I could be either one,but if you smell antifreeze, than you should be able to see a leak while the engine is at running temp. Fell the floor for wetness for heater core, Check under the hood for wetness for hose or radiator. Also, if your windshield fogs up, it is most likely the heater core. You can also pressure test the cooling system to verify where the leak is.

Loss of coolent

First I would look at all the hoses for pinhole leaks. The test the water pump by trying to move the radiator fan back and forth(on a longitudinal engine, not transverse). Turn on the engine and see if there is any coolant leaking from the front of the coolant pump. If so, the coolant pump is going bad. Otherwise, can you smell the sweet smell of coolant in the cab? If so, you probably have a leaking heater-core,

I have a water leak and it is not the water pump

can you see where the leak is coming from? have you checked your oil to see if it is milky grey? if it is you probley have a blown head gasket and should'nt drive it. hoses could be worn and old, radiator might be leaking, heater core hoses are bad if the leak is by the firewall? can you smell something sweet when you turn on the blower fan? again the heater core. some places to start, good luck

Leaking coolant

Is the coolant clean that leaks out? Have you put a newspaper under the car to try and isolate the leaks location by the drip stains? Likely spots are the engine water pump and hose connection points at have worked loose. If the leak seems to come from the rear of the engine it may be a leaking heater core, in that case you should have a kind of sweet smell (the smell of vaporized coolant) in the cabin when the heater is on.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on

Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

You have a heater core leaking.The whole dash has to come out to replace the heater core.This is antifreeze you are smelling.

Wasn't no problem with untel i replace my water pump. as i finish the water pump job i turn the truck on and feel it up with antifreez and at same time i turn the heat on and smell of entifreez comes out...

You have an antifreeze leak. Probably in the heater core (a small radiator inside of the dashboard that heats the air as it passes through). When the engine is running do you see any steam around the engine? Or smell the sweet antifreeze smell around the engine? If not then it is probably the heater core instead of a hose or somewhere on the engine. Does this truck have the option to switch the heater to recirculate he air inside the cab instead of drawing in outside air? If it does then you can set it to recirculate the air inside and if it still has the smell then its definitely the heater core. Often with a leaking heater core the passenger side floor and firewall area will get wet, but not always.

''sweet smelling'' steam and overheating light is on.

your heater core or heater core hoses are bad and have sprung a leak the sweet smell is from antifreeze this is not a do it yourself-er if you are squeamish about tackling a big job sometimes they can be a real pain to get, like the built the entire car around it.

Smell antifreeze, no leaks, gurgleing behind drivers side dash.

there is air in system causing gurgling/set heater to defrost and check for sweet smell. do while stopped if core is leaking windshield will fog up and be hard to clear.
