2005 Buick Century Oxygen Sensor

You need to lightly oil the replacement Oil Filter gasket with clean oil and install the new oil filter, install the new oil filter and the engine oil drain plug, remove the oil drain pan, fill the engine with new engine oil, start the engine, inspect for oil leaks, turn off the engine and allow the oil a few minutes to drain back into the oil pan, remove the oil level indicator from the oil level indicator tube and clean off the indicator end of the oil level indicator with a clean paper towel or cloth, and then install the oil level indicator into the oil level indicator tube until the oil level indicator handle contacts the top of the oil level indicator tube, again remove the oil level indicator from the oil level indicator tube keeping the tip of the oil level indicator down and check the level of the engine oil on the oil level indicator. If necessary, you can adjust the oil level by adding or draining the engine oil.

You need to install the Oil Pump to the valve body and the oil pump bolts, connect the electrical connectors to the solenoid valves, the TFP manual valve position switch, and the temperature sensor and install the case side cover.

You need to coat the ends of the Pushrods with pre-lube GM P/N 1052367 (Canadian P/N 992869) or the equivalent and install the pushrods and the rocker arms to their original location, the new valve rocker arm bolts and the left or the right valve rocker arm covers.
