Cummins 3002138 Turbocharger Heat Blanket

This turbocharger heat blanket, OEM part number 3002138, functions as a thermal insulation cover for the turbine housing on Cummins NT855 series diesel engines. It reduces under-hood temperatures, protects surrounding components from radiant heat, and improves turbocharger efficiency by maintaining exhaust gas temperature. Constructed from high-temperature ceramic fiber insulation encapsulated in a stainless steel wire mesh or silicone-coated fabric jacket, it is engineered to withstand continuous exposure to extreme exhaust temperatures. The blanket is secured via integrated spring latches or wire hooks for reliable retention under vibration. It serves as a direct replacement for Cummins part numbers 3003697, 4931619, and 3024162.
