LP Engine G430 (3.0L)
General Information
4. Assembling components:
• When assembling components, use only the
sealant specified or equivalent in the service
procedure.
• Sealing surfaces should be clean and free of
debris or oil.
• Specific components such as crankshaft oil seals
or valve stem oil seals may require lubrication
during assembly.
• Components requiring lubrication will be identified
in the service procedure.
• When applying sealant to a component, apply the
amount specified in the service procedure.
• Do not allow the sealant to enter into any blind
threaded holes, as it may prevent the bolt from
clamping properly or cause component damage
when tightened.
• Tighten bolts to specifications. Do not overtighten.
Use of RTV and Anaerobic Sealer
IMPORTANT: Three types of sealer are commonly
used in engines. These are 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
three types of sealers. Use only the specific sealer or
the equivalent as recommended in the service
procedure.
Pipe Joint Compound
• Pipe joint compound is a pliable sealer that does not
completely harden. This type sealer is used where
two nonrigid 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 manifolds, 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.
• 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
•
Room Temperature Vulcanizing (RTV) sealant
hardens when exposed to air. This type sealer is
used where two nonrigid parts (such as the oil pan
and the engine block) are assembled together.
• Do not use RTV sealant in areas where extreme
temperatures are expected. These areas include:
exhaust manifolds, 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.
• Apply RTV to a clean surface. Use a bead size as
specified in the service procedure. Run the bead to
the inside of any bolt holes. Do not allow the sealer
to enter any blind threaded holes, as it may prevent
the bolt from clamping properly or cause damage
when the bolt is tightened.
• Assemble components while RTV is still wet (within
three minutes) . Do not wait for RTV to skin over.
•
Tighten the bolts to specifications. Do not
overtighten.
Anaerobic Sealer
• Anaerobic gasket eliminator hardens in the absence
of air. This type sealer is used where two rigid parts
(such as castings) are assembled and no sealer or
gasket is readily noticeable, the parts were probably
assembled using a gasket eliminator.
• 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 a continuous bead of gasket eliminator to one
flange. Surfaces to be resealed must be clean and
dry.
• Spread the sealer evenly with your finger to get a
uniform coating on the sealing surface. Do not allow
the sealer to enter any blind threaded holes, as it
may prevent the bolt from clamping properly or
cause damage when the bolt is tightened.
•
Tighten the bolts to specifications. Do not
overtighten.
• After properly tightening the fasteners, remove the
excess sealer from the outside of the joint.
