  3. Clean the cylinder head cover sealing surface at the front cover/cylinder head T-joints (1) with isopropyl alcohol in preparation for sealant application.
    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.

  4. Apply a 2 to 3 mm wide bead of Mopar® Threebond Engine RTV Sealant to the cylinder head cover sealing surface at the front cover/cylinder head T-joints (1).
