My Duramax is leaking antifreeze
Came out the other morning and while loading the truck for a trip to Seattle noticed something leaking from the truck. Got under the truck and looked up to see where the leak was coming from. With a light I could see antifreeze was leaking from somewhere up above the oil filter housing. I think it may be the blue hose that comes off the turbo but not sure at this time because I have not had time to check. The question I have if it is not the blue hose from the turbo, Where else should I look ?

The blue hose from the turbo is the air hose to the intercooler. The notorious coolant leak near the turbo is the small hose that goes to the water outlet pipe. It sounds like your leak is probably where the oil cooler goes into the side of the block just above the oil filter assembly.
