NOTE:

WK oil pan shown in illustration, JK oil pan similar.

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:

Clean the upper and lower oil pans, timing chain cover, rear seal retainer and engine block mating surfaces thoroughly with isopropyl alcohol in preparation for sealant application. All surfaces that seal with RTV must be oil and contamination free to ensure proper adhesion of the RTV to the mating surface to prevent leaks.

CAUTION:

Following the application of Mopar® Threebond Engine RTV Sealant to the gasket surfaces, the components must be assembled within 20 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.

    • Oil pan to engine block flange (1)
    • Two timing cover to engine block T-joints (2)
