Antifreeze/coolant leaking from under passenger side dash

I've got an antifreeze/coolant leak on the passenger side of my 1993 Chevy Blazer S-10. A friend of my suggested it might be the heating core. Looking for any tips on fixing this problem myself.

If it's your heater core, unless you're a mechanic you probably should get professional help. The heater core is located on the firewall and many parts need to be replaced to get to it. Do you see water on the floor inside the vehicle, Many times a heater core will leak inside.

    sorry I wasn't specific when I said water on the floor, I meant liquid and since you do have antifreeze then it is most definetly the heater core. I would not suggest you try this yourself. It's a big job.

My 2009 ford focus air conditioning smells like coolant


It sounds like you may have a slight heater core leak and when you turn on your air, it's simply "stirring up" the smell. I've never seen this issue ina Focus but i have in a '97 Bonneville. The heater core is located behind the dash and requires complete dash removal to locate. It's a rough job to tackle alone. A lot of shops can run a "leak test" where they run a pink dye through your A/C system and see if it leaks anywhere. You may simply have a dry-rotted hose or bad seal. But my bet is the heater core, as thats the only place antifreeze enters the interior of a vehicle. Try smelling up under the dash on the passenger side and see if the smell exists there. If so, it's a heater core leak. Hope this helped!

2004 chevy trailblazer leak n antifreeze from behind fan


the fan you are referring to is inside the trailblazer on the passenger side behind dash near floor wall? If this is the case it is the heater core and needs to be replaced by a professional. If is is under the hood in the engine compartment it is the water pump in need of replacement? thanks good luck on the heater core..

Leaking fluid under dash in car on passenger side also has load thumping noise when steering car into turns on the right side


You dont mention the year, make or model of your vehicle but generally a fluid leak on the passenger side interior is a coolant leak possibly from a defective heater core.Does it have a sort of sweet smell like antifreeze ? Also check under the hood to see if your engine coolant is low.

I have coolant steam inside my car coming from my heater - 98 chevy blazer


Hello
Your going to need a heater core,this is located in the heater fan box under the dashboard.
Possibly may be found mounted to the firewall under the hood.

Let it cool down before attempting any repairs.Another possibility is a broken hose at the heater core.

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 below dash on passenger side.


if it is pure water and not antifreeze then i would say the drain is blocked. check under your hood on the firewall around heat/ac for your drain tube

I have a problem with a coolant leak on my 2000 Chevy Blazer. It's coming from the left side of the engine, about mid to lower engine. I can't see where the leak is coming from due to the leak bouncing off...


you could have a expansion plug on the left side of the engine block leaking antifreeze,if your blazer is a 4x4 remove the skid plate under the front bumper and you should be able to see where its leaking from,a water pump will be a steady drip while its running usually but a expansion plug will pour out very fast
