To extract the engine, one first detaches oil dipstick tube and bracket, throttle body linkages and wires, vacuum hoses so as to allow for the lifting of the engine. To do this remove the fuel supply and return lines from the fuel rail, power steering pump and air conditioning compressor from their bracket. Remove the manual shift and kickdown linkage from the automatic transmission, also, unscrew the driveshaft of the transmission. For all models, remove the negative battery cable and for 5.0 L or 5.8 L engine with fuel injection, the upper intake manifold must be removed. Sump the engine oil and the cooling system, and then unbolt the radiator should the engine have to be lifted. Lift the car up using the jack and then apply the jack stands to support the car, then remove the engine front insulator to support bracket nuts and washers along with the nuts connected to the exhaust pipes and manifolds. Place a piece of thick wooden between the jack and the oil pan to lift the front part of the engine and make certain that all cables, wires and hoses are loose. On all engines except the 7.5L, lift the engine up only slightly to allow the oil pan to clear while on the 7.5L lift the engine up until the transmission bellhousing rest upon the floor pan. Insert wooden planks between the front support insulators and support brackets to retain the raise position and the lower the engine with the spacer blocks and withdraw the jack. Next, the oil pan attaching bolts to be removed before lowering the pan to the crossmember is next. For 5.0 and 5.8L engines, undo the oil pump inlet tube-to-oil pump retaining bolts and let the inlet tube sometimes fall downwards into the pan. For 7.5L engine: this one is easy; just pull out the whole pump out of the block and let it fall into the pan. Last, take off the oil pan from the car and strive to eliminate any gasket material from the surfaces of both the engine and the pan. apply RTV sealant when installing, use a thin layer of RTV sealant to both faces of the gasket(s) and it it into the pan. For 5.0 and 5.8L engines, remove and clean the oil pump pick-up tube and screen assembly, and for 7.5L engine, clean the inlet tube screen and fill the oil pump with oil before installing the same into the oil pan. Lower the oil pan into position, install the inlet tube and screen assembly with a new gasket and screw it to the oil pump and tighten the bolt. Fit the pump and pickup tube to the block for the 7.5L engine, secure the oil pan to the engine block and in addition tighten the retaining bolts sequentially. It is necessary to lift the engine with a jack, to remove the wooden spacers, to lower the engine, to install the engine mounts. To finish up with the installation, add coolant to the cooling system, add oil to the engine and finally join the negative terminal of the battery. Twist on the engine and search for leakage at the oil pan gasket flattened areas.
