To remove the lower and upper oil pan sections, either remove the engine from the vehicle or raise the engine. Next, take off the oil pump by removing the bolts. Pull the oil pump intermediate driveshaft out of the engine. For installation, fill one of the pump ports with clean engine oil and rotate the pump by hand to prime it. Insert the intermediate drive shaft into the engine, ensuring it engages the oil pump drive and that the travel limit clip is in place, positioned closer to the camshaft position sensor end. Install the oil pump on the block with a new gasket, ensuring it engages the driveshaft, then install and tighten the oil pump bolts to the specified torque. The remainder of the installation follows the reverse order of removal. After completing the installation, run the engine and ensure that oil pressure rises to normal quickly; if it does not, stop the engine and investigate the cause to prevent severe engine damage from insufficient oil pressure.
