What precautions should be taken when removing and installing cylinder heads in V6 engine on Lincoln Navigator?

The cylinder heads should not be removed until the engine has cooled, or warpage of components will occur. First, remove the battery cable negative terminal, and eliminate the valve covers, pushrods, and rocker arms. After that, remove the upper intake plenum and lower intake manifold as well as loosening the exhaust manifold of the head scheduled for removal. For the left cylinder head, remove the power steering reservoir with the hoses still connected, and the drivebelts, and the air-conditioning compressor/power- steering pump bracket. For the right cylinder head, unplug the alterner wiring and remove the bolts but keep the alterner bracket on if possible. The cylinder head bolts should be loosened at intervals of two clockwise, and untightened in counter clockwise sequence to ease their total removal; the old bolts are discarded and it is also important to remove wire harness bolts at back heads of the head. Remove the cylinder heads gently off the engine by putting a piece of wooden block under it and apply a hammer gently if required, and then place the cylinder heads on wooden blocks so that there is no further damage. Make sure the mating surfaces on the cylinder heads and engine block are free of contaminants before assembly, you provide gasket scraper and solvent to clean them. One should look for signs of damage on the surfaces and use a tap to remove debris in the bolt holes. Align the new gasket and place it over the dowel pins; subsequently, install the cylinder heads over the engine block without shifting the gasket. Treat the threads of new cylinder head bolts with a little oil before fitting them, then tighten them only with your fingers until they are firm and using the correct torque sequence without removing them all at one time. The rest of installation procedure is executed oppositely to the removal process, after the installation is completed change the engine oil and filter before start the engine and check the leaks.
