What is the cap under the hood with the can with a drip coming out for ? i do not have a manual I am a lady and not sure what this is I know where the oil trans.place is the water , but not sure what this is . it is on top of the motor looking in I see where there is moisture is this where the over flow of water cools the engine ? It is a 2004 Chevy Aveo ?

Your question is rather ambiguous and does not have much detail about what you are seeing. Are you referring to the windshield washer fluid that is supposed to spray on the windshield when you select that function?

The only water that is supposed to be coming from the motor itself is burned hydrogen coming out of the tail pipe (water dripping from the pipe). If you have had water coming out of the engine or its hoses under the hood, and now you don't, you may have just lost a major share of your coolant to a leak, and risk damaging the engine by overheating it. When the engine is cold (never do this when it is hot!), remove the radiator cap and check to see if the coolant level is up to the top of the radiator. If it is not you may have a coolant leak. If so, get the leak repaired ASAP and add the coolant specified by the owner's manual.

Were you seeing the water under the car only when you ran the air conditioning? This is normal in humid weather, the chiller section of the air conditioning condenses water out of the air and drips it onto the ground; however if the air is very dry, any condensation evaporates off of the chiller instead of dripping. If you don't see any water dripping underneath the car when the A/C is running, and the weather is humid, either the A/C isn't working (the inside of the car stays hot), or the condensate drain is plugged up and should be cleaned to prevent corrosion problems.

First of all, it's a VW, so it shouldn't have ANY "neon green stuff", it should have pink G12 coolant from VW. If the leak is getting worse, it's a hose failing, and splitting worse and worse under the cooling system pressure. find the leaking hose and replace it, but I'd recommend using a VW specific mechanic, so the "neon green stuff" doesn't make it back into your car, where it shouldn't be.

If you open the hood, on the drivers side, on top of the
transaxle, you should see a ,say yellow cap, maybe,that
will come out & have a drip stick on it Fill there

Honda & Acura use special fluids,so be careful
Not sure just get at a dealer

Yes it is.If you need to know for sure follow the small overflow hose underneath the radiator cap it runs from the radiator to the coolant tank.

2 things :thermostat ,and possible blown hose .. liquid is your antifreeze.. Get a new cap

oil catch pan hydraulic cat and ratchet with metric sockets adjustable filter rachet lift car front get on under with oil pan rachets and on the motors side of the car you'll find a bolt on the crank pan just a lonley screw on the bottom of a pan close to where your under loosen screw first then put oil pan under try and loosen screw slowly so when it lets go you can cntrol the flow a little so the oil pan can be put in the proper place to catch the oil let it empty till there is nothing but droplets return screw and tighten back on do not over do it the treads on the pan can be harmed if you over tighten then locate filter put oild pan under filter loosen and the same way as the screw do with the fiter . Before putting in new filter on put some fresh oil on the rubber ring and inside just a little so it goes on smooth your finished under the car now go up top hood open you can put car down by now find oil cap and fill in oil

there isnt one. there is a screw with a hex head on the rear of the transmission just above the transmission oil pan. when you take out the screw the oil will just start to drip out. to add trans fluid on the drivers side under the hood you will see a large black tube that comes off the engine. look just below that down into the engine toward the ground and you will see a red cap about 2 inches in diameter it says transmission fluid on it. you just unscrew it. you will need a long funnel or you will spill

If you don't know where it is coming from, you have to find that out. Check the location of the spot on the floor, if you don't have a floor, put down a piece of cardboard, locate the drip, then look under the hood for what it is that is leaking. It could be the overflow on the expansion tank, could be your AC condensate line dripping, could be one of those tiny coolant lines that return to the back of the engine, could be the water pump, could be a hole in a hose. I don't know why the pressure check didn't show anything, might be something else. Check it out.

I believe this is your windshield washer fluid light. Under the hood, you should find the cap with the same symbol. Put some windshield washer fluid in the tank and the light should go away.

Hope this helps,

I have a similar problem with a 2003 cadillac cts. The water drips from the bottom area of the glove compartment. If you would stick your hand under and feel around, there is a removable panel ( two small bolts and one star screw) there , you will fell the sponge on the other side of the panel is wet. I removed this panel and ran the air conditioner and place a large mirror on the floor and shine a flash light up but did not see any water dripping.
The Driver side has a similar panel, I removed that also but saw nothing, not even the canister. But the out side pipes from the AC show the canister leads in the hood under ther driver side.
Any way I looked under the car and found the drain hose. It is located under the driver seat area. I tried fishing a coat hanger through it and it went a long way up. If you look on the side panel where the parking brake is located you will see this hose going to the top of the hood. You will need to depress the parking brake for a better view. I tried the Ac bot no condensation water came throug.
I late found a similiar hose on the passenger side. I tried to push the wire in but did not get too far.
One of these hoses drain the Sun ( moon) roof.
I then took a cap from a silicone tune ( u know the screw on tip that you cut at 45 degrees) That I inserted into the tube under car, then I insert a small funnel into the silicone cap , next with my garden ready and flowing , I force water up through the AC drain hose. Dont do too long, 5 to 7 secs is good. You will see the water come through the other drain hose. It is best to have some onlookers. Note some water might flow up to the moon roof drain and into the car so place some towel on the seat.
That works for me.
Thanks all
and good luck
