  5. Start the engine and warm it up to normal operating temperature.
  6. Check the engine oil pressure with engine running under no-load.
    NOTE:

    If difference is extreme, check engine oil passage and oil pump for engine oil leakage. 

  7. After the inspections, install oil pressure switch as follows:
    1. Remove old liquid gasket from oil pressure switch and the mating surface.
    2. Apply liquid gasket and tighten oil pressure switch to the specification.
