Today I noticed a large amount of water draining from under my 02', after going to work and idleing 15 mins before going in.

The water is draining from the elbow shaped hose that comes out of the firewall. (next to the A/C lines) (passenger side)

I don't believe my car is running hot? Just a shade over 200. Heat works, A/C works. Coolant level is fine.

I don't know a whole lot about cars, and I've searched the forums, but am still unsure of what my problem is.

are you sure its not the condensation from the ac lines? bc when its hot out you get a lot of water under the car from the heat

Thanks for the reply.

I had my heat on this morning, only ran the A/C [after] I noticed. (just to see if there was a difference) But it's not moisture dripping off the metallic lines, it comes out of that rubber elbow hose. Like a outdoor house spicket.

That's normal. That elbow is a drain for the Evaporator case. As it happens with all A/C systems, when you cool the air going through the system, moisture gathers on the cooling element and needs a place to go. "erefore it goes through the elbow and outside the car.

Thanks to all of you. It is much appreciated.

I did read that thread, and thats whats making me think it's the water pump about to go bad. (I have no idea where it is, or what it looks like) But threads say a pre-cursor is "water leaks out of the hose".

And would that hose (the passenger side/elbow shaped/firewall one) drain water if I heated my car? I never cooled anything.

As I'm starting to learn, that is the heater core drain hose?

Heater core is inside the car. Do is your passenger side footarea wet? if it is then its your heater core. Your water pump is right infront of your steering pump

So it's perfectly normal then?

Boy, do I feel stupid. I swear I've NEVER seen it dripping water like this. It was like a faucet.

Thanks people. Seriously. Thanks. :applause:

I'd like to say I think it's dumb as hell to design it like that though. It drips water/moisture right into the cars structure, right off that round shaped bar. It's all rusty and pools up on that crossbeam.
