Oil Pan - Removal and Installation Procedure
OIL PAN - REMOVAL AND INSTALLATION PROCEDURE
REMOVAL
1. Open hood.
2. Disconnect battery ground cable.
3. Raise vehicle.
4. Drain oil.
5. Remove the bolts securing the rear oil pan to the tranaxle base.
6. Remove the thermactor tubes (MTA) and disconnect the rubber hose at the check valve.
7. Remove the starter motor.
8. Drain coolant.
9. Remove the heater supply tube located at the lower water pump inlet tube assembly.
10. Remove the bolt bracket at the block and water pump inlet tube assembly.
11. Remove the bracket from the air conditioning compressor line and the water pump inlet tube to the pan bottom.
12. Remove the two (2) bolts that secure the air conditioning compressor line and the water pump inlet tube to the pan bottom.
13. Remove the oil pan bolts.
Figure 2:
14. Loosen oil pan (See tabs in Figure 2).
15. Gently position or flex rear engine cover toward torque convertor enough to clear lip on the upper rear of the oil pan, and remove the oil pan.
INSTALLATION
1. Before reinstalling the oil pan, use a putty knife, scraper, or wire brush to completely remove all traces of RTV sealant from the front cover, block, rear seal retainer and oil pan sealing grooves.
2. Clean any oil residue on the cylinder block rails, front cover, rear seal retainer and oil pan throughly with brake cleaner.
CAUTION: DO NOT USE CARBURETOR CLEANER OR ANY OTHER SOLVENT THAT WILL LEAVE A HYDROCARBON RESIDUE ON THE PARTS WHICH WILL PREVENT THE RTV FROM BONDING TO THE ENGINE/OIL PAN. FAILURE TO COMPLETELY CLEAN THE SURFACE PRIOR TO THE USE OF THE BRAKE CLEANER OR USE OF THE INCORRECT SOLVENT COULD RESULT IN A REPEAT REPAIR.
3. Remove and clean the oil pick-up tube and screen assembly. After cleaning, install the pick-up and screen assembly.
4. Obtain a tube of the new grade RTV (F1AZ-19562-A) and check the expiration date before using.
WARNING: USE ADEQUATE VENTILATION WHEN APPLYING RTV SEALER.
Figure 3:
Figure 4:
5. Apply enough RTV (F1AZ-19562-A) in the oil pan to completely fill the oil pan groove, regardless of the groove size or configuration, Figures 3 and 4.
Figure 2:
Figure 3:
^ Have a bead about 0.2" (5 mm) wide by 0.25" (6 mm) high, above the pan surfaces, in both front and rear half-rounds, Figures 2 and 3.
^ Have a bead about 0.2" (5 mm) wide by 0.15" (4 mm) high, above the oil pan surfaces, along the rails, Figures 2 and 3.
NOTE: BE SURE THAT THE GROOVE IS COMPLETELY FILLED WITH RTV. MAKE CERTAIN THAT NO AIR IS TRAPPED IN THE GROOVE BECAUSE A BLOW OUT OF THE RTV MAY OCCUR WHEN THE ENGINE IS HEATED UP DURING NORMAL ENGINE OPERATIONS.
^ Have the nozzle of the RTV tube slightly above the oil pan groove.
^ Apply enough RTV to build up the bead above the oil pan surface before moving the nozzle along the groove.
Figure 4:
^ Do not lay the RTV nozzle on top of the groove because this may leave air pockets, especially in oil pans with deep grooves, Figure 4.
CAUTION: APPLYING RTV IN EXCESS OF THE SPECIFIED AMOUNT WILL NOT IMPROVE THE SEALING OF THE OIL PAN. IT COULD CAUSE THE OIL PICK-UP SCREEN TO BECOME PLUGGED WITH PIECES OF RTV.
6. Immediately, within 5 minutes of applying the RTV to the oil pan, install the oil pan against the cylinder block to prevent the RTV from skinning over. Tighten the oil pan bolts as follows:
a. Tighten the oil pan to transaxle bolts to 30-39 lb-ft (40-54 N-m).
b. Loosen the oil pan to transaxle bolts 1/2 turn.
c. Tighten the oil pan flange bolts to 15-22 lb-ft (20-30 N-m). Start in the center of the oil pan and work to the rear of the engine. Then, tighten the bolts from the center to the front of the engine.
d. Tighten the oil pan to transaxle bolts to 30-39 lb-ft (40-54 N-m).
7. Install the bracket from the air conditioning compressor line above the oil pan.
8. Install the bracket at the block and install the water pump inlet tube assembly.
9. Install the starter motor.
10. Install the thermactor (MTA) tubes and connect the rubber hose at the check valve.
11. Install two (2) bolts that secure the air conditioning compressor line and the water pump inlet tube to the pan bottom.
12. Lower the vehicle.
13. Install coolant.
14. Connect the battery ground cable.
CAUTION: DO NOT ADD ENGINE OIL UNTIL ONE HOUR AFTER THE OIL PAN BOLTS HAVE BEEN TIGHTENED. THIS ALLOWS THE OUTSIDE LAYER OF THE RTV TO SKIN OVER PRIOR TO COMING IN CONTACT WITH THE ENGINE OIL.
15. Start the engine and check for leaks.
