Default Coolant leak

Well I have been getting a nice syrupy smell when I put my defrosters on and I realized it must be a coolant leak. My only problem is I don't know where its leaking from. Any ideas on what to do?

u need to get a coolant pressure tester and pump the pressure up to the pressure ur cooling system is at max and it will simulate the pressure to without the motor running. then u will need to search for the leak!

I know there isn't a leak in the truck, atleast yet. So when I pump the pressure in, is the leak just going show from that cause of all the pressue? Sorry I am dumb to this.. If its the heatcore, how hard is it to replace and cost?

yes basically it is so u can look for the leak without having the motor running (dangerous looking for a leak near a water pump with the mech. fan running) are you getting any fluids in the floorboard of the cab?

Nope no fluids on the inside. My sisters bf actually told me it was a leak cause he is a mechanic and he smelt it when I was bringing them to the airport. Before he left he checked under the dash and felt nothing and saw nothing of a leak on the inside, and I haven't either.

Looks like the dash has to come out to get to that heater core!

The heater core is incased in plastic covers so you may not see leaks on the carpet.

Yeah, they don't usually just dump the coolant into the passenger floorboard like they did in the "old days", but they do usually have a vent somewhere to dump the leaking coolant. If the vent outlet isn't readily visible somewhere, maybe stop by a Dodge dealer and have a mechanic tell you where the vent line exits so that you can see if any coolant residue is showing up there.
