This procedure applies to both cylinder heads, with removal of engine and transaxle assembly suggested. Begin by removing the camshafts, camshaft housings, and exhaust manifolds. For the left cylinder head, remove the front bolts and all cylinder head bolts in reverse order for head removal. Discard the old gasket. During installation, clean the cylinder head and block mating surfaces. Prevent oil presence for proper gasket sealing. Inspect surfaces for damage and clean the cylinder head bolt holes. Position the gasket correctly, apply oil to new bolts and install them, tightening gradually in the specified sequence. Retighten each bolt 90 degrees twice. If both were removed, install the other. Continue with the camshafts, oil control valve, filter, and sensor installation. Finish by reversing removal steps, refilling oil and coolant, starting the engine, and checking for leaks.

The remainder of the installation process is the reverse of removal. You should wait at least four hours before adding oil and coolant and starting the engine.
