Oil Pan: Service and Repair

Removal
1. Drain the crankcase and the cooling system.
2. Remove the upper intake and throttle body assembly.
3. Raise the vehicle on a hoist. Disconnect the starter cable at the starter and remove the attaching bolts and starter.
4. Remove the engine front support insulator-to-support bracket nuts and washers on both supports. Raise the front of the engine with a transmission jack and wood block and place 25.4 mm (1-inch) thick wood blocks between the front support insulators and support brackets. Lower the engine and remove the transmission jack.
5. Remove the oil pan attaching bolts and lower the pan to the crossmember. Remove the two oil pump bolts and the one oil pump inlet tube nut, and drop the assembly in the oil pan. Remove the oil pan. Remove the oil pan gasket. Remove the inlet tube and screen from the oil pan.

Installation
1. Clean the gasket surfaces of the oil pump, oil pan, and cylinder block. Clean the seal grooves.
2. Apply a pressure-sensitive silicone-based adhesive (such as G.E., Dow, Loctite, or equivalent) to block rails and front cover oil pan.

3. Apply a bead of RTV Silicone Rubber or equivalent to parting line between front cover and block (two places) and to tapered ends of rear seal portion of gasket (two places). Immediately install gasket to block to facilitate pan installation.
4. Clean the inlet tube and screen assembly and place it in the oil pan.





5. Position the oil pan under the engine. Install the inlet tube and screen assembly on the oil pump with a new gasket. Tighten the two screws to 14-20 N-m (10-15 ft-lb) and one nut to 30-43 N-m (22-32 ft-lb). Position the oil pan against the cylinder block and install stiffener (reinforcement) plates and the attaching bolts. Tighten the bolts in sequence to 16-24 N-m (12-18 ft-lb).
6. Raise the engine with a transmission jack and remove the wood blocks from the engine front supports. Lower the engine until the front support insulators are positioned on the support brackets. Install the washers and nuts on the insulator studs and tighten the nuts to 73-100 N-m (54-74 ft-lb).
7. Install the starter and connect the starter cable.
8. Lower the vehicle. Install the radiator.
9. Install the upper intake and throttle body assembly.
10. Fill the crankcase and cooling system.
11. Start the engine and check for coolant and oil leaks.
