How to Fix an Exhaust Manifold Leak?

You’re driving and all of a sudden you hear a loud hissing noise from your exhaust, it’s an indication of leaking exhaust. Now, if your car is leaking exhaust, it’s important to fix the problem as soon as possible. 

An exhaust manifold leak can be dangerous because it can allow deadly carbon monoxide gases to enter the cabin of your car. Luckily, fixing an exhaust manifold leak is usually a relatively easy and inexpensive repair.

How to Fix an Exhaust Manifold Leak

Step 1: Determine the Cause of the Leak

The first step is to determine where the leak is coming from. Because based on the area of leaking, you can confirm the cause of the leak.

This can be done by taking a look at your exhaust system and identifying any areas that may be damaged. The best way to do this is to have someone start the car while you listen for the leak. It’s also a good idea to look for any signs of exhaust leaking from the manifold.

If you don’t know how to do this, ask a mechanic or a friend who is familiar with car mechanics.

Step 2: Fix Any Damaged Areas

Once you have determined the cause of the leak, you need to fix any damaged areas. This may include fixing welds, replacing gaskets, and repairing pipes.

Step 3: Secure the Leak Area

After you have repaired any damaged areas, it is important to secure them with bolts or screws. Make sure that the area is properly sealed so that no more water or gas can escape.

Step 4: Check for Leaks Again

Once you repaired and secured the leak area, carefully start and observe for a while if the leak stopped. Sometimes, though you fix and secure the leaking area, it may appear again after you run the car. In that case, you have to rework.

Step 5: Drive It!

After you successfully fix it, drive happily without any hesitation and overthinking.


That’s it! Your exhaust manifold leak is now fixed. If it happens again, just repeat these steps.
