Question about 2005 Hyundai Tucson

Water dripping from underneath

While backing out of my driveway, I noticed that a puddle of liquid had formed underneath my vehicle... upon further inspection I realized that it was water. I grabbed a flashlight and looked underneath to see if I could find the source. The water was dripping from a short black hose ( approx. 6 inches in length) located beyond the back of the engine compartment. The hose just points straight down with nothing on the end of it..... I looked through my owner's manual but did not find any reference to the hose.... Any idea as to what this hose is for and why it's dripping water?

    I had a feeling it was either that, or an overflow for the radiator.... since the vehicle wasn't running hot, I thought it had something to do with the A/C................ Thanks for your help!

That hose is the drain hose for the a/c. When condensation forms from running the a/c it drains out through the black hose you are refering too.If it doesn't drain out it will eventually overflow inside the car and get your carpet wet.

VW Passat 2.0 Diesel estate. Occasionally,my passenger side,foot well,is sopping wet. I've noticed water seeping from behind the dash,same side. And I have a slight oily smell inside the car although...

Could the liquid be coolant? If so, you likely have a broken heater core. Or... it could be condensate from the a/c evaporator is not exiting via the hose that is designed to take it out of the car (ever notice how a puddle forms under a car that has the a/c on?). If your car doesn't have the puddle, it's because a bug made a nest in that tube (or some other blockage) and the water is overflowing and coming into the cabin.

It is most likely the A/C drain if you have been running your A/C system or have been using your defrosters. (normal operation)

Also, you may want to take a closer look and see if it is dripping from the exhaust. A normal by-product of the chemical reactions going on inside your catalytic converter is H2O. Most exhaust systems on modern automobiles are equipped with drip holes in the resonators and/or mufflers to help prevent severe corrosion of the exhaust system due to the water that is produced..

I have a s60 parked it in car park Friday PM came back to puddle under radiator drove slowly home (only 1 mile) warning coolant low on dash. Filled up with antifreeze/water mix to max level once cooled...

The low coolant sensor is in the resivor where you put the coolant in. Since you drove it such a short distance the thermostat probably did not open to allow the coolant to pass. There is a skid plate underneath the car you can remove to find the source of the leak.

Water dripping right front underneath

Is what the liquid plain water or coolant (water mixed with antifreeze). touch and smell the liquid, no smell = water, antifreeze smell and oily feel = coolant.
If plain water, could be Air Condition condensation dripping from condensation drain which is normal. (this drain is usually located near the center of the vehicle).
If coolant, could be leak(s) from: radiator, radiator hose, heater hose, water pump, engine freeze plug. A coolant system pressure test should show what is leaking.

run the car for 5-10 minutes with ac on full. Move the car to a dry area, shut it off. if the drip continues for a little bit and stops.
That would indicate it is ac coil condensate. Next test, run the car without ac on to confirm above.

My passenger floor board is STAYING soaked... Air is working fine so is the heat... What could the problem be????

There is a drain hose which is ducted to the outside of the vehicle. Normally when you run the AC, do you ever notice water or puddles underneath a vehicle on the passenger when it is hot out? This is condensation derived from your AC system being worked. This is natural. Run your AC and after 10 -15 minutes, you fail to see water draining from the vehicle, the drain is plugged. Turn the vehicle off and look under the vehicle passenger side, on the firewall. Once you locate the drain tube(normally black and pinched at one end as to not allow debris from entering and only water to exit), you will want to get a coat hanger and very carefully insert the hanger and pull out in short intervals to see if leaves(which are the most common)are coming out. If so, continue until a good stream of water is draining, so don't stick your face underneath. If this can not be accomplished, the blower fan will need to be removed and the area cleaned out. What you are seeing is nothing more than water but, it will mildew! Clean it soon! Let me know if you need further help.

1992 mazda mx3 is overheating. checked thermostat seems to be working. Noticed that the heater started acting up a few days before it overheated......Heater works randomly, seems like you start the car...

Check your coolant. If the coolant is low, you won't get heat in the cabin. Make sure that the fan is turning on as well. Check coolant sensors also. Good luck!

Lossing water

My guess is, it's warm where you are -- correct?

Further, I speculate you've been running your A/C.

The water you see is condensate dripping from the A/C -- normal condition.
