Exhaust Gas Recirculation (EGR) System Module

Removal and Installation

1. Disconnect the EGR system module electrical connector.

2. Disconnect the engine harness vacuum-to-EGR system module connector.

3. Disconnect the EGR system module tube-to-EGR system module fitting.
   • To install, tighten to 40 Nm (30 lb-ft).

4. 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.

   Remove the 2 bolts, the EGR system module and the gasket. Discard the gasket.
   • To install, tighten to 25 Nm (18 lb-ft).

5. NOTICE: 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.

   Carefully clean the EGR system module sealing surfaces.

6. To install, reverse the removal procedure.
   • Install a new gasket with the raised circle facing away from the EGR system module.
