An intake manifold operates to distribute the air and fuel combination if by the engine's carburettor to Everyone of the engine's cylinders and again to supply a course for the engine's antifreeze to flow nailed down to gelid the engine. Over fluids are constantly passing though the intake manifold, the manifold uses four gaskets to prevent leaks. Over age, intake manifold gaskets corrode, resulting in leaks. Although fluid can leak onto the exterior of the engine, leaky intake manifold gaskets typically arrangement in the mixing of fluid within the engine. Thankfully, replacing the intake manifold gaskets on a Chevy Malibu is a relatively straightforward action.
Instructions
1. Remove the air cleaner meeting from the top of the carburettor by anterior twisting the unmarried wing devotee located at the top of the air cleaner in a counterclockwise succession, then by lifting the air cleaner meeting off of the carburettor.
To remove the fuel edge, aboriginal loosen the screw on the hose clamp with a flathead screwdriver, then pull the fuel limit outside from the carburettor. Any vacuum lines attached to the carburettor, such as for a vacuum advance distributor, can be simply pulled off of the carburettor. Remove the throttle linkage from the carburettor by removing the unmarried screw that attaches the linkage to the carburettor, then by pulling the linkage absent.2. Disconnect the fuel edge and the throttle linkage from the carburettor, followed by any vacuum lines attached to the carburettor. The fuel path is held into assign with a unmarried hose clamp.
3. Remove the carburettor from the intake manifold by removing Everyone of the four nuts that mastery the carburettor in lay with a wrench, then by lifting the carburettor elsewhere from the engine. There is one peanut located at Everyone corner of the model of the carburettor.
4. Remove the distributor and the upper radiator hose from the intake manifold. The distributor is located at the rear of the intake manifold and is held in dwelling with a unmarried bolt that must be removed with a wrench. The upper radiator hose attaches to the front of the intake manifold and can be removed by loosening the screw on the hose's clamp with a screwdriver, then pulling the hose out from the intake manifold.
5. Remove Everyone of the intake manifold's bolts with a wrench, then lift the intake manifold off of the engine. Disinfected the four surfaces which surround the backside of the intake manifold, also as the surfaces on the engine, with a gasket scraper to lock on that these surfaces are free of charge from debris.
6. Coat one side of Everyone of the four intake manifold gaskets with gasket sealer. Deposit both of the two longer gaskets against the mating surface on the intake manifold. The side of Everyone gasket coated with gasket sealer must face the intake manifold. Place one shorter gasket against the manifold's mating surface on the front of the engine, and the other shorter gasket against the manifold's mating surface on the back of the engine. Coat the exposed sides of all four gaskets with gasket sealer, then lower the intake manifold onto the engine. Insert each of the manifold's bolts through the manifold and into the engine, then tighten each bolt with a wrench.
7. Insert the distributor into the back of the intake manifold and secure the distributor into place with the distributor's single bolt. Slide the upper radiator hose onto the front of the intake manifold, then tighten the hose clamp to secure the hose in place.
8. Lower the carburetor onto the intake manifold, then install and tighten each of the four carburetor mounting nuts. Connect the fuel line and any vacuum lines to the carburetor, followed by the throttle linkage.
9. Install the air cleaner assembly onto the top of the carburetor, then tighten the wing nut located on top of the assembly to complete the replacement process.
