BD Diesel EGR Cooler - Cummins ISX 2007-2009 1090301

Replacement Heavy Duty EGR Coolers for mid-line & heavy duty applications have TIG welded 304L stainless walled tubes to replace the OEM inner cores that have been known to fail. The failure of the OEM units has caused coolant to leak into the cylinders creating a hyrdolock condition which will damage the head gaskets and possibly the heads themselves.
