Chevrolet Sonic Repair Manual: Replacing Engine Gaskets
- Gasket Reuse and Applying Sealants
-
- Do not reuse any gasket unless specified.
- Gaskets that can be reused will be identified in the service procedure.
- Do not apply sealant to any gasket or sealing surface unless called
out in the service information.
- Separating Components
-
- Use a rubber mallet to separate components.
- Bump the part sideways to loosen the components.
- Bumping should be done at bends or reinforced areas to prevent distortion
of parts.
- Cleaning Gasket Surfaces
-
- Remove all gasket and sealing material from the part using a scraping
tool.
- Care must be used to avoid gouging or scraping the sealing surfaces.
- Do not use any other method or technique to remove sealant or gasket
material from a part.
- Do not use abrasive pads, sand paper, or power tools to clean the gasket
surfaces.
- These methods of cleaning can cause damage to the component sealing
surfaces.
- Abrasive pads also produce a fine grit that the oil filter cannot
remove from the oil.
- This grit is abrasive and has been known to cause internal engine
damage.
- 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.
