To remove the components, then you have to first disconnect the negative cable from the battery and you should also drain the cooling system including the engine block drain plugs. Then turn the air cleaner inlet tube and air cleaner assembly, then the intake manifold counter-clockwise and remove it. Take off the drivebelts, and, if the left cylinder head is to be eliminated, undo those bolts that attach the air conditioning compressor to the block and lift the compressor away without disconnecting the hoses and put it aside. Loosen and temporarily unbolt the power steering pump from its mounting bracket although with the hoses still attached; then put it aside, together with the mounting bracket. Extract the ignition coil bracket as well as dipstick tube, as well as the right cylinder head, alternator and its accompanying bracket. Take off the ground strap and the throttle cable bracket and the exhaust manifold(s) and the valve cover(s). Then rotate the crankshaft and loosen the rocker arms together with the pushrods and unbolt the cylinder heads before lifting them up slowly, to not harm the gasket surfaces on the heads. For installation, first, clean and verify that both gasket mating surfaces are free from crack or warpage while those parts of the engine that are not covered are shield with shop cloth to avoid dropping dirt on them. As needed, remove and refit the heads, making certain all the bolt and bolt hole threads appear healthy and dry without the slightest trace of gunk or moisture: apply a light coat of oil to heads, studs and bolts, and align the head gasket with help from the dowels, then check that the mark is reading UP or TOP. Reinstall the heads and head bolts, torque them in two steps to the factory recommended torque reading and then replace all the other parts that were removed in the sequence. Check these and fill them, start the engine and check if everything is working as it should, and if there is any leakage.

Remove the drivebelt and the drive belt tensioner.

To remove valve springs, compress the springs on the first valve with a spring compressor, then remove the keepers. After that, carefully release the valve spring compressor and remove the retainer and spring.

Change the engine oil and filter.

Drop the spring seat or shim(s) over the valve guide and set the valve spring and retainer in place.

Lift the cylinder head off the engine. If it's difficult to remove, carefully pry it off. Pry against a casting protrusion, not against gasket surfaces.

New and rebuilt cylinder heads are commonly available for most engines at dealerships and auto parts stores.

Drain the cooling system.

They must be perfectly clean. Use a hard plastic or wood scraper to remove all traces of gasket and carbon, and also clean the piston crowns.

Remove the drivebelts.

Lubricate the new replacement cylinder head bolts with clean engine oil before placing them in position.

9. Remove the alternator and the lower alternator mounting bracket. 10. Remove the upper radiator hose and the coolant bypass hose. 11. Disconnect the engine coolant temperature (ECT) sensor. 12. Remove the accessory bracket. 13. Remove the thermostat housing. 14. Remove the bolts that retain the engine wiring harness to the engine brackets.

Remove the timing belt from the camshaft or oil pump sprockets.

Check the installed valve spring height with a ruler graduated in 1/32-inch increments or a dial caliper. The measurement is taken from the top of each spring seat or shim(s) to the bottom of the retainer.
