Notice: Apply the proper amount of the sealant when assembling this component. Excessive use of the sealant can prohibit the component from
sealing properly. A component that is not sealed properly can leak leading to extensive engine damage.

intake manifold gasket at each end.
Important: The lower intake manifold gasket must be installed while the adhesive is still wet to the touch.
2. Install the lower intake manifold gasket onto the cylinder head.
3. Use the gasket locator pins in order to properly seat the lower intake manifold gasket on the cylinder head.
