EGR System Consists of:
• 1HotsideEGRvalve(noEGRcooler),ahighpressureloopwhichcontrolsexhaustgasesforproperemissionscontrolofNoxgases
• 1ColdsideEGRvalve(afterEGRcooler),alowpressureloopwhichcontrolsexhaustgasesforproperemissionscontrolofNoxgaseslocatedafterDOC+DPFfilter
• EGRcooler(controlstemperatureofexhaustgasestotheairintaketotheengine)–lowpressurelooponly
• 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. Removeplasticenginecover.3. Ifengineishot,theEGRsystemmustbecooled–seenotestep8.

Before step 9 can proceed, ignition must be off for the EGR system to be cooled. Turn valve to exhaust on EGR manifold, open canister air valve, close canister fluid valve and flush cooler with air for 2 minutes.
