Chevrolet Sonic Repair Manual / Powertrain / Engine / General / 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.
