How to Remove an Intake Manifold


Repairing your car may seem intimidating, but learning to do easy mechanic jobs will save you a lot of money and hassle. The intake manifold, usually a plastic piece with no moving parts, is responsible for providing airflow to your car's internal combustion engine [source: Juran]. With no airflow, the gasoline cannot be ignited and your car won't start. Follow the easy steps below to remove the intake manifold and have your car purring again.

  1. Remove the air filter and air filter container. Pay close attention during the removal process; you will have to reconnect all the parts when replacing the intake manifold.
  2. Open the hose clamp with a flathead screwdriver. Remove the carburetor's fuel line and any vacuum lines that are attached to the carburetor.
  3. Remove the links attached to the throttle by removing the screws with the screwdriver.
  4. Loosen the nuts holding together the carburetor and intake manifold. They're located on the four corners of the carburetor.
  5. Remove the distributor by loosening the connecting bolts with a wrench.
  6. Remove the upper radiator hose from the intake manifold by loosening the screws with your flathead screwdriver.
  7. Loosen the bolts fastening the intake manifold to the engine.
  8. Clean the surface of the engine.
  9. Prep the new intake manifold for installation by checking for any leaks from the gaskets and applying gasket sealant on both sides of each gasket.
  10. Fit the new intake manifold into place next to the engine block. Replace the bolts, screwing them in and securing the intake manifold to the engine.
  11. Reinstall the upper radiator hose, distributor, carburetor, links to the throttle, carburetor fuel line, vacuum lines and air filter [source: Morgan].
