How do you replace a 1999 Chevrolet Cavalier head gasket?

To replace the head gasket on a 1999 Chevrolet Cavalier, start by disconnecting the battery and draining the coolant. Remove the intake and exhaust manifolds, along with any components blocking access to the cylinder head, such as the alternator and Power Steering pump.
