  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Remove the crankshaft timing pulley.
  6.  
  7. Drain the engine oil.
  8.  
  9. If equipped with 4WD, remove the front differential.
  10.  
  11. If equipped with A/T, remove the oil cooler tube and clamp.
  12.  
  13. Remove the stiffener plate.
  14.  
  15. Unbolt the flywheel housing dust cover.
  16.  
  17. Disconnect the starter wire clamp.
  18.  
  19. Remove the crankshaft position sensor.
  20.  
  21. Unbolt and lower the oil pan.
  22.  
  23. Using SST 0903200100 or equivalent and a brass bar, separate the oil pan from the cylinder block.
  24.  

To install:

  1. Use a razor blade or equivalent to scrape the cylinder block and oil pan mating surfaces of any old sealing material. All traces of the old gasket and sealer must be removed.
  2.  
  3. Clean the pan thoroughly, using solvent if necessary. If the pan has a magnet in it, examine it closely. Excess metal is a sign of engine wear. A few slivers are normal. Use good judgment in relating the amount of debris to the amount of time the pan has been in place.

2UZ-FE Engine

Like some of the other Toyota truck engines, the 2UZ-FE engine uses a two-piece oil pan, separated by a baffle plate. Toyota calls the upper part of the oil pan the No. 1 oil pan, while the lower section is called the No. 2 oil pan. Please note that the oil pump is not inside the oil pan. The oil pump body bolts to the front of the engine, driven off the front of the crankshaft. For oil pump removal and installation, please see "Oil Pump," "Removal and Installation" in this section.

Oil pan removal and installation is a major job since Toyota recommends that the engine be removed from the vehicle for oil pump and oil pan service. Toyota specifies that when the oil pump is services, the oil pan and strainer should be removed and cleaned. Oil pan installation takes some care since the pan must be positioned very precisely. This is best one with the engine out of the vehicle and mounted on an appropriate engine stand. Use care and keep all parts as clean as possible.

The following procedure is based on Toyota's oil pump and oil pan service procedures that include removing the engine from the vehicle.

  1. Remove the engine from the vehicle.
  2.  
  3. Mount the engine to a suitable engine stand.
  4.  
  5. Remove the oil dipstick.
  6.  
  7. Remove the lower half of the oil pan (Toyota calls it the No. 2 oil pan). There should be 24 bolts and two nuts. The lower oil pan is sealed with a Formed-In-Place Gasket (FIPG) sealer and it may be difficult to break the seal. Toyota recommends their special tool, which is a blade, mounted in a holder that can be tapped with a hammer. The blade is positioned at the seal joint and tapped with a hammer around the oil pan flange, cutting the seal. Use care not to damage the oil pan sealing flanges, especially if using substitute tools.

  1. Between the lower oil pan and the upper oil pan (Toyota calls it the No. 1 oil pan), there is a baffle plate. Remove the seven bolts and two nuts and separate the baffle plate from the upper oil pan.
  2.  

The upper oil pan uses four different length bolts. Take care to correctly identify each bolt, its length and location. It is good practice to punch holes in a piece of corrugated cardboard to closely resemble the bolt pattern of the upper oil pan. Insert the bolts in the cardboard in their corresponding locations as they are removed. A few minutes spent at removal will save much time at installation.

  1. Remove the 18 bolts and two nuts from the upper pan. There are several points around the pan and engine block where it is approved to pry the upper pan from the block. Use care not to damage the sealing surface of the engine block or the upper oil pan.
  2.  

To install:

  1. Clean all parts well. If necessary, remove the two bolts and two nuts and remove the oil strainer and gasket. Clean the strainer well. Install the strainer with a new gasket and torque the fasteners to 66 inch lbs. (7.5 Nm).
  2.  
  3. Make sure all old FIPG sealer is removed. The pan sealing flanges and the engine block sealing surfaces must be clean of all oil and grease or the new FIPG sealer will not work. Apply a 1 / 8 inch (3mm) bead of FIPG sealer to the upper oil pan flange. Most sealers start to skin over in about five minutes so assemble the oil pan to the block without hesitation. Install the bolts just a few turns, making sure all bolt holes line up. Make sure the clearance between the rear ends of the upper oil pan and the engine block is 0.008 inch (0.2mm) or less. If the clearance is more than this, the upper oil pan will be stretched. Uniformly torque the bolts and nuts in several passes as follows:
    1. Tighten all bolts with a 10mm head to 66 inch lbs. (7.5 Nm).
    2.  
    3. Tighten all bolts with a 12mm head to 21 ft. lbs. (28 Nm).
    4.  

  4.  
  5. Install the oil pan baffle plate and tighten the nuts and bolts to 66 inch lbs. (7.5 Nm).
  6.  
  7. Install the lower oil pan. It should be clean of any old sealer and any oil or grease. Apply a 1 / 8 inch (3mm) bead of FIPG sealer to the lower oil pan flange and install the oil pan to the upper oil pan without hesitation, before the sealer starts to cure. Install the bolts just a few turns, making sure all bolt holes line up. When satisfied with the lower oil pans position, uniformly tighten the nuts and bolts, in several passes, ending with a torque of 66 inch lbs. (7.5 Nm).
  8.  
  9. Install the engine into the vehicle using the procedures found in this section.
