EGR Adapter Mercedes MBE900 7.2 Liter (2004-2006)

Part No. 069-3675

EGR System Consists of:

• HotsideEGRvalve(afterEGRcooler),whichcontrolsexhaustgasesforproperemissionscontrolofNoxgases

• EGRcooler(controlstemperatureofexhaustgasestotheairintaketotheengine)• EGRtemperaturesensor(measuresEGRcoolerexhausttemperatureandefficiency)

These items are critical for proper emissions management control and must be cleaned on a regular basis for optimum efficiency.

First steps before any service can be performed:

1. AddPart#400-3012DieselTune™MaxStrengthFuelInjectorCleanertothevehicle’sfueltank.2. Removeplasticenginecoverandfoaminsulator.3. Ifengineishot,theEGRsystemmustbecooled–seenoteinstep8

Note: At any time during the intake service you hear a diesel knock sound, turn manifold valve to off for 2 minutes. After two minutes then turn manifold valve to intake and continue service. Let the vehicle operate for an additional 5 minutes and rev the engine several times to clear all residual fluid.
