2010 GMC Yukon Engine Mount

You can apply clean engine oil to the NEW Oil Filter seal, install the NEW oil filter, remove the oil drain pan from under the vehicle, fill the engine with new engine oil, 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 indicator tube, 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, remove the oil level indicator from the oil level indicator tube keeping the tip of the oil level indicator down, check the level of the engine oil on the oil level indicator, adjust the oil level by adding or draining oil, check for oil leaks, close the hood.

Contamination of the Oxygen Sensor can result from the use of an inappropriate RTV sealant (not oxygen sensor safe) or excessive engine coolant or oil consumption. Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.

You can install the rocker arm cover, the number one cylinder spark plug, the rocker arm bolts, the rocker arms, the rocker arm pivot support, and the Pushrods.
