To remove the components, first drain the cooling system, then take out the fan, fan shroud, and water pump, followed by disconnecting the radiator and heater hoses. Next, drain the engine oil and remove the oil filter. Remove the crankshaft pulley and vibration damper, loosening the bolt on the belt idler and swinging it aside without removing it. Unbolt and take off all accessory brackets attached to the timing cover, tying the power steering pump aside with hoses still connected. For air-conditioned models, remove the compressor/power steering pump assembly and bracket. Position the number one piston at TDC on the compression stroke, disconnect the electrical connectors at the camshaft position sensor, knock sensor, and crankshaft position sensor, then remove the front oil pan bolts. Remove the socket-head bolt from the bottom left of the front cover, disconnect the two heater hoses, unbolt the heater outlet tube, and pull it out. Remove the bolts and separate the timing cover from the engine block, gently tapping it with a soft-face hammer if necessary, while ensuring all bolts have been removed to avoid cracking the cover. For installation, use a gasket scraper to clean all surfaces of old gasket material and sealant, then inspect the gear and intermediate shaft inside the front cover. It's advisable to install a new crankshaft front seal while the cover is off, lubricating the seal lip with engine oil. Apply a small bead of RTV sealant along the oil pan-to-block joints, install the front cover gasket, and press it into place, adding more RTV sealant to the block-to-pan joints. Slide the front cover onto the engine, ensuring proper positioning with dowel pins, and install the bolts finger tight, tightening them only after the water pump is installed. Install the oil pan bolts and the remaining parts in reverse order of removal, then add engine oil and coolant before running the engine to check for leaks.

The timing cover, also referred to as the engine front cover, is tricky to remove and replace. Start with the removal of the ground strap on the battery and expulsion of the engine oil and the oil filter. For 5.0L engines, only remove the coolant by draining the cooling system. After that, it is necessary to have the engine cooling fan, drivebelt, water pump pulley, crankshaft pulley, and front oil seal off. Both the valve covers must be removed, and the transmission fluid cooler line bracket and the power steering pressure hose bracket must also be removed. The pulley of the power steering pump has to be unbolted, and the pump taken out of the way when the fluid has been drained. In 5.0L engines, the removal of the thermostat housing and water pump is also recommended. Locate the Crankshaft Position sensor connector and disconnect the electrical connector to the Crankshaft Position sensor. Then, on the 2010 and earlier models, also remove the Camshaft Position sensors. Take out the radio ignition interference capacitors, air conditioning manifold tube support bracket for 2008 and earlier 4.6L 2-valve models, as well as the four front oil pan bolts, out of which two can be studs. Remove the timing cover to engine block bolts, providing for the identification of the studs for their exact locations as well as the different length bolts. Remove the timing cover with consideration being given to the removal of bolts to avoid cracking of the engine block, and when carrying out this process, the use of a soft face hammer will be appropriate. For installation, make sure that all mating surfaces are clean; you should also install new gaskets into the grooves for the timing cover. Use RTV sealant all around the junctions of the oil pan-to-engine block, cylinder head-to-engine block, and where the timing cover joins the block and head, as well as where it meets the heads. Apply clean engine oil on the timing chains and on the crankshaft front oil seal lip, and install the timing cover if at all 5 minutes have not elapsed since applying the RTV sealant. Loosen the bolts in the reverse sequences and reinstall all the removed parts as they were originally installed. Last, put the right engine oil and fill up the cooling system for 5.0L vehicles and start the engine to verify leaks where necessary.

Remove the water pump.

Remove the bolts securing the power steering pump to the engine and position the pump aside, securing it out of the way.

Tighten the timing chain cover-to-engine block bolts in the recommended sequence and torque, then tighten the timing chain cover-to-oil pan bolts.

Install the front cover gasket on the block and press it into place, then apply a small bead of RTV sealant to the block-to-pan joints and along the front edge of the oil pan.
