When I got tired of worrying about catastrophic coolant loss or hydro-locking the motor on long family road trips, grabbing the “Evo” EGR Cooler Delete Kit was what I used to delete that entire failure-prone assembly, bypass the cooler lines cleanly, and open up massive amounts of space on top of the block. Installing a well-engineered bypass setup completely cured my coolant loss issues, lowered intake air temperatures noticeably, and made routine maintenance like fuel filter or sensor changes infinitely easier without that bulky factory cooler blocking access. If you are preparing to tackle this job in your home garage, my main piece of advice is to buy extra hose pinch pliers beforehand and take your time vacuum-bleeding the cooling system thoroughly afterward, because trapped air pockets in these V6 diesels will cause temperature spikes on your first test drive.
