The GM 12732979 Engine Oil Cooler Assembly will replace the contaminated oil cooler in your GM 6.6L Duramax LML. The oil cooler helps maintain proper engine oil temperatures and should be replaced if coolant or metal particulates get into the motor oil. Cleaning the oil cooler is nearly impossible as the stack plate design doesn't allow easy access to the passages inside the cooler. This genuine GM Engine Oil Cooler Assembly is engineered, developed, and tested to stringent standards, and is backed by General Motors.
Features:
