Dealer Service Instructions for:

Safety Recall W79 / NHTSA 20V-699 Diesel EGR Cooler

 

NOTE: Added Inspection LOP

 

Remedy Available

2014 – 2019(WK)JeepeBay logo Grand Cherokee

 

NOTE:  This recall applies only to the above vehicles equipped with a 3.0L Eco Diesel Engine (sales code EXF).

NOTE:  Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.

 

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle  inventory.  Federal law requires you to complete this recall service on these  vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The Exhaust Gas Recirculation (EGR) cooler on about 34,000 of the above vehicles may be susceptible to thermal fatigue.  Thermal fatigue may cause the cooler to crack internally over time.  An EGR cooler with an internal crack will introduce pre-heated, vaporized coolant to the EGR system while the engine is running. In certain circumstances, this mixture interacts with other hydrocarbons and air in the system, potentially resulting in combustion within the intake manifold, which may lead to a vehicle fire.  A vehicle fire may increase the risk of injury to occupants and persons outside of the vehicle, as well as property damage.

 

Repair

Replace the EGR cooler assembly. If Malfunction Indicator Lamp (MIL) is illuminated, inspect vehicle for either or both P0299 and P2D2F DTCs.  If present, also perform section B. Intake Manifold Inspection and Leak Test. Replace Intake Manifold, if perforation is identified using test procedure.

 

NOTE: If a vehicle had a new Mopar provided replacement engine please inspect for a white or yellow mark on the front fuel pump cover (Figure Below). If a yellow or white mark is present it’s an indication the updated EGR cooler has been installed, NO EGR cooler replacement is necessary.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that repair is required and the vehicle must be held overnight.

NOTE:  Evacuating or purging air from the cooling system involves the use of a pressurized air operated vacuum generator. The vacuum created allows for a quick and complete coolant refilling while removing any airlocks present in the system components.

 

WARNING:  Antifreeze is an ethylene glycol base coolant and is harmful if swallowed or inhaled. If swallowed, drink two glasses of water and induce vomiting. If inhaled, move to fresh air area. Seek medical attention immediately. Do not store in open or unmarked containers. Wash skin and clothing thoroughly after coming in contact with ethylene glycol. Keep out of reach of children. Dispose of glycol based coolant properly. Contact your dealer or government agency for location of collection center in your area. Do not open a cooling system when the engine is at operating temperature or hot under pressure; personal injury can result. Avoid radiator cooling fan when engine compartment related service is performed; personal injury can result.

 

WARNING: WEAR APPROPRIATE EYE AND HAND PROTECTION WHEN PERFORMING THIS PROCEDURE.

 

NOTE: The service area where this procedure is performed should have a minimum shop air requirement of 80 PSI (5.5 bar) and should be equipped control should be set to the heat position (ignition may need to be turned to  with an air dryer system.

 

NOTE: For best results, the radiator should be empty. The vehicle’s heater the on position but do not start the motor).

 

b. Refer to the Mopar Essential Tools and Service Equipment Tool, UView Airlift™ Cooling System Refill 399-550000 or equivalent and follow tool’s operating manual for specific assembly steps.

c. Choose an appropriate adapter cone that will fit the vehicle’s radiator filler neck or reservoir tank.

d. Attach the adapter cone to the vacuum gauge.

e. Make sure the vacuum generator/venturi ball valve is closed and attach an airline hose (minimum shop air requirement of 80 PSI (5.5 bar) to the vacuum generator/venturi.

f. Position the adaptor cone/vacuum gauge assembly into the radiator filler neck or reservoir tank. Ensure that the adapter cone is sealed properly.

g. Connect the vacuum generator/venturi to the positioned adaptor cone/vacuum gauge assembly.

h. Open the vacuum generator/venturi ball valve.

 

NOTE: Do not bump or move the assembly as it may result in loss of vacuum. Some radiator overflow hoses may need to be clamped off to obtain vacuum.  

 

i. Let the system run until the vacuum gauge shows a good vacuum through the cooling system. Refer to the tool’s operating manual for appropriate pressure readings.

 

NOTE:  If a strong vacuum is being created in the system, it is normal to see the radiator hoses collapse.  

 

j. Close the vacuum generator/venturi ball valve.

 

k. Disconnect the vacuum generator/venturi and airline from the adaptor cone/vacuum gauge assembly.

l. Wait approximately 20 seconds, if the pressure readings do not move, the system has no leaks. If the pressure readings move, a leak could be present in the system and the cooling system should be checked for leaks and the procedure should be repeated.

m. Place the tool’s suction hose into the coolant’s container.

 

NOTE: Ensure there is a sufficient amount of coolant, mixed to the required strength/protection level available for use. For best results and to assist the refilling procedure, place the coolant container at the same height as the radiator filler neck. Always draw more coolant than required. If the coolant level is too low, it will pull air into the cooling system which could result in airlocks in the system.  

 

n. Connect the tool’s suction hose to the adaptor cone/vacuum gauge assembly.

o. Open the suction hose’s ball valve to begin refilling the cooling system.

p. When the vacuum gauge reads zero, the system is filled.

 

NOTE: On some remote pressurized tanks, it is recommended to stop filling when the proper level is reached.

 

q. Close the suction hose’s ball valve and remove the suction hose from the adaptor cone/vacuum gauge assembly.

r. Remove the adaptor cone/vacuum gauge assembly from the radiator filler neck or reservoir tank.

s. With heater control unit in the HEAT position, operate the engine with container cap in place.

 

t. After engine has reached normal operating temperature, shut the engine off and allow it to cool. When engine is cooling down, coolant will be drawn into the radiator from the pressure container.

u. Add coolant to the recovery bottle/container as necessary. Only add coolant to the container when the engine is cold. Coolant level in a warm engine will be higher due to thermal expansion. Add necessary coolant to raise container level to the COLD MINIMUM mark after each cool down period.

v. Once the appropriate coolant level is achieved, attach the radiator cap or reservoir tank cap.

 

  1. Start and warm the engine until cooling fan comes on and check for leaks.

 

  1. Complete Proof of Corrections Form for California residents.

 

  1. Return the vehicle to the customer.
