i have not found a drop on the groudn or inside the engine bay. i filled up the overflow two days ago and all i do is drive my car 5-10 miles a day. i just fille dit up all the way again yesterday? can anyone help me? i have a brand new radiator and the upper hose is new too.

 

check your radiator cap... i bet its not sealing and its just evaporating from there. Trust me its happend to more than one person i know... and they always spend days looking for the culprit... replacing T-stats, radiators, and alike.

 

i have a shitty autozone cap on my nice koyo radiator, and when it gets hot, you can see that **** evaporating up. i need to get some distilled water and a better cap.

 

or it could be the thing i dont wanna say the head gasket might be bad and maybe letting coolant go into the engine. do you have any white smoke coming out when you rev? or at idle?

 

your hoses could be leaking, your heater core could be leaking
thermostat, radiator cap.. check the ground where you park, have your friend drive behind you when you romp on it look for white smoke.

 

Pressurize the cooling system and check for leaks.

A faulty rad cap is typical.
If all that checks out then you have a serious problem.

 

i had the same problem with my 94 civic it ended up being the head gasket and the cylinder head warped and the 2and 3rd cylinders were cracked so hopefully its not that bad but check if you anti freeze if it is dark or has black spots that means yuu have a head gasket prob or cracked cylinder or you could go to auto zone and get a black light dye and put it in your antifreeze and see where its pissing out

 

I had similiar problem. No leaks visible.

I changed water pump. And it dissapeared, no leaks since. Try it.

 

check the cap and if that doesnt work do a pressure test. and does your car over heat when you drive it for a long period of time. if so you popped the head gasket

 

mine was leaking into the cylinders and only white smoke out the tail pipe no leaks

 

I had the same problem in my D-15, and it turned out to be a heater hose leading to the back of the TB.

Small drip, and the engine had to warm up to find it.
