1. Remove the setscrews (1) in the reverse numerical order to the Illustration 1. This will help to prevent any distortion of the exhaust manifold (2).

2. Remove the exhaust manifold gasket from the cylinder head and remove the exhaust manifold (2). Discard the exhaust manifold gasket.

Installation Procedure for the Three Cylinder Engine

Note: The improper installation of the exhaust manifold (2) can result in a cracked exhaust manifold. The setscrews (1) for the exhaust manifold must be tightened in the correct sequence and tightened to the correct torque.

1. Loosely install two suitable studs into the holes (5 and 6) as guides.

   Note: Do not use any sealant on the exhaust manifold gasket.

2. Position the new exhaust manifold gasket onto the studs in the cylinder head. Position the exhaust manifold (2) onto the studs. Install the setscrews (1) finger tight in order to secure the exhaust manifold to the cylinder head.

3. Remove the two studs and install the remaining setscrews (1). Ensure that the setscrews (1) are tightened in the sequence that is shown in Illustration 2. Tighten the setscrews evenly to a torque of 33 N·m (24 lb ft).
