Antifreeze is used to heat the cab of your vehicle. When you turn on your heat in your cab, it opens up a valve that allows the hot antifreeze to flow from the radiator into the heater core. If there is a leak in the rubber tubes that flow into the heater core, or if the heatercore is damaged, you will smell the antifreeze in the cab of the vehicle. You may need new hoses to the heater core and/or a new heater core.
the rubber elbow is a drain for the heater and ac box, it should only have clear water coming out of is on a hot day with the a/c cranked up. and antifreeze indicates a bad heater core.

Burning antifreeze has a rubber like smell. Some people think it smells sweet with a tint of rubber smell mixed into it.
dis connect the rubber hose that goes from the radiator to the plastic reservoir. It is connected with a clamp and a pair of pliers will do it. Then, un-srew the bolt that holds the reservoir to the metal frame-work. Replace with new bottle and reverse the procedure Should take ten to 20 minutes. It was easy.
Your intake is probably cracked. I had the same problem as well as others on a 98 LeSabre. I could smell the antifreeze and the fluid leaked down.
Take off the reservoir & flush it out with hot water to get the oil out. If you drive it it can go through the cooling system and it may distort rubber seals etc. If it's a very minor amount it might not be an issue but flush it to be safe.
That is the drain from the heater core housing. It will only leak coolant from there if the heater core starts leaking. This is to help prevent coolant from ruining your carpet/interior. You have a bad heater core. Time to replace it. Good luck!

chances are that your heater core is leaking and needs to be replaced The coolant is draining from the heater case. This is what houses the heater core and prevents the antifreeze from flooding into the car. That elbow is the drain hose for the heater case, which means your heater core is leaking and needs too be replaced. Good luck.
