Service repair of the engine front cover begins with disconnecting the battery ground cable together with draining the cooling system. Start by removing the crankshaft front seal followed by unfastening the wiring harness bracket from the front cover with the nut removed while extracting the five
Oil Pan-to-front cover bolts. Begin by removing the lower radiator hose followed by removal of the drive tensioner bolt while also disconnecting the heater hose from the coolant pump. To proceed with the procedure start by removing the wiring harness retainer together with the generator electrical connectors and crankshaft position (CKP) sensor electrical connector before extracting the three generator bracket bolts and the bracket itself. Unscrew the coil bracket-to-left-hand (LH) accessory drive bracket bolt before extracting the four bolts which can be followed by removing the LH accessory drive bracket. The technician disconnects both upper radiator hose and heater hose from the
Thermostat Housing while removing engine coolant temperature (ECT) sensor electrical connector and discarding CKP sensor wiring harness retainers. Extract the bypass hose clamp from the coolant pump end while removing the thermostat housing through its three mounting bolts and retain the stud bolt locations for later reinstallation. Disassemble the ten bolts from the engine front cover then take out the cover and its gasket which you must throw away. The sealing surfaces require cleaning through the combination of a plastic scraping tool and a silicone gasket remover and metal surface prep but prohibit the use of abrasive tools. Place the new front cover gasket onto its position before sealing the oil pan and engine block surfaces at five spots with silicone gasket material. Take the ten stud bolts back to their factory positions before placing the engine front cover and tightly installing the bolts at 19 Nm (14 ft. lbs.). After securing three bolts to 11 Nm (8 ft. lbs.) on the thermostat housing begin to position the bypass hose clamp and reconnect both upper radiator hose and heater hose to the thermostat housing. Connect the ECT sensor electrical connector followed by new wiring harness retainer setup before installing the CKP sensor electrical connector and positioning its wiring. Place the LH accessory drive bracket into position before installing four bolts that need to be tightened to 42 Nm (31 ft. lbs.). The technician secured the
Ignition Coil bracket-to-LH accessory drive bracket bolt at 10 Nm (89 inch lbs.) before setting the generator bracket and fastening its three bolts to 42 Nm (31 ft. lbs.). Connect the generator electrical connectors while tightening the wiring harness retainer to 8 Nm (71 inch lbs.). Install the heater hose to the coolant pump. Position the accessory drive belt tensioner before installing its bolt then apply torque of 47 Nm (35 ft. lbs.). Attach the lower radiator hose and secure the five cylinder block cradle-to-front cover bolts with washers at 10 Nm (89 inch lbs.) while bolts without washers should be tightened to 14 Nm (10 ft. lbs.). The last steps involve fitting the wiring harness bracket and installing the nut which requires torque of 20 Nm (15 ft. lbs.). Next, install the crankshaft front seal after reconnecting the battery ground cable and filling the engine cooling system.
