Before removing of the cylinder head first take off the pressure from the fuel system make the engine ready for TDC compression in cylinder no. 1 and match off the connection wire from negative terminal of battery. Remove the coolant, detract the timing chain, cam shaft, exhaust manifold and intake manifold. Unlike the specific items that were added on the next step, information related to the cylinder head should state that all the G-Particles which are related to coolant fitting, tubes, cables, hoses or wiring harnesses should be labeled and detached. The cylinder head bolt or screw fastener should be loosened by 1/4 turn each time and finally removed by the hand, if you are using a breaker bar and the hex bit and uniformly applying its torque then the desired result can be obtained without warping or cracking of the cylinder head utilising the reverse order of the sequence in which the bolts were tightened. In this process, raise the cylinder head off the engine block, especially if it is lodged in place and then, remove all the external structures for thorough washing and examining. Regarding installation, the mating surfaces for the cylinder head and block should be absolutely pure, using a gasket scraper and cleaning agents to clear off carbon and old gasket substances. Clean the components' mating surfaces; use a fine file for minor splines and consider machining for major splines. Thread the threads that are in the cylinder head bolt holes with the use of a tap and vacuum clean the same. Following this, make sure that the gasket surface of the cylinder head is clean and that the head is not warped and replace any part that you may have been compelled to uninstall. Place the new cylinder head gasket over the dowel pins at the block and then fit the cylinder head carefully over the block with no effecting the position of the gasket. It is recommended to drip a little of clean engine oil over the threaded and hardened washers of the new cylinder head bolts, while the chamfered side of the washers should face the bolt heads. Replacing the cylinder head bolts with new ones, and tighten these bolts with proper sequence and to the prescribed torque. Insatll the lifters and the camshafts follow by the timing chain, and then finally check the valve clearances. The remaining installation steps are the exact opposite of the removal process of the corresponding program. The cooling system should be refilled, a new oil filter should be put in, and oil should be added to the engine and battery reconnected as needed along with any re learn steps that may need to be carried out.
