1991 chevy c1500 heater core

I have a 1991 chevy c1500. I first started to notice that my windows started fogging up and then I had a smell of coolant inside of the cab. Then 2 days later, it started dripping inside of the cab on the passenger side. Would I have to replace the heater core or would it be a different problem

SOURCE: antifreeze smell and smoke coming out of vents

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

SOURCE: Heater Core Leaking

you could quick fix! but you will have no heat, 1st under the hood, look at the back of motor, follow all you're radiator hoses, take two hoses off the heater core stick a pipe that is big enough then clamp the pipe down. to both sides of hoses to the pipe you will eventually have to replace heater core!!

SOURCE: strong coolant odor in cab of car Chevy Tahoe 2002

have your freeze plug checked. I had the same problem and the culprit was freeze plug. heve it pressure checked by your mechanic. freezer plug is so cheap. Around $5.00. the only thing is it's not easy to replace. they have to remove the manifold to gain access on it.

2005 chevy equinox window fogs up and a strong smell of antifreeze but my floor is not wet


It sounds like the heater core is leaking. You may not see a wet carpet. There is a drain tube that allows condensation to be directed outside the vehicle. You may notice that the coolant is draining onto the ground instead. Check the heater core first then the two heater hoses. A coolant pressure tester will help you find the source. Let me know how you make out, Good luck.

While driving my 95 explorer i noticed the heater wasnt getting hot its luke warm and when i turn on the defroster i start to smell anti freeze and all of the windows fog up


no heat is probably low coolant or bad thermostat,although you have fog and smell ! the heating and cooling systems are closed systems the only way the windows fog is the coolant is hot and steams inside the car due to some leak inside the heater core box. as well as the smell being present. Now it is possible that a little leak has occured where the coolant supply or return line connects to the heater core and is running into the car which is running onto the core and creating steam and smell. hopefully it is a easy clamp tighten fix for you.

The only part that has coolant running through it under the dash, is the heater core, when it goes bad, you will smell coolant and the window will fog up, leaking heater core, replace it be for it start's to over heat your engine and cause more problem's in the long run.

Window fogs up after driving for awile. Just


The mildew smell you refer to could be anti-freeze. When a heater core starts leaking it may allow anti-freeze (which circulates through it for heat) to be blown through the ducts onto the windshield in defrost mode. The repair is to have the heater core replaced. It may wait for the thermostat to open and allow the coolant to circulate before you notice it. Occasionally the carpet on the passenger side may be wet from leakage.

Windows fog up,small anti-freeze smell


The early sign of a heater core leak is the smell of coolant, the reason is that only vapor is leaking now, it will gradually get worse in most cases and coolant will start comming out the heater box condensation drain.
