Removal And Installation
- Disconnect the EGR system module electrical connector.
- Disconnect the engine harness vacuum-to-EGR system module connector.
- Disconnect the EGR system module tube-to-EGR system module fitting.
- To install, tighten to 39 Nm (29 lb-ft) (4.0L SOHC).
- To install, tighten to 42 Nm (31 lb-ft) (5.4L 4V).
- Remove the 2 bolts, the EGR system module and the gasket. Discard the gasket.
- To install, tighten to 25 Nm (18 lb-ft).
- Carefully clean the EGR system module sealing surfaces.
- To install, reverse the removal procedure.
- Install a new gasket with the raised circle facing away from the EGR system module.
NOTE:
Upon installation, make sure to install the correct EGR system module mounting gasket. Even though varying gaskets may be very similar, orifice sizes may differ thus causing performance issues.
CAUTION:
Do not use metal scrapers, wire brushes, power abrasive disc or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of the old gasket.
NOTE:
The EGR system module sealing surfaces are soft metals.
