Your vehicles heater core has developed a hole and or leak, the heater core is the unit that looks like a small radiator that transfers heat out of the coolant and into the interior of your vehicle in order to keep you nice and toasty warm when you use your heater, it is tucked up under the dash behind the glove compartment, so when it is leaking, this will leak coolant into the interior of your vehicle.
It is most fesable to replace the heater core, rather than to repair it.
GOOD LUCK !

SOURCE: coolant leaking under dash in

This leak is located on passeneger side most likly.This is where your heater core is located.Over time heater cores can go bad, they are like a miniture radiator.If coolant hasent been changed regularly,the heater core can rot out causing leak.If you are luckey it could be one of the hoses going to heater core,but id hate to say this is rare.

No heat in 1999 sunfire


This can be a few things, for starters most common in my experience is when you have air bubbles in the coolant system (Mostly when its been recently drained or flushed) You will have no heat. Also, if your heater core has failed (in most cases water will leak from under your dash) you will loose heat and your vehicle will most likely overheat. Last but certainly not least, a failing head gasket could cause combustion to leak into your coolant system causing air bubbles which could make your heater not work which could also cause overheating in further along failing head gaskets. Things to check would be a leaking heater core under the dash, overheating, check engine lights and bleeding the coolant system.

Coolant leak under dash


Heater core leaking. It will cause low coolent levels, moisture on the glass that won't go away. Green liquid leaking from under dash, wet floorboards. Hissing sounds when car is turned off coming from behind the dash. You may have some or all of the above symptoms.

Leak under dashboard


The only fluids under the dash are coolant that circulates through the heater core, or if you have a manual transmission a failed clutch master cylinder can leak brake fluid under the dash right where clutch pedal is located. If the heater core is leaking, it usually shows up on the passenger side. If it is just plain water, you need to check how rain water could be getting in past the firewall and under the dash.

Smells like radiator fluid but its not running hot?


If you smell it in the cabin you probably have a leak in the heater core which is up under the dash. Look under the center portion of the dash on both sides and try pulling the carpet back in that area. Chances are you will find evidence of a small leak. Check all hoses for tightness that run along the firewall in the engine compartment as well.

I have a 2001 Chevy Blazer. While driving it and running the airconditioner I can smell coolant. I'm having to add coolant regularly, it's obviously leaking somewhere, but I don't see any on the ground or...


Maybe the coolant is leaking into a cylinder, slowly and also leaking out of the head gasket to the atmosphere when running under the increased load of the a/c.

If having to add coolant regularly, you're right, it must be leaking somewhere. It could be leaking out onto a hot part of the exhaust so look around there.

Water leaks from under dash on the passenger and driver side and water leaks from the visors on both sides 1997 saturn s series


If you have a sunroof then the problem is most likely a drainage problem with the sun roof. The drains are blocked and the water is running down into the car.

The under the dash thing is the only thing that worries me. That is usually the location where the heater core will leak to. Are you sure it is water and not coolant? Coolant gives off a sweet smell and when it's hot you know cause it stinks.

But my money is on a sunroof leak and drainage problem if you indeed have a sunroof.

If the coolant is in the cab they did not cause the problem changing the manifold gasket. It sounds like the heater core has failed, which is under the dash.
