Hyundai 22100-2B701 Head Assembly-Cylinder

Before you tackle the cylinder head you should relieve the fuel system pressure then disconnect the connection from the negative terminal of the battery and should drain the engine coolant. If desired the intake manifold can be left in but perform all the necessary steps to remove it. Remove coolant hoses from the cylinder head as to detach the timing chain and the camshaft sprockets, and finally lift the car on jack stands to remove the exhaust manifold. Remove the cylinder head electrical connectors by simply labeling and unplugging them off, next are the Oil Control Valves and both Camshaft Position sensors as well as the fuel injector and rail assembly. Unfasten the cylinder head bolts with a turning angle of 1/4-turn increments so that they can be easily remove without the use of tools, always untighten in an opposite sequence of the tightening pattern so that the warping or cracking of the cylinder head is avoided. With help, ease the cylinder head off the engine block: they may need a nudge, and strip any other external parts to clean them to the best of your ability. Each head's gasket surfaces are vertically checked, a feeler gauge is inserted to gauge the clearance; if beyond standard, resurfacing or replacement is done. Be sure to check around the valve seats and the seat inserts for cracks and signs of coolant leakage. Ensure the surfaces of the cylinder head to be mated are clean by using the gasket scraper and brake system cleaner, and to prevent entry of debris you stuff the cylinders with clean shop rags. Look for broken edges, missing scales or deep ruptures in the areas that are going to mate, with a file for slight damage and with machining in case the damage if severe. Stake the threads in the cylinder head bolt holes with a tap and blow clean with the compressed air. Using a smooth wire status, clean the threads of each bolt and replace any type of bolt seen to be bad. Replace the removed components in the cylinder head, put a generous amount of liquid gasket on the front corner edges of the gasket, then properly orient the new gasket, and place it firmly over the dowel pins. Place the cylinder head on the block such that the gasket is still in position; coat the threads and head of the bolts with clean engine oil, install new head bolts and washers and bring the bolts just snug with your fingers. The user is to proceed as instructed below to further tighten the bolts to the right torque with another additional of 90 degree. If new bolts/fasteners are used, it should adhere to the recommended torque sequence. The rest of the installation is the reversal of the procedure of removal, and after replacing the engine oil and filter, filling up the cooling system, start the engine and look for any signs of leakage.

Install the timing belt.

Clean the exhaust manifold and intake manifold stud threads with a wire brush.

A valve spring compressor with a special adapter is needed to compress the spring and allow for the removal of the keepers from the valve stem.

Clean out the cylinder head bolt holes with a suitable tap and blow them out with compressed air to ensure they are clean and dry.
