Adding Coolant To Jeep Wrangler

If you’ve ever driven a Jeep Wrangler, you know that they’re built for off-roading. But what you might not know is that they’re also built for low maintenance. One of the things that makes Jeeps so easy to maintain is that they don’t require much in the way of coolant.

In fact, all you need to do to keep your Jeep’s engine cool is add a little bit of water to the radiator from time to time. That’s right, there’s no need to add antifreeze or any other type of coolant; just plain old water will do the trick. Of course, if you live in an area with very cold winters, you’ll want to use a 50/50 mix of water and antifreeze to prevent the radiator from freezing.

But for most people, adding water is all that’s necessary.

If you’ve ever wondered how to add coolant to your Jeep Wrangler, wonder no more! It’s actually a pretty simple process. Just follow these steps and you’ll be up and running in no time:

1. Park your Wrangler on a level surface and make sure the engine is turned off. 2. Locate the radiator cap on the front of the engine bay. It should be on the driver’s side near the top of the radiator.

3. Remove the radiator cap by unscrewing it counterclockwise. Be careful when doing this, as there may be hot steam or coolant under pressure that could come out when you remove the cap. 4. Once the radiator cap is off, slowly pour coolant into the opening until it reaches the “full” line on the side of the radiator neck.

You can use any type of coolant for this, but we recommend using a 50/50 mix of water and antifreeze for best results. 5 . Replace the radiator cap by screwing it back on clockwise until it’s snugged down tight .

How to Add Coolant to Jeep Wrangler Jl

Adding coolant to your Jeep Wrangler JL is a pretty simple process, but there are a few things you need to know before you get started. Here’s a step-by-step guide on how to add coolant to your Jeep Wrangler JL: 1. Find the coolant reservoir.

It’s usually located near the radiator, and it will have a “full” and “low” line marked on it. 2. Open the reservoir cap and check the level of coolant inside. If it’s below the “low” line, then you need to add more coolant.

3. Pour in the new coolant slowly, so that you don’t overflow the reservoir. Once you reach the “full” line, close the cap and start up your Jeep Wrangler JL to check that everything is working properly.

How Do I Add Coolant to My Jeep Wrangler?

Assuming you are referring to adding coolant to the radiator: Locate the radiator cap on the engine. It will likely have a picture of a radiator or the word “coolant” written on it.

Once you’ve found it, unscrew the cap and set it aside. Find the coolant reservoir and check the level of fluid inside. The reservoir is usually transparent so you can easily see how full it is.

If it’s low, add more coolant until it reaches the “full” line. Be careful not to overfill it as this can cause problems. Now that the coolant reservoir is full, screw the radiator cap back on tight.

Start up your Jeep Wrangler and let it idle for a few minutes so that the new coolant can circulate through properly. Check under the hood periodically to make sure everything looks alright and that there are no leaks.

Can You Just Add Coolant to the Reservoir?

If your car is low on coolant, you may be tempted to just add water to the reservoir. However, this is not a good idea. Water will not mix with the coolant and could actually cause your engine to overheat.

It’s best to add the proper type of coolant/antifreeze to the reservoir. This can usually be found at any auto parts store.

How Do I Know If My Jeep Needs Coolant?

If you notice that your Jeep is starting to overheat, or if the temperature gauge is reading higher than normal, it’s time to check the coolant level. The best way to do this is to remove the radiator cap and look inside. If the coolant level is low, add more until it reaches the full line.

You should also check for leaks in the hoses or radiator. If you see any, have them repaired as soon as possible.

What Coolant Does a Jeep Wrangler Take?

The Jeep Wrangler takes a 50/50 mix of coolant and water. This mixture will provide the best protection for your engine and will help to keep it running at its optimal temperature.

Checking, Filling, and Burping Your Antifreeze


If your Jeep Wrangler is running low on coolant, you can easily add more yourself. Just open the hood and locate the radiator cap. Once you’ve found it, unscrew the cap and add coolant until the reservoir is full.

Be sure to use a 50/50 mixture of water and antifreeze.
