WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Caution must be observed when removing the EGR cooler core as to avoid sealing flange scratches or damage to the sealing surfaces may occur.
NOTE:

- Remove the 4 bolts, 2 stud bolts and the EGR cooler end tank.
- Discard the EGR cooler end tank gasket.
- Remove the 10 bolts and the EGR valve and bypass assembly.
- Using 2 equal lengths of wood or 2 equal length hammer handles, insert them into the opening at the EGR cooler end tank until they touch the EGR cooler core.
-
NOTE: A snug fit of the wood will keep the wood from falling out of the EGR cooler and will aid in the removal of the EGR cooler core.NOTE: The EGR cooler O-ring seals are very robust and will hold the cooler core very tight in the EGR cooler housing.
Holding the EGR cooler housing, strike the EGR cooler housing down on the wood forcing the EGR cooler core out of the housing.
- Discard the EGR cooler core gasket.
- Remove the 4 EGR cooler core insulators.
- Remove and discard the 2 EGR cooler O-ring seals and clean O-ring seal seat on the EGR cooler housing.

NOTE: Gaskets are sensitive to debris and surface defects, sealing surfaces must be thoroughly cleaned before new gaskets are installed.NOTE: Scratches as shown may lead to leaks.
Inspect all cooler sealing surfaces for defects that may lead to a leak path. If defects are found, replace the components as required.
