  1. Clean and gasket sealing surfaces. Refer to ENGINE GASKET SURFACE PREPARATION .
    CAUTION:

    Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar® Threebond Engine RTV Sealant may result in engine fluid leakage.

    CAUTION:

    Following the application of Mopar® Threebond Engine RTV Sealant to the gasket surfaces, the components must be assembled within 10 minutes and the attaching fasteners must be tightened to specification within 45 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.

    NOTE:

    Sealing surfaces must be free of a gasket material and oil residue. Clean the oil pan sealing surfaces with isopropyl alcohol in preparation for sealant application.

  2. Apply a 3 mm wide bead of Mopar® Threebond Engine RTV Sealant to the lower oil pan as shown in the illustration (1).
