To remove the upper intake manifold, start by relieving the fuel system pressure and disconnecting the battery cable. Then, remove the air filter housing and label and disconnect the hoses and electrical connectors attached to the intake manifold and throttle body. Remove the bolts securing the EGR pipe and the brackets from the throttle body and upper intake manifold. Loosen the upper intake manifold bolts and lift the manifold from the engine. Clean the mounting surfaces and inspect the O-ring gasket. If it's in good condition, it can be reused. Install the gasket into the groove in the upper intake manifold and then install the manifold onto the lower intake manifold, tightening the bolts in a circular pattern.

Relieve the fuel system pressure.

To remove the upper intake manifold, start by relieving the fuel pressure and disconnecting the battery. Then, remove the air intake duct and filter housing.

To remove the lower intake manifold, drain the cooling system and remove the upper intake manifold. Label and detach any remaining hoses and remove the fuel rail and injectors. Remove the heater hoses and coolant hoses. Loosen the remaining manifold mounting bolts/nuts and carefully break the gasket seal. Turn the manifold over, replace the O-ring on the heater supply tube, and remove all traces of old gasket material and sealant. Clean the mating surfaces with lacquer thinner or acetone. Apply RTV sealant around the front and rear cylinder head water passages and lay the new gaskets in place. Position the manifold on the engine, aligning the gaskets and manifold with the ports in the cylinder heads. Install the fuel rail and injectors, then tighten the nuts/bolts following the recommended sequence. Refill the cooling system, run the engine, and check for leaks.

Loosen the lower intake manifold mounting bolts/nuts in reverse order until they can be removed by hand. Carefully break the gasket seal without prying between the manifold and the heads.

Check the O-rings on the intake manifold for damage or hardening. If they're OK, they can be re-used. If necessary, install new O-rings (Replace the intake manifold O-rings with new ones. Make sure they seat properly in their grooves).

Loosen the manifold bolts in reverse order and remove the manifold along with the foam insulator pad.

To remove the upper intake manifold, start by relieving the fuel system pressure and disconnecting the battery cable. Then, remove the air filter housing and label and disconnect the hoses and electrical connectors attached to the intake manifold and throttle body. Remove the bolts securing the EGR pipe and the brackets from the throttle body and upper intake manifold. Loosen the upper intake manifold bolts and lift the manifold from the engine. Clean the mounting surfaces and inspect the O-ring gasket. If it's in good condition, it can be reused. Install the gasket into the groove in the upper intake manifold and then install the manifold onto the lower intake manifold, tightening the bolts in a circular pattern.

The remaining installation steps are the reverse of removal. Start the engine and check carefully for vacuum leaks at the intake manifold joints.
