I have a 2013 1500 5.7L with 140000 miles having a few issues with coolant/heater and I think they are related. First noticed that when heat was on that cold air was blowing on driver side. Hot on passenger side. Soon after started smelling hint of coolant out the vents and outside of vehicle after heating up. No visible leaks. Now have visible leak from front of engine and can't determine if it is from the hose or from water pump. Do I replace it all working my way through hoses, water pump, heater core until it I find? Has to be better way. Is not overheating at this time.
