Description
The ACDelco 12378521 RTV Engine Sealant is the sealant used in GM engine plants. Reseal your engine components with the same high-quality sealer used in the GM Production Line. ACDelco RTV Engine Sealant is a one-component, room-temperature vulcanizing (RTV) sealant. It is a high viscosity product that cures when exposed to air.
