Hello: Do you know if the DT 530 has a lot of power. Deville said they had problems within the 1st year, but improved after that. Do you know the biggest or most common problem/issues with this brand of engine? any information will help. I am looking for the best mid-size engine. I have heard good and bad things about the C9. I don't know much about the Mercedes or the Cummins engines in the mid-size. What do you think is the best? Thanks for your 1st reply and your time.
They were rated up to 300hp. The dt466, which the 530 was based on, was a reliable engine. Not particularly powerful, but solid. Millions of school buses had them. They use high pressure oil to pressurize the fuel in the injectors. Since the oil has this dual purpose, it needs to be changed on time. The most common problems I've encountered is issues with this high pressure oil system. The pump sometimes leaks, the oil pressure regulator can get flaky, and the pressure sensor occasionally quits. Any decent shop can successfully diagnose and fix them, and parts are easy to get. I can't imagine the 530 is remarkably different in this regard.
Id recommend test driving any truck before buying it, if possible.
