A one-component room-temperature vulcanizing (RTV) sealant. A high viscosity product that cures when exposed to air. The cured material has superior adhesion and elongation properties and is very resistant to engine oils and coolants. It is also oxygen sensor safe and will not corrode metal surfaces. This is the original production sealant used in GM engine plants. The sealant is compatible with all synthetic, synthetic blend, and minerals oils as well as coolant including DEX-COOL. The assembly may be filled with oil or coolant immediately after applying the sealant and torqueing the bolts. The maximum working time of this sealant is 20 minutes. The sealant will fully cure in 24 hours. Recommended for all engine applications.
