Chevrolet Sonic Repair Manual: Case Porosity Repair
Some external leaks are caused by case porosity in non-pressurized areas.
- Thoroughly clean the area to be repaired with a cleaning solvent. Air dry the area.
- Using instructions from the manufacturer, mix a sufficient amount of an epoxy to make the repair.
- Apply the epoxy. A clean, dry soldering acid brush can be used to clean the area and also to apply the epoxy cement. Make certain that the area to be repaired is fully covered.
- Allow the epoxy cement to cure for three hours before assembling the components.
- Repeat the fluid leak diagnosis procedures.
Warning:
Epoxy adhesive may cause skin irritations and eye damage. Read and follow all information on the container label as provided by the manufacturer.
