SAFETY RECOMMENDATIONS

Use extreme safety measures when working around a running engine, pressurized storage vessels, and automotive chemicals.
Always block the vehicle’s drive wheels.
Ventilate the vehicle’s exhaust if engine will be started.
Always wear safety glasses, protective clothing, and gloves.

WARNING: Use only the approved Flo-Dynamics FLOCOR Flo Carbon & Oil Remover (P/N 40201131). Do not use any other non-approved cleaners or any cleaner that is flammable to prevent a health hazard or personal injury

FLUSHING PROCEDURES

Inspect engine compartment and visible components to be flushed for signs of damage or unusual wear.

FLUSHING PROCEDURES:
A.) COMPONENT FLUSHING – CAC (Charge Air Coolers), Cooling System & Components
B.) FORD 6.7L EGR VALVE AND COOLER FLUSHING

PRESSURE CHECKING A COMPONENT

NOTE: Pressure checking an EGR valve and cooler assembly is not required.
If applicable, pressure testing a component can be performed with the component installed on the vehicle.
Disconnect inlet and outlet hoses from the component being cleaned.
Connect blocked pressure adapter to one outlet and pressure adapter with gauge and regulator to the other.
Secure safety cables on each adapter to vehicle or component to prevent becoming airborne if blown off.
Connect shop air to pressure gauge, make sure valve is open, and adjust to manufacturer’s pressure check PSI rate or 15 PSI.
CAUTION: Do not exceed 25 PSI on any component.
Turn valve off and observe amount of pressure decay, noting any decrease on the gauge.
Check with manufacturer on the leakage rate that is within their acceptable limits of the component being checked.
If component leakage is acceptable, release pressure and remove safety cables and adapters.
Proceed to Procedure “A” – Performing a Component Flush.

PROCEDURE “A” – PERFORMING A COMPONENT FLUSH

Once a component has passed the pressure check procedure, perform the following: Add 10 gallons of water and 1 gallon of FLOCOR Carbon & Oil Remover (P/N 40201131) to the DCF-35 reservoir. Position the Flow Control Valve to CIRCULATE mode. Plug the DCF-35’s power cord into an electrical outlet. The green power light will illuminate. Press the RUN TIME button to select CONTINUOUS. Press the HEAT & PUMP button to circulate and heat reservoir to 130°F while adapters are being installed.
Position component with flow outlet on top and inlet on the bottom. Using the DCF-35 CAC Pressure & Flushing Adapter Kit (P/N 40100104 KIT), install adapters to component or system being flushed. Connect the DCF-35 outlet service hose (left side) to the component’s outlet adapter (top) and the DCF-35 inlet service hose (right side) to the component’s inlet adapter (bottom).
When the red HEATER ON light turns off, the reservoir temperature is at 130°F and you are ready to flush. Press the RUN TIME button to select desired flush time. Position the Flow Control Valve to FLUSH mode. When the run time has elapsed, the DCF-35 will turn off and the RUN TIME light will flash. Position the Flow Control Valve to CIRCULATE mode.
Position the component on its side with the DCF-35 outlet service hose on the top. Slowly remove the top service hose, which is connected to the DCF-35 outlet, and drain into a suitable container. Connect a wet/dry vac hose to the blow port, and the other end to the component’s top adapter. Turn on vacuum to blow cleaning fluid back into DCF-35 until air begins to enter DCF-35 reservoir, then turn off. CAUTION: To prevent cleaner foaming in reservoir do not continue to blow back into DCF-35 reservoir after component has been emptied and bubbles begin agitating cleaner.
Remove DCF-35 inlet service hose from bottom component adapter. Switch vacuum hose from the blow port to the suction port and connect the other end to the bottom component adapter. Remove top adapter to increase air flow. Turn on vacuum to air purge and position the component so the bottom adapter is at the lowest point to capture all the cleaning fluid. Air purge with vacuum for 10-20 minutes or until all moisture droplets are removed from component being cleaned. Inspect component being flushed for cleanliness and if needed select a new run time and repeat until component is at the desired cleanliness. Remove adapters. Component is ready to be re-installed. Empty wet/dry vac into a suitable container. NOTE: Dispose of used cleaner in compliance with local guidelines only. Do not dispose into local drains. See “ADDITIONAL FUNCTIONS” draining reservoir procedures to drain reservoir.

