Ford 2L8Z-6019-AA Front Cylinder Cover

It is difficult to perform this procedure with the engine in the car because of limited clearance and therefore if a lot of work is expected to be done on the sensor, then one may have to remove the engine altogether. On the cars of the 2008 and prior years, the process will start with disconnecting the negative terminal of the battery, loosening the lug nuts of the right front wheel, lifting the vehicle with jackstands, and then finally removing the wheel. Siphon out this engine oil, then remove the drivebelt and tensioner, and the valve covers, then remove the alternator and its mounting bracket, the crankshaft pulley, and the coolant expansion tank, and finally siphon out the cooling system. You will have to unplug the crankshaft and camshaft position sensors, remove the oil pan and if necessary the air conditioning compressor to gain clearance. Slowly unscrew and unbolt the timing cover quite carefully and while doing this ensure that you mark or note down the positions of the bolts. Take out and throw away the gaskets, check/scrub all the sealing surfaces and replace the crankshaft seal if there is need for it. Implement the RTV sealant and put a new front cover gasket, place the cover back and tighten the fasteners in the right manner and order. Fit the drivebelt, then the oil pan, the crankshaft pulley and reconnect the wiring harnesses. The process of removal is fairly similar for 2009 and later models; first, the negative battery terminal and wheel are taken off, the crankshaft pulley is also removed, followed by the alternator, the drivebelt tensioner, and sensors, the pan and front cover are removed as well. Remove and clean sealing surfaces to ensure a proper fit then reinstall the crankshaft and install a new seal to the block, put new gasket, and RTV and tighten in reverse order. Then, replenish the crankcase oil, power steering and cooling systems fluids, reconnect the battery and run the engine in an effort to inspect for leaks, reprogram the idle and fuel trim of the Powertrain Control Module to get the best operation from the car.

To remove the upper Timing Cover, first improve access by removing the coolant expansion tank mounting bolt, unclipping it at the rear, and moving it aside without disconnecting the hoses. Next, unclip the power steering fluid reservoir and set it aside without disturbing the hoses. Unscrew the four bolts and withdraw the upper Timing Cover as far as possible, but support the engine since the right-hand engine mount must be removed for complete removal. Position a jack at the timing belt end of the oil pan with a block of wood between the oil pan and the jack head, then raise the jack to support the engine's weight. Mark the fitted position of the engine mounting on the inner fender before loosening and removing the nuts/bolts to lift off the right-hand mounting. Unscrew the engine right-hand mounting studs, which have Torx end fittings, and unclip the cylinder head temperature sensor wiring plug attached to the rear of the Timing Cover before lifting off the upper Timing Cover. For installation, reverse the removal procedure, ensuring the mounting studs are tightened securely and the engine mounting aligns with the previously marked position, tightening all bolts to the specified torque setting. For the middle Timing Cover, unbolt and position the coolant expansion tank and power steering fluid reservoir aside without disconnecting hoses, support the engine with a floor jack and a block of wood beneath the oil pan, unbolt the engine right-hand mount, loosen the water pump pulley bolts, and remove the auxiliary drivebelt. After removing the timing belt upper Timing Cover, unbolt the water pump pulley and the auxiliary drivebelt idler pulley, then unscrew the four middle Timing Cover bolts and withdraw the cover. Installation follows the reverse of removal, ensuring the cover edges engage correctly and adhering to specified torque settings. For the lower Timing Cover, remove the crankshaft pulley, unscrew the cover's securing bolts, and withdraw it, with installation being the reverse of removal while ensuring proper engagement of cover edges and adherence to torque specifications. For the inner shield/Timing Cover, remove the timing belt, tensioner components, and camshaft sprockets, then unscrew the two bolts securing the shield to the cylinder head and withdraw it, with installation being the reverse of removal and noting the specified torque settings for fasteners.

To remove the timing cover for 2008 and earlier models, disconnect the negative battery cable, remove the drive belt and tensioner, disconnect the crankshaft position sensor electrical connector, and move the wiring harness away from the engine cover. Remove the crankshaft position sensor, crankshaft pulley, water pump pulley, and the electrical connector to the power steering pressure switch. Move the power steering pump aside after removing its bolt, then remove the bolts securing the engine cover. For 2009 and later models, raise the vehicle and support it on jackstands, disconnect the negative battery terminal, remove the drive belt and idler pulley, and then the crankshaft pulley. Support the engine with a floor jack, remove the front engine oil seal, water pump pulley, drive belt idler pulley and bracket, and the crankshaft position sensor. Loosen the front cover bolts evenly and tap the cover sideways if necessary before removal. For installation, clean the mating surfaces, install the engine cover within four minutes of applying a 2.5 mm bead of RTV sealant, tighten all bolts to specified torque settings, and ensure to re-time the engine using a new crankshaft position sensor with the necessary alignment tool. To remove the timing chain and tensioner, apply the parking brake, jack up the front of the vehicle, and support it on jackstands. Remove the timing cover, compress the timing chain tensioner, and place a pin to hold it in the compressed position. If the ratchet mechanism needs resetting, remove the tensioner, relieve the tension on the ratchet, and then reinstall the tensioner. Remove the tensioner mounting bolts, the loose timing chain guide, and the timing chain. If necessary, the left chain guide and camshaft sprockets can be removed. For installation, remove the camshaft alignment tool if installed, loosen the camshaft sprocket bolts without removing them, and install the left chain guide, timing chain, and right chain guide. Install the timing chain tensioner, tighten the fasteners, and remove the pin to engage the chain guide. Reinstall the camshaft alignment tool and tighten the camshaft sprocket bolts while holding the camshafts in place. Finally, install the timing cover.
