Bulletproof Oil Cooler is a ton of money.īulletproof Diesel insists on their oil cooler. From our years of experience, here’s our recommendation: Get the Bulletproof EGR cooler and Ford oil cooler. We’ve owned and sold almost 1000 6.0 Ford diesels. (So we can pick a $300 water pump over $3500 head studs and it’s “Bulletproofed” just the same?) We recommend the Bulletproof Diesel Stage 1 - new Ford oil cooler and Bulletproof EGR cooler.īut in our opinion, that definition of Bulletproofed feels more like marketing than solid advice. (And because of the confusion, we stay away from using “Bulletproof” or “Bulletproofed” in our marketing.)īulletproof Diesel’s latest definition to qualify as a Bulletproofed 6.0 is to replace 4 out of 5 of the following… The internet forum intelligencia claims “Bulletproof” definitions, but they are all varied. Internet forums gave “Bulletproof” a life of its own. The cylinder heads float and the head gasket is destroyed. The overheating EGR breaks apart and dumps coolant into the intake.įor the final straw, cylinder head pressures raise trying to combust water. The EGR cooler chills hot exhaust gases, but when water doesn’t reach the cooler from clogged upstream channels, it quickly overheats. That oil cooler blockage starves the EGR cooler. As particulates built up from the sand-casted parts, coolant passages block in the oil cooler. But small channels also clog with debris. The smaller the channels, the more cooling capacity. Ford built the factory oil cooler with very small channels.

The “6.0Ls are junk” myth began.īut when Ford engineers took a step back, they realized the head gaskets were simply the breaking point in a chain of failures that started back with the oil cooler. Ford dealerships replaced the head gaskets only to have the engines melt down again. Many early customers suffered blown head gaskets and sought Ford’s help under warranty. The 6.0L Backstory - Why We Need Bulletproof Diesel, (or what went wrong at Ford)Ģ003-2007 Ford 6.0L diesel engines have a bad reputation.

They’ve since added aftermarket oil coolers, fuel injection control modules (FICMs), water pumps, and other 6.0 powerstroke accessories.īut quickly Bulletproof Diesel lost control of their branding and “Bulletproof” generically refers to an upgraded 6.0 engine kit, often consisting of a built motor. Bulletproof Diesel became famous making aftermarket EGR (Exhaust Gas Recirculation) coolers for Powerstroke 6.0L Diesels. Bulletproof originates from Bulletproof Diesel, a parts and service shop in Mesa, Arizona.
