- Follow all safety recommendations and directions that are on the container.
To remove the sealant or the gasket material, refer to Replacing Engine Gaskets .
- Apply RTV sealant 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 the RTV sealant is still wet, within 3 minutes. Do not wait for the RTV sealant to skin over.
- Tighten bolts to specifications. Do not overtighten.
