Its not that big of a deal but I would just like to know where its all going... I flushed my system and filled up. About three weeks later my low coolant light came on. So I topped off again, now it just came on AGAIN this morning which will be almost another three weeks. So basically, every three weeks I go from topped off to right below the sensor. Anyone know where the hell all my coolant is going? Ive checked like three times for leaks and found nothing, checked the ground and even got under the car and looked and felt for leaks and couldnt find anything. Also, my heatercore is good so its not that. Any suggestions? Like I said, its not that big of a deal but I would just like to know since its not normal. Thanks guys.

Could be going out the exhaust due to bad head gasket(s). Thats what mine is doing.

I guess its a possibility but I dont think so. Im not showing any signs of blown head gaskets. The car runs fine, no overheating, nothing. Runs perfect.... just loosing coolant like crazy for some reason.

mines doing the same thing...i'm running straight water though (i know, i know [&o]) so i'm thinking some might be evaporating...

Sounds similar to mine. I dont have an overflow tank on mine so when coolant runs into the overflow hose near the gas cap it just falls on the ground, I THINK thats where mine is going....but yeah mines about every 3 weeks too.

i have same problem. have no idea where it's going and compression test shows all seems fine. no leaks. anyone know?

Mine is the same way.
It never even comes close to overheating and theres no coolant in the oil or oil in the coolant and it runs fine.

It does stink like something burning after driving it awhile though.

i suggest you all do a leak down test....if you are pouring water every top off you might have a little evaporation but nothing serious.

When the water pump goes bad they have a little weap hole in the bottom that will start leaking water. I think it usually only comes out when the car is running so you wouldnt see anything on the ground when it is sitting. And when you are driving it just runs down the front of the motor and evaporates! So you wouldnt notice it there either. Get under the car and look up at your water pump and see if you see a stain under it or it is damp. This would not make your car overheat either its just a sign that the pump is going bad.

you will see coolant when a weep hope blows out......like i said....rent the tool and check for pressure drops
