To remove the engine components, first drain the engine coolant and disconnect the cable from the negative battery terminal. Next, remove the air cleaner assembly along with the air intake duct and heat tube, then loosen the accessory drivebelt idler and remove the drivebelt. If the left cylinder head is being removed, and if equipped with power steering, take off the pump mounting bracket attaching bolts while leaving the hoses connected, and set the pump/bracket assembly aside to prevent fluid leakage. If air conditioning is present, remove the mounting bracket attaching bolts and position the compressor aside with hoses still connected. For the right cylinder head removal, disconnect the thermactor diverter valve and hose assembly at the bypass valve and downstream air tube, then remove the assembly. Continue by removing the accessory drive idler, alternator, thermactor pump pulley, pump, alternator bracket, PCV valve, intake manifold, valve cover(s), and exhaust manifold(s). Remove the pushrods while noting their positions, then take out the cylinder head attaching bolts and remove the cylinder head(s), discarding the bolts as new ones are required for reinstallation. Discard the old cylinder head gasket(s) and follow the procedures for cylinder head disassembly and inspection. For installation, position new head gasket(s) on the cylinder block using dowels for alignment, then place the head(s) on the block. Apply a thin coat of pipe sealant to the threads of the short cylinder head bolts, avoiding sealant on the long bolts. Lightly oil the flat washers and install them along with the cylinder head bolts, ensuring to use new bolts. Tighten the attaching bolts in the correct sequence according to torque values, and complete the remaining installation steps in reverse order of removal. Use the proper coolant when refilling the cooling system, change the engine oil and filter, then start the engine and check for leaks.
