NOTE: Ensure components being sealed with room temperature vulcanizing (RTV) sealant are assembled within 20 minutes. Components assembled after the RTV sealant has skinned-over, approximately 20 minutes, will not seal properly.

Ensure the RTV sealant GM P/N 12378521 (Canadian P/N 88901148) or equivalent bead is higher than the oil pan sealing surface (1) by 3 mm (0.118 in).
