EGR Adapter Mack MP7 11.0L Part No. 069-3640
EGR System Consists of:
• HotsideEGRvalve(beforeEGRcooler),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

In between exhaust and intake cleaning the air pressure must first be set to zero before adding the remaining 64 oz.

Before step 10 can proceed, open EGR tool air valve, keeping the fluid valve closed, turn valve on the EGR manifold adaptor 069-3399 to exhaust and flush cooler with air for 2 minutes.

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.
