  To remove the cylinder head, you should begin with the removal of the cable from the terminal of the battery and also the draining of the cooling system. It is now possible to pull out the air cleaner assembly and it is essential to label the hoses with numeral or colorful tapes for the reconnection. Easily un-bolt the exhaust manifold from the cylinder head and also take out the Intake Manifold. Remove the electrical connectors and the radiator hose at the left end of the cylinder head; and unbolt the ground strap at the right end. Remove the rocker arm cover assembly, then the rocker arms and push rods must be removed. With the new head gasket, reflect on the cylinders and also bolt pattern in cardboard to help in arrangement of the cylinder head bolts. Tighten the head bolts slightly and then unscrew them one by one and push them unto the cardboard you have arranged in a manner that corresponds with its installation order. Strike the cylinder head gently with a hammer and wooden block do not pry the head upward at all only push lightly at the overhang at the thermostat end, set the cylinder head on a wooden block to prevent it from being damaged. To that end, pull out and then throw away the current cylinder head gasket. Should you be fitting a new cylinder head, transfer all external parts from the old head stuff clean rags in the cylinders so as not to let debris fall in and clean all gasket surfaces. New gasket should then be placed on the cylinder block in the right position before easing the cylinder head on to it across the dowel pins.

Engines with displacements of 1984cc and 1985cc should have the cylinder head bolt torqued in at least three steps in the sequence prescribed below. For 1986 and 1987 engines, gradually tighten the bolts in the sequence described to the initial torque number and then to the second number for all of the bolts except no 9 which should be tightened to the indicated torque number.
