To extract the cylinder head, one will require use of a Tone bit since the head bolt needs this type of bit, use of Allen wrench may round the bolt head. Start by removing the negative terminal of the battery and then evacing the cooling system. After that, you should take off the valve covers, the rocker links or arms along with the pushrods, the intake manifold together with the drivebelt. If left cylinder head is being removed then remove the air conditioning compressor with the lines used for refrigerant still connected also the power steering pump and its bracket but without disconnecting the hoses used. When replacing the right cylinder head, the alternator and bracket needs to be taken off. If there is a wiring harness secured to the rear of either the lower or upper cylinder head, (depending on the model) then remove the tape from it to disconnect it. Pull out the spark plugs and exhausts manifolds, the cylinder head bolts should be thrown away and new ones introduced after loosening the nuts gradually. Lever the cylinder head off the engine, using the crow's foot if further aid is required, against the edge of a casting lug. For installation, all the gasket material and clean all the parts with solvent, no oil should be left on the gasket mating surfaces. Tap the threads in the head bolt holes with a tap and look for any signs of coolant, oil or any other foreign substance. Place the new gaskets on the dowel pins on the block, do not use the sealant at this point, and align the FRONT TOP. Take the heads and new head bolts and put them in place to the required torque. You should put silicone sealant on the block and cylinder head mating surfaces and at the same locations put the intake manifold gasket with sealant. Placed the intake manifold on the engine, put all the intake manifold bolts, and tighten this bolt in the right sequence. The rest of the installation is done in a process of removal in a reverse order; start the engine and look for any signs of oil, coolant or vacuum leaks.
