Before and in order to take out this cylinder head, one is required to turn off the engine and disconnect the negative cable of the battery plus drain the cooling system. Remove the upper radiator hose connection at the thermostat outlet and the heater hose at the coolant outlet. Screw and unscrew a bolt at the coil bracket and then detach the wires connected to the coil and afterward secure the coil and the bracket aside. If there are any power accessories brackets fixed on the cylinder head, they should be eliminated with out detaching the refrigerant or the power steering hoses. Subsequently, remove the manifolds and the valve cover and then use a wrench to loosen the rocker arm bolts or stud nuts so as to swung the rocker arms to one side. Take out also the push rods and put them in a box or a rack to ensure orderliness with numbers at the ends. Drop the clips of the spark plug wires at the spark plugs and any other sensor electrical connections that would hinder the removal process. Loosen the cylinder head retaining bolts in the reverse sequent to that used during the tightening process. If possible, employ an engine hoist to raise the cylinder head off the block to detach it; in the absence of an engine hoist, employing a helper, gently pry it up, refrain from using sharp wedged tools on the gasket contacting surfaces of the cylinder head and block. Subsequently place the head on a workbench then assess it, this may call for purchase of a brand new or a rebuilt head or may be sent to the machine shop for reconditioning. For installation the two surfaces of the cylinder head and block must be free from debris and parallel to each other, subsequently correctly align the gasket over the dowel pins. Slowly drop it on the block with no side to side movement in order not to misalign the gasket. A special attention must be paid to the cylinder head retaining bolts that should be coated with the engine oil, inserted into the block, and tightened in accordance with the specified sequence, in three stages up to the final torque. The remaining steps are done in a reverse sequence to what was used to remove the gasket, the radiator is refilled with coolant, the engine is started and looked for signs of leakage; some gasket manufacturers recommend that the cylinder head bolts be tightened after cooling down the engine.
