Need HELP/ADVICE - Water Dripping / Leaking Under Prius

Don't worry about it... it's the A/C. It's August and humid.

Alan,

Condensation is very typical of nearly all A/C systems in most cars I've owned or driven. I've not located the area that the "system" drains from on the Prius yet but what you are describing sounds exactly like condensation drip and is normal. Someone else will post better information I'm sure.

 

I can't remember having a car that didn't drip in humid weather. My Prius is the same as all the rest. Not to worry.

 

Sometimes while waiting in traffic, my car will raise a rear tire and take a leak on the SUV next to me....

 

lol thats a classic!

 

In fact, if you run your A/C , park, pull away later and DON"T see evidence of water you have a problem. Check that drain to make sure it is clear. My local dealer had a car (not a Prius) that had water inside because of a spider clogging up the tube. Lot of damage to the floor material.

 

I have an intimate relationship with the ac evap hose. Its a little black hose located a few inches behind the pass front wheel about 2 feet in. You can just barely reach it if you lay on the ground behind the front pass. wheel. Water should always drip out of it with the ac on. Just like at home.

 

No worries! That's the latest techno device, for future mods. Your prius has its own hydrogen supply unit. All you gotta do is separate the oxygen from it and you have your own permanent fuel source

 

On the subject of A/C, can someone clarify for me whether the system runs on the battery, or the engine?

 

The compressor is electric, so it runs off the high-voltage battery. When that is drained, the ICE will kick on to recharge, but one can sit in Park and "Ready" mode with the AC on and the ICE off, until the battery needs recharging.

 

thanks

 

I have the same complaint in the same model. I bought this car around 15 days ago and I am in a waarranty of 3 months from the dealer so I am afraid about that.
Please I need reassurance from you.
It is colourless, odourless, not oily fluid, from under the engine passenger side.

Welcome to PriusChat!!

Given the time of year and your location, one might guess your water pump in leaking.

Now would be a great time to check all of the fluids in the vehicle, before driving it again.

When checking fluid levels for the engine, be sure to check the radiator and not just the overflow container.

Do you have a copy of the owner's manual?

How many miles of this vehicle?

Have you asked the local "Toyota Dealer" for a print out of this vehicles maintenance and recall history?

 

If it is colourless, odourless, not oily fluid, it may just be condensate run off from the air conditioner. Being a RHD, that would be from under the engine LHS, yes?

Do you use the A/C?

 

Hello,
Kind of a dead post but I’m having the same issue. Normally I would call it condensation from the AC. But I haven’t been running the AC as it’s winter. I’ve been using the defroster. After a 45 min commute I notice not long after parking that about a 8 ounce dip session begins. It’s colorless, odorless, and not warm. Any help would be appreciated. It’s been in the mid 40’s here 80% humidity

 

In modern cars, the defroster makes some use of the AC too.

I know my third gen will "stealth activate" AC (the active cooling, compressor running AC) if I set vent mode to heat/defog (the symbol showing windshield and heat to feet). Might be similar on second gen? What mode are you running.

Note: the AC button on mine has a light, which normally indicates when it's on. It's not lit, but I've seen "watts" values other than zero, monitoring with ScanGuage, a few years back.

If you were running heat/defog mode, and wanted to test if AC was running without indication: switch to another mode, say high/low, and see if you get a humidity "dump" within a minute or two.

 

And not only that, but the reason the car turns on the A/C in defog mode is to condense the water out of your 80% humid air, so the windows don't fog. The water goes out the drain hose under the car.
