Exhaust Gas Recirculation (EGR) Cooler - 6.7L Diesel: Installation

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: Make sure the EP sensor tube is aligned on the stud bolt on the back of the EGR cooler.

Using 2 new EGR cooler assembly gaskets, install the EGR cooler assembly on the alignment pins and install the 7 bolts.
- Tighten to 10 Nm (89 lb-in) in sequence shown below.
