Re: Where is the heater core located on the 2002 Volvo...
There may be a clogg in the drain for your air condition. Or the drain for the water coming off of the windshield (on the bottom where the wiper blades are, may be clogged with leaves or debris. To check take a hose or alot of water and pour on windshield then look to see if it drips inside on the driver floor. To check if its an Ac drain leak turn AC on and run for a while and check to see if the mat is wet or water is dripping on floor mat. Good Luck

heater core is located on the front passenger side next to your ac evaporator assembly, your heater unit uses engine coolant water as a heater , the reason why you smell anti freeze because your core has a leak.
you can disassemble the unit if you have the right tool and by removing the front glove box and console panel to expose and give way to check that unit, it normally fastened by screws and a few bolts and nuts.
There is a leakinside the passenger compartment in the heater core housing.
Could be the heater core or a hose connection to the core.
The coolant is exiting to the ground outside through the water drain tube attached to the bottom of the heater housing (normally, this drain tube will drain water that was condensed by the A/C).
A quick repair, if you don't need the heater for now:
Under the hood, re-route the heater hoses by connecting each hose end to each other with a 5/8 inch diameter hose connector (like splicing a garden hose).
Eventually, the heater core will need to be replaced.
Sounds like a leaking heater core or faulty hose connections.
Sniff a tissue after blotting some of the wetness or; it may not sound appetizing, but to check if it is coolant + water, take a clean cloth, blot the wet spot and touch the other side of the cloth to your tongue.
Coolant doesn't have a strong odor unless it is hot but it lends a sweetness to the coolant that is easy to detect.
That is why one shouldn't dump coolant on the ground since domestic animals will lap it up.
