Bullet Proof Diesel Duramax EGR Coolers

Taking EGR cooler technology a step further, Bullet Proof Diesel has engineered a patented, self-accommodating ‘H-Core’ design that allows for the natural expansion and contraction of cooling tubes inside the EGR cooler.

Bullet Proof Diesel, a leader in diesel reliability products, has released a new line of EGR coolers featuring the patented H-Core technology, which was developed to resist the common causes of EGR cooler failure. Immediately available, the EGR coolers have been engineered for 6.6L Duramax LML applications, which are found in 2011-2016 Chevy and GMC pickups.

Taking EGR cooler technology a step further, Bullet Proof Diesel has engineered a patented, self-accommodating ‘H-Core’ design that allows for the natural expansion and contraction of cooling tubes inside the EGR cooler. This limits structural failure, which can occur at the end of the tubes, rupturing the EGR cooler, rendering it useless and leading to possible engine component damage. The H-Core construction also increases the surface area of the coolant tubes within the EGR coolers, making them more effective heat exchangers than other tubed designs.

A more forgiving EGR cooler design is integral to the durability of the component. During the life of an engine, a ‘thermal event’ – that is, an occurrence in which sufficient coolant flow is prevented from reaching the EGR cooler – will cause a temperature spike within the unit that often leads to component failure. This leads to truck downtime, additional repair costs, and legal issues, as keeping the EGR cooler operational is a necessary contingent for public road-use legality in all 50 states.

The BulletProof 6.6L Duramax LML EGR coolers join the other Duramax offerings from Bullet Proof Diesel, including EGR coolers for the LBZ, LLY, LMM, Top Kick, C/K Series, and G-Series engines. This latest addition means that Bullet Proof Diesel’s line of EGR coolers are available for trucks produced by all three of the domestic pickup manufacturers (Ford, GM, Fiat/Chrysler). Additionally, Bullet Proof Diesel has expanded its line of commercial-duty EGR coolers for Class 5 to Class 8 trucks.
