Why is there coolant on my windshield?
The above indicates symptoms of a bad heater core in your car. If the heater core is leaking then coolant mist blows along with the warm air by the fan. Coolant is kind of greasy and gross in this state. That being sprayed from your front vents onto the windshield is what leaves a cloudy film behind.
Why is antifreeze coming out of my vents in my car?
There are several signs of a leaky heater core: First you may notice a sweet smell from your vents. Coolant/antifreeze leaking out through the heater core means that the overall coolant level in the system will be low and the engine is in danger of overheating – which is the most common cause of mechanical breakdown.
Where does antifreeze go in a car heater?
Antifreeze runs through your heater core which usually sits somewhere behind or under your dashboard, many times on the passenger side. Heater cores are relatively fragile and it’s not unusual for them to acquire small leaks over time.
What to do if your heater is leaking antifreeze?
Heater cores are relatively fragile and it’s not unusual for them to acquire small leaks over time. To check if you have an antifreeze leak and not water, dab some up with a white cloth. If it is green, smells sweet or has a slimy feel it’s probably antifreeze.
Is it safe to run the heat with antifreeze on?
Don’t breathe the fumes very long as they are very toxic especially to small children. I would avoid running the heat for this reason. I filled up the antifreeze and it dropped maybe one-half inch. There is NO residue on the windshield or windows, and no leaking antifreeze through the floor heating vents.
Can a heater blower leak into a car?
If so, the leak is probably not the heater core and the smell is being pulled into the car by the heater blower. Either way, I’d want to have the leak found and fixed. These fumes aren’t good for you. If you have pets and they find any antifreeze puddles, it will likely be fatal for them.
