Key Benefits
- 100% brazed aluminium core delivers more efficient heat transfer than the factory unit — built for the sustained towing and hauling demands of the early Duramax diesel.
- Natural aluminium finish and TIG-welded construction deliver durability and corrosion resistance the factory plastic-tank radiator cannot match over time.
- Magnetic Drain Plug included — captures harmful metallic debris with no additional hardware needed for a complete install.
- TIG-welded aluminium construction replaces the factory plastic-tank radiator that degrades under the sustained heat and pressure of diesel operation.
- 100% brazed aluminium core transfers thermal energy into the airstream more efficiently than the lower-density factory unit under towing and load conditions.
- Confirmed direct fit for the 2001–2005 Chevrolet/GMC trucks equipped with the 6.6L Duramax — no cutting, fabricating, or adapter work required.
- Full aluminium construction handles the thermal demands of stock and modified Duramax builds, including towing-spec and performance-tuned setups.
- Own it for life — backed by Mishimoto's Lifetime Warranty, your investment is protected long after install day.
