USE OF ROOM TEMPERATURE VULCANIZING (RTV) AND ANAEROBIC SEALER
Sealant Types
Important: The correct sealant and amount of sealant must be used in the proper location in order to prevent oil
leaks, coolant leaks, or the loosening of the fasteners. DO NOT interchange the sealants. Use only the sealant, or
equivalent, as specifi ed in the service procedure.
The following 2 major types of sealant are commonly used in engines:
• Aerobic room temperature vulcanizing (RTV) sealant
• Anaerobic sealant, which include the following:
- Gasket eliminator
- Pipe
- Threadlock
RTV Sealant
Aerobic type RTV sealant cures when exposed to air. This type of sealant is used where 2 components, such as the
intake manifold and the engine block, are assembled together.
Use the following information when using RTV sealant:
• Do not use RTV sealant in areas where extreme temperatures are expected. These areas include:
- The exhaust manifold
- The head gasket
- Any other surfaces where a different type of sealant is specifi ed in the service procedure
• Always follow all safety recommendations and the directions that are on the RTV sealant container.
• Use a plastic or wood scraper in order to remove all RTV sealant from the plastic and aluminum components.
