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 new EGR coolers have been engineered for 6.6L Duramax LML applications, which are found in 2011-2016 Chevy and GMC pickups. With its original BulletProof EGR cooler, 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.
During the life of an engine, a ‘thermal event’ - 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.
According to the company, 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. Bullet Proof Diesel also says that 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.
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.
