  Q: What precautions should be taken when handling the oil pressure relief valve and how do you properly remove and install the oil pump on Mercedes-Benz C320?

  A:

  Do not remove the oil pressure relief valve, spring, and plunger from the oil pump. Replace the oil pump as one complete assembly if the oil pressure relief valve is damaged. Begin by removing the lower and upper oil pans. Next, take out the oil pump pick-up tube. Push back the tensioner for the oil pump chain and slip the chain from the oil pump sprocket. Remove the oil pump-to-block bolts and pull the oil pump from the block. During installation of the pump, prime it by filling the housing with engine oil. To install the pump, slip the sprocket of the oil pump into the chain while supporting the pump to the block for the installation of the mounting bolts. When the bolts are finger-tight, torque the pump mounting bolts to the specified torque. The remaining installation steps are the reverse of removal.
