To pull the 3.7L engine out, the vehicle has to be lifted, and supported properly on two jackstands. Remove the engine oil, of which an example is shown in Fig. 7-3, clean the drain plug, and remove the oil filter. Following this, refer to that you have to set up the lower engine splash shield, and then remove the crossmember brace together with the mounting bolts and the strut tower cross brace. Dash out the battery and the battery tray, the oil dip stick, the ground strap, and harness retainers throughout the back of the engine. Loosen the four bolts of oil pan-to-timing chain cover and the two nuts at the 
Engine Mount. Remove radiator upper cover and support brackets and support the engine from above by fixing a fixture to the cylinder head with legs set correctly so as not cause body damage. Rmve the transnssion-to-oil pan bolts, disconnect the connectors from the power electronic assist steering and unbolt the steering shaft from steering gear. Place to floor jacks under the subframe, take off the subframe bolts, and drop the subframe. Remove the upper transmission-to-engine bolts and commence to turn them clockwise, while using a screwdriver to prise the engine and the transmission apart at the bell housing. The oil pan fasteners have to be detached, along with the oil pan, and this is best done with notches to help you push them out. Scrub the oil pan in order and get ready for it to be fitted by applying RTV sealant at certain points after and then fit the oil pan while tightening the bolts in a certain manner. The backward involves refastening of the fasteners with tightens nuts to standard torque values, replacing of self-locking nuts, refilling of the engine oil and the addition of new oil filter before restarting the engine in order to detect leaks. In the 4.0L engine the oil pan assembly has the lower sheet metal pan as well as the upper aluminum one. To remove the oil pan, the engine must be pulled out and the lower oil pan fasteners and the 
Oil Pump screen cover must be removed. Remove the reinforcement section by the needed bolts while being cautious not to apply pressure on the gasket surfaces. For installation, first clean all the surface then apply RTV sealant if requires and then place new gaskets and put the reinforcement section of the drive and ensure that there must be proper clearance to avoid any kind of damage. Lastly, all the bolts should again be tightened up to the required torque and then the oil pump pickup tube and the oil pan should also be fitted efficiently on to the places that they belong to.
