Here is a list of how to fix an exhaust leak without welding the area. You can do these all on your own! Check them out!

Methods of How to Fix an Exhaust Leak without Welding

Using Adhesive

This method for fixing the leaks of the exhaust is designed for smaller leaks. All you need to do is fill up the holes with the help of epoxy and you are done! If you are new to using epoxy to get rid of the exhaust leak, let us help you out! Have a look at the following steps to learn how to fix the exhaust leak without welding.

Step 1: Find the Leak

More of the fixing process depends on where the leak on your exhaust is. If you are unable to find where the leak is, adding epoxy will be of no good! Now, keep in mind that whenever you require patching the pipe, epoxy cannot help you out. It will only fit for the smaller leaks. Now, your job is to find the smaller leaks first. If you see that there are leaks on the exhaust that are 5 mm or smaller, epoxy can be highly helpful for you!

Step 2: Cleaning and Sanding

Now that you have learned you can clean the exhaust leak with the help of epoxy, you have to start by cleaning the area. The exhaust will surely be dirty, we agree. But when you are using epoxy, it is necessary to ensure that the adhesiveness works efficiently. When there is debris or dirt added to the exhaust, the adhesive won’t work that well.

So, it is better you get a brush for cleaning the space. Here, a hard brush is required for your job. Once you are done with the cleaning, get your hands on sandpaper and start rubbing the area. This will make the exhaust area smooth enough for the epoxy to sit with a better grip.

Step 3: Once again, clean

You might think that you have already cleaned the exhaust and you are ready to apply the epoxy. But there is more cleaning required! Yes, in this step, you have to clean the area with acetone. If you add epoxy and your adhesive does not work properly, the whole process will be of no use.

So, whenever it comes to increasing the adhesiveness of epoxy, you have to go through acetone and clean the exhaust. If you do not have acetone, a nail polish remover will do the job. However, never pour the whole bottle of acetone on the exhaust. Certify that you are using it only a tiny amount.

Step 4: Add the Adhesive

Now you have done all the cleaning and sanding processes and you are free for adding adhesive to the leak on your vehicle’s exhaust. It i time for mixing the adhesive. Some people mix the adhesive beforehand. We do not recommend that because, throughout the previous steps, your adhesive would have dried!

So, after you are done with all of the previous processes, you have to mix the adhesive. After mixing, start applying the glue to the leaks. Wait for about 4-5 minutes to ensure that the glue has dried. Once it is dried, you are done!

Using Repair Tape

You can fix all the holes and leaks below 5 mm with the adhesive we have mentioned above but how will you repair the leaks that are bigger than that? In this case, the best way to fix the exhaust leak without welding is the exhaust repair tape. As the name says, it will repair every leak you need!

  • First of all, search for the leaks that are larger than 5 mm. You can mark the leaks if you have a chance to forget where they are. Otherwise, just keep the points in your mind.
  • Now, just like we have done before, we will clean the area. First, get a hard brush and take off all the dirt and debris from the exhaust. Don’t forget to sand it. However, sanding is a complete person choice. Do if only if you want to.
  • After cleaning it with a brush, it is time for you to add acetone. Get a little bit of acetone and start rubbing it on the exhaust. It will be clean and glossy in a short while.
  • As you are done with the acetone cleaning, now, you have to get your hands on the repair tape and then fix the holes! Go through the leak and wrap it up with the repair tape. Go around the surface to make sure the leak is covered. We recommend you covering up the area several times so that there is no chance of leaking anymore.
  • The tape will take some time to dry. Let it sit there for a while. As you have covered the entire area, make sure you let it rest for a good amount of time before you apply anything else to the exhaust of your vehicle.

Using Patch

So far, we were trying to deal with the smaller leaks of 5 mm or close. It was easy to deal with the glue and the tape. But whenever it comes to the larger leaks, trust us; it is quite impossible for you to cover it up.

Yes, welding is one of the best methods of fixing the exhaust leakage but as we are unable to use that method, we will talk about the patch here! When your vehicle hits on the speed breakers or goes through serious jumps, there is a chance of larger leaks or damage. All you need is a good amount of p0atch of a tin can and then try to cover the pipe up!

  • For fixing the exhaust leak with the welding, first of all, you have to search for the leaks and then start cleaning it. The cleaning process can be done with the help of a hard brush. Remove the dirt and debris first.
  • Also, cleaning it with acetone will help the patch attach more perfectly. Add only a bit of acetone for the cleaning process. Now, you can sand the area for a better outcome.
  • As you are done with the leak searching and cleaning steps, you have to start by adding epoxy on the exhaust surface. Point out the leaks of your exhaust and then apply this adhesive there. Along with the exhaust surface, get some adhesive on the tin can patch too!
  • Now, get the patch on your hand and add the patch to the leaking area of the exhaust. For the adhesive, it will get attached easily. Clamps are great for adding the tin can patch too. However, if you apply adhesive, you have to wait for it to dry.

Wrap Up

All the three methods mentioned above are incredible for fixing the exhaust leak of your vehicle. Yes, we agree that things would have been better if you got your hands on the welding or power tools method. But, for quick fixes, these procedures are the best!

If the leak is larger and your exhaust is not working properly, make sure you do not repeat these processes. Instead, we recommend you to go for welding or a professional who can help you with it!
