Nissan 31390-41X07 Oil Pan

Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands. Remove the engine under-cover if equipped. Drain the engine oil and remove the oil filter. Unbolt and remove front exhaust pipe from the exhaust system. Detach the bellhousing cover. On 2WD models, remove the front suspension crossmember from beneath the oil pan. On 4WD models, remove the front axle/differential assembly. Remove the oil pan bolts, following the reverse of the tightening sequence. Detach the oil pan. Don't pry between the pan and engine block or damage to the sealing surfaces may result and oil leaks could develop. If the pan is stuck, dislodge it with a soft-face hammer. Use a gasket scraper to remove all traces of old gasket material and sealant from the engine block and pan. Clean the mating surfaces with lacquer thinner or acetone. Ensure that the threaded holes in the engine block are clean. Apply a continuous 5/32-inch (3.5 mm) bead of RTV sealant to the inner sealing surface of the oil pan. Install the oil pan and tighten the bolts in three or four steps following the sequence to the specific torque. The remaining installation steps are the reverse of removal. Allow at least 30 minutes for the sealant to dry, add oil and a new oil filter, start the engine and check for oil pressure and leaks.

Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands. Remove the engine under-cover (if equipped).

Before installation, use a scraper to eliminate all old gasket material and sealant from the upper aluminum section of the oil pan, the lower steel pan, and the engine block. Clean the mating surfaces with lacquer thinner or acetone and ensure the threaded bolt holes in the block and aluminum section of the oil pan are clean.
