That hose is the drain hose for the air conditioner evaporator. If it is leaking coolant, there's a good chance that your heater core is leaking, as it is in the same 'box' that the air conditioner evaporator is in. You'll need to replace the heater core.

    I was just telling michael kent, I have the same problem. he asked if anyone smelled coolant smell in the car. I don't think you would smell it in there when its leaking that much caue its all pouring out the bottom. I think especially when you have refilled your radiator so much it might smell cause you are just putting pure water in, and there is no odor to that y'know. thanks for all your help, Think I'm going to replace that on my 93 cavalier. thanks God bless-Paul Chavez

2000 Impala leaks coolant out hose in firewall

It sounds like you're looking at the heater core water lines. These connect to the heater core supply and return inlet and outlet pipes to bring hot coolant into the cabin for heat and windshield deicing.

The heater core is a mini radiator and operates on the exact same principles as the radiator does. The heater core is located behind the dash board on the passenger side. Look for a wet spot of antifreeze on the passenger side floor area - close to the firewall for an indication of a leaky heater core. If it is leaking, it will likely need to be replaced. This can be a pricey repair.

Good luck!

2000 sunfire, pontiac 2.2 eng. overheating noticed leaking from a elbow shaped hose appears to be from heater core, cuz its on the back firewall bet eng and firewall? looking for a complete diagram of...

I would start by replacing that section of hose. Depending on how much it's leaking it could be the source of the engine overheating as well. After it replaced make sure coolant level is where it's supposed to be. Hope this helps

The coolant leaks right back out from a rubber elbow hose on firewall by the heater core. should it be conected somewhere or have a clamp?

if that elbow is very low on the firewall it is a condensation drain for A/C if coolant pours out of there I believe your heater core may be leaking. Do you smell coolant in the cabin? feel free to reply, I should be around most of the day...MK

Coolant leak close to firewall from 90 degree rubber elbow. 93 pontiac 2.3 liter. It looks like there is a hose missing. Is this an overflow or am I missing a hose? If I am where does it lead?

hoses at the firewall connect the heater core inside the car to the engines coolant system.there are 2 heater hoses.the hose may have deteriorated or if the90* elbow has a clamp at the firewall end and is loose,the inlet tube of the heater core may be broken.use a flashlight for closer inspection.rapid coolant loss will result either way.

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?

You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

Pontiac Grand Am cooling system

A rubber elbow coming out of the firewall is probably the a/c evaporator drain. However, the heater core could be leaking and entering the evaporator case and coming out of that drain. Are you sure coolant is coming out of that elbow and not plain water?

Chevy cavalier 1997 2.2 coolant leak

Alright, the best way to find a leak is to fill the reservoir and get it up on ramps or a car lift would be excellent. Start the engine and find out where the leak is coming from. Most common leaks are simply just bad hoses or busted fittings. However, there could be a blown head gasket, hole in the radiator, or a bad seal on the thermostat housing.

I've even seen where a bad thermostat was causing high pressure in the water system and ended up blowing the excessive pressure and water out the overflow, even when the water was actually low. So, find the location of the leak. Use the method I told you and it will help you find the exact location. Then you can proceed on fixing the leak.

Hope this helps out! :)
