coolant disappearing???

alright...everytime i fill up my coolant resevoir...its gone in about 2-3 days...my engine temp stays normal...i dont overheat...i checked for leaks...none...where is it going?...is the radiator bad?...i have no idea what to do next?..pressure test?..how?

If the coolant isn't dripping/leaking from anywhere, and the hoses and radiator appear ok, then I would guess head gasket. They normally wear out as they get old or with many miles, and it leaks coolant into the cylinder, which burns, so you won't see coolant leaking, but you will be loosing it.

Take it to a radiator shop. The put a special cap on the radiator to check the presure so see where the loss is.

Odd, mine does the same thing. No leaks that I know of or can tell, radiator fluid is still at the top, but the reservoir dissapears after a few days. If the reservoir only connects the radiator, and the radiator stays full at the top, wouldn't it suck some of the radiator fluid out if it was a gasket issue? Seems like common sense there to me unless I'm missing something.... Also I doubt it's a gasket with me anyways since I only have 31k miles on my car, and my temp never overheats either.

I had the same problem
I was having coolant disapearing...
I would drive around normal and nothing would happen.. No leaks i could see.
If i drove around high reving 8-9kpms (getting my engine really hot and really pumping the fluid through the hoses)
I could get out my car and go eat lunch.. come back and have about a 6 inch green puddle under my car but when i went and looked for it I couldnt find anyleaks.

So instead of turning off my car After high reving
I would leave the car running and open the hood and look for any sweet smells and drips.

Turns out my top radiator hose very close to the head had a tiny tiny crack in it, and it was leaking very very slowly onto my transmission,and when it would land on the transmission, it would evaporate.... reason being why there wasnt always a pool of green under my car.

Anyways check your radiator hoses while they are hot.

ill check that..thanks...so the best time would be after hard driving huh?...how much do radiator hoses cost to replace if it is that....yeah last thing i wanna do is check the head gasket...thats a bit of a pain in the ass...last resort check there...someone told me to take it to a radiator shop also..i gotta find one around here..any suggestions?

a single radiator hose will run ya about 6 bux at a part shop
