Yes it's the heater core, It's a complicated diy job and unless you are an experienced mechanic you are going to need a good workshop manual for the job.

Best of luck.

SOURCE: 01 mercury villager smell antifreeze inside, no heat.

If it is just an odor I think I would try some cooling sytem sealant. Usually costs about $3 to $5.00. With the engine running and hot with heater on, open the container and pour into the overflow and let engine run for another 15 minutes or so. DO NOT REMOVE THE RADIATOR CAP; YOU MAY GET SCALDED!!!!!!! Do not open the sealant container before you are ready to use it, it hardens quickly.

SOURCE: How do I replace my heater core?

It only takes about thirty minutes if you get lucky. Take the glovebox door and flip it down towards floor. There will be a cover with maybe three screws in it ,remove. It will help if you have a flex cable type extension for your hex nut driver as the screws are sideways. You will see the heater core and it has a ******** the end of it with two screws so remove them. Un do hoses, to me this was harder than putting the core in and out due to the special sqeeze clamps. ps. they make a tool for these clamps. remove heater core and dry area. be careful with new heater core as not to damage it putting it back in. The new core should come with some foam strips and instructions.. Any more questions on this car feel free to ask I have had mine since 2000 and it has 296,000+ miles on it.

SOURCE: coolant smell inside cab when you turn on car/heat

Likely you are in the beginning stage of a heater core leak. at this point, you may be able to temporarily solve the problem by using a good system sealer (I'm partial to the kind that comes as a silver powder) Since we don't actually know the condition of the core, temporary may mean a week or several years, but replacement is expensive and time consuming so I'd definitely give it a try.

Ford f-150 that has smoke coming inside the vents when you drive it.what would cause this? 4.5 v-8


You trucks heater core is leaking inside the dash heating vents, the air blower motor blows through the heater core and then you smell the leaking coolant in the form of a sickly sweet vapor. You will need to replace the header core, this is a fairly big job and in most cases best left to a professional.

Is the heater core slowly leaking antifreeze? Do you smell any sweet smelling antifreeze smell associated with a leak?

Or, do you drive through a lot of construction zones that blow contaminated air onto the windshield?

Why does heater smell sweet


Hi yu heater smelling sweet is not a good thing. There is an engine coolant leak probably in the heater core and the smell your noticing is aspirated ainti-freeze. Check your engine coolant. It should be slowly lowering. The only fix is to have the heater core replaced. You can for the moment bypass the heater core by looing the hoses together with a nipple on the engine side of the firewall but you will have no heat or heated defrosting abilities until you replace the heater core.

Thanks for choosing FixYa.

2000 jeep cherokee does not heat or defrost fan


the oily substance you talk about is antifreeze, your heater core is damaged and leaking in the form of mist and going to your windshield you must replace your heater core in the dash generally behind the glove box.

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 !

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.
