There are a lot of aftermarket parts that we install for our customer's here at Lead Foot Diesel Performance. Some of them just make things look a little nicer under the hood, but most of these aftermarket parts serve a purpose. They fix a poorly designed stock part that is prone to failure. So when it's time to replace the stock radiator on your LB7 or LLY Duramax consider upgrading to this Mishimoto MMRAD-DMAX-01 Aluminum Radiator.
Mishimoto's performance aluminum radiator for the 2001-2005 Chevrolet/GMC 6.6L Duramax is a sturdy design. With a 100% brazed aluminum core and TIG-welded to perfection, this radiator can take the abuse of any environment or terrain.
Installation does require slight trimming of the TCM cover but the process is not hard and Mishimoto has a video to walk you through installation step by step. Watch video here.
Now would be a good time to flush the coolant system and install Mishimotos silicone coolant hose kit hose kit for the ultimate in cooling performnace and reliability.
