Check the passenger side carpet and see if it is wet.. if so then your heater core is leaking into your car and you need to have it replaced. If you do not see any leaks there then check under your hood with a flash light and look for a green liquid and see if you find any leaks... usually check your hoses and under your water pump also check your radiator and coolant reservoir level. Good Luck Friend

SOURCE: antifreeze smell and smoke coming out of vents

This is definitely a heater core issue, but I might also suggest one of the many over the counter cures first before replacing it, the heater core is not a very expensive part but quite a chore to replace.

SOURCE: slow leak of water under car no antifreeze in it

No antifreeze in what? the engine, or what's leaking on the ground? if leak is water, under the vehicle on the passenger side between the front of the door and behind the front wheel, it is coming from the air conditioner drain. It is supposed to do that.
If what's on the ground is antifreeze, check the heater hoses and control valve.

SOURCE: smell antifreeze inside when car is running

Check the floor mats for moisture; you may have a bad heater core. You can also get fumes from an under-hood leak if serious enough, check the level in your coolant overflow to make sure you aren't losing a lot of coolant.
BTW, replacing the heater core can be a real hassle; they are normally installed before the dashboard and can be nearly inaccessible.

Smells like antifreeze


If it smells like antifreeze inside the car, you're heater core is probably leaking. If the smell is outside the car, could be mulitple things i.e. radiator, hoses, waterpump, or thermostat.

Smell antifreeze inside car


If you don't see any antifreeze leaking in the engine compartment (especially around the radiator) you could have a leaking heater core. Does the smell go away if you turn off your heater for a while? If so, that's likely where your leak is.

The inside front window is getting clouded and there's a antifreeze smell


Sounds like the heater core is leaking. Locate where it is and see if antifreeze is leaking out the bottom.

Smell of antifreeze in the car why is that?


If it's not leaking externally I would check the heater core. Feel the carpet under the passenger's side of the dash. Wet carpet = heater core.

How do u bleed the hoses from the radiator u can smell the antifreeze in the car need to know if it may be a hoses or something less


If you smell antifreeze inside the car then you probably have a bad heater core causing the coolant to leak inside you vehicle and giving you the antifreeze smell which will make you sick. If you windshield is all foggy and hard to clear and the right passenger floorboard is wet then your heater core is leaking.

You can drain the coolant out of your car by taking off the lower radiator hose. This will get most of the coolant out of your car. If you have a hose leaking under the hood you may smell coolant inside the car, but it shouldnt be too bad, if you have a leaking hose however it should be pretty obvious and your car may even be overheating.

Will not heat. I smell antifreeze inside. Thermostats been changed, new antifreeze added.


If you smell antifreeze in the cabin then it could be a hose loose or the heater core has a leak/pressure leak - in which case get it looked at ASAP because it could lead to overheating of the engine.

Check the hoses going to the heater core and make sure they are not cracked or disfigured and are on tight. Any moisture near or on the core (and/or corresponding corrosion) is an indication the hoses are ot doing there job or the core is leaking.

BTW, If you are loosing coolant (due to a faulty heater core) it could "explode" (relax, you are basically safe on the other side of the dash-board), but the result could be a destroyed heater core and a very expensive repair bill - I know because its happened to me!

When i run my 1996 dodge ram 1500 it smells like antifreeze. i had the head changed but it smells like antifreeze. what could be the problem?


check the coolant level to see if it has dropped.Then look under the engine,for any leaks.Look for pools of coolant on top of the engine,or run down on the sides of the engine.Then look for radiator hoses,ans heater hoses that are leaking.If you are loosing antifreeze ,and you are sure the coolant is going somewhere,you may sill have a head,or head gasket,that are bad.If it has not been long before the head change,then the antifreeze may be still present in the exhaust,or on the engine,so you may have to wait a little longer for smell to disapate.Cleaning the engine can help.

Antifreeze smell


If u smell the antifreeze inside the car, the heater core needs to be replaced most likely. It is leaking inside, and will get worse, to the point of 'fogging up' the windows inside.
