To remove the exhaust manifold, you will not require any tool but to turn off your car's radio, make sure you have the code for triggering the car radio in case it has an anti-theft gadget. Subsequently, lift up the front of the car and provide prop up support for this area by using hydraulic jack stands next, un-bolt the exhaust joint by using a wrench and after that, it will be wise to apply some penetrating lubricant. Unbolt the heat shield and put a penetrating oil to the bolts that hold the exhaust manifold in place. Subsequently, remove the exhaust manifold nuts and disconnect the manifold from the
Cylinder Head and don't forget the bolts of the lower brace near the flange. To install do not reuse gasket and to scrap off the dirt on the manifold and head use a scraper and a rag which has been dipped in laquer thinner or acetone. Place the new exhaust manifold onto the cylinder head and then fit the nuts and tighten them starting with the nut at the center in a clockwise and anti-clockwise pattern to the required force. At last, switch on the engine and look for some of the common exhaust leaks such as those between the manifold and the cylinder head as well as the manifold and the exhaust pipe.
