My car is losing coolant but i dont see any leaks. I just know its all gone by the next day. Do you guys know what can be wrong??

 

Sounds like your head gasket is cracked by the oil and coolant passages, does your oil look milky?
Or does your coolant look milky?

 

....or white exhaust smoke?

 

No my oil is just fine, thanks.

 

Nope no white exhaust smoke.

 

^^^ thanks

bump please

 

if you are going through all your coolant in only a day there is a problem. If there is no smoke, and your oil looks good you probbaly arn't burning any. That means it must be leaking from somewhere. Keep an eye out for a leak or park over something so you can get an idea where its comming from. If none is leaking you must be buring it. It's one or the other, pretty sure it's not disapearing.

 

Check and open your oil cap and look inside it, if there is milky residue, then you have a bad head gasket, My oil didn't look like it didn't have any milky residue but, when I looked at my oil cap, it was full of milky residue. Look also for clogged hoses. Check the heater hose and the one at the intake manifold for any cracks and or unusual swelling. In addition, check for cracks on your radiator. Hope this helps a bit.

 

i just did my oil change 2 days ago, didnt see nothing guys.

 

could it be my thermostat ?

 

it use to leak from the top, but that was because the clip was loose.

 

there could be a hole in the radiator that you can't see, it happened to me before

 

From the top of what? What clip are you talking about?

 

or maybe the drain nut on the bottom is loose.

 

but if there was a hole it would be leaking, wouldn't it?

 

it was leaking from the top of the coolant container. inside theres a tube and it has a clip that stops the coolant from rising

 

I had this happen to my accord and I couldnt figure out where the leak was and found that it was a heater core hose that was the smallest slit. I realize you said it wasnt leaking, but I would check those two hoses on the back of the engine.

 

Like a few people posted above, check your radiator first, if your loosing coolant like that its possible that you may have a crack in your radiator that you cant see, i would start there before i even looked anywhere else, same thing happened to me , i had a crack rite in the front on top of the radiator that i couldn't see, and i was loosing coolant like whoa, especially when my car was parked.

 

but if there was a crack it would leak, right??

 

i've only noticed it leak, when it was coming out of the lid of the coolant container because the clip wasn't on tight. Other than that i dont see any leaks.

 

when i get home from a long drive, i turn off the car and i could hear it bubbleing.

 

my stock radiator had a small crack in the plastic tub at the top. it didn't leak fast, but it would steam out of the crack. my car began overheating to let me know something was wrong.

you could have a hole in the radiator or a hose that isn't at the bottom of the part that would allow it to drip. some leaks will only bleed off the coolant when its all hot and pressurized, like mine was.

 

Great way to check for a leak to is to go grab a big chunk of newish cardboard... aka raid walmart's cardboard bin... and put it under your car, leave it for a night and you can pretty much pinpoint it.
Please forgive me as I am fairly new to the Honda/acura scene, but do they have softplugs? My 240 had a cracked softplug that would only leak if there system was running. Just a few ideas.
