Upper - 2WD
Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar® Threebond Engine RTV Sealant may result in engine fluid leakage.
Clean the upper and lower oil pans, timing chain cover, rear seal retainer and engine block mating surfaces thoroughly with isopropyl alcohol in preparation for sealant application. All surfaces that seal with RTV must be oil and contamination free to ensure proper adhesion of the RTV to the mating surface to prevent leaks.
Following the application of Mopar® Threebond Engine RTV Sealant to the gasket surfaces, the components must be assembled within 20 minutes and the attaching fasteners must be tightened to specification within 45 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® Threebond Engine RTV Sealant to the upper oil pan as shown in the following locations:
- Oil pan to engine block flange (1)
- Two timing cover to engine block T-joints (2)
- Two rear seal retainer to engine block T-joints (3)
CAUTION:Make sure that the rear face of the oil pan is flush to the transmission bell housing before tightening any of the oil pan mounting bolts. A gap between the oil pan and the transmission could crack the oil pan or transmission casting.
- Install the oil pan to the engine block and flush to the transmission bell housing. Secure the oil pan to the engine block with nineteen M8 oil pan mounting bolts (1) finger tight.
- Install four transmission to the engine oil pan bolts (1) and tighten to 55 N.m (41 ft. lbs.).
- Tighten the nineteen previously installed M8 oil pan mounting bolts (1) to 25 N.m (18 ft. lbs.).
- Install two M6 bolts (1) to the rear oil seal retainer flange and tighten to 10 N.m (89 in. lbs.).
- Install two rubber plugs (1) covering the rear oil seal retainer flange bolts.
- Clip the transmission cooler line retainer (1) to the oil pan flange.
- Install the lower oil pan. Refer to PAN, OIL, INSTALLATION .
- Align the steering gear to the bolts (1). Tighten the bolts to 319 N.m (235 ft. lbs.).
- Reconnect the EPS gear electrical connector (1).
- Install the front skid plate, if equipped. Refer to PLATE, SKID, FRONT, INSTALLATION or PLATE, SKID, TRANSFER CASE, INSTALLATION .
- Lower the vehicle.
- Install the oil indicator tube (2). Tighten the bolt (1) to 12 N.m (106 in. lbs.).
- Install the steering coupler (1) to the EPS gear (2). Tighten the pinch bolt to 49 N.m (36 ft. lbs.).
- If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to LUBRICATION/OIL - STANDARD PROCEDURE .
- Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
- Run the engine until it reaches normal operating temperature.
