Nissan 31390-1XF00 Pan Assy-Oil

The undertaking entails the stripping off of two pans; the lower steel oil pan and the upper aluminum oil pan with the notion that if only the lower pan is being stripped off, a number of steps may not be taken since the pan is easily accessible. On 2.0L engines, the upper oil pan is best reached by separating the engine and transaxle; the oil pump is located with the upper pan, and therefore, cannot be removed individually. Start off by first removing the negative terminal of the battery, then the lugs that holding the right front wheel, placing and topping the car on jackstands safely and finally removing the right front wheel. Sump the engine oil, remove the front portion of the exhaust pipe and the drive belt. On smaller 2.5L engines, the right side of the car, take off the driveaxle bearing bracket and air conditioning compressor; however, leave the lines connected. For the vehicle of 2.0 L power unit, the timing chain cover, timing chain, and oil pump drive chain and sprocket have to be dismantled. Next, remove the flywheel/driveplate. This is made up of a two-part system, consisting of a steel pan fixed to an aluminum piece that is bolted onto the engine; to dismantle the oil pan, undo the oil pan bolts in a backward sequence of how they were tightened and then you can separate the steel part using a thin putty knife more so do not pry the part using a screwdriver. While on 2.5L engines, there are fasteners that holds the oil pump screen and on 2.0L engines, the oil pump an the screen are fixed there permanently. First loosen the bolts that fixed the aluminum section to the engine block, and trim the sealant around the aluminum section with putty knife and then pry it down at the transaxle end. For installation, use a scraper to remove old gasket material and sealant on the flanks of the metallic surfaces, clean the areas that the bolts are to screw into, and make sure they are clean. Make sure the steel pan flange has not distorted and needs to be repaired if it has. Spread a 3/16-inch wide strip of RTV sealant around the section of aluminum, and replace the O-rings if there are Some, place the section of aluminum on the engine block, then put the bolts in and tighten them in a star pattern to the recommended torque. Cookie all the round RO sealant in the steel pan perimeter and set the pan in the RV within 15 minutes by successively applying torque to the bolts. Re-install the removed parts by substituting the old oil filter with the new one, wait for at least half an hour before adding oil to let the RTV set, reconnect the battery and perform any re-learn operations.

Much attention is paid to the procedure of the lower steel oil pan and the upper aluminum oil pan removal, whereas it is stated that if the only with lower pan is carried out, many steps can be omitted due to its accessibility. First, remove the nutrients of negative battery terminal, then loosen the lug nuts of the right front wheel and jack up the vehicle, and at last, take out the right front wheel off from the car. Suck out the engine oil and remove the engine oil filter next, and remove the engine oil dipstick tube this time and fit a new O-ring ring on the tube. Take out next the front part of the exhaust pipe, the drivebelt, as well as the right side driveaxle bearing bracket; next, the air conditioning compressor with its lines remaining connected. As the following step, you have to take out the lower torque rod and the transfer case for the AWD car models, after that you have to unbolt the stabilizer bar link and unbolt pr front subframe. The oil pan as a two-part construction: a steel pan, which is welded to an aluminum part which is sculpture to the block head. Uncrown the bolts that hold the oil pan starting from the reverse sequence in which you tightened them and use a thin putty knife to detach the steel pan but ensure that the sealing surface is not damaged. Label all the bolts for re-assembly next, then unscrew and pull out the oil pump screen and its supporting bolts. Unfasten the bolts that hold the aluminum section to the engine block turning the bolts in the reverse order of tightening and proceed to cut the sealant on the aluminum section before finally prying it down. Regarding installation, it is advisable to cut and remove all the old gasket material and sealant on the block and the oil pan without scratching the surfaces. Ensure the steel pan flange is not distorted and place a strip of RTV sealant on the perimeter of the aluminum section and place in within 15 minutes. If it's required new shorter O-rings to fit them, place the aluminum section on the engine block, and fasten all bolts in a sequence in correct torque limit. Where required, use RTV sealant on the steel pan, then place the steel pan in the location and refraining from loosening the bolts tighten them in concentric pattern to the indicated torque. To complete the removal process, reverse the outlined tasks, include the installation of a new oil filter, wait for the RTV to set for at least half an hour, join the battery terminals if required to perform re-learn procedures.
