As stated in the head line. 2015 ram eco diesel. Coolant leak top back side of motor. I cannot see where it is coming from. The manifold and a fitting were replaced at 148000 miles. Since then I’ve had no coolant loss until this recent rupture. I have good parts changing and mechanical abilities. I only have basic tools and Jack stands no lift. Any help or insight on what to take off to see better would be appreciated
