2000 Chrysler Cirrus Cylinder Head Parts Questions & Experts Answers

• Q: What precautions should be taken before beginning the procedure for removing and reinstalling the cylinder head in four cylinder engine on 2000 Chrysler Cirrus?

  A: Allow the engine to cool completely before beginning this procedure. Position the number one piston at Top Dead Center. Disconnect the negative battery cable from the ground stud on the left shock tower. Drain the cooling system and remove the spark plugs. Remove the intake manifold and cover the intake ports on the manifold and cylinder head with duct tape to keep out foreign debris and contamination. Remove the bolts securing the power steering reservoir and hoses to the cylinder head and position them out of the way. Remove the exhaust manifold; it is easier to remove after the cylinder head is removed, if possible leave it attached. Disconnect the upper radiator hose from the thermostat housing and the electrical connector from the camshaft position sensor. Remove the timing belt, camshaft sprocket(s), and rear timing belt cover. On 2.0L engines, remove rocker arm shaft assemblies; on 2.4L engines, remove the camshafts, rocker arms, and valve lash adjusters. Remove the EGA valve from the cylinder head. Loosen the cylinder head bolts, 1/4-turn at a time, in the reverse order of the tightening sequence until they can be removed by hand, marking the locations of the different length bolts for reinstallation. Carefully lift the cylinder head straight up and place it on wood blocks to prevent damage to the sealing surfaces. If the head sticks to the engine block, dislodge it by placing a wood block against the head casting and tapping the wood with a hammer or by prying the head with a prybar placed carefully on a casting protrusion. Remove all traces of old gasket material from the block and head, being very careful not to gouge the sealing surfaces. Use special gasket removal solvents available at auto parts stores, and place clean shop rags into the cylinders to help keep out debris. Use a vacuum to remove any contamination from the engine and a tap of the correct size to chase the threads in the engine block. Clean and inspect all threaded fasteners for damage, and inspect the cylinder head bolt threads for "necking." If any cylinder head bolt exhibits damage or necking, it must be replaced. For installation, on 2.0L engines, install the camshaft if removed. Place a new gasket and the cylinder head in position on the engine block. Apply clean engine oil to the cylinder head bolt threads and install them back in their original locations. Tighten the cylinder head bolts in the sequence shown, progressing in three stages to the torque. After the third pass, tighten the bolts in the proper sequence an additional 90-degrees (1/4-turn) more. Before performing the final pass, mark the bolts in relation to the cylinder head and place another mark 90-degrees clockwise from the starting mark. Install the rocker arms and hydraulic valve lash adjusters. On 2.4L engines, install the rear timing belt cover, camshafts, and camshaft sprockets; on 2.0L engines, install the rear timing belt cover and camshaft sprocket. Install the timing belt, and after installation, slowly rotate the crankshaft by hand clockwise through two complete revolutions, then recheck the camshaft timing marks. Reinstall the remaining components in the reverse order of removal. Be sure to refill the cooling system and check all fluid levels. Start the engine and run it until normal operating temperature is reached, checking for leaks and proper operation.
