OIL PAN
Removal (Dakota 2WD & Durango 2WD)
1) Disconnect negative battery cable. Remove oil dipstick and
distributor cap. Raise and support vehicle. Drain engine oil.
2) Remove exhaust pipe. Remove side engine mount bolts.
Slightly raise engine. When engine is at adequate height, install
bolts in side engine mount-to-frame bracket holes to support engine.
3) Lower engine, and allow it to rest on bolts installed in
side engine mounts. Remove oil pan bolts, oil pan and gaskets.
Installation
1) To install, reverse removal procedure. Before installing
oil pan, apply RTV sealant where front cover contacts cylinder block,
where oil pan side gaskets meet end seals, and where end seals contact
cylinder block. See Fig. 14.
2) To facilitate oil pan installation, fabricate 4 alignment
dowels from 1 1/2" x 5/16" bolts. See Fig. 15. Tighten bolts to
specification. See TORQUE SPECIFICATIONS table. To install remaining
