I have put 2 gallons of 50/50 coolant anit freeze in in that past 5 days. IT has used all but, i would say 2 quarts of it. I do not know what is going on I thought maybe head gasket ouch just replaced my VP. I am also smelling a sweet aromatic smell in my cab which I have been told is antifreeze or something. I do not know what is going on please any help would be appriciated. Thank you all so much. Ben

That smell is the anti freeze , it sounds like your heater core has sprung a leak. FWIW , i am not sure , but i think that breathing in the fumes from anti freeze for too long can be bad for you , but i could be wrong too.

Sounds like your heater core may be leaking to some degree. I don't know if that's your entire problem though. If 2 gallons leaked inside your cab, I think you'd know about it. It's possible that the core is leaking into the HVAC housing, then draining out through the evaporator drain tube. The drain tube exits through the firewall, engine side, just under the A/C accumulator. See if it's wet with coolant. Heater core leaks are rare on our trucks, but not unheard of.

The most common leak spots are water pump and head gasket, right at the right front corner.

I had a freeze plug on the back side of the block (next to the firewall) with a pin hole sized leak a few years ago. It caused a sweet smell in the cab like you mention. If your heater core is not the problem, you may want to check this. It was kind of tough to find, though. Had to use a small mirror to locate the exact location of the leak.

Check your oil just to make sure that you don't have any coolant in the oil. Smell the exhaust to see if you can smell the same smell you do inside the cab, too.

The smell suggests anti- freeze. Is the floor carpet moist or wet at all? Lift the carpet/mat and look for moisture.
Is there any stronger smell when the heater is on? Do the windows get moisture on them?
I've had this in two non-Dodge vehicles over the years. Both were a heater core leak.

Good luck!

I just HOPE it's the heater core, and not the block. If your AC drain tube is clear, as it should be, you won't have a leak inside the truck as it all drains out on the ground.
