Chevrolet Sonic Repair Manual: Replacing Engine Gaskets

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.
