To work with the cylinder head, the first thing to do is switch off the car by unscrewing the cable from the battery's negative terminal and also drain the engine oil and cooler fluid. Take off the drivebelt, air filter housing, resonator and the intake manifolds. Detatching the wires and vacuum hose from the cylinder head then tagging them so as they can be fitted again easily. Remove the ignition coils, then the spark plugs, the catalytic converter, if the car has it or more than one, and the valve covers. Add cheek, unthread the crankshaft balancer and the oil pans. On the left side of the hull, you should remove an alternator, an oil dipstick tube, an air compressor and turn off all main engine harness connectors. For the right cylinder head, unbolt the power steering pump adapter and also the heater core tube. Take off timing chain cover, turn the crankshaft clockwise to get the #1 piston at the top on the exhaust stroke, make sure the cam phaser arrow are position properly. Depend on the degree of the operation, but you will have to take out the timing chain, oil control valves, timing chain tensioner, chain guides, camshafts, rocker arms and lash adjusters; however, be certain to keep the rocker arms and the lash adjusters aligned. Unfasten the cylinder head bolts in reverse sequence to the pattern in which it was tightened then lift off the cylinder head from the block gently but firmly using a wood block enhanced with a hammer though avoiding harm on the cylinder head or block. The cylinder head should also be checked and serviced from a worthy automotive machine shop. For installation, it is required to clean the mating surfaces of the cylinder head and the engine block using a gasket scraper and brake cleaner where necessary. Coat and pack the lifter valley with shop rags in order to avoid mixing of debris with the engine oil and ensure the surfaces are not damaged. Align the new gasket over the dowel pins, return the cylinder head to the engine block gently and start using new cylinder head bolts; do not over tighten while following a sequence of steps that might require the cylinder head to be rotated beyond the required tightness. Last of all, reattach the other parts in the reverse manner, replace the engine oil and its filter, fill in the cooling system, crank up the engine, and examine for any signs of leakage and functionality.