PROCEDURE “B” – FORD 6.7L EGR VALVE AND COOLER FLUSHING

CAUTION: When flushing a Ford 6.7L EGR valve and cooler, it is very important to adhere to the following: FORD DEALERSHIPS When removing EGR cooler inlet and outlet tubes. It is VERY IMPORTANT to use a Mini-Ductor https://www.rotundatechtools.com/idimdv777-ford.html (part # IDIMDV-777-FORD) or similar induction heater to heat attaching bolts red hot for about 30 seconds prior to removing, to prevent bolt breakage. If bolts break, use the ProMaxx Nino ProKit (part # PXTN200APRO) or similar to extract broken bolts, also available on https://www.rotundatechtools.com/. NON-FORD DEALERSHIPS When removing EGR cooler inlet and outlet tubes, depending on the vehicle’s age and mileage, it will be helpful to use an induction heater to heat attaching bolts prior to removing to prevent bolt breakage. If bolts unfortunately do break, there are many kits available to extract the broken bolt and re-tap the manifold threads. WARNING: To perform a Ford 6.7L EGR cooler and valve cleaning, the Ford 6.7L EGR Cooler Cleaning Kit (P/N 40100130) must be used to connect, remove, and air purge any remaining liquid in the EGR cooler assembly. THIS IS A MUST SINCE THERE IS STILL APPROXIMENTLY 1 QT OF LIQUID IN THE EGR VALVE AND COOLER ASSEMBLY. FAILURE TO REMOVE REMAINING LIQUID COULD RESULT IN ENGINE DAMAGE FROM INGESTING CLEANING FLUID.
Drive vehicle and note if any warning lights are illuminating on instrument cluster and check for any existing diagnostic codes using a Ford IDS or similar. Add 10 gallons of water and 1 gallon of FLOCOR Carbon & Oil Remover (P/N 40201131) to DCF-35 reservoir. Position the Flow Control Valve to CIRCULATE mode. Plug the DCF-35’s power cord into an electrical outlet. The green power light will illuminate. Press the RUN TIME button to select CONTINUOUS. Press the HEAT & PUMP button to circulate and heat the reservoir to 130°F while the EGR tubes are being removed and adapter hoses installed.
Remove zip-tube to enable access to EGR cooler inlet and outlet tubes. Remove inlet and outlet EGR cooler tubes, noting the above CAUTION on removing bolts.Identifying the EGR cooler inlet and outlet ports: – EGR inlet is the square port at EGR valve – EGR outlet is the round port CAUTION: EGR outlet tube metal gaskets can have sharp edges. Use caution when handling. Inspect amount of carbon build-up by using a borescope or viewing through the outlet port or by looking at the bottom corner of the EGR cooler through the round outlet port with an inspection light. Suggested EGR cooler flush times: – 90 minutes for extreme carbon build-up – 60 minutes for moderate carbon build-up (most common) – 15-30 minutes for light carbon build-up or for preventive maintenance NOTE: If performing back-to-back preventive maintenance cleanings with water and FLOCOR cleaner in the reservoir, it can be used multiple times to reduce waste.
Secure the white service hoses to the DCF-35 using the provided camlocks. Install the Ford 6.7L EGR inlet and outlet adapter hoses onto the EGR cooler. Connect the white DCF-35 outlet service hose (left side) to the black EGR outlet port adapter hose. Connect the white DCF-35 inlet service hose (right side) to the black EGR inlet port adapter hose.Open the EGR valve using one of the following methods: Remove the plastic cover and place a screwdriver as shown to hold EGR valve open. Command the EGR valve to full open using a Ford IDS or similar or scan tool.
When the red HEATER ON light turns off, the reservoir temperature is at 130°F and you are ready to flush. Press the RUN TIME button to select the desired flush time as noted when inspecting outlet cooler port above. Position the Flow Control Valve to FLUSH mode. When run time has elapsed, the DCF-35 will turn off and the RUN TIME light will flash. Position the Flow Control Valve to CIRCULATE mode.
NOTE: When separating camlock connectors, keep hose elevated and drain into a suitable container. Slowly release the camlocks on the DCF-35 outlet service hose at the EGR outlet port adapter hose. Keep the hose elevated and drain the remaining liquid into a suitable container. Release the camlocks on the DCF 35 inlet service hose at the EGR inlet port adapter hose. Keep the hose elevated and drain the remaining liquid into a suitable container. Use the following shop-vac procedure to drain the EGR cooler and adapter hoses.
SHOP-VAC DRAINING AND AIR PURGE PROCEDURE – MUST PERFORM! WARNING: FAILURE TO PERFORM THE SHOP-VAC DRAINING AND VACUUM PURGE PROCEDURE COULD RESULT IN ENGINE FAILURE DUE TO INGESTING REMAINING CLEANER IN EGR COOLER. Connect the suction port of a wet/dry vac to the EGR inlet port adapter hose and turn on for 30 seconds to initially remove cleaning fluid from EGR cooler and hoses. Remove the EGR outlet port adapter hose from the EGR outlet port to obtain maximum air flow. Turn on the shop-vac for 10 minutes to air-purge any remaining cleaning fluid from the EGR cooler. When 10-minute purge is completed, turn off vacuum and remove the screwdriver holding the EGR valve open, and replace cover. If using the Ford IDS diagnostic system or similar, remove the command to open the EGR Valve. Remove the EGR inlet port adapter hose from the EGR inlet port. Reinstall the EGR cooler tubes and components removed to access the EGR cooler. Clear all diagnostic codes using a Ford IDS or similar. Start and idle vehicle until engine is at normal operating temperatures. While idling, safely observe all components and connections for correct assembly. Test drive vehicle and perform a DEF regeneration cycle. Check for any codes and warning lights being illuminated that were not on prior. Verify EGR system is working properly and return to customer.
