Application & Curing
The ACDelco 10-2010 is a room-temperature vulcanizing sealant, commonly referred to as RTV.
Once exposed to moisture in the surrounding air, the sealant begins the curing process. Because curing begins after application, components should be positioned and assembled promptly according to the applicable service procedure.
Improper application can contribute to leaks or other service issues, so always use the correct amount of sealant and follow the vehicle manufacturer\'s repair instructions.
Signs of Improper RTV Application
Improper RTV silicone use may result in:
- Leaks along the application seam
- Incomplete sealing between mating surfaces
- Improperly positioned components
- Contamination of sealing surfaces
- Excess or insufficient sealant in the repaired area
Parts should always be thoroughly cleaned before applying silicone sealant.
