If Your 2015 Ram 1500 is leaking coolant, You're going to want to get it diagnosed and fixed as quickly as possible. Luckily, there are a few places where You should start. It may seem obvious, but You should begin searching where You see the puddle forming. If there's no puddle, look around the components under the hood where You're seeing antifreeze; it's very possible that You've got a split or otherwise degraded coolant line. Alternatively, the '15 1500s are known for their water pump issues; You may want to take a look at the seal around this, as it may be the cause if the location is approximate.
