See Figures 1 through 18
- Disconnect the negative battery cable.
- Properly relieve the fuel system pressure, as outlined in Fuel System of this guide.
- Drain the cooling system into a suitable container.
- Remove the air cleaner inlet duct and air cleaner. Tag and disconnect all vacuum lines, electrical wiring and fuel lines from the throttle body.
- Remove the throttle linkage.
- Remove the accessory drive belts, as outlined in General Information & Maintenance .
- Disconnect the power brake vacuum hose from the intake manifold.
- Raise and safely support the vehicle, then separate the exhaust pipe from the manifold. Carefully lower the vehicle.
- Unbolt the power steering pump and set aside. Do NOT disconnect the fluid lines!
- Detach the ignition coil pack wiring connector, then remove the coil pack and bracket from the engine.
- Detach the cam sensor and fuel injector electrical connectors.
- For 1996-99 vehicles, remove the intake manifold.
- For SOHC engines, remove the timing belt and camshaft sprocket.
- For DOHC engines, remove the timing belt, timing belt tensioner and camshaft sprocket. Remove the inner timing belt cover.
- Remove the rocker arm (valve) cover.
- For SOHC engine, remove the rocker arm shaft assemblies.
- For DOHC engines, remove the camshaft and cam follower assemblies.
- For SOHC engines, if necessary, remove the oil separator assembly bolts, then remove the oil separator.
- For SOHC engines, unfasten the hose clamps, then disconnect the heater hoses. Remove any remaining hoses or lines.
- Use a ratchet to unfasten the cylinder head bolts, working from the center outward, then remove the cylinder head from the engine block.
- The cylinder head bolts must be inspected before they can be reused. If the threads of bolts are stretched, they must be replaced. Check for thread stretching by holding a scale or other straight edge against the threads. If all the threads do not contact the scale, the bolts must be replaced.
Use only a plastic scraper to clean the mating surfaces. NEVER use metal, as this may gouge the metal surfaces and cause leaks!
- Cover the combustion chambers, then use a plastic scraper to thoroughly and carefully clean the engine block and cylinder head mating surfaces.
- The cylinder head must be cleaned and inspected prior to installation. Please refer to the engine reconditioning portion of this guide for further details and information.
- Positon a new gasket on the engine block, then place the cylinder head over the gasket.
- Apply a thin coat of engine oil to the cylinder head bolt threads. The 4 short bolts 4.33 in. (110mm) are installed in positions 7, 8, 9 and 10, as shown in the accompanying figure.
