Install a new oil filter housing seal (2) onto the oil filter housing.
Clean the cylinder block and bedplate mating surfaces with isopropyl alcohol in preparation for sealant application.
CAUTION:
Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar® Engine Sealant RTV Silicone Rubber Adhesive may result in engine fluid leakage.

CAUTION:
Following the application of Mopar® Engine Sealant RTV Silicone Rubber Adhesive to the gasket surfaces, the components must be assembled within 10 minutes and the attaching fasteners must be tightened to specification within the next 10 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.
Apply a 2 to 3 mm wide bead of Mopar® Engine Sealant RTV Silicone Rubber Adhesive to the two cylinder block to bedplate T-joints (1) as shown in illustration.

Allow the oil pump to center itself on the crankshaft and position the oil pump so that the distance between the oil pump flange and the alignment fixture is equal on both sides (1).
NOTE:
Do not force the oil pump flange down against the alignment fixture.
While maintaining this alignment, tighten the seven bolts in the sequence shown in illustration to 10 N.m (89 in. lbs.).

CAUTION:
When the timing belt is removed and the cylinder head is still installed, DO NOT rotate the camshaft or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.
If removed, install the front crankshaft oil seal (1). Refer to SEAL, CRANKSHAFT OIL, FRONT, INSTALLATION .
Install the timing belt and sprockets. Refer to SPROCKET(S), TIMING BELT AND CHAIN, INSTALLATION .
NOTE:
The oil pressure switch has a lock patch on the threads and if removed can not be reinstalled.
If removed, install a new oil pressure switch. Refer to SWITCH, OIL PRESSURE, INSTALLATION .

NOTE:
A new engine oil pump must be primed with oil before engine operation.
If installing a new engine oil pump, remove the oil filter and prime the new pump through the oil filter housing with approximately 0.5 liter (0.5 quart) of engine oil. Direct the oil into the side port (filter inlet) (1) as shown in illustration and not the center port (filter outlet). Refer to FILTER, ENGINE OIL, REMOVAL .
If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to STANDARD PROCEDURE .
Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
Fill the cooling system. Refer to STANDARD PROCEDURE .
Start and run the engine until it reaches normal operating temperature. Check cooling system for correct fluid level. Refer to STANDARD PROCEDURE .
NOTE:
The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system. For example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components. Refer to appropriate Engine Electrical Diagnostics article.
