Does it only come on when you start the car? Does it come on when the car is idling for a little while?

Check this thread and see if it might be something like you are seeing:

ive only driven teh car liek 5 times since i got it, since teh weatehr hsa been gettign worrse i dont drive it, but 3 times or 4 out of those 5 that i drove it everytime i started it about 5 secs later teh coolant buzzer/light go on abotu 10 sec later they stop and after taht i never get it while on light or driveng..never. i havent been stuck in traffic yet so not sure if it wil do it if it sits there and idles for alittle while. though it does smell like i am burning antifreeze once in a while. i belive i saw smoke comming out from where my right headlight is i loked at teh water temp gauge immidiately and it was right below teh middleso it wasnt overheating i pulled over and popped the hood. saw nothign unordinary. ive had the car for about 2 weeks. i will be gettign an aftermarket water temp gauge but lookign at stock one it doesn tseem to be overheating. once after driving i came back home poped the hood and was just starign at the engine and i heard liek hissing or poping noises. ive heard thi swas normal. thats about all for my expirince withteh car so far.

Try this first. BEFORE you start your car the next time, while the engine is cold, pop off the top of the Filler Neck for the coolant (see if there is any pressure release when you pull it off). Also open up the coolant cap as well. Leave them off for a minute to allow pressure to escape.

Put them back on. The first time you start your car, the coolant light/alarm should go off. Drive it around for a while to allow the cooling system to pressurize again. The next time you start the car, see if the coolant light/alarm goes off again.

ok thanx ill try that

When you check the AST ( tank with the 13psi cap on it) or the water pump filler neck (the one with the cap with no spring) are the levels up to the top ??? If they aren't then you might be getting air into the cooling system causing localized boiling and causind coolant to be pushed into the overflow resivoir (under right head lamp) this is not good....the temperature gauge is worthless as when you see it move off the half way point the engine is already overheated. You need to make sure everything is topped off and your overflow tank is to the full mark. If all is full then the light and buzzer should not come on.

ok i am gettign confued just a bit. i just checked the radiator level, which is right next to the pass side headlight, that seems leveled off. then i popped both coolant caps the ones located toward the center of the engine, the one closer to the engine had coolant in it but there is some sensors that i noticed and coolant wasnt up to that level i guess thats the low coolant level sensor. then i checked the little tank coler to the bumper there was coolant there but not completely topped off so i added some in there as well. btw both caps were spring loaded.

You should only have one cap that is spring loaded, that is the one on the little tank next to the Intercooler (should be .9 bar or 13 lb's) the one on the engine should not have a spring in it and you overflow tank (right headlight) should be at the full mark. The sensor you saw is the low coolant level and this explains why your buzzer was going off, once the coolant comes up to teperature and expands the sensor is covered. This also means there is air moving around you cooling system and this is not good they should always be topped off and once the air is out shouldn't need attention. The factory temperature gauge is junk as it will only move off the center portion of the gauge when the car has started to overheat and will climb very fast. If theres air in your system the gauge becomes even less reliable for temperature and may not indicate an overheated condition. I hope this is helping you as I don't want to confuse you. I think I have some pictures I can email you with some direction on the caps. My email is cjjack56@yahoo.com

as u can see i checked all those and #2 and #3 were both spring loaded everythign was filled up but the #2 had the sensor right above teh antifreeze levelso i guess thats why my coolant light and buzzer woudl go on

Ok you deffinately need to get the cap without the spring loaded plunger in it for the filler neck. The only one that should have a spring is the one on the AST (air seperation tank) mounted to the intercooler (looks like a small radiator.

the one where teh picture is indicating .9 bar i have a 1.1 bar and where u said i need to cahnge this cap to one without a springs is .9 bar

Your engine filler neck (next to air pump) should be a cap with no spring. he cap on the AST should be a .9 bar (next to Intercooler) I'd get the right cap and top off the system (fill AST) put the cap on and then top off the filler neck (next to air pump) and then keep an eye on the level for a couple of day's till it stabalizes. Make sure you overflow resivoir is up to the full mark as well.

the engine filler neck, does a 1.1 bar cap go on it did the previous owner mix them up or do i have to buy a diff bar cap for it?
