  Q: How to replace the oil pan on Cadillac DeVille?

  A: Engine replacement starts with draining engine oil followed by removing the front exhaust manifold pipe. Start by disconnecting the electrical connector that controls the engine oil level sensor then take out the sensor from the pan. Start by removing all Oil Pan bolts while keeping track of the reusable Oil Pan Gasket condition. Removing the gasket from its groove should only happen if necessary repair. After taking off the Oil Pan you should clean it and perform an inspection. When replacing a new Oil Pan seal, remove all oil residue from the groove then guide the seal through the pan in both vertical directions. Position the Oil Pan to the crankcase by using the right fasteners in their designated positions because replacement fasteners need an exact part number for this application. The installation of Oil Pan retaining bolts needs a two-step torque sequence: apply 8 nm (71 lb in) in the first installation then finish with 12 nm (106 lb in). Place the engine oil level sensor inside the Oil Pan while applying 20 nm (15 ft. Lbs.) torque force then attach the electrical connector to the sensor. Now install the front exhaust manifold pipe while filling engine oil before conducting leak checks after the engine starts.
