Your Jeep Wrangler fluid type capacity plays a vital role in the proper functioning of the braking system so read the article to learn which and how much fluid you should fill in your Jeep.
Do you think that the proper functioning of your vehicle’s braking system solely depends on the regular maintenance of its hydraulic components? Well, that’s not the complete truth since brake fluid type and capacity also play a vital role.
Each car model is designed to work perfectly with a particular fluid type since all the internal components of its braking system are tested and selected to work optimally with that certain fluid type.
On using the wrong brake fluid or not filling the brake fluid to the required level, many operation-related problems may arise such as overheating, poor lubrication, and transmission failure. The worst part is that not even an expert mechanic could reverse the damage done by the wrong fluid type. Therefore, it’s critical to do thorough homework and find out about the best brake fluid and capacity for your Jeep Wrangler.
We have done all the legwork for you and jotted down all the valuable information about your jeep wrangler brake fluid type capacity. So just dive into the article and make sure you’re not putting your road safety at risk by neglecting the importance of correct brake fluid and capacity! Shall we begin?
Correct brake fluid type for jeep Wrangler
The American department of transportation has classified brake fluid into four major categories; DOT 3, DOT 4, DOT 5, and DOT 5.1. All of these fluid types are different from each other based on their composition and dry & wet boiling points as follows;
|Wet boiling point||Dry boiling point||Composition|
|DOT 3||140°C or 284°F||205°C or 401°F||Glycol ether|
|DOT 4||155°C or 311°F||230°C or 446°F||Borate ester/Glycol ether|
|DOT 5||180°C or 356°F||260°C or 500°F||Silicone|
|DOT 5.1||180°C or 356°F||260°C or 500°F||Glycol ether/Borate ester|
In most vehicles, DOT 3 fluid type is commonly used. However, DOT 4 fluid type is gaining popularity due to its amazing traction control. Also, it is preferably used in anti-locking braking systems due to its low viscosity and higher boiling point.
On the other hand, DOT 5.1 fluid type is used in heavy-duty and high-performance vehicles due to its incredibly high boiling points. Both the DOT 3 and DOT 4 fluids are compatible and can be interchanged. DOT 5.1 is also compatible with DOT 4 & DOT 3.
Speaking of the DOT 5 fluid type then it’s most unique as it absorbs almost negligible amounts of moisture. Considering this, it’s also not compatible with the rest of the fluid types and is mostly used in antique, classic cars.
If you own a third-generation 2018 jeep wrangler, we recommend you go with either DOT 3 or DOT 4 brake fluid.
Jeep Wrangler brake fluid capacity
Unfortunately, the capacities for brake fluid in jeep wranglers don’t follow the one-size-fits-all rule. Depending upon the make, model, and year, the fluid capacity may vary for your Jeep Wrangler. Thus, to keep your vehicle running in the best condition, it’s essential to keep the fluid level within an optimal range.
Also, it’s important to keep checking the fluid level and refill the missing fluid to avoid any inconvenience in the near future. Generally, the brake fluid capacity of a wrangler model depends upon the type of engine installed in it. Below, we’ve mentioned the fluid type and capacity of some famous jeep wrangler models;
|Fuel type||Engine type||Brake Fluid type||Fluid capacity|
|Jeep gasoline||V6 3.8L EGT 196HP||DOT 3, DOT 4||1.25 L|
|Jeep diesel straight||4 2.8L ENS 174 HP||DOT 3, DOT 4||1.25 L|
|Jeep diesel straight||4 2.8L ENS 197 HP||DOT 3, DOT 4||1.25 L|
|Jeep gasoline||V6 3.6L ERB 280 HP||DOT 3, DOT 4||1 L|
Generally, replacing the old brake fluid costs around $50-$100 but you can save this amount by replacing the fluid yourself. The whole process takes around twenty to forty minutes and doesn’t require any special skill or tool. The information regarding the fluid type and fluid capacity mentioned in this article is approximate so it’s better to check the owner’s manual before changing or refilling brake fluid.
Brake Fluids tend to last around 40,000 kms. On average, the brake fluid needs to be changed every one or two years. Which is better, DOT 3 or DOT 5? DOT 5 is considered better than DOT 3 since it has a high boiling point and doesn’t let any moisture get in it over time. Considering this, DOT 5 tends to last longer than DOT 3. What are the symptoms of old brake fluid? As brake fluid ages, it gets much more difficult to press brake pads and brake pedals. Also, you might notice a harsh, burning smell. Some newer vehicles also have indicator lights for anti-lock braking systems which illuminate on low fluid levels.
