RTV sealant hardens when exposed to air. This type sealer is used where two non-rigid parts, such as the intake manifold and the engine block, are assembled together.
Do not use RTV sealant in areas where extreme temperatures are expected. These areas include: exhaust manifold, head gasket, or other surfaces where a gasket eliminator is specified.
Follow all safety recommendations and directions that are on the container.
To remove the sealant or the gasket material, refer to Replacing Engine Gaskets .

NOTE: Refer to Sealant Notice in Cautions and Notices.

Apply RTV to a clean surface. Use a bead size as specified in the procedure. Run the bead to the inside of any bolt holes.
Assemble components while RTV is still wet, within 3 minutes. Do not wait for RTV to skin over.
Tighten bolts to specifications. Do not overtighten.
