How to remove and install an exhaust manifold on 2.2L four cylinder engine?

Remove the cable from the negative battery terminal. Remove the air cleaner assembly and duct. Remove the oxygen sensor from the manifold. Raise the vehicle and securely support it on jackstands. Disconnect the exhaust pipe from the exhaust manifold. You may need to apply penetrating oil to the fastener threads as they are usually corroded. On air-conditioned models, remove the air conditioning compressor rear mount, and remove the nut and the oil filler tube without disconnecting the lines. Remove the nut on the oil filler tube assembly. Remove the exhaust manifold nuts and separate the exhaust manifold from the engine. Remove the exhaust manifold gasket. Before installing the manifold, clean the gasket mating surfaces on the cylinder head and manifold. Remove all old gasket material and carbon deposits. Check the bolt threads for damage. Place a new exhaust manifold gasket in position on the cylinder head, then place the manifold in position and tighten the mounting nuts. Install the remaining components in the reverse order of removal. Start the engine and check for exhaust leaks between the manifold and cylinder head, and between the manifold and exhaust pipe.

How to remove the exhaust manifold on 4.3L V6 engine?

To take off the exhaust manifold, first disconnect the negative battery cable and lift the vehicle on jackstands. Apply penetrating oil to the exhaust pipe-to-manifold studs and nuts then remove the nuts which hold the exhaust pipe(s) to the manifold(s). On TBI models, this will involve removing the air cleaner assembly and also heat stove pipe on right side manifold. Disconnecting spark plug wires and brackets as well as unbolt air conditioning compressor with its bracket then leave only one screw that you loosened for last. Remove oil dipstick and tube bracket. Removing rear brace from alternator (unbolt), spark plug wires, EGR pipe (1996 and later models) etc. Take out power steering pump pulley after removing rear power steering bracket by removing mounting bolts. Bend lock tabs back, then remove mounting bolts followed by separation of exhaust from cylinder head. Clean both surfaces where manifold mates with cylinder head. Place it over cylinder head onto which it is mounted with installing three fastening screws in a sequence which divides them into three equal parts.

GMC Sonoma Exhaust Manifold

Exhaust Manifold operating in GMC Sonama models plays a critical role of channeling hot fumes produced in the engine back into the exhaust system; through the catalytic converter and the muffling system. Sitting in variable locations on the engine block the manifold aims to stop intake reversion which slows the flow of air to the engine. GMC Sonoma exhaust manifolds can further be of cast iron or stainless steel and headers commonly exist in parts to improve flow resistance of the engine. Headers enhance exhaust gas velocity so as to enhance the performance of the vehicle. The material put into the exhaust manifold and the design as well that has been put into the engine can change the efficiency and durability and some changes like coatings with ceramics can also change the life expectancy. It is therefore crucial that general and regular maintenance and replacement of a defective exhaust manifold is docketed so as to enhance the efficacy of the car and safety.

Each OEM GMC Sonoma Exhaust Manifold we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
