re switching from DOT 3 to DOT 4, plan for a full system flush to avoid residual contamination and ensure optimal braking performance.

How to verify the exact specification for your Dodge Journey

To avoid mistakes, verify with the official sources. The following steps help ensure you use the correct brake fluid for your exact vehicle year and market.

Check the brake fluid reservoir cap under the hood for the DOT designation (e.g., DOT 3 or DOT 4) printed on it.

Consult the owner's manual or a dealer service bulletin for your specific year and trim level.

If performing a brake fluid change, use DOT 4 grade and avoid mixing fluids; perform a full system flush if changing DOT grade.

Purchase brake fluid from a reputable brand that meets the DOT 4 specification and the appropriate boiling points for your climate and driving conditions.

Conclusion: The exact specification can vary by year, market, and trim, but DOT 4 is the safe default for most Dodge Journey models, with DOT 3 as a possible alternative only if explicitly specified by the manual. Always verify before topping up or replacing fluid.

Practical tips and maintenance reminders

Best practice is to replace brake fluid every 2-3 years or as recommended by the vehicle’s maintenance schedule, especially if you notice spongy brakes or a drop in braking performance. If you hear grinding or feel vibrations, consult a professional as soon as possible.

Summary

In most Dodge Journey models, DOT 4 brake fluid is recommended due to its higher boiling point and compatibility with ABS. Always confirm the exact spec for your year and market by checking the reservoir cap or the owner's manual, and avoid using DOT 5 silicone-based fluid or mixing different DOT grades unless advised by a dealer.

Do I want DOT 3 or DOT 4 brake fluid?

You should use DOT 3 or DOT 4 brake fluid based on your vehicle's manufacturer specifications, which can be found in your owner's manual. If your car requires DOT 3, you can upgrade to DOT 4 for its higher boiling point, which is beneficial for high-temperature braking or frequent use, but do not use DOT 3 if your car calls for DOT 4.
When to use DOT 3

Daily driving: Most standard cars and trucks use DOT 3 for moderate braking conditions.
If specified: Always use DOT 3 if it is the fluid specified by your vehicle's manufacturer.

When to use DOT 4

For higher performance: DOT 4 has higher boiling points, making it better for high-performance vehicles or situations where brakes are used frequently, like in hilly terrain or towing.
If specified: Some modern vehicles, especially those with ABS systems, may specifically require DOT 4.
Upgrading from DOT 3: If your car currently uses DOT 3, you can upgrade to DOT 4 for improved performance and a higher safety margin. The two are compatible and can be mixed, though it's generally recommended to use the higher-spec fluid if you have the option.

Key differences

Boiling points: DOT 4 has higher dry and wet boiling points than DOT 3, meaning it can withstand higher temperatures before it begins to boil and lose effectiveness.
Moisture absorption: Both fluids are hygroscopic, meaning they absorb moisture over time, which lowers their boiling point. Because DOT 4 has a higher starting boiling point, it has more of a buffer before becoming a safety risk.

Important considerations

Check your manual: Always refer to your car's owner's manual for the correct brake fluid specification to ensure compatibility and prevent system damage.
Do not use lower-spec fluid: Never use a lower-spec fluid (like DOT 3) in a vehicle that requires a higher-spec fluid (like DOT 4).
Do not mix DOT 3 and DOT 5: While DOT 3 and DOT 4 are compatible, DOT 5 is silicone-based and should not be mixed with either glycol-based DOT 3 or DOT 4 fluids.

Is it okay to mix DOT 3 and DOT 4 brake fluid?

Yes, you can mix DOT 3 and DOT 4 brake fluid, as they are chemically compatible, but you should never mix them with DOT 5. Mixing DOT 3 and DOT 4 is acceptable because both are glycol-based. Adding DOT 4 to DOT 3 will lower its boiling point, while adding DOT 3 to DOT 4 will lower its boiling point.

Compatibility and mixing

DOT 3 and DOT 4: These are compatible and can be mixed without causing harm to the braking system.
DOT 3, 4, and 5.1: These are all compatible with each other and can be mixed.
DOT 5: This is silicone-based and is not compatible with DOT 3, DOT 4, or DOT 5.1. Mixing them will cause the system to fail.

What to consider when mixing

Boiling point: DOT 4 has a higher boiling point than DOT 3. Mixing them will lower the overall boiling point of the fluid in your system.
Performance: If your car requires DOT 4 and you mix it with DOT 3, you will reduce the braking system's performance.
Best practice: It is best to check your vehicle's manual and use the specific DOT fluid recommended for your car. If you need to upgrade to DOT 4, it is best to completely flush the old DOT 3 fluid out first to get the full benefits of the DOT 4 fluid.

What brake fluid does a Dodge Journey use?

What are the most popular Brake Fluids for the Dodge Journey? DOT 3 Brake Fluid: Synthetic, Prevents Corrosion, Safe For ABS, Disc, Drum Brakes, 50k miles, 32 oz. DOT 3 Brake Fluid: Synthetic, Prevents Corrosion, Safe For ABS, Disc, Drum Brakes, 50k miles, 12 oz.

What happens if I put DOT 3 instead of DOT 4?

If you put DOT 3 brake fluid in a system that requires DOT 4, the main risk is reduced braking performance in high-heat situations because DOT 3 has a lower boiling point. While the fluids are compatible and mixing them is acceptable in a pinch, it's best to use the manufacturer-recommended fluid to ensure maximum brake safety, especially for high-performance or heavy-duty applications.
What happens

Lower boiling point: DOT 3 has a lower boiling point (205∘C205 raised to the composed with power cap C205∘𝐶 dry, 140∘C140 raised to the composed with power cap C140∘𝐶 wet) compared to DOT 4 (230∘C230 raised to the composed with power cap C230∘𝐶 dry, 155∘C155 raised to the composed with power cap C155∘𝐶 wet).
Potential for brake fade: In situations like descending a long, steep hill or aggressive driving, the brake fluid can get hot enough to boil. DOT 3 is more likely to reach its boiling point than DOT 4, which can cause a spongy brake pedal and loss of braking power (brake fade).
Incompatibility with DOT 5: DOT 3 is not compatible with silicone-based DOT 5 fluid. Never mix DOT 3, 4, or 5.1 with DOT 5 fluid, as this can damage the brake system.

What to do

Use the correct fluid: Always use the specific type of brake fluid recommended by your vehicle's manufacturer for safety and optimal performance.
If you mixed them: If you've accidentally mixed the two, it's not an immediate emergency for normal driving, but it's recommended to have the system flushed and refilled with the correct DOT 4 fluid. This will ensure you have the higher temperature safety margin that was originally specified for your car.
Wipe up spills: Brake fluid can damage paint. Be sure to wipe up any spills immediately.
