Chevrolet Sonic Repair Manual: Service Prior to Assembly

Chevrolet Sonic Repair Manual / Powertrain / Engine / General / Service Prior to Assembly

The importance of cleanliness during assembly cannot be overstated. Dirt or debris will cause engine damage. An automobile engine is a combination of many machined, honed, polished and lapped surfaces with minor tolerances. When any internal engine parts are serviced, care and cleanliness are important. A liberal coating of engine oil should be applied to friction areas during assembly in order to protect and lubricate the surfaces on initial operation. Throughout this section, it should be understood that proper cleaning and protection of machined surfaces and friction areas are part of the repair procedure. This is considered standard shop practice even if not specifically stated.

Use the proper tools to measure the components when checking for excessive wear. Components not within the manufacturer's specification must be repaired or replaced.

Lubricate all moving parts with engine oil or a specified assembly lubricant. This will provide lubrication for initial start up.

When the components are reinstalled into an engine, return the components to their original location, position, and direction.
