Hey all, my 2012 CRD truck is running hot and coolant is going somewhere. Its not in the oil and the coolant is also OK. I have been all over and the only thing I can see is the over flow container (the one on the LHS of the engine bay) has coolant on top of it. Apparently the radiator cap on this container is a common failure point. I have a new one ordered. Has anyone else experienced this?
