Remove the fuel rails and injectors as an assembly, and release the fuel injector retaining clips to remove each injector. To install the fuel injectors, install the new upper and lower O-rings on the injectors, coat them with clean engine oil, insert them into the fuel rail and install the injectors and fuel rail assembly onto the intake manifold, tighten the mounting bolts, and reconnect the negative battery terminal.

First, relieve the fuel system pressure and disconnect the negative terminal of the battery.

For the 3.2L V6 engine, you should remove the upper intake manifold, disconnect electrical connectors from fuel injectors, detach the vent hose, remove the fuel rail support bolt, and then extract the fuel rail with injectors as a unit.

The foam insulator, gasket, and the fuel pressure sensor should be removed.

Install the support ring, upper O-ring, compensation element, and retaining ring on each injector, and install the injectors in the cylinder head.
