Water is pouring out as fast as I can pour it in

Get someone to pour in the water and then you crawl underneath and look for the source of the leak. Take a strong flashlight.

Hi I have a 96 toyota camry the car overheated . I tried putting 50/50 antifreeze in and it just poured right back out somewhere by firewall area . I had seen someone talk about a joint inlet ??? I tried...

Looks like the dark well of mysterious things behind my engine, too. A joint inlet would probably be for a heater hose line, probably the inlet line to the heater core, as the outlet from the heater core back to the engine would enter near the engine front near the water pump. Conventionally speaking, that is.

It's all conjecture until you get a good look at it. Judging from the picture, I would be underneath the engine looking up. That means blocks under the side frame or jack stands, don't trust any jack. A flashlight and a small mirror in hand, look for where coolant could pour out. Look for that hose inlet, and check the "freeze plugs"-one may have popped out- these are round castings in the engine block, open to the water jacket around the block where coolant circulates. Good luck, now that you are under the car and dirty, now I don't have to do it.

Car pouring coolant from underneath the radiator

Can be several things. Bad Radiator, Bad hoses on radiator, or nearby water pump is leaking.

They make a Radiator pressure tester which will put pressure in the system so you can see where the leak is coming from.

I have an 01 f150 when I pour water in the radiator it's pouring back out between the motor and trans bell housing out of the dust cover does anyone have any idea what the leak is I figure a freeze...

If you never overheated the engine and it never froze, then most likely a freeze plug has failed. You will need to either pull out the engine or remove the transmission (easier) to inspect the rear of the block. About the only way to crack a block is running it without any water in it and super overheating the engine. If it is a freezer plug, then I would replace it with a brass one if available.

My rodeo started shooting steam out i filled it with coolant and during my 1 mile trip home water was pouring out from underneath,i poped hood,cap was on but steam was coming from below engine,help

Hi there,

Hopefully there is a hole in one of the hoses (least expensive).

No matter what, you need to find the source of the leak. A flashlight will be useful.

When the engine is cool, pour water in the radiator. You shouldn't need to run the engine.

When it starts dripping, look for the leak on:
  • The radiator
  • Large hoses leading to and from the radiator
  • Heater hoses (smaller leading to firewall)
  • Water pump (on the engine)
Once you find it, the severity and type of problem will dictated whether to fix or replace the damaged part.

Water in floor board and I think the drain back hose is stopped up. Thought the windshield was leaking but the insulation was wet right under were the heater hoses go threw the firewall. I poured water on...

While what you are describing certainly could happen, it seems unlikely you'd have water coming from a blocked a/c condensate drain at this time of the year. The a/c will produce condensation when cooling the flowing air to give a comfortable summer time ride. This condensation is drained to the outside (underneath) of the car by the hose you are describing. Unless you live in a particularly hot climate, I don't think this is your problem given the time of the year

I'm thinking it's a better likelihood you've got a leaking heater core. If your turn the defroster on, do you get a whiff of something that smells sweet? (Kinda like pancake syrup). A leaking heater core can funnel this kind of odor up thru the defroster ducts and into your face.

It overheated, smoking and water pouring

If water poured out you probably busted a hose or radiator sprung a leak. Sounds like that and a bad thermostat or water pump went out.
