Use Of Room Temperature Vulcanizing (Rtv) And Anaerobic Sealer - Chevrolet 5.7L Corvette 2004 Shop Manual

USE OF ROOM TEMPERATURE VULCANIZING (RTV) AND ANAEROBIC SEALER

Pipe Joint Compound
IMPORTANT: 3 types of sealer are commonly used in engines. These are room temperature
vulcanizing (RTV) sealer, anaerobic gasket eliminator sealer, and pipe joint
compound. The correct sealer and amount must be used in the proper location
to prevent oil leaks. DO NOT interchange the 3 types of sealers. Use only the
specific sealer or the equivalent as recommended in the service procedure.
Pipe joint compound is a pliable sealer that does not completely harden. This type sealer is used where 2
non-rigid parts, such as the oil pan and the engine block, are assembled together.
Do not use pipe joint compound in areas where extreme temperatures are expected. These areas include
exhaust manifold, head gasket, or other surfaces where 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 the pipe joint compound to a clean surface. Use a bead size or quantity as specified in the
procedure. Run the bead to the inside of any bolt holes.
Apply a continuous bead of pipe joint compound to one sealing surface. Sealing surfaces to be resealed
must be clean and dry.
Tighten the bolts to specifications. Do not overtighten.
RTV Sealer
RTV sealant hardens when exposed to air. This type sealer is used where 2 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.
