2014 Ram 5.7 hemi issue.

First thing I do is actually one of 2 things. When a noise comes from front of engine I drop the accessory drive belt and turn things by hand. If the noise seems to come from rear of engine I'll use a long tube funnel like a transmission funnel as stethoscope to narrow down the source area. This can work with accessories running under drive belt pressure but isn't exactly safe.
At your stated age and milage, if it hasn't already got a new water pump, its due, statistically speaking of course.
