    7.  
  7. Lower the jack from the transaxle.
    8.  
  8. Lower the vehicle, and fill the crankcase with the appropriate amount of engine oil. Refer to the Capacities chart.
    9.  
  9. Connect the negative battery cable, start the engine and check for leaks. If all is well, raise the vehicle slightly and install the engine under cover.
    10.  
  10. Recheck the engine oil level, top off if necessary.
    11.  

7A-FE Engine

See Figures 8 through 17

On the 1993-97 7A-FE engine, a 2 piece oil pan assembly is used. The No. 1 oil pan (upper) is made of aluminum and the No. 2 oil pan (lower) is made of steel. The upper oil pan section is secured to the cylinder block and the transaxle housing, increasing rigidity.
