You've probably already heard of the exhaust manifold, but that doesn't necessarily mean you understand what it's for. In fact, this system is very important in the operation of your car. It connects the cylinder head to your engine's exhaust port. This allows the hot exhaust to pass through the pipe instead of seeping into the air and the vehicle itself. The manifold can be made of cast iron or a set of pipes, it all depends on the car you drive.

Since this manifold is always cooling and heating up as the gases pass through it, this means that the pipe is regularly contracting and expanding. This can be quite difficult for him and even lead to cracks and breaks. As soon as this happens, vapors will begin to seep out. These leaks are very dangerous to your health as you will be inhaling gases instead. In addition, it starts to reduce the performance of your engine.

In the case of the exhaust manifold, the question is not whether it will fail over time, but when it will fail. It's a good idea to have your exhaust manifold checked by a certified mechanic from time to time, just so you can spot any cracks as early as possible. In the meantime, here are some signs that may indicate that your exhaust manifold needs to be replaced.

• Since your engine will not be running efficiently, the Check Engine Light will most likely come on. You will need a mechanic to read and then clear the computer codes.

• Your engine may not run as well as it used to, as a bad exhaust manifold greatly affects engine performance.

• There are sounds and smells that can also serve as clues. The engine may start making loud noises that you can hear even while driving. If the exhaust manifold is leaking, you will likely smell the odor coming from the engine bay. It will be the smell of plastic parts near the exhaust manifold that are now melting due to the heat escaping.

The exhaust manifold connects the cylinder head to the engine exhaust port. As soon as this part fails, you will notice that different things start to happen to your engine and the overall performance of the car. If you are experiencing any of the above symptoms and suspect that your exhaust manifold needs to be replaced, get a diagnosis or have an exhaust manifold replacement service from a professional mechanic.
