Before removing the oil pan, first, disconnect the cable of the negative terminal of the battery. Apply your parking brake and lay rear wheels chocks, lift the front of the car and put it on jack stands securely. If installed, unbolt the engine splash shield, drain engine oil and take off oil-filter along with the dipstick. Subsequently, take out all obstructions and unscrew the lower oil pan-the upper part of which is made of cast steel while the lower part is a stamped steel part. Take out all the upper bolts and then disengage the oil pan; one must remember that different bolts that are used bear distinct sizes and it is wise not to apply undesirable force when removing these bolts so as to avoid damaging the surface of mating. During installation, scrape the block and oil pan where the sealant is to be applied free of old material, clean the mating surfaces, and also clean the threaded bolt holes. Examine the condition of the oil pan flange for bulging and spread a 3/16 inch wide line of RTV sealant on the oil pan flange contact surface. Place the oil pan onto the engine block and put all bolts loosely in place, then tight it from center towards the periphery and increase it to the recommended torque. Place the lower oil pan and secure it with the bolts through multiple passes with a torque of twenty-five foot-pounds, and finish off by taking the car for a spin to check for oil pressure and signs of leakage.
