Replace the Engine Oil Cooler in your 2001-2016 GM 6.6L Duramax with the XDP Duramax Engine Oil Cooler XD411. The XD411 is a direct-fit replacement for the leaking or contaminated oil cooler on your Duramax engine. While the factory oil cooler is not prone to failure, it is a crucial engine component that should be replaced after many years of operation.
Metal particles and debris that are not captured by the oil filter will circulate through the engine and ultimately collect in the engine oil cooler. The factory Duramax engine oil cooler features a stack plate design which makes it almost impossible to clean. Replacing the oil cooler is a good idea during any engine rebuild, or tear-down after a catastrophic failure. Each oil cooler features a high-quality construction and is designed for a direct-fit replacement
