Removal & Installation
- Properly relieve the fuel system pressure.
- Disconnect the negative battery cable and drain the cooling system.
- Remove the air cleaner and air flow meter assembly and the inlet air ducting. Disconnect the accelerator cable.
- Disconnect the radiator and heater hoses.
- Label and disconnect all necessary electrical connections and vacuum hoses. Disconnect the fuel lines.
- Remove the ignition coil pack assembly with the spark plug wires.
- Disconnect the exhaust pipe from the exhaust manifold and remove the exhaust manifold from the cylinder head.
- Remove the cylinder head cover and the timing belt front covers.
- Rotate the crankshaft, in the normal direction of rotation, until the No. 1 cylinder piston is at TDC on the compression stroke. Make sure the timing marks on the crankshaft and camshaft sprockets are properly aligned and mark the direction of rotation of the belt.
- Loosen the timing belt tensioner lock bolt. Pry the tensioner outward with a prybar and tighten the lock bolt with the tensioner spring fully extended. Remove the timing belt.
- Remove the intake manifold-to-engine block bracket.
- When everything is disconnected, loosen the cylinder head bolts in the reverse of the tightening sequence in steps. Remove the bolts and lift the head off the engine.
- If necessary, remove the intake manifold from the cylinder head.
- Thoroughly, clean the cylinder head and the block contact surfaces. Examine the head gasket and check the cylinder head for cracks. Check the cylinder head for warpage using a feeler gauge and straightedge. The maximum allowable distortion is 0.006 in. (0.15mm).
- If removed, install the intake manifold using a new gasket. Tighten the intake manifold bolts to 19 ft. lbs. (25 Nm).
- Clean the cylinder head bolts and the threads in the block. Make sure the bo
