2005 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the oil pan on 2005 Buick Park Avenue?

  A: The replacement process starts with draining engine oil followed by right engine mount bracket removal. The first step involves disconnecting the electrical connector from the engine oil level sensor then extracting the sensor from its position on the Oil Pan. The procedure starts with torque converter cover extraction and Oil Pan bolt removal to finally extract the Oil Pan. First remove the Oil Pan Gasket then take out the oil pump pipe and screen before the Oil Pan. After cleaning the block mating areas check the Oil Pan for damage. Begin your installation by setting the Oil Pan Gasket in place before adding both the oil pump pipe and screen. Each Oil Pan bolt requires one drop of gm p/n 12345382 (Canadian P/N 10953489) before securing the bolts at 14 nm (124 inch lbs.). Fasten the torque converter cover before you install the engine oil level sensor into the Oil Pan using 20 nm of torque (15 ft. Lbs.). Install the engine oil level sensor's electrical connector while reinstalling the right engine mount bracket followed by oil filling and leak inspection after engine startup.
