Bullet Proof Diesel Duramax LML EGR Coolers

August 2020 Products DT Staff


Bullet Proof Diesel 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. The EGR coolers have been engineered for 6.6L Duramax LML applications, which are found in 2011-2016 Chevy and GMC pickups.

With a track record of more than a decade, Bullet Proof Diesel revolutionized the light truck diesel segment with the advent of the BulletProof EGR cooler, which greatly reduced the failure rate of the component within specific diesel engines. Taking the 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 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, and LMM engines. This latest addition means that Bullet Proof Diesel’s line of EGR coolers are available for all applicable trucks produced by all the big three American pickup manufacturers (Ford, GM, and Fiat/Chrysler).
