Installing an exhaust manifold is not a very difficult or complicated job. An exhaust manifold is an important part of any vehicle. It routes all the exhaust gases safely away from the interior of the vehicle. You will need to install an exhaust manifold if the one on your vehicle is damaged or faulty. If you replace the gasket on your exhaust manifold you will need to know how to put the manifold back. This is a job that is worth knowing how to do, otherwise you will have to take it to a mechanic to get it done. Doing the job by yourself will save you some money.

Step 1 - Getting Started

Find a good place to work on your vehicle; you will need sufficient light and space. Try not to work in a cramped space that has no proper lighting.

Step 2 - Remove the Old Manifold

Remove the old exhaust manifold from the vehicle. You will need to remove the bolts that hold the manifold in place.

Step 3 - Clean the Surface

Use the putty knife to gently scrape away all the remains of the old gasket. You will need to make sure the surface is completely clean before installing the new manifold.

Step 4 - Cleaning Solution

Use a cleaning solution like alcohol or brake cleaner to clean the places that are a bit harder to clean. You will need the surface to be without any deposits.

Step 5 - Place the New Exhaust Manifold Gasket

Place the new manifold gasket on the mating surface, but do not use any gasket sealer. Make sure the new manifold gasket is correctly positioned before you begin placing the exhaust manifold.

Step 6 - Place the Manifold

Carefully position the manifold over the new gasket.

Step 7 - Insert Bolts

Place the first bolt through the manifold into the head and turn it slowly with your hand until it locks with the threads in the head. Do not tighten it yet. Insert the second bolt into the hole opposite to the first bolt. Turn the bolt with your hand until it locks with the threads. Again, do not tighten the bolt. Put all the remaining bolts in place and follow the same process of turning them with your hand until they lock with the thread.

Step 8 - Tighten the Bolts

Use the torque wrench for tightening the bolts on the manifold. It is important you follow the manufacturer's specifications while tightening the bolts. Don't tighten them more than what is recommended.

Step 9 - Finishing

Check that all the bolts are tightened according to recommended torque specification. That's all you need to do to install an exhaust manifold.
