The oil pan comprises an upper alloy half and a lower steel oil pan; however, the following procedure relates to the lower oil pan. First, engage the handbrake, and then follow it up by raising the front of the car off the ground and placing it on jack stands. Squeeze out the engine oil, clean the engine oil pan drain plug and reinstall it with a new gasket and tighten it to recommended torque. In case the engine is close to the particular service interval is reached, it will also be useful to take out the oil filtration device and put in a brand new one. Subsequently, gradually loosen and finally untighten all the retaining bolts of the steel oil pan. The lower steel oil pan is bolted and sealed with a liquid metal gasket to the upper alloy oil pan casing; This may need the use of a spatula or thin knife to ease the oil pan out from the casing without straining and bending the sealing surfaces. Ensure that any further coming out of oil is caught in a container while the oil pan is being withdrawn. In refitting, clean the mating surface of sealant on both the upper alloy part and steel oil pan, also wipe the inside clean with a piece of rag. The mating surfaces should be clean and dry before putting down a continuous bead of a suitable sealant around the inner periphery of the bolt holes of the oil pan. Locate the oil pan properly and reinstall the retaining bolts level with each other and gradually tight it to the required torque sequence. Finally, after reassembly, add new oil and switch on the engine to allow it to warm up to normal operating conditions check for any dripping from the oil pan region.
