2. Remove upper exhaust manifold heat shield. Remove exhaust manifold brace. Remove lower exhaust manifold heat shield. Loosen exhaust manifold to exhaust manifold spring loaded nuts. Remove radiator outlet
pipe to water pump cover bolts. Disconnect exhaust pipe from manifold.
3. Pull down on exhaust pipe to disconnect if from exhaust manifold bolts. See EXHAUST MANIFOLD . Disconnect outlet pipe from oil pan and transaxle. If equipped with manual transaxle, remove exhaust
