Yeah, when you have not only the cooling of the motor, but water cooling of the turbo and water cooling of EGR on these modern diesels, it really puts a strain on things. This is why radiator requirements doubled on heavy commercial trucks. The emissions junk really takes away from the glamour of diesel. Even in many medium duty trucks that traditionally had diesels, they are scaling back and putting larger gasoline engines in them. You can thank your government who cares for you. Sarcasm intended.
Freedom is not the ability to do what you want, but the ability to do what you ought.
