  Q: How to replace the oil pan on Buick Park Avenue?

  A: You need to drain the engine oil before starting the right engine mount bracket replacement process. The procedure requires users to first disconnect the electrical connector from the engine oil level sensor while removing the sensor from its position on the Oil Pan. So you must start by taking out the torque converter cover and then move on to the Oil Pan bolts until you can remove the Oil Pan. Separate the Oil Pan Gasket from the screen and oil pump pipe. Then extract the Oil Pan. The mating surfaces of the cylinder block need cleaning while checking the overall condition of the Oil Pan. Begin by installing the Oil Pan Gasket and afterward install the oil pump pipe and screen before fitting the Oil Pan. Place one drop of gm p/n 12345382 (Canadian P/N 10953489) on each bolt before tightening them to 14 nm (124 inch lbs.). After reinstalling the torque converter cover proceed to install the engine oil level sensor into the Oil Pan while tightening it to 20 nm (15 ft. Lbs.). Connect the electrical line to the engine oil sensor port before replacing the right mount bracket and filling the engine oil reservoir and inspecting for leaks when starting up the engine.
