There are numerous possibilities. You really need to have the cooling system pressurized to determine what is leaking.
You normally smell the antifreeze so open the hood and look for a leak before you see it big time running out from under your car.
antifreeze smell inside car means that there is antifreeze leak somewhere. first check for wet spots under car when parked after running.if anti freeze is leaking from engine it will pool on the ground next check to see if heater core is leaking. that is usually the problem. if heater core is leaking, replace it
Changing ac components under the hood should not cause a chemical smell. If the smell changes by changing the air settings from recirculate to fresh, then there may be some chemicals on the outside of the parts. It is also possible that you damaged a part of the heater core system and the smell is antifreeze.
If you smell antifreeze in the passenger compartment of your car your heater core is probably leaking. It's under the dash somewhere ( depends on the make and model ). Another symptom of a leaking heater core is moisture build up on the inside of the windshield when you run your defroster.
if you can smell antifreeze, you have an antifreeze leak somewhere. you need to clean engine then look for coolant . it will generally pool on ground under vehicle unless it is leaking onto engine and burning off. note that the coolant will run so you may have to trace back to the actual leak. check all coolant fittings, such as hoses and check area round water pump.
I hasd a similar problem with a 1990 Camaro. My carpet was wet from a leaking heater core. Smell the carpet where it is wet. Does it smell like antifreeze or is it the color of antifreeze? If so nyou have a bad or leaking heater core. Good Luck
you got an antifreeze leak
Check for a line leak to your heater core or a leak in the heater core it self. Usually it is under the dash on passinger side.
If there is a small drip of antifreeze under the car behind the right front tire, this could be from the evaporation hose. Antifreeze may drip after the car has been run with the air conditioning on. If the air conditioning was not on just previous to noticing the antifreeze, it would be a good idea to check all of the hoses for leaks.
On the Ford Windstar 2001 model, it is under the hood, next to the battery.
Check Antifreeze level..make sure there are no leaks under the vehicle.
Yes it can, as long as the engine is running. Be careful when taking the radiator cap off thou, cause its under pressure.
